Re: Generator blues
The bushing must be an oilite bushing. That is a pressed grainy
material that allows the oil to saturate in it. These bushings need
to reamed with a very sharp reamer so the material is not smeared
which closes the pours. The clearance is VERY important. If it is a
.500 shaft it should be reamed with a .505 to .507 reamer. Oil from
the bushing forms an oil film which the shaft runs on. The shaft
never touches the bushing. Properly fitted and oiled a shaft or bushing
very rarely fails. You want engine oil to lube the bushing not a very
thin oil. G.M.
