Adjusting Axial Clearance on Tapered Roller Bearing
NOTE:
If the following parts have been replaced,
readjust the axial clearance or tapered roller
bearing (22) selecting retaining rings (20)
having a suitable thickness: Hub (1), Spindle
(2), Hold flange (3), RV gear assembly, and
snap rings (20). If you assemble without
checking, it could cause the can motor to
operate poorly or break down prematurely.
• If not replacing the parts listed above, retaining ring
adjustment is unnecessary, and main assembly is
carried out from "Install Retaining Rings" on
page 1-57 as is.
• Shaft direction clearance adjustment method of the
tapered roller bearing is as fellows.
1. Apply holder (IV) to the outer ring of the tapered roller
bearing (22) on the crank shaft (9), and lightly hammer the
holder.
NOTE: Hammering makes insertion of the RV gear
assembly into spindle (2) easier.
2. Fit the least thick the retaining rings (20) in the retaining
ring grooves in the spindle (2).
