To Examine And Check For Wear; Reassembling The Shaft; Replacing The Propeller Shaft - MG MGA Twin Cam Workshop Manual

G.5 TO EXAMINE AND CHECK FOR
WEAR
The parts most likely to show signs of wear after
long usage are the bearing races and the spider
journals. Should looseness, load markings, or
distortion be observed, the affected part must be
renewed complete; no oversized journals or
races are provided.
It is essential that the bearing races are a light
drive fit in the yoke trunnions. In the event of
wear taking place in the yoke cross-holes,
rendering them oval, the yokes must be
renewed. In case of wear in the cross holes in
the fixed yoke, which is part of the tubular shaft
assembly, it should be replaced by a complete
tubular shaft assembly.
Fig. G.5 When replacing the gasket retainer, use
should be made of a hollow drift to tap it into
place without damage
G.6 REASSEMBLING THE SHAFT
See that all the drilled holes in the journals are thoroughly cleaned out and free of grease or oil.
Assemble the needle rollers in the bearing races and fill with lubricant to Ref. C (page P.2). Should
difficulty be experienced in retaining the rollers under control, smear the walls of the races with
lubricant to Ref. C (page P.2) to retain the needle rollers in position while reassembling.
Insert the spider in the flange yoke, ensuring that the lubricator boss is fitted away from the yoke.
Using a soft-nosed drift, about in. (8 mm.) smaller in diameter than the hole in the yoke, tap the
bearing into position. Repeat this operation for the other three bearings. Replace the circlips and be
sure that these are firmly located in their grooves. If the joint appears to bind, tap lightly with a wooden
mallet; this will relieve any pressure of the bearings on the end of the journals.
It is always advisable to replace the cork gasket and the gasket retainers on the spider journals by
means of the tubular drift shown in Fig. G.5. The spider journal shoulders should be shellacked prior to
fitting the retainers, to ensure a good oil seal.
G.7 REPLACING THE PROPELLER SHAFT
Wipe the faces of the flanges clean and place the propeller shaft in position on the car. Ensure that the
flange registers engage correctly, that the components are replaced in exactly the same relation as
before removal and that the joint faces bed down evenly all round. Insert the bolts and tighten the self-
locking nuts.
