BobCat 753 – RECONDITIONING THE ENGINE – Checking The Cylinder Bore

Use a gauge to check the inside measurement of the cylinder bore [Figure 70-100-84].

Measure the six points as shown in [Figure 70-100-85] to find the maximum wear.

The specification is 3.4252-3.4261 inches (87,0-87,022 mm). The wear limit is +0.0059 inch (+0,15 mm).

If the cylinder bore is not within specifications, re-bore the cylinder for oversize piston.
