Coupler Removal (Fig. 16)
NOTE: The hydraulic pump assembly needs to be re-
moved from engine before coupler can be removed.
1. If engine is in machine, remove hydraulic pump as-
sembly (see Piston (Traction) Pump in Chapter 5 − Hy-
draulic System in this manual).
2. Remove flywheel plate and spring coupler from en-
gine.
Coupler Installation (Fig. 16)
1. Position spring coupler to engine flywheel and align
mounting holes. Make sure that coupling hub is toward
pump (away from engine flywheel) (Fig. 17).
IMPORTANT: The patch lock feature of the cap
screws used in this procedure suggest replacing
the screws after disassembly. An alternative would
be to apply Loctite #242 (or equivalent) to the
threads of the original cap screws during assembly.
2. Secure coupler to flywheel with cap screws (item 4)
and hardened washers. Tighten cap screws in a cross-
ing pattern from 17 to 21 ft−lb (23 to 28 N−m).
3. Position flywheel plate to engine. Make sure that
boss on plate is orientated down. Secure flywheel plate
with cap screws (item 5) and hardened washers in a
crossing pattern.
4. If engine is in machine, install hydraulic pump as-
sembly (see Piston (Traction) Pump in Chapter 5 − Hy-
draulic System in this manual).
