7C ASSEMBLY
7C-112
Procedure
1. Use the following procedure to adjust the total end
play and select a suitable bearing race.
(1) Remove the pump cover from the oil pump.
(2) Install the bearing into the rear clutch drum.
(3) Mount the bearing race to the pump cover; and
then install it into the front clutch drum.
Note
A front clutch drum end play adjust shim must
not be used between the pump cover and the
front clutch drum when checking total end
play.
(4) Position a straight edge on the transaxle case,
and measure the clearance between the
straight edge and either the pump cover or the
transaxle case.
a) If the pump cover surface is lower than the
transaxle case, measure the clearance be-
tween the straight edge and the pump
cover.
Specification:
0.10 mm (0.004 in) max.
Note
a) Make the measurement without the oil
pump gasket installed.
b) Measured clearance plus thickness of oil
pump gasket equals total end play.
b) If the pump cover surface is higher than the
transaxle case, measure the clearance be-
tween the straight edge and the transaxle
case.
Specification:
0.15 mm (0.006 in) max.
Caution
Do not position the straight edge on the bolt
holes for mounting the oil pump to the trans-
axle case.
Note
Thickness of oil pump gasket minus measured
clearance equals total end play.
2. If the end play is not within specification, adjust it
by selecting the proper bearing race.
Caution
Use only one bearing race.
Bearing race outer diameter: 41.0 mm (1.61 in)
Bearing race sizes mm (in)

1.2 (0.047) 1.4 CO.055) 1.6 (0.063)
1.8 (0.071) 2.0 (0.079) 2.2 (0.087)

3. Reinstall the oil pump cover.
Tightening torque: 11—14 N-m
(110—140 cm-kg, 95—122 in-lb)

4. Use the following procedure to adjust the front
clutch drum end play and select the adjust shim.
(1) Set the oil pump gasket onto the transaxle
case.
(2) Place the adjust shim onto the front clutch
drum.
(3) Install the oil pump and bearing race into the
transaxle; then tighten the oil pump mounting
bolts to the specified torque.
Tightening torque:
15—22 N m (1.5—2.2 m-kg, 11—16 ft-lb)

(4) Position the transaxle with the oil pump facing
down ward position.
(5) While turning the connecting shell 2 complete
turns, push the front clutch drum toward the
oil pump with a screwdriver to seat the front
clutch drum.
(6) Measure the clearance between the front clutch
drum and the connecting shell. This clearance
is the front clutch drum end play.
End play: 0.5—0.8 mm (0.020—0.031 in)
(7) If the end play is not within specification, ad-
just it by selecting the proper adjust shim.

7. Adjust the band brake.
(1) Apply sealant to threads; and tighten the
anchor-end bolt.
Tightening torque: 12—15 N-m
(120—150 cm-kg, 104—130 in-lb)
(2) Loosen the anchor-end bolt 2 turns.
(3) Tighten the locknut to the specified torque.
Tightening torque:
