NOTE: Dealer warranty adjustment requests for oil

leak repairs, other repairs, or overhaul of the motor,

must include the model number of the motor and date

code. These are stamped into the mounting flange of

the motor housing at 1.

1. Thoroughly clean the outside of the motor hous-

ing before disassembly. Plug the ports to prevent

dirt and solvent from entering the motor housing.

2. To insure proper reassembly, mark the relation-

ship between the motor housing and backplate

with a marker or scribe, 2.

3. As the motor is being overhauled, lay the parts on

a clean wooden bench or heavy cardboard to

prevent damage to the machined surfaces.

4. Clamp the motor in a protected jaw vise at the

mounting flange. Remove the six cap screws, 1,

from the backplate assembly, 2, and lift the back-

plate straight up from the housing to prevent

damage to the shaft and bearings.

NOTE: The backplate assembly should pop up with

the removal of the six cap screws. If the plate does

not pop up, use a plastic mallet and tap on the back-

plate to remove.

IMPORTANT: The motor housing is aluminum and

can be easily damaged. Do not use sharp objects to

pry the backplate from the housing or damage to the

machined surfaces may occur.

5. Remove valve plate, 1, and O ring, 2, from the

backplate, 3. Note the position of the valve plate

for reassembly.
