Steve makes a good point about putting it in anyway and not worrying about for years.
Heinz Kegler and I removed my spindle to take off the swing arm about 10 years ago.
Heinz said the swing arm at the point it meets the spindle rotates only a very small amount up and up.
In theory, the original "oil lite" bushings would slowly release that oil for some lube.
Heinz felt that if the spindle was put back into the cradle with a light smear of an anti-galling compound, that
would be sufficient to give a cushion between spindle and cradle, and he also felt that any lube of almost any weight was unlikely to get down those tiny 1/16 inch holes in the spindle anyway, and in fact that regular 40 weight oil was a better choice than the factor stated 140.
He said it was a stupid idea, and that the entire exercise of injecting oil in the spindle in the hopes it would migrate down those holes resulted in 95% of the oil finding its way out the ends and dribbling out.
