holding the motor fan cover (FC). Turn the fan by
hand until the roller (102) stops at the bottom of
the pump housing (1) in the 6 o’clock position.

NOTE:
Low RPM pumps and high ratio
gearboxes may require many turns of the motor
fan to move the roller to the 6 o’clock position.
2. Remove the four screws (115) from the barbed
tting (105) on the inlet and outlet ports of the
pump.
3. Gently pull the barbed ttings (105) away from
the pump housing (1) so the hose extends about
2–3 in. (51–76 mm) out of the pump.
4. If possible, ensure that the hose clamps (104)
are positioned with the clamp portion at the top.
Cut through the clamp with a hack saw or rotary
tool. Be careful not to damage the hose (103) or
the pump housing (1).

the 6 o’clock position.

above.
9. Turn the motor by hand until the roller (102) is not
compressing the hose (103). This will be near
the 9 o’clock or 3 o’clock position.
