Piston Assembly


You have the wrong bearing for the model year of the rod. Either you are trying to put an early bearing on a late model rod or visa versa.

As you noted, the bearings are the same except for the tab. I understand that one of the major bearing manufactures is soon going to eliminate the tab altogether.

I was hoping it was just a mismatch that different bearings could solve. I really don't want to disassemble the pistons. Since this was a complete package I'm sure TMD will correct it.
