away from the end bell.
CAUTION
DO NOT allow the gear cluster (9) to fall when re-
moving the drive housing (2). It is easily damaged if
dropped. The cluster may stay engaged in either
the front end bell or the drive housing.
DO NOT lose the thrust balls (1 0) located at each
end of the gear cluster (9) or allow them to fall be-
tween gears. The balls, which are heavily covered

not removed, the balls will seriously damage the
drive housing. If the balls are not in place, the bear-
ings will wear prematurely.
