7. When installing the rear cover, note the bosses on

the back side of the cover. They must go behind the

notch in the chassis to secure the cover. The top of

the cover is retained with screws (Fig. 113).

5. Make sure the stepped washer is properly seated

in the wheel cover. The best way is to assemble the

wheel, wheel cover, and wheel bolt, then put them all

on the mower together.

6. Do not use an impact wrench on the crankshaft belt

guide screws. Over-tightening can cause the belt

guide to deform and cause the belt not to declutch

properly. Tighten rmly with a ratchet.

4. The wheel pinion is marked with an R and L for right

and left. Identify right and left from the operator’s

position (Fig. 112). On the right side, the R should

face outward. The letter L should face outward on

the left side. If the wheel pinions are reversed, the

wheels will not drive.
