*Assembly Of Parts On Bevel Pinion Shaft (Item No. 4)
(a) To prevent bearing "float", pre-assemble the double set of ball bearings (9) for gears (12) & (13) near the center
of the shaft. Determine how many shims from Kit (18) are required between the bearing sets to keep them confined
between the two snap rings you install on the pinion shaft. Remove all parts but keep the required shims with the
bearings and snap rings for the assembly sequence.
(b) To prevent shaft "float", pre-assemble ball bearing (19) onto shaft (4) and install snap ring (20) to retain it. With
the bearing pressed tight against the shoulder of the shaft, determine how many shims from Kit (72) must be slipped
between the bearing and the snap ring to fill the gap. Lay aside the excess shims. Remove the bearing and install the
shims between the shaft shoulder and the bearing to be sure there is no bearing float when the snap ring is again in
place. Leave these parts on the shaft for the following Step (c) procedure.
(c) To prevent shaft "float", hold the shaft (4) (with bearing, shims and snap ring installed as in Step b) in place
inside the housing with the bearing snap ring tight against the housing counterbore. Install gasket (58) and bearing cover
(59) and tighten at least three of its retaining screws. Attempt to move the shaft laterally back and forth to feel if "float"
exists. If it does, add enough shims from Kit (19A) between the bearing snap ring and the housing shoulder to eliminate
all float. Do not add too many shims so that gasket (58) is not properly compressed to prevent oil leakage when cover
(59) is on tight. Remove all parts but keep the required number of shims with the bearing for the assembly sequence.
