10.Remove oil filter from transmission. Discard filter. If
necessary, remove gear pump from transmission (see
Gear Pump Removal in this section).
NOTE: Two (2) 8 mm eyebolts can be installed into
threaded bosses in top of transmission to allow use of
a lift or hoist to remove transmission (Fig. 37).
CAUTION
Support transmission assembly when removing
it from the flywheel housing to prevent it from fal-
ling and causing personal injury.
11. Remove seven (7) cap screws and lock washers that
secure the transmission to the flywheel housing. Note
location of the shorter cap screw for assembly pur-
poses.
IMPORTANT: Make sure to not damage the trans-
mission, flywheel housing, hydraulic lines, electri-
cal harness or other parts while removing
transmission.
12.Move transmission assembly toward the front of the
machine and away from the flywheel housing and cou-
pler on engine flywheel. Lift transmission from machine.
13.Locate and note location of two (2) dowel pins from
transmission and flywheel housing.
14.On both sides of transmission, remove retaining ring
that secures pump control rod end onto transmission
control arm (Fig. 36). Slide control rod from control arm.
15.If hydraulic fittings are to be removed from transmis-
sion, mark fitting orientation to allow correct assembly.
Remove hydraulic fittings from transmission as needed.
Discard fitting O–rings.
16.Inspect flywheel housing and coupler on engine fly-
wheel for evidence of wear or damage.
Transmission Installation (Fig. 35)
1. Make sure that flywheel coupler and flywheel hous-
ing are secure on engine (see Engine Installation in the
Service and Repairs section of Chapter 3 – Kubota Die-
sel Engine).
2. If hydraulic fittings were removed from transmission,
lubricate and install new O–rings to fittings. Install fit-
tings into transmission ports (see Hydraulic Fitting
Installation in the General Information section of this
chapter). Tighten fittings to torque values identified in
Figure 38).
3. If gear pump was removed from transmission, install
gear pump (see Gear Pump Installation in this section).
4. Slide both pump control rods onto transmission con-
trol arms and secure with retaining rings (Fig. 36).
