Stevens A8520 Reamer?

[meskhov]

Just found this in some tools I bought at the fleamarket.
Can anyone tell me what this reams on a Model A? It is a .625" size.
Thanks

I don't think it fits anything on an A that I can recall. The brake actuating shafts are .559 and the next closest is the rear brake shaft at .688.

By the 8520 number would it be for a water pump? The water pump number is 8501.

What is the wrist-pin diameter? I'm thinking piston bushings maybe?

Water pump rear bushing is A8520. Water pump shaft is .625.

If it was a water pump reamer wouldn't the reamer size have to be larger than .625 pump shaft size?
