Refer to Figure 7-7:
1.
Assemble components for the unit specification to
the engine. Install muffler, air cleaner, oil drain valve,
and oil sender to the engine. Temporarily install the
engine pulley spacer, hydraulic drive pulley, and the

reinstalling the belts.
2.
Install engine spacer plate with the cut out to the
front of the engine and install the alignment studs on
two opposing corners of the engine though the

assembly into the frame. Align the clutch stop
rotation tabs to fit though the frame. Lower the
engine alignment studs into the main frame and
ensure that the engine is centered on the frame.
Refer to Figure 7-8:

Remove the alignment studs and secure the engine
assembly to the main frame with washers, spring
lock washers and bolts. Apply two drops of blue loc-
tite to the threads of each bolt and tighten until the
spring lock washer is fully compressed against the
washers, approximately 15-18 ft/lbs.
