Installation
1. To install the transaxle, perform Transaxle Removal
procedure in reverse order noting the following:
IMPORTANT: Workman 3100 (air cooled, gasoline
engine) vehicles require application of silicone seal-
ant to mating surface of bell housing and clutch
adapter plate on engine. This will prevent dirt and
debris from getting into bell housing and damaging
clutch or release bearing.
A. When installing driveshafts to transaxle, align
mounting holes in driveshaft with relief in transaxle
shaft. Install cap screws, hardened washers, and
flange nuts to secure driveshaft to transaxle shaft.
Torque fasteners from 35 to 42 ft–lb (47 to 57 N–m).
B. Apply Loctite #242 (or equivalent) to the threads
of cap screws used to secure the control cable sup-
port bracket to the transaxle.
C. Before installing two shift levers and shift arm
onto transaxle shafts, thoroughly clean shafts and
apply Loctite #680 to threads and tapers of shafts.
Secure by torquing nut from 200 to 280 in–lb (22.6 to
31.6 N–m) while holding lever to prevent torque
transfer into transaxle (Fig. 19).
2. Install a new hydraulic oil filter and fill transaxle with
the correct oil (see Operator’s Manual). Check for oil
leaks and repair as necessary.
3. Adjust clutch pedal, shift cables, high–low cable and
differential lock cable (see Operator’s Manual).
4. If equipped with PTO, adjust PTO cable (see PTO
