(5) Cylinder

Cylinder Wear
1. Measure the I.D. of the cylinder at the six positions (see figure)
with a cylinder gauge to find the maximum and minimum I.D.'s.
2. Get the difference (Maximum wear) between the maximum and
the minimum I.D.'s.
3. If the wear exceeds the allowable limit, bore and hone to the
oversize dimension. (Refer to "Correcting Cylinder".)
4. Visually check the cylinder wall for scratches. If deep scratches
are found, the cylinder should be bored. (Refer to "Correcting
Cylinder".)

NOTE
• When the oversize cylinder is worn beyond the allowable
limit, replace the cylinder block with a new one.
