Shaft End Play Adjustment
The lower shaft (Fig. 28, Item 10) and upper shaft (16)
should have a very small amount of bearing drag. If the
shaft turns hard, the cap (12) or (22) must be removed
and gaskets (13, 14, or 15) need to be added. If the shaft
has no bearing drag, or has end play, the cap must be
removed and gaskets taken out. The cap must be ad-
justed so the shaft has no end play and only a slight
amount of bearing drag.
