HYDRAULIC COMPONENTS
Refer to Figures 15-24.
DISASSEMBLY
(Pump Block)
1. Remove the brake assembly and bypass
arm. See page 16.
2. Remove the control arm and friction pack.
See page 17.
3. Drain the oil from the transaxle. See page
10.
4. Remove the side housing. See page 19.
5. Remove the seals in the side housing. See
page 18.
6. Remove the axle shaft, differential and re-
duction gears. Refer to page 20.
7. Remove the motor shaft and bypass rod.
See page 21.
8. Remove the input shaft. See page 22.
9.
(See Fig. 15)
Remove the swashplate (4)
and pump cylinder block (5) as one assem-
bly. NOTE:
Removal will be aided by apply-
ing a small amount of pressure on the trun-
nion mounted swashplate towards the cen-
ter section. Also note that the control arm
(18, Page 32) may be loosely assembled at
this point to assist in swashplate removal.
While gently removing the swashplate and
block assembly, keep the block face flush
with the center section
to
minimize damage
to the running surface
.
10.
(See Fig. 16)
Disassemble the pump cylin-
der block (5) from the swashplate (4).
11.
(See Fig. 17)
Check each piston for proper
operation by pressing the pistons in and
releasing them in the block bore. Disas-
semble the pump cylinder block. Check for
piston/block wear in the cylinder bore. In-
spect the pistons (1), piston springs (2) and
piston seats (3) for excessive wear or dam-
age. NOTE: Piston seats may be held in
place in the piston by residual oil.
12. Reassemble the pistons, springs and seats
into the cylinder block and set aside.
13.
(See Fig. 18)
Remove the thrust bearing
assembly (19) from the swashplate (4).
(Center Section/Filter)
14.
(See Fig. 19)
Remove the center section
mounting screws (44). NOTE: The center
section is under motor block piston spring
pressure. These screws are factory in-
stalled to 700 in. lbs. (80 Nm) and use an
anaerobic thread adhesive. A breaker bar
will be required at this step. Clean the inter-
nal threads of the mounting holes with
compressed air.
15. Remove the center section and filter as-
sembly (124, Fig. 20).
16.
(See Fig. 21)
Remove the filter (45) from
the filter base (46) by snipping the four
posts with side cutters or applicable tool.
NOTE: This filter cannot be reused.
17. Remove and inspect the deflector (107),
bypass actuator (47) and bypass spring
(43).
18. Note the location of both check plugs (23 &
75) before removal for correct placement
during reassembly. Remove and inspect
the check plug assemblies (23) for debris
or damage.
19. Remove the filter base (46) and discard it.
NOTE: The filter base is included in the fil-
ter kit to be installed during reassembly of
the unit.
(Motor Block)
20.
(See Fig. 22)
Remove the motor cylinder
block assembly (5) from the housing (1).
21. Disassemble the motor cylinder block as-
sembly (5). Check each piston for proper
operation by pressing the pistons in and
releasing them in the block bore. Disas-
semble the motor cylinder block. Check for
piston/block wear in the cylinder bore. In-
spect the pistons, piston springs and piston
