I'm refurbishing a circa 1960 AMC gearbox for a Matchless G80 road bike. Overall the g/box looks good, light corrosion from moisture, no indication of broken gears, nor hard use.
Measuring the main shaft, I find approximately 0.004" TIR (Total Indicated Run-out), measured at the center of the shaft. The intended use is occasional day rides, no competition use.
What is acceptable TIR on this component?
