RPL20, RPL25 and RPL25SD Series
Permalube Procedures
The following procedures are for RPL20, RPL25 and RPL25SD
series Permalube drivelines. For RPL10, RPL14, RPL35 and
RPL35SD series Permalube drivelines, refer to those procedures at
the beginning and end of this section.
DANGER
Park the vehicle on a level surface. Block the wheels to prevent
the vehicle from moving. Support the vehicle with safety stands.
NEVER work under a vehicle supported only by jacks. Jacks can
slip and fall over. Failure to use a jack stand can result in serious
personal injury and damage to components.
DANGER
Only service a driveline when the engine is OFF. A rotating
driveline can cause serious personal injury.
WARNING
To prevent eye injury, always wear eye protection when
performing vehicle maintenance or service.
WARNING
Use a brass or synthetic mallet for assembly and disassembly
procedures. NEVER hit steel parts with a steel hammer. Pieces
of a part can break off. Serious personal injury and damage to
components can result.
WARNING
Only install the correct grade new bearing retainer bolts and
stamped strap bolts. Do not reuse these parts. If the bearing
retainer straps are damaged, install new retainers. Damaged and
reused parts can affect driveline operation, which can cause the
driveline to separate from the vehicle. Serious personal injury
and damage to components can result.
WARNING
A driveline assembly can weigh more than 100 pounds
(46 kilograms). Always use lifting devices and the correct
procedures when you handle drivelines to prevent serious
personal injury and damage to components.
