shims are used, there is a good chance that the mounting surface has been machined down or it is warped. Please refer to
your local machine shop for advice on your block.
4. After adding the shim or shims, recheck the clearance in several different locations, preferably 120 degrees apart.
5. One more critical location to check is the clearance between the flexplate ring gear and starter. Normally this is not an
issue, but make sure there is a 0.100” clearance with a variance of +/- 0.040”. Again check it in several locations. If there
are clearance issues the flexplate may be warped and you should return it to your dealer. Although we check each
flexplate that we manufacture for run out, the flexplate could have been damaged during shipping.

Possible Causes for Damaged Flexplates
1. Not installing flexplate perpendicular to crankshaft flange
2. Engine or torque converter out of balance
3. Worn front pump bushing
4. Too much end play on the crank from excessive thrust bearing wear
5. Improper bolt torque and, or not in proper order according to OEM specs
6. A bad starter can wear or break off the teeth on the ring gear
7. Not properly shimming the starter, if needed, to align with the starter ring

STOP!!!! SPECIAL NOTES:
