Crankshaft Truing
Lubricate the bearings and clamp the crankshaft securely
in the holding fixture. If truing the crankshaft requires
striking with a hammer, always be sure to re-check
previously straightened areas to verify truing. Refer to the
illustrations below. Use Crankshaft alignment kit PN
2870569.
NOTE: The Rod Pin position in relation to the dial
indicator tells you what action is required to
straighten the shaft.
Truing Examples
To correct a situation like this. Strike the shaft at
point A with a brass hammer.
To correct a situation like the one shown in this.
Squeeze the crankshaft at point A. You will use the
tool from the alignment kit PN 2870569.
If the crank rod pin location is 180° from the dial
indicator (opposite of above), it will be necessary to
spread the crankshaft at the A position as shown in
illustration 3. When rebuilding and straightening a
crankshaft, straightness is of utmost importance.
Runout must be as close to zero as possible.
