Fig. G.6 When the splined shaft is assembled to the drive shaft it is essential to see that the forked
yokes on both shafts have their axes parallel to each other. In other words, the yoke (A) must be in
alignment with the yoke (B), and the flange yoke (c) must be in alignment with the flange yoke (D)
G.8 MODIFIED PROPELLER SHAFT
Coincident with the introduction of the modified power unit (15GD series) described in Section A.44, a
propeller shaft incorporating a splined sliding joint at its front end was fitted.
In addition to the nipples fitted to each universal joint, a nipple is also provided on the sleeve yoke for
the lubrication of the sliding joint splines. This nipple must receive attention every 3,000 miles (5000
km.) with the gun filled with lubricant to Ref, C (page P.2).
Instructions given for the servicing of the earlier propeller shaft apply, in the main, to the modified
propeller shaft. The following points, however, should be noted:
1. In order to remove the propeller shaft it is necessary to remove the four nuts and bolts
securing the front universal joint flange to the gearbox flange, as well as those securing
the rear flange to the rear axle flange.
2. Check the sliding splines for wear by attempting to turn the splined sleeve yoke in relation
to the splined shaft. If excessive circumferential movement is present a reconditioned
propeller shaft assembly will be required.
3. When fitting new universal joints, it will be found helpful to separate the two parts of the
propeller shaft at the sliding joint.
4. Before refitting the splined sleeve yoke to the shaft push the threaded dust cover, the
metal washer, and the felt washer over the splines onto the splined shaft. When
assembling the joint ensure that the trunnions of the front and rear universal joints are in
line (see Fig. G.6). This can be checked by observing that the arrows marked on the
splined sleeve yoke and the splined shaft are in line.
5. Fit the propeller shaft to the car with the sliding joint at the gearbox end.
