Step 4
Completing the installation.
After applying some oil to the new adapter plate O-ring,
insert it into the pump head. Without touching the lapped
face, insert the new seat and oiled seat O-ring into the
adapter plate. Install the adapter plate in the pump head.
Install the shaft O-ring on the shaft.
C. Slide the bearing housing over the
shaft and install the bearing cap
using a criss-cross method on the
bolts and make sure the pump
shaft turns freely.
Step 5
Proper lubrication.
For proper lubrication, use MIL-G-10924C ball bearing
grease only. Each pump is equipped with a grease zerk and
relief fitting. Before greasing the bearing, the grease zerk and
relief fitting must be cleaned thoroughly. If any dirt is forced
through the grease zerk, early bearing failure will result.
Overgreasing will damage the pump bearings. To help
prevent overgreasing, use a hand operated grease gun.
Insert the grease slowly and stop as soon as the relief
fitting opens. Excessive grease may drip out of the relief
fitting for several hours after lubrication.
Step 6
Repressurize the system.
For best results slowly pressurize the pump with vapor
before introducing liquid to the pump. When liquid enters
a unpressurized pump-even slowly-it can sometimes
refrigerate enough to keep the O-rings/elastomers from
sealing properly and cause a leak.
Watch alignment C!
Vapor first, then liquid!
Do not overgrease!
NOTE: When lubricating truck pumps, grease the U-joints
and the spline of the drive shaft as well.
