4WD : Inspection and Adjustment

INFOID:0000000010919409

INSPECTION AFTER DISASSEMBLY

Case and Housing

• Check the bearing mounting surface for wear, cracks, and damages. Replace if necessary.
• Check the mating surface for wear, cracks, and damages. Replace if necessary.
• Check the oil seal mounting surface for wear, cracks, and damages. Replace if necessary.

Bearing

Check the bearing for damage and unsmooth rotation. Replace if necessary.

ADJUSTMENT

Differential Side Bearing Preload

• When adjusting differential side bearing preload, select adjusting

shim for differential side bearing. To select adjusting shim 

, mea-

sure clearance (L) between transaxle case 

 and differential side

bearing outer race 

. For selecting adjusting shim, refer to the lat-

est parts information.

CAUTION:

Up to 2 adjusting shims can be selected.

• Calculate dimension (L) (thickness of adjusting shim) using the fol-

lowing procedure to satisfy specification of preload for differential
side bearing.

1.

Using a depth micrometer and a straightedge, measure dimen-
sion (L

1

) between transaxle case end face and mounting face of

adjusting shim.

CAUTION:

L

1

: Measure at 4 point by approximately 90 degrees and use

the average value.

2.

Install differential side bearing outer race onto differential side
bearing on transaxle case side. Holding lightly differential side
bearing outer race horizontally by hand, rotate final gear five
times or more (for smooth movement of bearing roller).

3.

Using a depth micrometer and a straightedge as shown in the
figure, measure dimension (L

2

) between differential side bearing

outer race and clutch housing end face.

CAUTION:

L

2

: Measure at 4 point by approximately 90 degrees and use

the average value.

Install selected differential side bearing adjusting shim and then
install differential side bearing outer race (transaxle case side)
using the drift (A) (SST: ST30720000).

CAUTION:

Replace differential side bearing and differential side bear-
ing outer race as a set.

Reverse Idler Gear End Play

• When adjusting reverse idler gear end play, select adjusting shim

for reverse idler gear. To select adjusting shim 

, measure clear-

ance between transaxle case 

 and reverse idler gear (rear) 

.

For selecting adjusting shim, refer to the latest parts information.

CAUTION:

Only 1 adjusting shim can be selected.

• Calculate dimension (Q) (thickness of adjusting shim) using the fol-

lowing procedure to satisfy specification of end play for reverse
idler gear.

1.

Using a depth micrometer and a straightedge, measure dimen-
sion (Q

1

) between transaxle case end face and mounting face of

adjusting shim.

2.

Using a depth micrometer and a straightedge as shown in the
figure, measure dimension (Q

2

) between clutch housing 

 end

face and end face of reverse idler gear (rear) 

.

CAUTION:

Q

2

: Measure at 4 point by approximately 90 degrees and

use the average value.

3.

Install selected reverse idler gear adjusting shim onto reverse
idler gear (rear).

TRANSAXLE ASSEMBLY

• When adjusting input shaft end play, select adjusting shim for input

shaft rear bearing. To select adjusting shim, measure clearance
between transaxle case and input shaft rear bearing. For selecting
adjusting shim, refer to the latest parts information.

CAUTION:

Only 1 adjusting shim can be selected.

• Calculate dimension (O) (thickness of adjusting shim) using the fol-

lowing procedure to satisfy specification of end play for input shaft
rear bearing.

1.

Using a depth micrometer and a straightedge, measure dimen-
sion (O

1

) between transaxle case end face and mounting face of

adjusting shim.

CAUTION:

O

1

: Measure at 4 point by approximately 90 degrees and

use the average value.

2.

Using a depth micrometer and a straightedge as shown in the
figure, measure dimension (O

2

) between clutch housing end

face and end face of input shaft rear bearing.

CAUTION:

O

2

: Measure at 4 point by approximately 90 degrees and

use the average value.

3.

Install selected input shaft rear bearing adjusting shim onto input
shaft.

Striking Rod End Play

• When adjusting striking rod end play, select adjusting shim for

striking rod. To select adjusting shim 

, measure clearance

between transaxle case 

 and striking rod shim 

. For selecting

adjusting shim, refer to the latest parts information.

CAUTION:

Only 1 adjusting shim can be selected.

• Calculate dimension (R) (thickness of adjusting shim) using the fol-

lowing procedure to satisfy specification of end play for striking
rod.
