Group 170 Preventive Maintenance
Lubrication
Make sure that grease fittings are cleaned off before fill-
ing grease. Dirt on the fitting that is not cleaned off is
pushed into the part with the new grease. Always fill
grease to the point where old grease and contaminants
are forced out from the part and only new grease comes
out. If grease cannot be filled so old grease is forced out
or if new grease exits without pushing old grease out,
note this on the form for repair. If a fitting does not ac-
cept lubrication due to damage or internal stoppage,
replace with a new fitting.
Do not heat the part for better grease application where
rubber or plastic parts are involved.
Remove excess grease from fittings, spring shackles and
other surfaces.
