OIL PUMP
DESCRIPTION
The oil pump is located in the pump housing inside
the bell housing of the transaxle case (Fig. 295). The
oil pump consists of an inner and outer gear, a hous-
ing, and a cover that also serves as the reaction shaft
support.
OPERATION
As the torque converter rotates, the converter hub
rotates the inner and outer gears. As the gears
rotate, the clearance between the gear teeth
increases in the crescent area, and creates a suctionat the inlet side of the pump. This suction draws
fluid through the pump inlet from the oil pan. As the
clearance between the gear teeth in the crescent area
decreases, it forces pressurized fluid into the pump
outlet and to the valve body.
STANDARD PROCEDURE - OIL PUMP VOLUME
CHECK
Measuring oil pump output volume will determine
if sufficient flow to the transmission oil cooler exists,
and whether or not an internal transmission failure
is present.
Verify that transmission fluid is at the proper
level. If adding fluid is necessary, fill to the proper
level with Moparž ATF+4 (Automatic Transmission
Fluid±Type 9602). The following procedure is to
check oil pump output volume:
(1) Using hose cutters or a suitable blade, cut the
ªto coolerº (Fig. 296) line off flush with the cooler
inlet fitting and place a collection container under
the open line .
CAUTION: With the fluid set at the proper level,
fluid collection should not exceed (1) quart or inter-
nal damage to the transmission may occur.
(2) Start engine and runat curb idle speed, with
the shift selector in neutral.

less, flow is within acceptable limits. If fluid flow is

(3) If one quart of ATF is collected in 20 seconds or
less, flow is within acceptable limits. If fluid flow is
intermittent or it takes more than 20 seconds to col-
lect one quart of ATF, (Refer to 21 - TRANSMIS-
SION/TRANSAXLE/AUTOMATIC - 41TE -
DIAGNOSIS AND TESTING).
(4) Inspect the cooler hose for damage. Replace if
necessary.
(5) Re-connect the to cooler line to the transmis-
sion using a service splice kit. Refer to instructions
inclued with the kit.
(6) Refill the transaxle to proper level with
Moparž ATF+4 (Automatic Transmission Fluid±Type
9602).
DISASSEMBLY
When disassembling the transaxle it is necessary
to inspect the oil pump for wear and damage.
(1) Remove the reaction shaft support bolts.
(2) Remove reaction shaft support from pump
housing (Fig. 297).
(3) Remove the pump gears (Fig. 298) and check
for wear and damage on pump housing and gears.
(4) Re-install the gears and check clearances.
(5) Measure the clearance between the outer gear
and the pump pocket (Fig. 299). Clearance should be
0.045-0.141mm (0.0018-0.0056 in.).
(6) Position an appropriate piece of Plastigage
across both pump gears.
(7) Align the Plastigage to a flat area on the reac-
tion shaft support housing.
(8) Install the reaction shaft to the pump housing.
Tighten the bolts to 27 N´m (20 ft. lbs.).
(9) Remove bolts and carefully separate the hous-
ings. Measure the Plastigage following the instruc-
tions supplied.(10) Clearance between outer gear side and the
reaction shaft support should be 0.020-0.046 mm
(0.0008-0.0018 in.). Clearance between inner gear
side and the reaction shaft support should be 0.020-
0.046 mm (0.0008-0.0018 in.).
