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
indicates the direction in which the
exten•
sion shaft must be fully rotated to be in
volume position. Turn opposite way to be
in pressure position. Pump mode should
also be in volume position to ensure that
extension shaft and groove pin from
transfer valve ball will properly align when
reinstalling actuator to pump. Use
align•
ment marks as shown on attached page,
“Bottom View of Transfer Valve Ball in
Volume
Position.”
NOTE: The gear case shaft must be
used to turn the extension shaft.
