Transmission Cover
A: REMOVAL1) Remove transmission cover.
2) Take out shim from transmission cover.
B: INSTALLATION
1) Measure distance L from end of transmission cover point at bearing location with ST.
ST 398643600 GAUGE
L = Measured value - 15 mm
2) Measure the distance "l" from the transmission case mating surface to end of bearing with ST.
l = Measured value - 15 mm
ST 398643600 GAUGE
3) Calculation equation:
NOTE: Add 0.05 mm (0.0020 inch) and 0.20 mm (0.0079 inch) thick shims to area "T". Calculate formula 2 to determine "H". The calculated "H" refers to the shim thickness range. Select shims of suitable thicknesses within the calculated "H" range.
(0 to 6 teeth)
T = (L + G) - l - H
T: Shim clearance
L: Distance from end of extension case to end of rear drive shaft
G: Gasket thickness [0.45 mm (0.0177 inch)]
l: Height from end of transmission case to end of reduction drive gear
H: Shim thickness: 0.05 - 0.25 mm (0.0020 - 0.0098 inch)
4) Attach the selected adjusting shim to transmission cover.
5) Install the transmission cover to the transmission case.
CAUTION: Be sure to use a new gasket.
6) Tighten bolts to secure the case.
Tightening torque: 25 Nm (2.5 kgf-cm, 18.1 ft. lbs.)
C: INSPECTION
Make sure that the transmission cover has no cracks.
