Pump Reassembly
NOTE: The following instructions describe the proce-
dure to follow to reassemble a completely disassembled
LD grease pump. Depending on the repair/maintenance
procedure you are performing on the pump, it may not
be entirely disassembled. See the specific section(s)
related to your repair/replacement kit.
For all reassembly procedures:
• Clean all the parts carefully in a compatible solvent,
and inspect for wear or damage. Use all the repair
kit parts during reassembly, and replace other parts
as necessary.
• Check the all polished surfaces for scratches or
wear.
• Lubricate all parts with a light, water-resistant
grease.
1. Install new o-rings and seals in bottom cover (14)
and flange (22) as described in the Throat and Pis-
ton Seal Replacement Kit 24H854, page 11. Be
sure to apply a thin coat of water-resistant grease to
all o-rings and seals.
2. Align pilot valve (20) installed in bottom cover with
opening (a) in flange (22) as shown in Fig. 12. Com-
press the bottom cover (14) and flange (22)
together.
3. Install 3 screws (3) (Fig. 13). Tighten with a 5 mm
socket wrench and torque to 60-70 in lbs (6.8 – 7.9
N.m).
4. Apply a thin coat of grease round the top of the dis-
placement rod (50). Push the displacement rod
through the opening in the bottom cover and into the
flange assembly as shown in Fig. 14.
5. Install the air cylinder (21) over the bottom cover
(14). Place the top of the air cylinder down on a
clean hard surface. Use the palms of your hands to
press the bottom cover firmly into the air cylinder
(Fig. 15).
