C2 Throw Out Bearing

[Page C.]

Hi All,
Recently purchased a new GM#15680264 throw out bearing. It was a BCA#614018. It appears that the design of this bearing prevents the inter part that slides on the transmission input bearing collar rotating. The inter part of the bearing that fits in the clutch fork is egg shaped. The only part that can rotate is the part that contacts the clutch fingers. Has anyone had any experience with this type of throw out bearing. It can be changed in about 2 minutes now since the engine is on the stand and the trans is in the floor.
Thanks

I think you'll find that this bearing is about the best one out there. Its appearance belies its functionality. I'm not surprised that this unit is manufactured by BCA. Just about all of Delco parts, especially for older applications, are no longer made by GM or, even, one of the old GM parts manufacturing operations now part of DELPHI. BCA is a major manufacturer of ball bearings for the OEM and aftermarket. I wouldn't be a bit surprised if they manufacture some bearings used for the C6.

The only part of the TO bearing that's supposed to rotate is the face of the bearing that contacts the clutch fingers; the rest of it is stationary, and just slides fore-aft on the front bearing retainer collar.
