23. If connecting rod is not in the down position plug unit in and cycle unit to get connecting rod into down
position.
24. With piston slots aligned slide pump/filter manifold onto connecting rod #56 Diagram "B". Push
pump/filter manifold towards crank housing # 53 to line up dowel pins then thread mounting bolts #25
through pump filter manifold and thread into crank housing #53. Tighten firmly with5/16" Hex wrench.
25. Reattach transducer #30 to the back of pump/filer manifold.
26. Reinstall crankshaft cover plate #55 with 4 screws #40. See diagram "B".
27. Reattach suction set.
28. Pour Trilube through slot in cover plate #55, diagram "B".
REPLACE BY-PASS VALVE
1. To replace the pressure relief valve #27 knock pin #29 through black handle #28.
2. Remove black plastic handle and cap with indexing pin which exposes pressure relief valve.
3. Using a 3/4" open end unthread by pressure relief valve. Inspect. Replace if worn.
REPLACE FILTER

2. Remove mounting screws # 25.
3. Remove 4 screws for crank housing cover plate # 55.
4. With a flat blade screwdriver pry pump/filter manifold downward till it clears locating pins and slide
forward but do not remove.
5. Remove 4 screws #40 and Control box cover plate #70.
6. Unplug transducer from circuit board. See diagram "B".
7. Guide transducer wire out of control box.
8. To replace guide replacement transducer through grommet #91 and reconnect to circuit board.
9. Thread transducer into pump/filter housing.
10. Replacement of transducer requires no calibration of pressure control. To ensure new transducer
