Lubrication Procedures
Lubrication Procedures
Incompatibility is best determined in service or in service-
related tests; it is not predictable. Certain thickener combina-
tions often have been found unsatisfactory and are generally
so recognized. These would include lithium and sodium
greases and organo-clay and most soap greases. Contact
your local lubricant supplier for grease compatibility infor-
mation.
To help reduce the effects of incompatible greases, make sure
to thoroughly purge all four bearing seals on each universal
joint with the new grease. Purge seals until the fresh grease is
visible on the outside of all four bearing seals.
It is recommended that all purged grease be wiped clean to
prevent discharge into the general environment.
Intervals for Relubable Universal Joints
Lubrication intervals vary depending on the service require-
ments and operating conditions of the vehicle or machine.
Table F, below, shows the recommended universal joint lubri-
cation intervals for various types of service.
City is defined as all applications that require a minimum of
90% of operation within city limits.
On-highway is defined as all applications requiring less than
10% of operating time on gravel, dirt or unpaved roads.
Off-highway is defined as all applications requiring more than
10% of operating time on gravel, dirt or unpaved roads.
Linehaul is defined as 100% of operation time on smooth
concrete or asphalt.
*Relubrication intervals for off-highway and industrial use
vary depending on the application and operating conditions.
In general, to obtain maximum life, relubrication on industrial
applications should occur every 500 hours for normal service
and every 250 hours for continuous service or severe envi-
ronmental conditions.
Universal Joints Lubrication
1. Use the recommended lubricant to purge all four
seals of each universal joint. This flushes abrasive
contaminants from each bearing assembly and
assures proper filling of all four bearings.
Note: Make sure fresh grease is evident at all universal joint
bearing seals.
