(2) Apply liberal quantity of petroleum jelly to
countershaft front bearing. Then insert bearing in
front housing race (Fig. 134). Large diameter side
of bearing cage goes toward countershaft (Fig.
135). Small diameter side goes toward bearing
race in housing.
(3) Reach into countershaft front bearing with fin­
ger, and push each bearing roller outward against
race. Then apply extra petroleum jelly to hold rollers
in place. This avoids having rollers becoming dis­
placed during housing installation. This will result i n
misalignment between bearing and countershaft
bearing hub.
(4) Install input shaft bearing in front housing
bore (Fig. 135). Use plastic mallet to seat bearing.
Bearing goes in from front side of housing only.
