FLUID MANIFOLD SERVICE AND REPAIR
REPACKING FLUID MANIFOLD (CON'T)
21. Insert a pair of needle nose pliers into the slots on the top of the piston rod. Pry up on the Piston Rod and turn it to
align the slots front to back.
22. Use a 1" open end or an adjustable wrench to tighten the upper retainer (#6) in Diagram A firmly.
23. Slide the slots of the piston rod onto the connecting rod.
24. Gently turn the fan in either direction and it will draw the pump assembly up to the crank housing. Be careful to
make sure the alignment pins line up while seating the pump housing.
25. Attach the transducer to the back of the pump housing. Make sure the o-ring (#18) in Diagram C, is in place
before threading it in. Tighten it firmly with a 3/4" open end wrench, while holding the steel tubing with a pair of
pliers.
26. Use a 5/16" Socket Wrench to insert the two hex bolts into the bottom of the pump housing and tighten firmly.
27. Replace the Front Cover (#11) in Diagram B.
28. Replace the Motor Cover and tighten the three screws (#1) snug.
29. Re-attach the suction assembly. Make sure to apply some packing grease to the two o-rings (#4) in Diagram E
before inserting the elbow into the intake valve assembly. Push the elbow straight in until it stops. Thread the nut
(#1) in Diagram E back onto the intake valve assembly snugly, but hand-tight.
REPLACING THE PRIME / SPRAY VALVE
1.
Using a 3/32" punch, knock out the pin (#29) from the black handle (#28) in Diagram A.
2.
Remove the black handle and cam exposing the prime/spray valve (#27) in Diagram A.
3.
Using a 3/4" open end or adjustable wrench, remove the prime/spray valve and inspect. Replace if worn or
leaking.
REPLACING THE MANIFOLD FILTER
1.
Remove the filter housing (#1) in Diagram A from the pump housing. New pumps from the factory will be tight and
you will need to use an adjustable wrench to loosen.
2.
Remove the filter (#3) and the filter core (#4) in Diagram A. Clean both components and if the filter is damaged or
worn, replace.
3.
When screwing the filter housing back in, make sure it is snug but hand-tight.
