MAINTENANCE
13. Place small amount of Loctite # 220 onto seal mounting
capscrews (153J). Install into corresponding threaded
holes on seal sleeve. Torque capscrews to 20 inlbf
(2.25 Nm).
14. Lightly lubricate inner O-ring (153L) on carbon rotating
face using bearing grease identified in this manual. Take
care to keep seal face free from grease.
NOTICE
:
Use ONLY recommended grease.
Using petroleum
based grease or oil to lubricate seal O-rings WILL cause
seal O-ring damage and subsequent product leakage.
15. Install carbon rotating face and O-ring over shaft while
aligning drive notches with drive pins in seal rotating
assembly. (see figure 8)
16. Install a new stationary O-ring (153D) in the stationary
seat (153B). Clean the polished face with a clean tissue
and alcohol. Push the seat fully into the seal recess with
the polished face outward.
17. Apply small amount of Loctite #220 to seal retaining
screws. Install seal retaining screws and washers
(153Q, 153R).
18. If removed, press the grease seal(104A) into the grease
seal carrier (104b) with the lips facing toward the
bearing. Place the grease seal carrier (104B) with new
O-ring (104C) into the hub (20C).
19. Hand pack the ball bearing (24) with grease. Refer to
the "Lubrication" section for the recommended grease.
20. Install the bearing into the recess of the hub (20C).
21. Temporarily attach the bearing cover (27) and gasket
(26) to hub and hand tighten capscrews (28).
22. Install new hub O-ring (72B) and carefully install the hub
assembly (20C) on head. Install and tighten hub
capscrews (21A) torquing as indicated in the “Torque
Table”.
23. Remove the bearing cover and loosely install the bearing
locknut and lockwasher (24A, 24B). Snug the locknut on
the outboard head to help square the rotor with the head.
DO NOT overtighten the nut.
24. Set the pump upright.
25. Remove the outboard head and disc temporarily
attached earlier.
26. Complete assembly on the
OUTBOARD
side of the
pump as instructed for the inboard side in steps 10-24,
leaving the head capscrews loosely tightened.
27. Loosen the bearing locknut on the outboard head and
the rotate the shaft to test for binding or tight spots. If the
rotor does not turn freely, lightly tap the rims of the heads
with a soft faced mallet until the correct position is found.
Retighten all head capscrews, torquing to the
specifications indicated in the “Torque Table”.
