Crankshaft Runout/
Repair Specifications
For those who have crankshaft work sent out to another shop, it is advisable to provide them with this information.
To use the specifications, first refer to the drawing; then find the letter which indicates the specification and refer to
the chart below the illustration. Be sure to note the proper engine column. Specifications are called out in both mil-
limeters and inches.
NOTE: We have given the proper location for checking crankshaft runout as the very edge of the straight
portion of the shaft where the oil seal makes contact. From the illustration, note that Arctic Cat has called
out three check points: at either end, out on the taper as shown, and also on the center bearing race. The
crankshaft is still supported on the outer bearings using V blocks. The maximum runout shouldn’t exceed
0.05 mm (0.002 in.).
728-144A
NOTE: Measure in from the shaft end the specified amount when checking runout at points D and F.
When checking runout in the center, place indicator on center of bearing as shown at point E. Maximum
runout at any of the 3 measuring points is ±0.05 mm (0.002 in.).
