Oil Fill Options Transfer Case Oil Levels
WARNING
•
Use only the type of lubricant specified by the
equipment manufacturer. Do not use or mix
different types of lubricant. The wrong
lubricant can cause damage, incorrect
operation and serious personal injury.
•
Do not reuse lubricant. Used lubricant can be
contaminated and can cause damage, incorrect
operation and serious personal injury.
NOTE:
•
Prior to adding the fill pipe type of oil fill option,
only a single plug location was available at
approximately the 5 pint level.
•
Various oil levels are put onto transfer cases due
to the optional constructions, add on equipment
and special operating circumstances. The pints
assigned are the approximate amount of oil
required to fill the transfer case to the appropriate
level depending upon the transfer case
construction and orientation within the vehicle.
The actual amount of oil may be substantially
different from that shown in Figure 36.
•
For specific duty transfer cases, Rockwell may
vary oil level recommendations which may not
agree with the unit’s oil stand pipe level as
originally provided by Rockwell.
The basic rules for establishing the correct transfer
case oil level are as follows:
•
For a T-2111 transfer case, the base oil level should
be 3 pints (1.42L).
•
For each declutch, PTO and oil pump that supplies oil
only to the top of the transfer case, add 1 pint (0.47L).
•
A proportional differential unit should have a 5 pint
(2.4L) fill level, although the transfer case will require
substantially more oil.
•
For applications over 2500 RPM, the proportional
differential unit may require less lube.
•
If an exterior oil cooler is used, add 2 pints (0.94L).
