Help deciphering bearing grinding marks
I have disassembled my 1500 T1 motor and it has the following inscription painted on the motor. I know it most probably is the undersize oversize
markings, but is there a specific code that would have been used? The motor I believe was originally fully refurbished by Volkswagen King in
Sydney.
20-22
30-30
and what looks like 5 plus minus 6 - the 6 is not fully legible so I am guessing and the plus minus is the plus and minus on top of each other.
I know I need to micrometer up the bearings, but was interested in what these markings meant.
Any ideas?
Thanks viiking
