(52)DETERMINING #4 THRUST PLATE
THICKNESS / INPUT SHAFT END PLAY:
(a) Select the thinnest #4 thrust plate thickness
and install to input clutch assembly (Fig. 139). Use
petrolatum to retain.
(b) Install input clutch assembly into position
and verify that it is completely seated by viewing
through input speed sensor hole. If view through
input speed sensor hole is not as shown in (Fig.
140), the input clutch assembly is not seated prop-
erly.
(c) Remove oil pump o-ring (Fig. 141).Be sure
to reinstall oil pump o-ring after selecting the
proper #4 thrust plate.
(d) Install pump and gasket to transmission.
Install and torque bolts.(e) Set up input shaft for measurement with
Indicator Set C3339 and End Play Set 8266 as
shown in (Fig. 142).
(f) Measure the input shaft end play with the
transaxle in the vertical position.Input shaft end
play must be within 0.005 to 0.025 inch.For
example, if end play reading is 0.055 inch, select
No. 4 Thrust Plate which is 0.071 to 0.074 thick.
This should provide an input shaft end play read-
ing of 0.020 inch which is within specifications.
(g) Refer to the No. 4 thrust plate chart to select
the proper No. 4 thrust plate:
