CYLINDER AND PISTON

ENG

2.Measure:

●Piston-to-cylinder clearance

*****************************************************

Measurement steps: 1st step:

●Measure the cylinder bore “C” with the cylinder bore gauge.

NOTE:

Measure cylinder bore “C” by taking side-to- side and front-to-back measurements of the cylinder. Then, find the average of the measurements.

Cylinder bore “C”	84.500 ~ 84.510 mm
	(3.3268 ~ 3.3272 in)
Max. taper “T”	0.05 mm
	(0.0016 in)
Out of round “R”	0.01 mm
	(0.0004 in)

“C”= maximum of D1 ~ D6

“T”= maximum of D1, or D2 – maximum of D5 or D6

“R”= maximum of D1, D3 or D5 – minimum of D2, D4 or D6

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

2nd step:

●Measure piston skirt diameter “P” with a

micrometer.

a 5.0 mm (0.20 in) from the piston bottom edge

Piston skirt diameter “P”

Standard

84.445 ~ 84.460 mm

(3.3246 ~ 3.3252 in)

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