Replacing adapter and pump
assembly
To install a new filter, place a 5/8" socket over the fil-
ter and gently tap it down using a hammer.
Removing the electric motor
Remove the two studs (1) using an 8 mm socket (see
exploded view on page 155). Lift the motor off the
adapter assembly. Be sure the coupling (3) is posi-
tioned on the pump shaft with the wide groove up. See
exploded view, pos (3), on page 155.
Installing the electric motor
Apply water resistant grease to the coupling (3, fig.
above). Be sure that coupling is installed correctly. In-
spect the O-ring and replace if necessary (see explod-
ed view, pos (4), on page 155). Place the O-ring on
the motor. Install the motor on the adapter assembly,
ensuring the drive shaft engages the coupling. Tighten
the two studs.
The adapter and pump assembly contain no servicea-
ble parts and are replaced as a complete unit.
Remove the oil reservoir, motor and coupling.
Remove the valve assemblies using a 7/16" wrench.
The original factory fitted valves cannot be
installed in a new adapter/pump assembly.
Install new replacement valve assemblies, from the
factory, on the new adapter/pump assembly. See
Relief valve assemblies.
Install the oil reservoir.
Apply water resistant grease to the pump shaft and in-
stall coupling on the shaft. (Be sure the wide groove is
facing the motor.) Inspect the O-ring. Replace, if nec-
essary (4). Tighten using a 8 mm wrench.
NOTE! The electric motor does not need to be re-
moved to replace the thermal, high and low pressure
relief valve assemblies.
