12. Insert the Bellville preload washer (529) into the outboard end of the bearing cartridge
housing (228) so it is in contact with the outboard taper roller bearing (410). Grease shield
346A shown above is for grease lube only.
13. Insert the outboard labyrinth seal (332A) into the outboard bearing cover (109).
14. Lubricate the outboard bearing cover o-ring (412) and insert into the outboard bearing
cover (109).
15. Slide the outboard bearing cover (with seal and o-ring attached) into the bearing cartridge
housing (228) carefully to avoid o-ring damage.
16. Hand tighten the outboard bearing cover assembly to the bearing cartridge housing (228)
using the hex head cap screws (370N) until the shaft becomes very difficult to rotate by
hand. There will be virtually no end play.
17. At the point where the shaft is very difficult to rotate by hand, measure gap between face of
bearing end cover (109) and the face of the frame with feeler gages.
18. Select and measure shim pack such that the thickness of the shims are equal to the gap
measured in (17) above plus 1.02 mm | 0.040" added shim. Be sure to measure in several
places to assure a uniform end cover gap is being measured.
19. Remove the end cover (109) and add the shim pack (390C) noted above to the assembly.
20. Secure the outboard bearing cover assembly to the bearing cartridge housing (228) using
the hex head cap screws (370N).
WARNING:
Failure to provide the proper shimming to adequately preload the taper roller bearings, will
result in high bearing temperature.
Rotate shaft by hand to ensure it rotates smoothly and there is no rubbing which could lead to
excess heat generation, sparks and premature failure.
