5. If replacement of the mount bracket is required,
loosen and remove the (2) Phillips head screws
from the plastic mount bracket. Replace bracket and
torque the (2) Phillips head screws to 20 in. lb. (2.2
Nm).
NOTE: Do not over-torque screws. This can cause
in damage to the casting or screw.
6. If required, slide the shaft assembly from the casting
and replace any damaged or worn parts.
7. Prior to reassembly of the shaft assembly into the
casting, lubricate the shaft and O-ring with a light
grease. This will reduce wear on parts during use
and make assembly easier.

the toggle switch is engaged. Slight twisting of the
shaft forks may be necessary to get proper align-
ment.

the switch, if the wires are backwards then the vane
pump will pump in the wrong direction.

and tighten to 22 in. lb. (2.5 Nm).
