(44) adapter, unthread and remove (44) adapter, releasing (43) ball
and (42) ball stop.
PUMP REASSEMBLY
NOTE: Thoroughly clean and lubricate all seals and bores with
Shell Gadus S2 U1000 upon assembly. Replace all soft parts with
new ones included in the repair kit. Note: Refer to the illustration
(figure2, page 3) for "U" cup lip seal direction.
1. Assemble (42) ball stop and (43) ball into (41) plunger, securing with
(44) adapter. NOTE: Torque (44) adapter to 50 - 70 ft lbs (67.8 - 94.9

TROUBLE SHOOTING

If the pump will not cycle or will not deliver material.
Be certain to check for non-pump problems including kinked, restric-

the pump system and clean out any obstructions in the inlet/outlet
material lines.
Check all seals, including track gaskets.
Check direction of "U" cup lips.
