Repairing Multi-disk Stack of Center Differential Lock (ZS)

B. Measuring (Up To Transfer Case No.26 616)

Multi-disk stack of center differential lock (ZS) without automatic adjustment





Measure dimension "B1". During the measurement, compress multi-disk stack (82 and 83) in the inner multi-disk carrier (86) by hand (numbers 1 and 2).

Measure dimension "B2" at pressure plate (93) using a depth gauge (number 3)

Dimension "M" - Specified value 25.25 mm up to 25.85 mm (number 4).
Dimension "M" = (B1 - B2).

Calculate thickness "S3" of spacer ring (92) (number 5).
S3 = 27.9-(M+0.35).

Note
The dimensions 27.9 mm and 0.35 mm are specified by design.
Spacer rings (92) are available in thicknesses of 1.5 mm to 2.3 mm in increments of 0.1 mm.


Measuring




1 Measure dimension "B1". Place pressure plate and inner multi-disk carrier with multi-disk stack on a measuring plate.

2 Using a caliper gauge measure from the hub of the inner multi-disk carrier to the measuring plate. During the measurement the multi-disk stack must be compressed by hand (arrows).




3 Measure dimension "B2". Measure turned groove of pressure plate (93) with a depth gauge.

4 Calculate dimension "M".
Specified value 25.25 mm- 25.85 mm
Calculation formula : B1-B2 = M

Example:
B1 26.7 mm
B2= 1.2mm
M=26.7 mm - 1.2 mm = 25.5 mm

If the dimension "M" does not correspond to the specified value, it must be corrected by inserting suitable steel multi-disks.
Steel multi-disks are available in thicknesses of 1.8 mm and 2.0 mm.

5 Calculate thickness S3 of spacer ring. Calculation formula : S3 = 27.9-(M + 0.35)
Note The dimensions 27.9 mm and 0.35 mm are specified by design.

Example:
27.9 - (M 25.5 + 0.35) = 25.85
27.9 - 25.85 = 2.05
S3 = 2.05

A spacer ring of 2.1 mm thickness is to be installed.
Spacer rings are available in thicknesses of 1.7 mm to 2.3 mm in increments of 0.1 mm.
