Use a gauge to check the inside measurement of the cylinder bore [Figure 60-90-12].
Measure the six points as shown in [Figure 60-90-13] to find the maximum wear.
The specifications are 87,0 – 87,02 mm (3.425 – 3.426 in).
The wear limit is +0,15 mm (+0.006 in).
If the cylinder bore is not within specifications, re-bore the cylinder for oversize piston.
