22. If removed, install bearing cups (1) in retaining plate (2), or retaining plate (3), or retaining plate (4), or retaining plate
(5) with bearing cup replacer and a soft plastic hammer.
23. Install new encased oil seal (6) in second intermediate bearing retaining plate (3). Apply a thin even film of sealing
compound (WP 0035 00, Item 12) or (WP 0035 00, Item 13) to clean mating surface of seal. Position seal with lip
toward bore. Use a flat block of wood and mallet and tap seal in place so that top surface is .09 to .15 inch below surface
of retaining plate.
NOTE
Install bearing retaining plate with oil hole up. Most retaining plates have the word TOP
marked on metal near oil hole.
24. Determine thickness of new laminated shim (7) for bearing preload. Without shim and four new key washers (8)
installed, place output bearing retaining plate (4) on gearcase cover. Lube four cap screws (9) with engine oil. Secure
plate to cover with screws. Tighten screws (9) uniformly to 14–16 lb-in (1.5–1.8 N•m) torque. Use torque wrench
(WP 0033 00, Item 41). Rotate gear train by hand one revolution in each direction to check freedom of movement.
Recheck installation procedures if binding is detected.
