5. Install lube tube through “keyed” hole in bearing carrier and into machined
pocket in front inner face of housing. Rotate tube so elongated “key” of
tube fits into corresponding “key” in bearing carrier. Properly installed
lube tube will be flush with rear face of bearing carrier.

6. Install cups for rear tapered roller bearings on primary and secondary
shafts into bores in bearing carrier. Tap cups down gently with soft
hammer or brass drift to seat against bearing cones on shafts.
7. Install manifold gasket over alignment studs and against bearing carrier.
8. Push tapered roller bearing cups, with shim retainers, firmly against roller
bearing cones on rear of primary and secondary shafts. Use a depth
micrometer to measure from manifold gasket face to shim retainers.
Measured distance is shaft endplay. Use necessary shims to develop
a shim pack for each shaft to reduce shaft endplay to 0.05 mm to
0.15 mm (0.002 in. to 0.006 in.).
9. Install calculated shim pack at each shaft location with the thickest shim
against bearing cup, followed by the remaining shims, and finally the
spacer against the shims at each shaft.
