Repair Manual

SERVICE 013

Safety and working conditions

All rotating parts must be guarded.
The tractor master shield, the driveline guards, and the implement
input connection shields form an interactive guarding system.
Proper use and maintenance of the driveline and shielding
is of primary importance for operator safety.
A high percentage of driveline accidents occur when safety shielding is missing or does not function properly.
Bondioli & Pavesi recommends the use of proper shields
and guards for the driveline, tractor, and implement. Damaged or missing components must be replaced with original equipment spare parts, correctly installed, before using
the driveline.
Use the implement only with the original driveline. The implement input connection shield must be compatible with
the driveline and the application.
To comply with international safety standards, the implement manufacturer shall provide safety sign(s) and instructions stating that guards must be kept in place and the
machine should not be operated with guards opened or
removed. These sign(s) should be used to draw attention
to the possible risks when the guard is unlocked, opened,
or removed.
In addition it is recommended that the implement manufacturer provide a list of the guards, their corresponding
warnings, their positions, and spare parts codes in the instruction manual.
Basic information for safe and correct use of the driveline and shielding are shown in our catalogs and in the instruction sheet provided with Bondioli & Pavesi drivelines.
Safety labels and user’s manuals in alternative languages
are available to meet local requirements.

THE ABOVE INFORMATION
CONCERNS YOUR SAFETY

1.1 - Service

Safety and working conditions
Use the implement only with the original driveline, which is compatible in
length, power capacity, torque limiters, overrunning clutches, and shielding.
The driveline and safety devices are designed specifically for the implement,
and should be used exclusively for this purpose.
Do not exceed the speed and power limits given by the operator’s manual.
Drivelines, torque limiters, and overrunning clutches in this catalog are designed to be used at speeds that do not exceed 1000 min-1.
Do not overload the implement or suddenly engage the PTO clutch. Any
torque limiter or clutch should be installed on the implement end of the driveline. Use the driveline, torque limiters, and overrunning clutches only for their
intended purpose.

All rotating parts must be guarded. Contact with a rotating driveline can
cause death or serious injury. The tractor master shield, the driveline
guards, and the implement input connection shield form an interactive
guarding system.

Ensure that all driveline, tractor, and implement shields are functional and
in place before operation. Damaged or missing parts must be replaced
with the original equipment spare parts, correctly installed, before using
the driveline.

Disengage the PTO, turn off the tractor engine, remove the key, and
check that all rotating parts have come to a standstill before approaching
the implement or performing maintenance work.

1.2 - Service

Safety and working conditions
Do not approach, nor allow bystanders to come near the work zone or
rotating parts. Do not wear loose clothing, jewelry, hair, or anything which
could get caught in the machine.
Contact with rotating parts could cause serious injury or death.

Do not stand, lean, or otherwise come in contact with the driveline. Do not
step over or go under the driveline.

Keep the profile tubes overlapped as much as possible during transport
and operation. Do not exceed the values given in this catalog for permissible length extension. If greater telescoping ability is required, contact
Bondioli & Pavesi engineering.

1/2

Always hitch the tractor to STATIONARY MACHINERY (pumps, hoists,
generators, dryers, etc.). Check the tractor wheels to prevent rolling and
check that joint angles are small and as equal as possible.

Always hitch the tractor to STATIONARY MACHINERY (pumps, hoists,
generators, dryers, etc.) so that the profile tubes are not overextended.
Under all working conditions, extension of the driveline should not exceed
the values reported in this catalog. All rotating parts must be guarded.

1.3 - Service

Safety and working conditions

α1

SINGLE CARDAN J0INTS
When operating, ensure that angles α1 and α2 are small and as
equal as possible. The joint angles may vary widely during turns,
but must never exceed 35° under power or 45° while rotating.
Disengage the PTO when the joint angles become excessive or too unequal. See “Driveline Applications” for more information.

α2

α2
α1

CONSTANT VELOCITY JOINTS
Constant velocity joint can allow large joint angles up to 50° or 80° depending upon the type. These joint angles should only be allowed for brief
periods, for example during turning.
For drivelines with a constant velocity joint on the tractor side and a single
cardan joint on the implement side, the maximum recommended angles
of the single joint are 16° at 540 min-1 and 9° at 1000 min-1 to prevent irregular motion. See “Driveline Applications” for more information.

Attach the shield restraint chains, allowing sufficient slack for the driveline
to move during turns and operation.
Best results are achieved when the chains are attached nearly perpendicular to the driveline guard. Adjust the length to allow articulation of the
driveline in working or transport positions, but avoid excessive slack that
may wrap around the driveline.

When used at night or in poor visibility, illuminate the driveline operating
area.

The tractor printed on the shield indicates the tractor end of the driveline.
Any torque limiter or overrunning clutch must be installed on the implement end of the driveline.

1.4 - Service

Safety and working conditions
Ensure that the driveline is securely attached to the tractor and the implement before operating.
Check that all bolts or nuts are properly torqued.

Friction clutches may become hot during use.
Do not touch!
Keep the area around the friction clutch clear of any material which could
catch fire and avoid prolonged slipping.

Never use the shield restraint chains to support the driveline for storage.
Always use the support on the implement.

Keep the driveline horizontal during handling to prevent the halves from
sliding apart, which could cause injury or damage the shielding. Use suitable means to transport the driveline, depending on the weight.

Always wear adequate safety equipment when performing any maintenance or repair work.
Clean and grease the PTO of the tractor and the implement input connection to facilitate installation of the driveline.
Replace worn or damaged components with the original Bondioli & Pavesi spare parts. Do not alter or tamper with any driveline component. Contact an authorized Bondioli & Pavesi dealer concerning any operations not
described in the instruction manual.

Lubrification
Proper lubrication of all rotating and sliding parts is essential
for proper function, long life, and reliability. Insufficient
lubrication, or contamination of the lubricant, is one of the
most frequent causes of failure of cardan joint drivelines.
The lubrication frequency and the type of grease used are
important to the life of the driveline, as well as the shafts and
bearings of the components to which they are connected.
Joints, telescoping members, and shields must be
lubricated at intervals related to the environment and
working conditions.
Grease contains a soap base (lithium, calcium, or sodium
based), lubricating oils, and additives (e.g. molybdenum
disulphide).
These additives are used for corrosion resistance, strength,
adhesion at extreme pressures (EP), or other properties.
The soap base can be compared to a “sponge”; it
retains lubricating oils and gradually releases them to the
components. Its efficiency diminishes with longer working
periods and with higher pressures.
Greases are classified by the National Lubricating Grease
Institute (NLGI) according to their consistency.
Bondioli & Pavesi recommends NLGI #2 grease on all
crosses, telescoping members and shields.
NLGI #2 molybdenum disulphide grease is recommended
for devices that are lubricated only once (e.g. during
assembly) in their entire service life, such as RL overrunning
clutches and LR automatic torque limiters.

The following instructions, that are also listed in the
operator’s manual of the driveline, should be included in
the manual provided by the implement manufacturer.
Disengage the PTO, turn off the tractor engine, remove
the key, and check that all rotating parts have come to a
standstill before approaching the implement or performing
maintenance work.
It is recommended to grease the components before the
initial use.
Clean and lubricate the driveline before storage, and at the
end of the season.
When greasing cross kits, lubricate generously until the
grease purges from all four bearing caps. Pump grease
gradually. Avoid high pressures, especially those possible
from pneumatic equipment.
Clean and lubricate the driveline before storage at the end
of the season. It is also recommended to clean out any
grease inside the CV joint shields.

Disengage the PTO, turn off the tractor engine, remove
the key, and check that all rotating parts have come to a
standstill before approaching the implement or performing
maintenance work.

Always wear adequate safety equipment when performing
any maintenance or repair work.
Clean and grease the PTO of the tractor and the implement
input connection to facilitate installation of the driveline.
Replace worn or damaged components with the original
Bondioli & Pavesi spare parts. Do not alter or tamper with
any driveline component. Contact an authorized Bondioli
& Pavesi dealer concerning any operations not described
in the instruction manual.

How to shorten and driveline
Determining the correct length

To determine the correct length of the driveline, it is
advisable to hook the machine to the tractor and place
the machine in order for it to be at a minimum distance
between the power takeoffs.
Install the two uncoupled and unprotected semi-shafts
to their respective PTOs.
At this point, verify any interference of the outer pipe with
the yoke inner pipe and establish how much the outer
pipe needs to the shortened.

Transported machines

In transported machines, the minimum distance Dmin
between the joints occurs when the PTOs are aligned on
the vertical plane.
Verify that, in the condition of maximum extension, which
generally occurs when the machine is lifted, the coupling
between the two pipes is sufficient.

Towed machines

In towed machines, the minimum distance Dmin between
the joints occurs during steering.
Verify that, in the condition of maximum extension,
which generally occurs when the machine is aligned, the
coupling between the two pipes is sufficient.
When determining the minimum and maximum lengths
and during subsequent verifications, it is important to
bear in mind that ground subsidence may cause further
reduction and increase of the distance between the
PTOs.
Bondioli & Pavesi does not recommend modifications
to its products. If the driveline needs to be shortened,
proceed as described below. If you are unsure of the
procedure, or need additional assistance, please contact
your local implement dealer or qualified service center.
1. Remove shielding.
2. Shorten drive tubes by the required length. In normal conditions, telescoping
tubes must always overlap by at least a 1/2 of their length. During manoeuvres,
when the driveline is not rotating, the telescoping tubes must have a suitable
overlap to maintain the tubes aligned and allow then to slide properly.
If the driveline is fitted with a single chain restraint system (splined inner tube),
the tubes can be shortened by a limited amount (normally no more than 70
mm) to avoid eliminating the splined ring connecting the two shield tubes.
If the driveline is fitted with a greasing system incorporated in the inner drive
tube, the tubes can be shortened by a limited amount to avoid damage to
the lubrication system. Carefully measure and shorten each drive tube equally.

10.1 - Service

How to shorten and driveline
3. Carefully deburr the ends of the tubes with a file and remove any
chippings from the tubes.

4. Shorten shield tubes one at time by cutting the same length that was
cut from the drive tubes. If the driveline is equipped with Single Chain
Restraint System, shortening the driveline will involve removal of the
plastic ring which con-nects the shield tubes. If it is necessary to
remove this collar, ADD A RETAINING CHAIN TO THE TRACTOR
SIDE OF THE DRIVELINE SHIELD.

5. Grease the internal drive tube. Reassemble the shielding on the
driveshaft.
ATTENTION: SFT drivelines with 4-tooth profiles must be reinstalled
in such a way that the grease fittings on the cross kit bearings are
aligned.
ATTENTION: by reducing the drivelines equipped with “Free Rotation”
profile pipes, the lowering, which prevents the incorrect coupling
between the two semi-drivelines, is eliminated.

To prevent uneven motion transmission, the two semi-drivelines must
be reinserted in such a way that, under load, the inboard yokes are
co-planar and not displaced by 60°.
6. Check the length of the drive shaft at the minimum and maximum
positions of the machine. Telescoping tubes must always overlap by
at least a 1/2 of their length. During manoeuvres, when the driveline
is not rotating, the telescoping tubes must have a suitable overlap to
maintain the tubes aligned and allow then to slide properly.

Restraint chains
Restraint standards and regulations
UNI EN ISO 5674 standards state that restraints must
withstand a load of 400 N, and must detach at the end
attached to the shield at loads of under 800 N.
ASAE S522 standards specify proper functioning at a
load of 400 N and separation at the shield end.
Bondioli & Pavesi cardan drivelines are available with two
types of chains:
- Chains with S-hook;
- Chains with Spring Link.
Both S-hook and Spring Link connections separate the
chain from the shield in compliance with UNI EN ISO
5674 and ASAE S522.
If the chain detaches, a chain with S-hook needs to
be replaced, while the Spring Link can be put back as
shown in the following page.

Overrunning clutches
The overrunning clutch is available in two versions: RA and
RL.
The RA version is equipped with a grease fitting and
requires lubrication every 50 hours, using an NLGI 2
consistency grease.
The RL version is equipped with a special sealing ring
and a seal plate in the hub to prevent lubricant leaks and
contamination.
RL overrunning clutches are lubricated using NLGI 2
molybdenum disulfide grease during assembly; they do
not require further lubrication and this is why they are not
equipped with grease fitting.
The overrunning clutch is made in three dimensions, which
differ for the pawl length and for the fastening system to
the PTO.
- RA1 and RL1
Fastening by means of a push pin (RA1)
and ball collar (RL1).
- RA2 and RL2
Fastening by means of tapered bolt.
- RL3
Fastening by means of tapered bolt.
RL3 overrunning clutches are equipped with a ball bearing
that keeps the hub aligned to the housing during their
relative rotation.
For sizes SH and S0, the RL3 overrunning clutches are
equipped with four pawls instead of the three used in the
other models.

LB shear bolt limiters are integrated devices that cannot
be separated after assembly. Components supplied as
spare parts include the complete torque limiter, shear bolts
(packaged in quantities of five pieces, including the nuts),
push-pins or taper pins, and grease fittings.
Size S1 and S2 shear bolt LB torque limiters are lubricated
during assembly, and no additional lubrication is required
(no grease fitting).
For other sizes it is recommended to lubricate every 100
hours of use.
The grease is necessary to lubricate the surfaces of the
hub and yoke that rotate independently after the bolt has
sheared.

Shear bolt torque limiter
Bolts used on standard LB shear bolt limiters are metric class
8.8, steel, with a minimum strength (Rm) equal to 800 N/mm2.
ISO standards and SAE standards (for USA) for shear
bolts with corresponding strengths (Rm) are tabulated to
the right.
The setting is increased by approximately 20% when
replacing the standard class 8.8 bolt with one of the same
diameter but class 10.9.
Standard bolts are partially threaded, and the nominal
settings usually are referenced to shearing on the unthreaded shank of the bolt.
The nominal setting is reduced approximately 20% when
replacing the standard bolt with another of the same class,
but will shear on the threaded portion of the bolt.
For the safety of the operator and reliable
function of the driveline, replace the bolt only
with one equal in length, diameter, and grade
as the original.

Release System
All the models of FT friction clutches are available with
Release System, that permits reduction of the pressure
on the linings during storage without disassembly of the
clutch. The system also permits verification of proper
operation after storage.
Pressure on the linings is reduced to a minimum by turning
four socket headed screws (located on the flange yoke)
completely into the flange yoke.
When turned completely out, the original pressure and
torque setting of the clutch is restored.
The screws are only threaded on a portion of their body, so
they are captured in the clutch and can be removed only
upon disassembly of the clutch.
All friction clutches with the Release System are equipped
with a hex wrench (code 399000030) to adjust the screws,
and an operator’s manual (code 399FRR001) to explain
the proper use of the system.
To check proper function of a friction clutch with the Release
System, the four socket screws are turned all the way in.
Start the PTO at low sped so the clutch will slip for two or
three seconds (longer slipping may cause damage). If the
clutch will not slip after two or three attempts, disassemble
the clutch and clean the contact surfaces, and replace any
damaged parts.
Before operating a clutch with the Release System,
pressure on the linings must be restored by turning the
four set screws completely out.
The FT friction clutches with Release System are identified
by the letter R at the end of model’s name.

1. Apply a small amount of grease onto the bushing surface and install
it on the flanged yoke.

2. Install all the other components in the sequence shown in the
exploded view.
ATTENTION: If the device is equipped with a“release system”,
tighten the 4 Allen screws first and then all the other components.
The Allen screws must be fully tightened onto the flange yolk to
prevent them from coming into contact with the thrust disc when
tightening the bolts.

3. Insert the 8 screws with their head resting on the flange yoke.
4. Tighten all the nuts until they are in contact with the springs.

5. Tighten the bolts progressively (e.g., half a turn for each bolt) in order
to compress the spring evenly until it adheres to the metal spacer
band.
Appropriate adhesion is obtained by tightening the bolts
until the Belleville spring blocks the band and by loosening
each nut by 1/4 of a turn.
According to the limiter model, the tables on the following page show
the necessary spring codes to obtain the indicated calibrations.

Do not over-tighten the bolts; this may endanger the function
of the clutch.
Bondioli & Pavesi reccomends to not modify the torque
setting estabilished by implement constructor - damages to
implement, driveline or tractor may occur.

Combination friction torque limiters
and overrunning clutches
Three versions of combination friction torque limiter and
overrunning clutch are available: FNV (adjustable), FFNV
(adjustable), FNT (non-adjustable). They have two different
diameters:
- 34 (D = 180 mm),
- 44 (D = 202 mm).
All versions are available with treated hubs and driving
plates to reduce corrosion and help prevent seizure.
The chart below indicates the diameter D, number of
linings, il sistema di fissaggio e il tipo di molla montata.

DISASSEMBLY
The procedure refers to the operations for disassembling an FNT34
friction limiter with built-in overrunning clutch. The other models can be
disassembled in the same way.
The components are not painted to allow the images to be clearer.
1. Remove the grease fitting.
2. Disassemble the clutch according to the procedures shown in
chapters:
- For FNV see chapter 19 “FV friction limiters”;
- For FFNV see chapter 20 “FFV friction limiters”;
- For FNT see chapter 21 “FT friction limiters”.
3. Remove the seal plate at the bottom of the hub.
Use a pin punch to carry out this operation. Fit it into the hub, inside
the central hole of the cover and hit it.

4. Loosen the screws that tighten the cover.

5. Remove the overrunning clutch hub, keeping the pawls pressed.
Upon removing the hub, slowly release the pawls.

6. Verify the efficiency of all the components.
Replace any worn or damaged components with original Bondioli &
Pavesi spare parts.

ASSEMBLY
The procedure refers to the operations for assembling an FNT34 friction
limiter with built-in overrunning clutch. The other models can be assembled
in the same way.
The components are not painted to allow the images to be clearer.
1. Grease the overrunning clutch and the pawl housings on the hub.

2. Insert the springs and the pawls into the hub in the illustrated position.

3. Compress the pawls and insert the inner hub into the overrunning
clutch housing.
We recommend using a metal band to keep the pawls in place while
fitting them.

4. Put a drop of threadlocker on each screw and tighten the cover by
means of the appropriate screws on the rear part of the hub.
ATTENTION: The spare screws supplied with the kit, which includes
also the hub with a tapered bolt and the cover, are already provided
with threadlocker.
5. Ensure overrunning clutch’s proper operation

6. Remove the seal plate (7).
The cover may have to be replaced should the disassembled one be
deformed. The cover must adhere to the inner surface of the hub to
prevent grease from coming out from the hub and onto the friction
discs.

23.5 - Service

Combination friction torque limiters
and overrunning clutches
ASSEMBLY
The seal plate must fully enter into its housing to prevent the
overrunning clutch grease to reach the friction discs.

7. Assemble the clutch according to the procedures shown in chapters:
- For FNV see chapter 19 “FV friction limiters”;
- For FFNV see chapter 20 “FFV friction limiters”;
- For FNT see chapter 21 “FT friction limiters”.
To adjust the calibration, refer to the tables shown on the following
pages.
ATTENTION: Ensure that the friction discs and the metal surfaces in
contact with them are clean. The presence of dirt or grease may
compromise the final friction calibration value.
8. Tighten the grease fitting and lubricate the device.
