Components:
2. Access to Crankshaft Pulley. The Factory
Crankshaft Pulley will not need to be removed. The
Pulley Adapter will be bolted to the Factory Crank-

3. Install Pulley Adapter. The Pulley adapter
to be used is a round plate with 4 threaded

this pulley adapter will not have a center hole in
it (See Figure 4). The Non-treaded holes are

Do not use longer bolts to mount Pulley Adapter
to Pulley than is supplied with mounting kit.

two piece Assembly, an inner and outer shaft
assembly (See Figure 5). The Shaft End has a
four bolt flange yokes on it that connect to the
Crankshaft Pulley Adapter. The Tube end has a
splined clamp yoke on it that connects to the
Pump. This Drive Shaft connects to the Pulley
Adapter. Note that the Universals of the Driveshaft
are in time. When installed in tractor they should be
