SERVICE 013

Safety and working conditions

Proper use and maintenance of the driveline and shielding

is of primary importance for operator safety.

A high percentage of driveline accidents occur when safe-

ty shielding is missing or does not function properly.

Bondioli & Pavesi recommends the use of proper shields

and guards for the driveline, tractor, and implement. Dam-

aged or missing components must be replaced with origi-

nal equipment spare parts, correctly installed, before using

the driveline.

Use the implement only with the original driveline. The im-

plement input connection shield must be compatible with

the driveline and the application.

To comply with international safety standards, the imple-

ment manufacturer shall provide safety sign(s) and instruc-

tions 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 manu-

facturer provide a list of the guards, their corresponding

warnings, their positions, and spare parts codes in the in-

struction manual.

Basic information for safe and correct use of the drive-

line and shielding are shown in our catalogs and in the in-

struction sheet provided with Bondioli & Pavesi drivelines.

Safety labels and user’s manuals in alternative languages

are available to meet local requirements.

All rotating parts must be guarded.

The tractor master shield, the driveline guards, and the implement

input connection shields form an interactive guarding system.

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 specically 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 de-

signed 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 drive-

line. Use the driveline, torque limiters, and overrunning clutches only for their

intended purpose.

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.

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.

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.

Always hitch the tractor to STATIONARY MACHINERY (pumps, hoists,

generators, dryers, etc.) so that the prole 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.

Keep the prole tubes overlapped as much as possible during transport

and operation. Do not exceed the values given in this catalog for permis-

sible length extension. If greater telescoping ability is required, contact

Bondioli & Pavesi engineering.

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.

1.3 - Service

Safety and working conditions

CONSTANT VELOCITY JOINTS

Constant velocity joint can allow large joint angles up to 50° or 80° de-

pending 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 ir-

regular motion. See “Driveline Applications” for more information.

The tractor printed on the shield indicates the tractor end of the driveline.

Any torque limiter or overrunning clutch must be installed on the imple-

ment end of the driveline.

Attach the shield restraint chains, allowing sufcient slack for the driveline

to move during turns and operation.

Best results are achieved when the chains are attached nearly perpen-

dicular 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.

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 un-

equal. See “Driveline Applications” for more information.

1.4 - Service

Safety and working conditions

Ensure that the driveline is securely attached to the tractor and the imple-

ment before operating.

Check that all bolts or nuts are properly torqued.

Always wear adequate safety equipment when performing any mainte-

nance or repair work.

Clean and grease the PTO of the tractor and the implement input connec-

tion to facilitate installation of the driveline.

Replace worn or damaged components with the original Bondioli & Pave-

si spare parts. Do not alter or tamper with any driveline component. Con-

tact an authorized Bondioli & Pavesi dealer concerning any operations not

described in the instruction manual.

Keep the driveline horizontal during handling to prevent the halves from

sliding apart, which could cause injury or damage the shielding. Use suit-

able means to transport the driveline, depending on the weight.

Friction clutches may become hot during use.

Do not touch!

Keep the area around the friction clutch clear of any material which could

catch re and avoid prolonged slipping.

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

Always use the support on the implement.

Lubrication

Proper lubrication of all rotating and sliding parts is essential

for proper function, long life, and reliability. Insufcient

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 efciency diminishes with longer working

periods and with higher pressures.

Greases are classied 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.

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.

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.

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 sufcient.

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 sufcient.

When determining the minimum and maximum lengths

and during subsequent verications, 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 modications

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 qualied 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 tted 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 tted 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 le 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 proles must be reinstalled

in such a way that the grease ttings on the cross kit bearings are

aligned.

ATTENTION: by reducing the drivelines equipped with “Free Rotation”

prole 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.

Overrunning clutches

The overrunning clutch is available in two versions: RA and

RL.

The RA version is equipped with a grease tting 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 disulde grease during assembly; they do

not require further lubrication and this is why they are not

equipped with grease tting.

The overrunning clutch is made in three dimensions, which

differ for the pawl length and for the fastening system to

Shear bolt torque limiter

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 ve pieces, including the nuts),

push-pins or taper pins, and grease ttings.

Size S1 and S2 shear bolt LB torque limiters are lubricated

during assembly, and no additional lubrication is required

(no grease tting).

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.

SFT Setting Global 100 Setting BOLT COUPLING

Series Series Series

The torque setting, assigned according to type and size of telescoping members, must never exceed the maximum torque

of the driveline.

As for S2, S4 and S6 shafts, which can be equipped with 4-tooth or Free Rotation pipes, the calibration values marked with

(^) indicate the maximum values recommended for Free Rotation pipes.

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 un-

threaded 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.

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 verication of proper

operation after storage.

Pressure on the linings is reduced to a minimum by turning

four socket headed screws (located on the ange yoke)

completely into the ange 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 identied

by the letter R at the end of model’s name.

ASSEMBLY

The procedure refers to the operations for assembling an FT34 friction

limiter. The other models can be assembled in the same way.

The components are not painted to allow the images to be clearer.

1. Apply a small amount of grease onto the bushing surface and install

it on the anged 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 rst and then all the other components.

The Allen screws must be fully tightened onto the ange yolk to

prevent them from coming into contact with the thrust disc when

tightening the bolts.

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.

3. Insert the 8 screws with their head resting on the ange yoke.

4. Tighten all the nuts until they are in contact with the springs.

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 ssaggio e il tipo di molla montata.

Friction clutches may become hot during use.

Do not touch!

Keep the area around the friction clutch clear of

any material which could catch re and avoid prolonged

slipping that will generate excess heat and wear.

FNT friction clutches are available with Release System.

This system permits the spring pressure to be reduced

during storage, without requiring disassembly of the

torque limiter.

Drivelines with FFNV clutches (with coil springs)

are not EU marked because the shield does

not cover the entire inner yoke as required by

Machinery Directive 2006/42/CE.

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.

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

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

tting them.

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

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 nal friction calibration value.

8. Tighten the grease tting and lubricate the device.
