Procedure
1. Use the following procedure to adjust the total end
play and select a suitable bearing race.
(1) Set the thrust bearing onto the clutch assembly.
(2) Remove the previous race and gasket.
(3) Set the thickest bearing race 2.2 mm (0.087
in) onto the oil pump.
(4) Set the oil pump onto the clutch assembly.
(5) Measure clearance between the transaxle case
and oil pump.
(6) Select a suitable bearing race from the chart
below.
Clearance mm (in) Select this bearing race mm (in)
0.91-1.10 (0.036—0.043) 1.2 (0.047)
0.71-0.90 (0.028-0.035) 1.4 (0.055)
0.51-0.70 (0.020—0.027) 1.6 (0.063)
0.31-0.50 (0.012-0.019) 1.8 (0.071)
0.11-0.30 (0.004-0.011) 2.0 (0.078)
0-0.10 (0-0.003) 2.2 (0.087)
(7) Remove the oil pump.
(8) Place the selected bearing race and a new gas-
ket onto the oil pump.
(9) Install the oil pump onto the clutch assembly.
Tightening torque:
