B. If shimming is required, shim as follows:
1.
Remove shoes and disassemble Kompensator. See Figure 3.
2. Remove bearing plates (ITEM 12 and ITEM 13). Measure thickness if less
than .31˝ (5/16˝) thick. Replace with new Holland part.
3. Install shims.
4. Check for free lateral movement of shoe in frame. DO NOT over shim.
Recheck fore and aft movement of the shoe subassembly. Movement is to
be less than .06˝ (1/16˝).
C. Inspect the cushions (ITEM 5) and other components for distortion and splitting or
cracking. If disassembly is required, follow steps 1–5 under section 4 below, and
replace as required.
4. Kompensator Base Subassembly: Measure Upward Movement
A. Measure upward clearance on
the assembly. Do this on one
side at a time by lifting the fifth
wheel top plate upward manually
with the aid of a bar (see Figure
7). Clamp the shoe (ITEM 2) on
the opposite side to prevent its
movement, which will affect the
measurement (see Figure 7). If the
total movement exceeds 0.5˝ (1/2˝),
the unit should be disassembled
for further inspection.
If disassembly is required, follow the steps below:
1. Remove the fifth wheel top plate from the Kompensator base removing the
appropriate roll pins and bracket pins or cotter pins, nuts and bolts, depending
upon model.
2. Remove all loose internal parts
(shoes, tie rod, etc.).
3. Inspect all parts for distortion, wear
and cracking. Replace if necessary.
4. Measure the thickness of the curved
base of the shoe sub-assembly
(ITEM 2). The shoe should be
replaced if the base thickness
measures less than 0.31˝ (5/16˝).
See Figure 8.
