16. Put the ring gear onto the differential case and start
the new capscrews into the gear with your fingers.
Tighten the screws, alternating back and forth across
the gear to allow the gear to be pulled evenly into place.
Tighten the cap screws to a torque of 45 - 65 ft-lb (6.2 -
9.0 KgM) (Fig. 50).
17. When installing new differential bearings, reuse the
original shims or use new shims of the same thickness.
Press the bearing onto the differential case. If a new
differential case is being installed, start with a .020 inch
pack of shims under each differential bearing. Shims are
available in .003, .005, .010, and .030 inch sizes
(Fig. 51).
18. Assemble new differential bearing cups to differen-
tial bearing cones. Seat differential assembly with drive
gear on proper side of carrier into carrier bearing cra-
dles.
NOTE: Groundsmaster 300 Series (S/N 90001 & up)
require that the ring gear teeth face toward the spur gear
cover.
The bearing cradles are designed to apply a slight
preload to the bearings. It is important to push both of
the bearing assemblies simultaneously into their
saddles.
Bearing caps must be installed with indexing marks “P”
adjacent to indexing marks “P” in case. Install the bear-
ing caps into their original position as previously
marked. Tighten the cap screws to a torque of 30 - 45
ft-lb (4.1-6.2 KgM) (Fig. 52).
