FRAME 2

NOTE

Cylinder bores (2) in crankcase (1) are machined to

two different sizes. Cylinder sleeves are also machined

to two different sizes to fit different size cylinder bores.

The two sizes of cylinder bores and cylinder sleeves are

called "Y" and "Z".

All six cylinder bores (2) are not always the same size.

Cylinder bores (2) and cylinder sleeves are called by

numbers one to six counting from front to rear of

crankcase.

1.

Look at left side of crankcase (1) opposite each cylinder bore (2) about one

inch below top of crankcase. The letter "Y" opposite a cylinder bore means

this is a Y-size cylinder bore. The letter "Z" opposite a cylinder bore means

this is a Z-size cylinder bore.

NOTE

Readings must be within limits given in table 4-28. If

readings are not within given limits, throw away part

and get a new one.

2.

Measure inside diameter of all six cylinder bores (2). Note this measurement

and the number cylinder it was taken from.
