1. Plug ports and wash exterior of motor with mineral
spirits or solvent. Make sure parts and work area are
clean.
IMPORTANT: Extreme caution must be used when
using a vise to avoid distorting any parts.
2. Draw a line across the seam areas on the motor case
with a scribe or marker to ensure proper reassembly.
3. Remove four socket head capscrews.
4. Put your hand on the cover assembly and gently tap
the drive shaft with a soft face hammer to separate the
body from the cover. Be careful not to drop parts or
disengage gear mesh.
5. Before removing gear set, apply marking dye to
mating teeth to retain “timing” when reassembling.
6. Be careful when disassembling. The needle bearings
may be of the loose grease retained type. Pack these
with general purpose grease to retain them for reassem-
bly. It is recommended NOT to remove the bearing races
from the cover and body.
7. Remove and discard the bridging insert, gasket in-
sert, anti-extrusion block, snap ring, shaft seal, spacer,
seal assembly, wear plate and o-ring, (Items 5, 6, 8-11,
14, 15 and 17). These items are available in a repair kit.
8. Clean all parts and check for burrs, scoring,
nicks, etc.
9. Rub mating surfaces of body and cover with 400 grit
or finer sandpaper to remove any Loctite residue. Wash
body and cover to remove abrasive material.
10. Apply grease to bridging insert and put in cover, tab
side down.
11. Apply grease to gasket insert and put in place over
bridging insert.
12. Stone gears if wear plate appears scored. Replace
as set if necessary. Oil the inside of cover and insert the
gear set, maintaining the original timing and locations.
13. Apply grease to wear plate and slip over shafts with
wider cross section next to bridging insert. If the wear
plate is made of steel backed bronze, the bronze side
must face gears.
