S.S.Bearing

[Dave Smith]

Mike:  Also forgot to mention that Tower does not say this is stainless,but it is a few dollars more.  If I was to run a bearing that came with seals,I would remove them just on the chance the seals might let go.   The grease will come out anyway in a few runs.
Here are the dimensions:  PN # 46030008,  NSK 6904: - from the 140RX parts list:- OD 37MM,   ID 20MM,  W 9MM.

# 29430010 from the 140EFI Parts List:- 
OD 36.9MM,   ID 20.0MM  H(W?) 8.8MM

So far,I have no real complaints about the rear bearings in my 140RX,but when the time comes I will check a local bearing supply outlet for a stainless one.

Verne,do you have any comments??

      Dave, I was unaware of the differance in size, but I know for a fact that Verne Koester is running one in his O.S. 140 RX, and I got that p/n off of his spare bearing package.  What was the differance in the bearing size?  If it is slightly wider or narrower, it will most likely not make a differance, as long as the i.d. and o.d. is the same size.  Maybe Verne will chime in on this thread and let us know for sure.

    "  learned from other peoples experience that the best stainless steel bearing
    is the O.S. FI factory bearing p/n 29430010.  That is the bearing I will be
    using next, and I was told to leave the seals in the bearing to maintain the
    factory grease in the bearing."


    Mike:     On checking with Tower,the stainless bearing will not be available until October.

    Also,their specs show it to be very slightly different in size than the one they list for the 140RX.    Would this be a problem?
