At this point the Centerline of the transaxle has
been removed. If the condition for disassembly did
not pertain to the differential, it’s disassembly may
not be required. Inspect the rear transfer shaft area
and the transfer shaft seal area for contamination. If
evidence of contamination is present, replace the rear
transfer shaft bearing and/or the transfer shaft seal.
OIL PUMP
DISASSEMBLY, INSPECTION, & ASSEMBLY
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. 222).
(3) Remove the pump gears (Fig. 223) and check
for wear and damage.
(4) Re-install the gears and check clearances.
(5) Measure the clearance between the outer gear
and the pump pocket (Fig. 224). Clearance should be
0.045-0.141mm (0.0018-0.0056 in.).
