by removing spirol pin, 1/8 x 3/4, from
U-joint. Then slide entire assembly out
from gear motor shaft.

by removing socket head screws, 5/16-18
x 5/8 and (3) lock washers, 5/16 and (3)
lock washers, 5/16.
4. Extension shaft may come loose from

6. When reinstalling transfer valve actuator,
make sure extension shaft is turned to the
volume position. To find out if actuator is in
the volume position, check under
mounting bracket for a stamped arrow with
the letter
“V” for volume. The arrow indi-
cates the direction in which the extension
shaft must be fully rotated to be in volume
position. Turn opposite way to be in
pres•
sure position. Pump mode should also be
in volume position to ensure that
exten•
sion shaft and groove pin from transfer
valve ball will properly align when
reinstal•
ling actuator to pump. Use alignment
marks as shown on attached page,
“Bot
tom View of Transfer Valve Ball in Volume
Position.”
NOTE: The gear motor shaft must be
used to turn the extension shaft.
