<Measurement using Solder>

CAUTION

• If the solder is not available, select the spacer

in accordance with Plastigage method.

• If the spacer appropriate for the standard

value cannot be selected using the solder,
select the spacer in accordance with Plasti-
gage method.

Solder

1. Place two pieces of solder (1.0 mm diameter,

about 10 mm long) in the shown locations of the
output shaft ball bearing and the differential ball
bearing.

AK401962

2. Install the converter housing on the transmission

case without applying FIPG. Tighten the mounting
bolts to the specified torque of 48

± 6 N⋅m.

3. Remove the converter housing from the

transmission case and take out the solder pieces
for obtaining the differential bearing end play.

4. Remove the bearing outer race from the converter

housing and take out the solder pieces for
obtaining the output shaft bearing preload.

5. If the solders have not crushed, use thicker

solders (1.6 mm diameter, about 10 mm long) and
repeat steps 2 to 4.

AK305233

6. Measure the thickness of the crushed solder

pieces using a micrometer. Based on the results,
select spacers which adjust the end play and
preload to the following standard values,
respectively, according to the tables below.

Standard value:

Output shaft bearing end play
0.045

− 0.165 mm

<Measurement using Plastigage>

AK402202AD

Plastigage

1. Place two pieces of plastigage (about 10 mm

long) in the shown locations of the output shaft
ball bearing and the differential ball bearing.

2. Install the adjusting spacer having minimum

thickness.

AK401962

3. Install the converter housing on the transmission

case without applying FIPG. Tighten the mounting
bolts to the specified torque of 48

± 6 N⋅m.

4. Remove the converter housing from the

transmission case and take out the plastigage
pieces for obtaining the differential bearing end
play.

5. Remove the bearing outer race from the converter

housing and take out the plastigage pieces for
obtaining the output shaft bearing preload.

6. If the plastigages have not crushed, use thicker

adjusting spacer and repeat steps 3 to 5.

Plastigage

Spacer

7. Measure the width of the each crushed plastigage

at its widest part using a scale printed on the
plastigage package and record the each
measured value. Based on the results which
calculated by the following formula, select spacers
which adjust the end play and preload to the
following standard values, respectively, according
to the tables below.

T = T1 + T2
T: Clearance mm
T1: The crushed plastigage thickness mm
T2: The adjusting spacer thickness used for
measurement mm
