Usage:
Remanufactured Crankshafts are available in upgrade to new (standard) and two different undersize dimensions. Availability for all options is now "same as new". This means your stock order will be filled with either an undersize crankshaft or a new crankshaft if necessary. Either way you are assured a crankshaft for the Remanufactured price.
NOTE: You may receive a new, standard journal crankshaft when a .025" undersize was ordered or possibly a .025" crankshaft when the .050" was ordered. So pay special attention to the journal size indicated on the crankshaft container. Be sure to have appropriate bearings on hand to fit the various journal sizes you may receive.
A "second grind" option (usually .050" undersize) has been added to give customers a lower cost alternative to "first grind" (usually .025" undersize) crankshaft repairs. Both options are Remanufactured to new specifications (except journal diameter) and will provide life and performance similar to new. Either crankshaft can be returned for credit on future Remanufactured Crankshaft purchases.
