- Find dimension
G,
which is the distance from the
park gear hub to the casejoint surface. Zero the
dial indicator on the park gear hub, then move the
indicator to the case surface. Record this
dimension.
- Subtract dimension E from dimension G to find the
total end play.
Example: If G is 25.3 mm and E is 22.4 mm, then
total end play is 2.9 mm. 25.3 mm - 22.4 mm = 2.9
mm.
- Subtract average end play 0.8 mm (0.65 mm - 1.0
mm) from total end play to find the proper
thickness of shim to be used.
Example: 2.9 mm - 0.8 mm = 2.1 mm
- Select a shim which adjusts end play tolerance
closet to 0.8 mm.
- Five thicknesses of shims are available:
- 0.25 mm
- 0.7 mm
- 1.1
mm
- 1.7
mm
- 2.3 mm
In our example, you would pick the 2.3 mm shim.
This would give 0.7 mm tolerance, which is within
the necessary 0.65 mm to 1.0 mm range.
