sure
to
note the location
of
the washers
between the

must
be installed at the
correct
location
to
give the
pump
and engine
the correct
alignment.
Remove the bolts from the rear hydrostatic pump mount.
Move the pump forward and
lift it up to remove it from the
loader

shims removed.
Lower the pump
assembly into position on the
transmission case and guide the
spline pump drive shaft

coupler yoke into engagement.
Install the bolts in the front and rear pump mounts. Fasten
the pump assembly to the rear mount.
Use key stock against the spider on the drive
coupler to
check alignment
[C].
Loosen the engine mounts if necessary to align the drive
coupler.
If
the height alignment is not correct, add
or
subtract half
thickness washers at the rear pump mount
[0]
.
NOTE: Measure from engine
mounting
plate
to
center
of
pump shaft. Also measure engine
distance
to
center
of
the flywheel, the
