ring.

Note

Do not measure on the end of the locking ring. The circlip could

get pushed away and this would falsify the measurement.

• Example: dimension “B2 ” = 3.00 mm
– Calculate the mean value from “B1 ” and “B2 ”.

Formula: B1 + B2 2

Example:
• 2.92 + 3.002 = 2.96 mm
• Result: dimension “B” = 2.96 mm
– Remove the circlip again and dispose it.

Step 3: Determine the Dimension “A 1” for the “K 1” Clutch En‐

gaging Bearing.

– Place the Setting Tool - Release Bearing - T10374- with the

large opening downward on the larger engaging bearing.

– Press and turn the Setting Tool - Release Bearing - T10374-

to make sure the Setting Tool - Release Bearing sits correctly

on the engaging bearing.

• The engaging bearing turns with the Setting Tool - Release

Bearing - T10374- .

the Ruler (2 pc.) - T40100- and position the depth slide on the

outer input shaft.

• The Ruler (2 pc.) - T40100- lies straight across the transmis‐

sion flange over the end of the shaft.

Caution

There is the risk of incorrect measurements.

♦ The Ruler (2 pc.) - T40100- should stay in this position for

the following measurements. Do not move it or take if off.

– Set the Depth Gauge to “0”.

– Position the depth gauge on the Setting Tool - Release Bear‐

ing - T10374- as shown.

– Measure dimension “A 1a ” at this position on the Setting Tool

- Release Bearing - T10374- .

• Example: dimension “A 1a ” = 2.61 mm

26

Setting Tool - Release Bearing - T10374- .

• Example: dimension “A 1b ” = 2.81 mm
– Calculate the average value from dimension “A 1a ” and “A

1b ”.
Formula: A 1a + A1b 2

Example:
• 2.61 + 2.812 = 2.71 mm
• Result: dimension “A 1” = 2.71 mm
Step 4: Measuring the Installation Depth for the “K 1” Clutch En‐

gaging Bearing.

Note

Based on dimension “A 1” and dimension “B”, calculate the actual

value for the “K 1” clutch engaging bearing as follows:

 

Dimension “A 1”

Dimension “B”

+

Outer Setting Tool - Release Bearing - T10374- height

(51.81 mm; fixed value)

=

Actual value of the “K 1” clutch engaging bearing installa‐

tion depth

Example:
• 2.71 mm – 2.96 mm + 51.81 mm = 51.56 mm
• Result: installation depth for “K 1” clutch engaging bearing =

51.56 mm

Step 5: Measure the Air Gap for “K 1” Clutch.

Note

Based on the actual value and the specified value of the installa‐

tion depth for the engaging bearing, the air gap for “K 1” clutch is

measured as follows:

 

Engaging bearing installation depth actual value

Engaging bearing installation depth specified value (50.08

mm; fixed value)

=

Air gap for “K 1” clutch

Example:
• 51.56 mm – 50.08 mm = 1.48 mm
• Result: “K 1” clutch air gap = 1.48 mm

illustrated.

Step 7: Measure the “SK 1” Shim Thickness.

Note

Based on the air gap and the clutch tolerance for the “K 1” clutch,

now the “SK 1” shim thickness can be calculated as follows:

 

Air gap for “K 1” clutch

–/+ Clutch tolerance for clutch “K 1”
=

Calculated thickness for shim “SK 1”

Example:
• 1.48 mm + 0.20 mm = 1.68 mm
• Result: calculated “SK 1” shim thickness = 1.68 mm

– Measure the needed shim from the shims supplied and keep

it close for installation.

• Selected shim thickness = 1.60 mm

Caution

Risk of damaging the transmission.

♦ Mark the shim with “SK 1” and keep it ready for assembly.
♦ Only this “SK 1” shim may be inserted to adjust the small

engaging bearing.
