MODIFICATION DETAIL



SERVICING

When the transmission case housing is installed on the transmission case after the differential case has been replaced, perform the shim adjustment in the following procedures.


NOTE:
When carrying out the following measurement, make sure to remove the gasket both from the transmission case housing and the transmission case.






1) Place a straightedge across the transmission case housing and measure the distance "A" using a vernier caliper. The distance "A" can be obtained by subtracting the straightedge thickness "C" from the distance "B". [A=B-C]






2) In the similar manner to step 1, calculate the transmission case distance "D". The distance "D" can be obtained by subtracting the thickness "C" from the distance "E". [D=E-C]






3) Using a vernier caliper, measure the differential distance "F" (bearing to bearing), as shown in the illustration.



4) Obtain the value "G" by adding together the distance "A" in step 1 to distance "D" in step 2, plus 0.4 mm (0.0157in.). [G=A+D+0.4 mm]

NOTE:
The dimension 0.4 mm is equivalent to gasket thickness.


5) Obtain the value "H" by adding 0.2 mm (0.0079 in.) to the distance "F" in step 3. [H=F+0.2 mm]


NOTE:
The value 0.2 mm is intended to absorb the measurement error.

6) Obtain the value "t" by subtracting "H" in step 5 from distance "G" in step 4. [t=G-H]

7) Select the shim, the thickness of which is the closest to the value "t" (according to the chart) and install it to the position indicated in the illustration.

CAUTION:
The thickness selected must be thinner than the value t as calculated in step 6.


Available shim thickness:

0.56 mm (0.022 in.)
0.7 mm (0.0275 in.)
0.8 mm (0.0314 in.)
0.9 mm (0.0354 in.)
