6. Remove valve block (7).
7. Remove gear housing. Make sure rear bearing block
remains on drive and idler gear shafts.
8. Remove rear bearing block from drive and idler gear
shafts.
9. Before removing gear set, apply marking dye to mat-
ing teeth to retain "timing". Motor efficiency may be af-
fected if the teeth are not installed in the same position
during reassembly.
10. Remove idler gear.
11. Remove drive gear and shaft slowly until drive end
is through shaft seal.
12. Remove front bearing block.
13. Wash all parts in cleaning solvent. Check all parts for
burrs, scoring, nicks and other damage. If gears, hous-
ing or bearing blocks are damaged or severely worn, en-
tire motor should be replaced.
Seal Replacement (Motor Disassembled)
1. Put flange (3) on a clean, flat surface with shaft seal
(2) facing up. Remove retaining ring (1).
2. Remove shaft seal, being careful not to scratch seal
bore in flange. Scratches in seal bore could cause leak-
age. Make sure seal bore is clean.
3. Put new shaft seal (part number side up) in seal bore
and press seal into bore until seal reaches bottom of
bore. Uniform pressure must be applied to face of shaft
seal to prevent damage to seal and misalignment in seal
bore.
4. Install retaining ring with sharp edge facing out.
E–seal Replacement
1. Put bearing block on a clean, flat surface with E–seal
(4) facing up. Remove E–seal. Clean E–seal groove.
2. Apply a light coating of grease or petroleum jelly in E–
seal groove and on back (flat) side of new E–seal. Put
E–seal, flat side up, into groove in bearing block.
3. Repeat for other bearing block.

O–ring Replacement
1. Remove dowel pins (6) and O–rings (5) from gear
housing. Clean O–ring grooves.
2. Apply a light coating of grease or petroleum jelly to O–
ring grooves in gear housing and install new O–rings in
each groove.
Reassembly
1. Put flange (3) on a flat surface with shaft seal facing
down. Make sure back side of flange is free of contami-
nation.
2. Put front bearing block, seal side down, on flange.
3. Apply a light coating of oil to exposed face of bearing
block. Put tape or seal protector tool (TOR4072) over
splined end of drive shaft. Insert drive shaft through
bearing block and shaft seal.
4. Put idler gear on bearing block. Apply a light coating
of oil to back face of drive and idler gears.
5. Put rear bearing block, seal side up, on drive and idler
gear shafts.
6. Install the two front dowel pins in the flange.
7. Carefully install gear housing over rear bearing block
and slide gear housing down over the gears and front
bearing block. Make sure the markings put on the flange
and housing earlier line up.
8. The rear bearing block should sit just below back face
of gear housing. If bearing block sits higher that rear face
of housing, remove gear housing and check that E–seal
or O–ring did not shift out of place during assembly.
9. Install remaining two dowel pins in rear of gear hous-
ing, then put end cover on back of motor.
10. After motor has been assembled, tighten capscrews
by hand. Tighten the capscrews evenly in a crossing
pattern to a torque of 40 – 45 ft–lb.
11. Put a small amount of hydraulic oil in port on motor
and rotate driveshaft one revolution. Protect the shaft if
using a pliers. If drive shaft binds, disassemble motor
and repeat assembly process.
