Chrysler New Yorker. Manual — part 291
OIL PUMP INSPECTION
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. 87).
(3) Remove the pump gears and check for wear
and damage.
(4) Install the gears and check clearances.
(5) Measure the clearance between the outer gear
and the pump pocket (Fig. 88). Clearance should be
0.045-0.141mm (0.0018-0.0056 in.)
(6) Measure the clearance between the outer gear
and the pump crescent. Clearance should be 0.020-
0.046mm (0.0008-0.0018 in.) (Fig. 89).
(7) Measure the clearance between the inner gear
and the pump crescent. Clearance should be 0.020-
0.046mm (0.0008-0.0018 in.) (Fig. 90).
CAUTION: By-pass valve must be replaced if trans-
mission failure occurs.
The number 7 needle bearing has antireversal tabs
and is common with the number 5 and number 2
position. The orientation should allow the bearing to
seat flat against the rear sun gear (Fig. 98). A small
amount of petrolatum can be used to hold the bear-
ing to the rear sun gear.

DISASSEMBLY AND ASSEMBLY (Continued)
Stand trans upright on bellhousing.
Chain cover must be free of old sealant, dirt and
oil before applying new sealant. Apply a 1/8 inch
bead of sealant to flange of cover.
CAUTION: Be sure to reinstall the chain snubber
and chain oiler when reassembling.
CAUTION: The chain sprockets have a slip fit onto
the shafts. Apply only a slight amount of pressure
to the chain spreader to release the chain pressure.
If chain sprockets are not spread slightly, removal
or installation will be difficult. Overspreading of the
chain sprockets will also make sprocket removal
difficult.
Remove main sump baffle from transaxle case (Fig.
116).
