5. Apply a generous amount of antiseize lubricant to
splines of transmission input shaft and flywheel coupler.
6. Place two (2) dowel pins in flywheel housing.
IMPORTANT: Make sure to not damage the trans-
mission, flywheel housing, hydraulic lines, electri-
cal harness or other parts while installing
transmission.
CAUTION
Support transmission assembly when installing
it to the flywheel housing to prevent it from fal-
ling and causing personal injury.
7. Lower transmission into machine. Align transmis-
sion input shaft with flywheel coupler and slide transmis-
sion to flywheel housing. Support transmission to
prevent it from shifting.
8. Secure transmission to the flywheel housing with
seven (7) cap screws and lock washers. Make sure that
shorter cap screw is properly positioned. Torque cap
screws 400 in–lb (45 N–m).
9. Install hydraulic tank to machine (see Hydraulic Tank
Installation in this section).
10.On both sides of machine, secure the pump control
rod to the traction control hub with cap screw and lock
nut (Fig. 36). Note that cap screw is installed from the
outside toward the center of the machine.
11. Remove plugs that were installed to hydraulic hoses
and fittings during the removal procedure.
12.Using labels placed during the removal process,
properly connect hydraulic hoses to transmission, gear
pump and hydraulic tank fittings (see Hydraulic Hose
and Tube Installation in the General Information section
of this chapter).
13.Lubricate gasket of new oil filter and install filter on
transmission.
14.Make sure that drain plugs are properly installed in
hydraulic tank and transmission. Fill hydraulic tank with
new hydraulic fluid.
15.Install operator seat and seat base (see Operator
Seat Installation in the Service and Repair section of
Chapter 6 – Chassis).
16.Plug wire harness electrical connectors to solenoid
valve coil and seat switch. Secure harness to frame.
17.Check parking brake and brake switch operation.
18.Adjust traction drive for neutral.
