6. Just as earlier if the stone is used parts it is used on
MUST be washed and dried . Make certain bushings are flush
with castings and there are NO burrs on the top ID of
bushings.
(figure 31). Bushing must not be higher than face
of casting, Motor will not bolt together correctly if it does.
7. Check to make certain that the dowel pins are in place in
any new castings and that the location corresponds with the
mating casting. Before inserting any dowel pins check to
make certain holes are clean, the top of the holes do not have
burrs. To insert dowels hold the dowel in alignment with the
hole. Gently start the pin into the hole straight, tap lightly with
a soft hammer until dowel is seated into hole.
(figure 32).
Note as shown, dowel pins have holes in the center, this
is for the retaining bolts to go through.
8. Remove the shaft end cover from the vice and turn it over
180° and re-insert it into the vise with the splined side up
(figure
34). Before inserting the new lip seal into the shaft
end cover. Coat the outer edge of the lip seal with Permatex
Aviation Form-A- Gasket™ No. 3 non-hardening sealant or
equivalent (figure 33). With the metal side of the seal up,
press it into the mounting flange side of the shaft end cover
with an arbor press and bar
(see recommended tools list) .
Be careful not to damage the lip seal. Press the lip seal in
until flush with the recess, wipe off excess sealant.
9. Install the Seal Retaining Cup (figure 15) , guide the Seal
Retaining Cup into the recess in the shaft end cover. This
is a light press fit and can be pressed in with the arbor press
or it can be lightly tapped into the bore.
DO NOT use
excessive force to insert retaining cup, if it will not go with light
force check for size error or other reason. Forcing an over
size bearing in will damage bearing and casting
(figure 15 &
44).
