Flywheel Face Runout
Install the contact tip of the indicator against the flywheel
face, as close to the outside diameter as possible, to in-
spect the face (1) runout.
NOTE: Push the flywheel forward to remove the crankshaft
end clearance. Adjust the dial on the indicator until the
needle points to zero.
Barring Tool, Part No. 3824591
Use the barring tool, Part No. 3824591, to rotate the crank-
shaft one complete revolution. Measure the flywheel runout
at four equal points on the flywheel.
NOTE: The flywheel must be pushed toward the front of the
engine to remove the crankshaft end clearance each time
a point is measured.
The total indicator reading (TIR) must not exceed the fol-
lowing specifications:

material between the flywheel mounting surface and the
crankshaft flange.
