n. Insert SST and measure turning torque of final drive assembly.
^ Turn final drive assembly in both directions several times to seat bearing rollers correctly.
Turning torque of final drive assembly (New bearing): Refer to AT-345, "Final Drive". Final Drive
^ When old bearing is used again, turning torque will be slightly less than the above.
^ Make sure torque is close to the specified range.

REDUCTION PINION GEAR BEARING PRELOAD
1. Select proper thickness of reduction pinion gear adjusting shim using the following procedures.





a. Place reduction pinion gear on transaxle case as shown in the figure.

c. Place idler gear bearing inner race on outer race.
d. Measure dimensions "B", "C" and "D", and calculate dimension "A".
"A": Distance between the surface of idler gear bearing inner race and the adjusting shim mating surface of reduction pinion gear.
A = D - (B + C)





^ Measure dimension "B" between the end of reduction pinion gear and the surface of transaxle case.
^ Measure dimension "B" in at least two places, and take the average.





^ Measure dimension "C" between the surface of idler gear bearing inner race and the surface of transaxle case.
^ Measure dimension "C" in at least two places, and take the average.





^ Remove reduction pinion gear from transaxle case.
^ Measure dimension "D" between the end of reduction pinion gear and the adjusting shim mating surface of reduction pinion gear.
^ Measure dimension "D" in at least two places, and take the average.
^ Calculate dimension "A".
A = D - (B + C)





e. Measure dimension "E" between the end of idler gear and idler gear bearing inner race mating surface of idler gear.
^ Measure dimension "E" in at least two places, and take the average.
f. Select proper thickness of reduction pinion gear adjusting shim. Refer to "Parts Information" for reduction pinion gear adjusting shim selection.
Proper shim thickness = A - E - 0.05 mm (0.0020 in)*
(*: Bearing preload)





2. Install reduction pinion gear and reduction pinion gear adjusting shim selected in step 1-f on transaxle case.

CAUTION: Apply ATF to reduction pinion gear bearing.

3. Press idler gear bearing inner race on idler gear.
4. Press idler gear on reduction pinion gear.

CAUTION:
^ Apply ATF to idler gear bearing.
^ Press idler gear until idler gear fully contacts reduction pinion gear bearing adjusting shim.

5. Set manual shaft in "P" position to fix idler gear.
6. Tighten lock nut of idler gear to the specified torque. Refer to AT-230, "Component". Component

CAUTION: Lock idler gear with parking pawl when tightening lock nut.





7. Measure turning torque of reduction pinion gear.
Turning torque of reduction pinion gear: Refer to AT-345, "Reduction Pinion Gear". Reduction Pinion Gear
^ When measuring turning torque, turn reduction pinion gear in both directions several times to seat bearing rollers correctly.
^ If turning torque is out of specification, decrease or increase thickness of reduction pinion gear adjusting shim.





8. After properly adjusting turning torque, clinch idler gear lock nut as shown.

CAUTION: Do not reuse idler gear lock nut.

OUTPUT SHAFT END PLAY





1. Select proper thickness of output shaft adjusting shim using the following procedures.





a. Install bearing retainer (1) in transaxle case.





b. Install needle bearing on bearing retainer.

CAUTION: Be careful to direction of needle bearing.





c. Install output shaft on transaxle case.





d. Measure dimensions "l1" and "l2" at side cover and then calculate dimension "A".
^ Measure dimension "l1" and "l2" in at least two places.
"A": Distance between transaxle case fitting surface and adjusting shim mating surface.
A = l1 - l2.
l2: Height of gauge





e. Measure dimensions "l2" and "l3" and then calculate dimension "B".
Measure dimension "l2" and "l3" in at least two places.
"B": Distance between the end of output shaft bearing outer race and the side cover fitting surface of transaxle case.
B = l2 - l3
l2: Height of gauge





f. Select proper thickness of output shaft adjusting shim so that output shaft end play (clearance between side cover and output shaft bearing) is within specifications. Refer to "Parts Information" for output shaft adjusting shim selection.
Output shaft end play (A - B): Refer to AT-346, "Output Shaft". Output Shaft
g. Install output shaft adjusting shim on output shaft bearing.





2. Apply recommended sealant (Genuine Anaerobic Liquid Gasket or equivalent.) to transaxle case as shown in figure.
<---: Inside of side cover
"A": 3 - 5 mm (0.12 - 0.20 in)
"B": 8 mm (0.31 in).
"C": 1.5 mm (0.059 in) dia.
"D": 4 mm (0.16 in)

CAUTION:
^ Apply the sealant on the center between the bolt holes.
^ Completely remove all moisture, oil and old sealant, etc. from the transaxle case and side cover mounting surfaces.





3. Fit mounting part of output shaft bearing on side cover to output shaft bearing, and after adjusting knock pin position, install it with light taps of a soft hammer and things like that.

CAUTION: When installing, to avoid getting damaged and deformed, set mounting part straight to parallel with the mounting surface.





4. Tighten side cover fitting bolts to specified torque. Refer to AT-230, "Component". Component

CAUTION
^ Do not mix bolts A and B.
^ Always replace bolts A as they are self-sealing bolts.
