Differential And Housing Disassembly - Toro Groundsmaster 220-D Service Manual

13. Assemble the bearing retainer bolts to the axle
housing. Apply a 0.625 in. (16 mm) bead of gasket
material to flange on end of axle housing, then install
the axle shaft assembly into the axle housing. Be careful
not to damage the oil seal and bearing. Line up the
holes of the brake assembly and oil seal. Push the axle
shaft as far as possible into the axle housing (Fig. 17).
Wheel end gasket material: P/N 92-8775 Liquid Gasket Kit
Make sure surface
is flat. File off any
high spots.
14. Start the nuts by hand. Tighten the nuts so the
bearing assembly is drawn evenly into the axle housing
(Fig. 18). NOTE: It is recommended that you replace
hex head screws and flange nuts with socket head
screws, washers and nuts (Fig. 18). If installing socket
head screws, tighten the nuts to a torque of 16 - 20 ft.-lb.
(2 - 3 Kgm). If reinstalling hex head screws, tighten the
nuts to a torque of 37 - 45 ft.-lb. (5 - 6 Kgm).
IMPORTANT: Hold the socket head screw or hex
head screw when tightening the nut to prevent the
head from turning into the tube radius.

Differential and Housing Disassembly

1. Remove the right and left-hand axle assemblies. (See
Axle Shaft Disassembly and Wheel Bearing Service in
this section of the book.)
Remove the eight (8) housing cap screws and separate
the upper and lower axle housings (Fig. 19). Clean the
gasket material from the mating surfaces before reas­
sembly.
NOTE: A complete Upper Housing Assembly for Dif­
ferential repairs is available. Using this assembly
eliminates the need for "trial and error" shimming pro­
cedures to establish the correct contact pattern between
ring and pinion gears.
