Grease Reservoir Models
Refer to F
IG
. 11 for reference numbers used in the fol-
lowing instructions.
Disassembly
The disassembly procedure may be performed with the
reservoir mounted on the pump assembly. However,
some mounting locations are too restrictive to provide
access to all components.
If installation requires dismounting of the reservoir, drain
the reservoir of lubricant before removing the attaching
hardware. This reduces the weight of the reservoir and
reduces the chance of spillage.
1. Follow Prepare for Maintenance , page 16.
2. Slowly open the reservoir drain (E), F
IG
. 1, page 6,
and allow the lubricant to flow into a container.
Drain all lubricant before removing the attaching hard-
ware to reduce the weight of the reservoir and to reduce
the chance of spillage.
3. Properly dispose of emptied grease adhering to all
applicable safety regulations and municipality
codes.
4. Remove the fill stud (13), if necessary (F
IG
. 11).
5. Remove hex nuts (1) and lock washers (5) from the
tie rods (3) (F
IG
. 11).
6. Remove tie rods (3) from reservoir cap (9) (F
IG
. 11).
7. Lift the reservoir (11) from the pump, keeping the
reservoir cap (9) in position on top of the tube (F
IG
.
11).
8. Slide the reservoir (11) away from the reservoir cap
(9) until it is free from the follower cups (15 and 17)
(F
IG
. 11).
9. Remove the gasket (8) from the pump (F
IG
. 11).
NOTE: Further disassembly is only possible at the
factory. If damage is apparent on the follower cups
(15 and 17), cable assembly (19), spring (10) or res-
ervoir cap (9) the unit cannot be serviced and the
reservoir assembly must be replaced.

cause serious injury. Never remove retaining ring (4)
or cable assembly (19).
