Note

Sand in a crisscross pattern. Do not sand excessively.

4. Inspect: •Cylinder wall

Wear/Scratches-^Rebore or replace.

5. Measure:

• Piston-to-cylinder clearance

Piston-to-cylinder clearance measurement steps:

First steps

• Measure the cylinder bore "C" with a cylinder bore gauge. @ 40 mm (1.57 in) from the cylinder top

Measure the cylinder bore "C" in parallel to and at right angles to the crankshaft.

Then, find the average of the measurements.

Cylinder Bore "C":

82.97 - 83.02 mm

(3.267 - 3.269 in)

< Limit: 83.10 mm (3.272 in)>

• If out of the specification, rebore or replace the cylinder, and the piston and piston rings as a set.

2nd steps

• Measure the piston skirt diameter "P" with a micrometer. (B) 4 mm (0.16 in) from the piston bottom edge

Piston skirt diameter "P": 82.04 - 82.05 mm (3.2299 - 3.2303 in)

• If out of the specification, replace the piston and piston rings as a set.

3rd steps

• Find the piston-to-cylinder clearance with following formula.

Piston-to-cylinder clearance = Cylinder bore "C"-Piston skirt diameter "P"

Piston-to-cylinder clearance: 0.040 - 0.060 mm (0.0016 - 0.0024 in) < Limit: 0.15 mm (0.006 in)>

1 If out of the specification, rebore or replace the cylinder, and replace the piston and piston rings as a set.
