Bore Alignment - Measurement

Caution: The flywheel housing bore and the surface

must be in alignment with the crankshaft to prevent

possible damage to the engine, the clutch, or the trans-

mission.

Use chalk to mark the housing at the 12:00 o’clock, 3:00

o’clock, 6:00 o’clock, and 9:00 o’clock positions.

Use dial gauge indicator (1), Part No. 3376050, and dial

gauge attachment (2), Part No. ST-1325, to measure the

bore alignment.

Attach a dial indicator to the crankshaft as shown.

NOTE: The indicator arm must be rigid for an accurate

reading. It must not sag.

Put the indicator at the 12:00 o’clock position. Adjust the

dial indicator until the needle points to ‘‘0.’’

Rotate the crankshaft one complete revolution in a clock-

wise direction (viewed from the front of the engine).

Record the indicator reading at three different positions:

3:00 o’clock, 6:00 o’clock, and 9:00 o’clock.

Continue rotating the crankshaft until the dial indicator is

at the 12:00 o’clock position.

Check the dial indicator to make sure the needle still

points to ‘‘0.’’
