REVERSE IDLER GEAR END PLAY ADJUSTMENT

AME511201029M06

Note

•

Adjust the reverse idler gear end play by measuring the clearance between the transaxle case and a 
reverse idler gear (rear), and selecting a reverse idler gear adjustment shim.

•

Calculate dimension Q for the adjustment 
shim thickness as defined below to adjust 
the reverse idler gear end play to standard 
value.

Standard value: 0.04—0.10 mm 

{0.0016—0.0039 in}

Dimension Q = (Q1 + Q2) + end play

Q: adjustment shim thickness
Q1: transaxle case contact face and 

adjustment shim installation surface 
dimension

Q2: clutch housing contact face and 

reverse idler gear (rear) contact face 
dimension

Adjustment shim thickness

(mm {in})

1. Measure dimension Q1 between clutch housing 

installation surface of the transaxle case and 
adjustment shim installation surface using a 
depth gauge and straight edge.

2. Measure dimension Q2 between the transaxle 

case installation surface of the clutch housing and 
the reverse idler gear (rear) contact face using a 
depth gauge and straight edge.

Note

•

Select only one adjustment shim.

3. Install the selected reverse idler gear adjustment 

shim in the reverse idler gear component.

MANUAL TRANSAXLE 

DIFFERENTIAL SIDE BEARING PRELOAD ADJUSTMENT

AME511201029M05

Note

•

Adjust the differential side bearing preload by measuring clearance L between the transaxle case and the 
differential side bearing outer race, and selecting a differential side bearing adjustment shim.

•

Calculate dimension L for the adjustment 
shim thickness as defined below to adjust 
the differential side bearing preload to 
standard value.

Standard value: 0.15—0.21 mm 

{0.0059—0.0083 in}

Dimension L = (L1 + L2) + preload

L: adjustment shim thickness
L1: transaxle case contact face and 

adjustment shim installation surface 
dimension

L2: clutch housing contact face and 

differential side bearing contact face 
dimension

Adjustment shim thickness

(mm {in})

1. Measure dimension L1 between the clutch 

housing installation surface of the transaxle case 
and the adjustment shim installation surface 
using a depth gauge and straight edge. 

2. Install the outer race to the ring gear side of the 

differential side bearing and, keeping the outer 
race level, lightly push it in and rotate the final 
gear 5 times or more.

3. Verify dimension L2 between the differential side 

bearing outer race and the transaxle case 
installation surface of the clutch housing using a 
depth gauge and straight edge.

Note

•

Select up to 2 adjustment shims.
