(4) Place mounting flange assembly on a pair of parallel blocks, on an arbor press with bearing side up. Apply

a light coat of grease (item 11, Appendix C) on the outside diameter of the bearing. Making certain that

the bearing (40) is squarely started in the bore, proceed to press the bearing into the bore until it is flush

with the mounting flange assembly surface.

(5) Turn the flange over. Start the oil seal (39) into the bore making certain that it enters squarely. Note

should be taken at this time that the garter spring in the seal is facing in the direction of the bearing. Press

the seal into the bore to a depth of inch below the surface of the flange.

(6) Install two retaining rings (37) on piston (36). Be sure retaining rings do not overlap each other. Coat

sure shaft (33) has entered bearing (41) freely.

(8) Install washer (38) on shaft (33). Place the pump on a bench with the drive shaft facing upward. Be

certain that the woodruff key and any nuts and washers are not attached to the drive shaft at this time. At

this point check to see that washer (38) is in place. Next, insert the mounting flange assembly (31) and O-

ring gasket (32) over the drive shaft. Install lockwasher (30) and screw (19) and tighten.
