13. GREASE SEAL
If the grease seal (104) has been removed from the bearing
cover (27), it must be replaced prior to attaching the cover to
the pump. Apply a small amount of grease to the outside
diameter of the grease seal, and push it into the cavity of the
bearing cover so that the lip of the seal will face inward
(towards the pump) when the cover is attached.
14. BEARING COVER
Place the bearing preload wave spring (24C) against the
outer bearing race. Install a bearing cover O-ring (26) into the
groove in the bearing cover (27) and slide the cover over the
shaft with the V-notch down. Install and tighten the bearing
cover capscrews (28).
CAUTION: The pump MUST NOT be operated without the
bearing covers bolted into place.
15. SHAFT PROTECTOR
Install and tighten the threaded shaft protector (185) into the
bearing cover (27) on the non-driven end of the pump.
16. RELIEF VALVE ASSEMBLY (if equipped)
a. Insert the valve (9) into the relief valve body (6) with
the fluted end inward.
b. Install the relief valve spring (8), spring guide (7) and
guide rod (45) against the valve.
c. Attach a new relief valve gasket (10) and the valve
cover (4) on the cylinder.
d. Screw the relief valve adjusting screw (2) into the
valve cover until it makes contact with the spring guide
(7).
e. Install the relief valve cap (1) and gasket (88) after the
relief valve has been precisely adjusted.
The relief valve setting MUST be tested and adjusted
more precisely before putting the pump into service.
Refer to "Relief Valve Setting and Adjustment"
