GENERAL INFORMATION
POWER TRANSFER UNIT
The Power Transfer Unit (P.T.U.) is attached to a
modified automatic transaxle case where the right
half shaft extension housing would normally be
located. The Transfer Unit provides the power to the
rear wheels through a hypoid ring gear and pinion
set.
The Power Transfer Unit is sealed from the tran-
saxle and has its own oil sump. The Unit uses SAE
85W-90 gear lubricant and holds 1.15 liters (1.22
quarts).
The Power Transfer Unit fill plug is located on the
end cover (Fig. 1). Do not mistake the black plas-
tic inspection plug located on the P.T.U. case
for the fill plug.
Service of the Power Transfer Unit is limited to:
•
Seals
•
Gaskets
•
One ball bearing
•
Output flange
If the ring gear and pinion, any tapered roller
bearings, case, covers, or pinion carrier fail the entire
unit must be replaced.
DIAGNOSIS AND TESTING
SEAL IDENTIFICATION
For accurate seal diagnosis, repair seal name and
location is critical. Refer to (Fig. 2), (Fig. 3), (Fig. 4)
and (Fig. 5) for correct seal name and location.
