Typical example
1. Use Tooling (A) and Tooling (B) in order to measure
the piston height above the cylinder block. Use the
cylinder block face to zero Tooling (A).
2. Rotate the crankshaft until the piston is at the
approximate top center.
3. Position Tooling (B) and Tooling (A) in order to
measure the piston height above the cylinder
block. The piston height should be measured at
positions (X) or (Y). Slowly rotate the crankshaft in
order to determine when the piston is at the
highest position. Record this dimension. Compare
this dimension with the dimensions that are given
in Specifications, “Piston and Rings”.

Dial Indicator Group 1
Alignment of the Flywheel Face
Illustration 70 g01332565
Typical example
1. Install Tooling (A) in illustration 70 , as shown.
2. Set the pointer of the dial indicator to 0 mm
(0 inch).
3. Turn the flywheel. Read the dial indicator for every
45 degrees.
Note: During the check, keep the crankshaft pressed
toward the front of the engine in order to remove any
end play.
4. Calculate the difference between the lowest
measurement and the highest measurement of the
four locations. This difference must not be greater
than 0.03 mm (0.001 inch) for every 25 mm
(1.0 inch) of the radius of the flywheel. The radius
of the flywheel is measured from the axis of the
crankshaft to the contact point of the dial indicator.
