MOTOR SERVICE & REPAIR
2. Insert the shaft end cover in the vise with the machined
surface up (figure 27) .
3. If the bushings (figure 28) are to be replaced with new
ones. After the old ones have been removed, Inspect the
holes where the new bushing will be pressed in. If there are
burrs or rough edges at the tops of the holes they can be
de-burred by using your finger and emory cloth. Keep the
emory cloth on an angle and only around the top of the bore
(figure 28). Do this to each hole for the bushing that are to
be replaced . IMPORTANT ! Bushing must be pressed in
with an arbor press DO NOT drive them in with a hammer.
4. Note : Steps 5, 6, 7 & 8 apply to Shaft End Cover and
Port End Cover (figure 15 ) Any bushing removed from the
shaft end cover, port end cover or bearing end cover should
be assembled in the drive bores with the grooves to the top
of unit
(12 O'clock) . Assemble the bushings in the driven
bores with the groove to the bottom of the unit (6 O'clock) .
The Grooves refer to the bearing seam (figure 29).
5. Bushings should be pressed into the bores one at a
time, Use the special installation tool (figure 5 Tools recco-
mmended list) and an arbor pres. Be sure that the groove
(or seam) are positioned as stated in step 5 previously . Be
sure to support casting so they are square and level to the
arbor press and the bushings are straight before attempting
to press them in. The bushing must be pressed into the
bores flush with the casting face
(figure 30).

Motor Assembly:
1. Check all the machined surfaces on all Motor components to make certain they are level and free of
scratches. Minor scratches and slight un-level conditions may be fixed by using a Medium Grit Carborundurn
Stone. This must be done equal all the way across the face of the machine surface to keep it level
(figure 26).
ALL part must be cleaned and dried if stone is used it . If deep scratches or excessively un-level the section
needs to be replaced, make certain this is checked before continuing installation of other components. Replace
the parts with machined surfaces if required. Check comp-
onents for wear or damage now before continuing.
