Hi guys, my engine destroys the main bearing and rotors bearing too, and I already bought the main bearing, I'm going to buy the rotors bearing .... can I buy the bearings from 86-92? They seem to be the same ... thanks

 

Far as i know rotor bearings are the same for ALL 13b's minus the renesis

If you keep eating up bearings, you have an internal problem, whether it be mis matched rotors, an eshaft with alot of runout, oil pressure problems, or too much endplay due to the wrong spacer being used

Engine bearings can last multiple rebuilds if the rebuild is done right, and the engine isn't pushed past its limits

 

why don't you buy the exact bearings that your motor requires instead of piecing it together?

 

The problem came from several factors, the eccentric shaft had much wear and tear when assembled but the bearing is to save a few dollars

 

I would get a new/used/better condition eshaft too then.

also I agree with Iduley, all 13b bearings minus MSP's should be the same. I have somewhat of a frankenstien engine using s5 na rotors, s4 e shaft and I got bearings for an s4 na engine when I rebuilt mine. no issues here
