3. If the crank rod pin location is 180_ from the dial
indicator (opposite that shown above), it will be
necessary to spread the crankshaft at position A
as shown in the illustration at right. When
rebuilding and straightening a crankshaft, runout
must be as close to zero as possible.
NOTE: Maximum allowable runout is .0024I.
