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, support engine from below to prevent it from shifting while removing hydraulic pump assembly (see Piston (Traction) Pump Removal in the Service and Repairs section of Chapter 4 -- Hydraulic System), transport cylinder assembly, flywheel plate, engine mounts and spring coupler.

2.Remove flywheel plate and spring coupler from en- gine using Figure 16 as a guide.

Coupler Installation (Fig. 16)

1.Position spring coupler to engine flywheel and align mounting holes. Make sure that coupler hub is away from engine flywheel (Fig. 17).

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.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 hydraulic pump as- sembly (see Piston (Traction) Pump Installation in the Service and Repairs section of Chapter 4 -- Hydraulic System).
