Preparation
Note:
2.1
This task is to be undertaken by suitably trained and qualified service personnel only.
Preparation of Flexible Coupling
Before the installation begins the flexible coupling can be prepared for installation:
1.
The flexible coupling is inspected disassembled.
2.
The coupling hub is lifted into the oven and heated to 250oC/482oF for three hours to give
sufficient clearance when it is installed on the gearbox shaft.
3.
Fit coupling hub on gearbox shaft and allow to cool.
4.
Bolt up hub to the rubber disc with vulcanised metal sleeve. Torque settings for hub bolts on
the AC 11 F2 coupling are for M24 bolts (grade 8.8) 710 Nm.
5.
The flange which connects the rubber disk to the flywheel joins by means of an internally
toothed aluminium ring. The torque settings for the bolts securing the SAE 21 flange to the
flywheel are M16 (grade 12.9) 210 Nm.
Note:
To carry out the gearbox to engine alignment checks the flange should be dismounted
off the rubber disk, therefore do not bolt up the flange to the flywheel disk at present –
leave it hanging from the coupling hub/gearbox shaft.

mounts must be installed and set-up before commencing the alignment procedure, as detailed
below:
2.3
1.
Lift engine onto bedframe using appropriate lifting equipment.
2.
Line engine square to the bedframe and fit bolts.
3.
Tighten bolts to correct torque setting. M24 bolts (grade 8.8) are set to 670Nm.
Preparation of gearbox coupling
The gearbox coupling is supplied completely assembled with protecting grease on the gear mesh
which should be removed before assembly.
2.3.1 Disassembly
For the disassembly procedure there are two sections to refer to, depending on reader’s
preference. Refer to either Section 5.6 (gearbox shear pin coupling component) or Section 5.7
(gearbox shear pin coupling disassembly and re-assembly instructions). A summary of the
disassembling process for the coupling is as follows:
2.4
Page 2-2
1.
Loosen the nuts (19) and remove bolts (18).
2.
Remove screws (21) and sleeve (3).
3.
Remove the retainer ring (27) and the wire that connects all the shear pins (8) so that the
shear pins can be removed.

6.
Remove the retainer ring (23).
7.
Using pulling equipment remove the assembly, which houses the inner bearings (4, 9, 11, 12,
13, 20, 22, 31) – see Section 5.8.
8.
The shaft (6) is joined to the rigid hub (5) by means of screws (25). Remove the screws (25)
in order to have the rigid hub (5) free for installation on the alternator shaft.
Fitment of Alternator Hub
1.
Check that the coupling hubs and shafts are free from nicks and burrs. Check that the bore
and shaft are clean and are the correct dimensions.
2.
Install the rigid hub (5) on the alternator shaft. For an interference fit ISO H7/m6
(0.005inch/inch) the hub requires to be heated to at least 110°C/230°F. The hub should be
heated for 1½ to 2 hours to provide sufficient clearance for fitting, but this is only an
approximate guideline. Install the hub (5) and check that the shaft is flush with counterbore of
the hub.
3.

Alignment Procedure
Note:
This task is to be undertaken by suitably trained and qualified service personnel only.
Radial, angular and axial alignment of the gearbox and alternator in the horizontal axis can be
adjusted by turning the horizontal jacking screws, which are fitted at each corner of the gearbox
and alternator feet. Radial and angular alignment in the vertical axis can be adjusted by adjusting
the vertical jacking screws and shimming under the gearbox and/or alternator.
3.1
Gearbox to Engine Coupling
3.1.1 Radial Alignment (Vertical/Horizontal)
1.
Refer to Sections 5.1 to 5.3 for alignment information, clock gauge set up illustrations and an
illustrated demonstration of how to carryout and calculate the coupling alignment.
2.
Lift gearbox onto bedframe using appropriate lifting equipment.
3.
Set-up the clock gauge as in Section 5.2 with the gauge attached to the coupling hub (fitted
on the gearbox shaft) and the probe in contact with the outer diameter of the flywheel at TDC
(top dead centre). There should be enough clearance to attach the clock gauge and just
enough surface on the outside diameter of the flywheel for the probe to make contact. Zero
the gauge at this point.
4.
Rotate the flywheel via the barring gear using a ¾ inch drive ratchet (the flywheel rotates and
coupling hub remains stationary). Rotate one complete revolution taking readings at four
points 90° apart (these readings include the zero reading already taken).
5.
Calculate any radial misalignment in the vertical and horizontal axes.
6.
Depending on the misalignment offsets calculated, align the gearbox to engine as
appropriate. It may be preferable to align in the horizontal axis to start with by turning one set
of jacking screws (there are two screws/plates for each direction) simultaneously. The vertical
alignment is obtained by adjusting the vertical jacking screws and shimming the gearbox as
necessary.

3.1.2 Angular Alignment
Page 3-2
1.
Refer to Sections 5.1, 5.2, 5.3 and 5.4 for alignment information, clock gauge set up
illustrations and an illustrated demonstration of how to carryout and calculate the coupling
alignment.
2.
With the clock gauge still attached to the coupling hub, place the probe so that it makes
contact with the flywheel face (on the outer edge of the face) near TDC (top dead centre) of
the flywheel.
3.
Rotate the flywheel as before taking four readings (zero at 0/360°, 90°, 180° and 270°).
4.
From the readings at 0/360° and 180° calculate the angular alignment in the vertical axis, and
from the readings at 90° and 270° calculate the angular alignment in the horizontal axis. An
example follows (also see Sections 5.4 and 5.5 for calculation illustrations).
5.
The example shows that the angular misalignment was within tolerance and no further
adjustment/shimming was necessary. If the angular alignment is out off tolerance then
shimming or jacking of the gearbox may be required.
6.
Once the radial and angular alignment checks have been completed on the gearbox, torque
the holding bolts to their correct settings to firmly secure the gearbox in place using Loctite
242 on bolts.
7.
Recheck the alignment once the bolts have been tightened down and if it is still within
tolerance connect the coupling flange back onto the rubber disk and bolt onto flywheel.

Alternator to Gearbox Coupling
The better the alignment the longer the coupling life, with the exception that a slight angular
misalignment (0.05°) is advised in order to have good lubrication conditions.
3.2.1 Radial Alignment (Vertical & Horizontal)
1.
Section 5.9 illustrates the set up of the clock gauge for measuring any radial misalignment.
Attach the gauge to the hub (4) with the probe contacting the opposite hub (1) alignment
surface. Rotate the hub on which the clock gauge is attached and take four readings 90°
apart. The vertical and horizontal offsets should be less than 0.15 mm (0.006 inch).
2.
Using the alignment plates and jacking screws, which are mounted around the alternator,
align/shim the alternator to the gearbox to meet or better the specified offset.
3.2.2 Angular Alignment
1.
Section 5.10 illustrates the set up of the clock gauge for measuring the angular misalignment.
2.
Attach the gauge to the hub (4) with the probe contacting the opposite hub face (1) surface.
Rotate the hub on which the clock gauge is attached and take four readings 90° apart to
measure the Z and Y offsets shown. The difference between Y – Z should be less than 0.20
mm (0.008 inches). Align by jacking/shimming alternator as required.
3.2.3 Lubrication
1.
Once the coupling has been aligned it must be lubricated before operations can commence.
2.
Before bolting up the sleeves (2 & 3), approximately 70% of the gear mesh grease is to be
hand packed between the hub (4), the sleeve teeth and surrounding area. Cummins part
number for the grease, its grade and supplier brand name is given below:
Cummins Part Number
550226
Supplier Brand Name
Mobil XTC
Grade
NLGI No.1 Lithium Soap Base
Quantity used
1.12 kg
3.
After tightening the sleeve bolts (18 & 19) the remaining 30% of the grease is pumped into the
sleeve injection holes (14). Both the lubrication plugs at 180° must be removed to vent the
inner space (fill from one to evacuate the air from the other). An air lock can result in
incomplete filling or in damage to the seals.
4.
After lubrication tighten the lubrication plugs to 25 Nm.
5.
The purpose of lubricating the bearings is to have a good rotating surface whenever the shear
pins might break. The type of grease and Cummins part number is given below.

Calculation:
Vertical Angle a = inv tan{(0 - 0.05)/(660/2)} = 0.0087°
Horizontal Angle a = inv tan{(0.205 - 0.022)/(660/2)} = 0.032°
Therefore both angles within 0.3° tolerance as per manufacturer's instructions
