Transaxle CaseNCMT0023S02
1. Insert differential oil seal into differential case until it becomes
flush with case end face.
2. Install welch plug into transaxle case.
3. Calculate dimension ªNº (thickness of adjusting shim) using
the following procedure to satisfy specification of end play for
differential side bearing.
End play: 0.15 - 0.21 mm (0.0059 - 0.0083 in)
Dimension ªNº = (N1 þ N2) + End play
N : Thickness of adjusting shim
N1: Distance between clutch housing case end
face and mounting face of adjusting shim
N2: Distance between differential side bearing
and transaxle case
Available differential side bearing adjusting shims:
Refer to SDS, MT-92.
a. Using dial gauge and scale, measure dimension ªN1º between
clutch housing case end face and mounting face of adjusting
shim.

b. Install outer race onto differential side bearing on final gear
side. Holding lightly the outer race horizontally by hand, rotate
final gear five times or more (for smooth movement of bearing
roller).
c. Using dial gauge and scale as shown in the figure, measure
dimension ªN2º between differential side bearing outer race
and transaxle case end face.
4. Install selected shim and bearing outer race.
5. Measure turning torque of final drive assembly.
Turning torque of final drive assembly
(New bearing):
2.9 - 6.9 N×m (30 - 70 kg-cm, 26 - 61 in-lb)
IWhen old bearing is used again, turning torque will be
slightly less than the above.
IMake sure torque is close to the specified range.
IChanges in turning torque of final drive assembly per
revolution should be within1.0 N×m (10 kg-cm, 8.7 in-lb)
without binding.
6. Calculate dimension ªOº (thickness of adjusting shim) using
the following procedure to satisfy specification of end play for
input shaft rear bearing.
End play: 0 - 0.06 mm (0 - 0.0024 in)
Dimension ªOº = (O1 þ O2) + End play
O : Thickness of adjusting shim
O1: Distance between transaxle case end face
and mounting face of adjusting shim
O2: Distance between clutch housing case end
face and end face of input shaft rear bearing
Available input shaft rear bearing adjusting shims:
Refer to SDS, MT-91.

plug.)
13. Install speedometer pinion assembly.
CAUTION:
Do not reuse O-ring.
14. Install check springs and check balls. Apply sealant to the
thread on the check plug, and install it.

cedure to satisfy specification of end play for mainshaft rear
bearing.
End play: 0 - 0.06 mm (0 - 0.0024 in)
Dimension ªPº = (P1 þ P2) + End play
