Important: When reusing components, carefully inspect the parts. Ensure that key dimensions are within
acceptable limits. Visually inspect the parts for pitting, worn vanes, damaged threads, damaged gasket
faces, excessive corrosion, deformation, etc. Discard any component that is not within acceptable
standards. Ensure that the components are clean before installing.
Mechanical Rotary Seal:
The mechanical rotary seal requires careful
inspection. The seal should be discarded if there are signs of leaks or if the
internal drive bushing is excessively deformed. The drive bushing must be
free to rotate without contact with the brass housing. If there is contact
between the drive bushing and the housing, the seal must be discarded.
1. Slide bearing retaining ring #16 on shaft #14 with plain face toward coupling collar.
2. Press bearing #17 on shaft using tool 600052.
3. Carefully press rotary seal #18 in pump body #3 using pressing sleeve tool 700531.
4. Apply a small amount of dish soap on mechanical rotary seal O-ring to facilitate installation of pump
shaft. Carefully pass end of shaft assembly through mechanical rotary seal bore. Make sure that flat
sections of shaft line up with rotary seal drive bushing flat sections. Gently press down shaft until ball
bearing rests firmly against shoulder in pump body. To verify that shaft has been properly installed,
slowly rotate shaft by hand; rotary seal drive bushing should rotate with shaft.
5. Attach retaining ring #16 to pump body with six screws #15 to a torque value of 22-25 in-lbs / 2.5-2.8
Nm . Tighten evenly.
6. A small amount of marine grease can be applied onto shaft to facilitate future disassembly.
7. Slide impeller #19 onto shaft, and engage with mechanical rotary seal.
8. Smear the O-rings with a suitable lubricant to facilitate assembly.
9. Place O-ring #25 in groove of distributor #20.
10. With open end of pump body in vertical position, carefully lower distributor #20 until it rests on bottom
of body. Ensure that O-ring did not fall out of position during installation of distributor.
11. Slide impeller #19 into position, aligning with previous impeller.
12. Place O-ring #26 in groove of distributor #21.

NOTE: The sealed bearing eliminates pump failure dangers related to improper
greasing by completely removing the need to grease the pump end bearing.
