BASIC PUMP ASSEMBLY
1. Lubricate secondary seal (2) with
petroleum jelly and place in position
against shaft end of body (1). Use a small
hardwood block to drive the seal evenly
into body. Installation is complete when
seal face is flush with front of the body.
NOTE:
DO NOT
drive seal past flush
as it can block body drain
opening.
2. Lubricate primary seal (3) with petroleum
jelly and place in position inside of body (1)
and press in place with shaft seal driver.
3. Install washer (4) into body (1).
4. If required, press bearing (6) on shaft (5) and secure with retaining ring (7). Use an arbor press for
this operation and apply force to inner race area.
5. Check splined end of shaft to make certain it is free from nicks and burrs. A small nick or burr can
damage shaft seal during installation. Coat splined portion of shaft with hydraulic oil. Carefully install
the shaft group, (items 5, 6, and 7), through seals (2 and 3) and into body (1). Spread Spirolox ring
(8) and feed it into groove behind bearing. This will secure the shaft group within body (1).
6. Install sealing ring (11) into body (1).
7. If center cartridge kit (40) is replaced with
a new kit, install kit into inlet body (1). If
cartridge kits requires assembly, assemble
in reverse order of disassembly. See
"Cartridge Assembly." During assembly,
note the following precautions:
A. Make sure the arrows on rotor (17)
and cam ring (16) are in same
direction of pump rotation.
B. Make certain that sharp edges of
vane (18) lead in direction of rotation.
C. Make sure O-ring (10) and back-up
ring (9) are assembled correctly.
Apply a small amount of hydraulic oil
to screws (21) and thread screws
into cartridge (40). Install cartridge kit
(40) into body (1).
