Sometime between 1959 and 1963 the factory noticed the Torrington bearing on the gear end of the clutch gear was taking all the load and the second bushing was removed.
The picture shows the bushing that is used on all years.
The bushing has a spiral groove to trap dirt and transport oil.

 The Iron Sportster mainshaft is a triumph of engineering. The general design has sustained from 1952 to 1984. There were teething problems in the early K-model, but they were all cured by 1957 with the introduction of the Sportster.
There are two bronze bushings in early clutch gears. Sometime between the 1959 and 1963 parts books, Harley took the one out near the Torrington bearing. |
