Coupler Removal (Fig. 18)
NOTE: The hydraulic pump assembly needs to be re-
moved from engine before coupler can be removed.
1. If engine is in machine, support engine from below to
prevent it from shifting. Remove the following:
A. Remove hydraulic pump assembly from machine
(see Piston (Traction) Pump Removal in the Service
and Repairs section of Chapter 4 -- Hydraulic Sys-
tem).
B. Remove transport cylinder assembly from engine
mount. It is not necessary to remove the hydraulic
hose from the cylinder. Locate and remove cylinder
spacer from between transport cylinder and engine
mount.
2. Remove flywheel plate and spring coupler from en-
gine using Figure 18 as a guide.
Coupler Installation (Fig. 18)
1. Position spring coupler to engine flywheel and align
mounting holes. Make sure that coupling hub is away
from engine flywheel (Fig. 19).
2. Apply Loctite #242 (or equivalent) to threads of cap
screws (item 3). Secure coupler to flywheel with six (6)
cap screws and washers. Torque cap screws in a cross-
ing pattern from 29 to 33 ft- -lb (40 to 44 N- -m).
3. Apply Loctite #242 (or equivalent) to threads of cap
screws (items 5 and 7) used to secure flywheel plate to
engine. Position flywheel plate to engine and engine
mounts. Secure flywheel plate and mounts with cap
screws (items 5 and 7) and washers using a crossing
pattern tightening procedure. Torque cap screws in a
crossing pattern from 28 to 32 ft- -lb (38 to 43 N- -m).
4. If engine is in machine, install the following:
A. Install transport cylinder assembly to engine
mount. Make sure that cylinder spacer is placed be-
tween transport cylinder and engine mount. Check
transport cylinder adjustment (see Transport Cylin-
der in the Service and Repairs section of Chapter 4 --
Hydraulic System).
B. Install hydraulic pump assembly to machine (see
Piston (Traction) Pump Installation in the Service
and Repairs section of Chapter 4 -- Hydraulic Sys-
