NOTE: The timing tool indicator needles will both start to

move in the same direction of rotation as the piston ap-

proaches TDC if the cylinder is on the compression stroke.

If both needles do not move in the same direction, rotate the

engine one complete revolution in the same direction of

rotation.

The next frames explain proper orientation and measure-

ment with the dial indicators.

Caution: Both indicators must have a travel range of at

least 6.35 mm [0.250-inch] or the indicators will be dam-

aged.

Put the piston travel dial indicator over the plunger rod

with the contact tip in the center of the piston plunger rod.

Lower the indicator to within 0.63 mm [0.025-inch] of the

fully compressed position.

Tighten the thumbscrew to hold the gauge in position.

Rotate the crankshaft back and forth to make sure the

piston is precisely at top dead center (TDC) on the com-

pression stroke.

NOTE: Always set the dial indicator at ‘‘0’’ (zero) at TDC

with the crankshaft having just been rotated in the direction

of normal rotation (clockwise) to reduce the timing errors

due to gear backlash.

NOTE: TDC is indicated by the maximum clockwise posi-

tion of the piston travel indicator pointer.

Set the dial indicator at ‘‘0’’ (zero). Lock the indicator face

with the thumbscrew.

Rotate the crankshaft in the direction of engine rotation

(clockwise ) to 90 degrees after top dead center (ATDC).

NOTE: The piston travel plunger will be at the ‘‘NH/NT

90-degree’’ mark on the timing tool.
