Vehicle must be removed from blocks and jacks for knuckle pin lubrication to assure purging of grease. Force grease
through the top and bottom lube fittings until grease purges through the shim gap when greasing the top and through the
thrust bearing seal lip when greasing the bottom.
It is not necessary to exceed 4,000 psi pump pressure. However, our experience indicates that the base distribution of
new lubricant and the best purging of old lubricant is obtained when approximately 4,000 psi pressure is applied at the
grease gun nozzle. Thus, using a 40 to 1 booster, air should be limited to 100 psi; using a 50 to 1 booster, air should be
limited to 80 psi. Higher pressures are not recommended.
The particular grease used should meet Rockwell-Standard Specification 0-617-A or optional 0-617-B in Rockwell-
Standard's Field Maintenance Manual No. 1, Lubrication". Recommended lube intervals for the sealed knuckle pin is
