Shaft Seal Removal
1. Remove reel motor (see Reel Motor Removal and
Installation).
2. Plug ports and wash exterior of motor with cleaning
solvent. Make sure parts and work area are clean.
3. Remove retaining ring from motor (Fig. 90).
IMPORTANT: Do not try to pry the seal out of the mo-
tor. This usually damages the shaft seal bore and
mounting hub area so oil will leak past the seal.
Note: Seal may also be removed by punching two
holes in face of seal 180_ apart, installing metal screws
and pulling seal out by grasping the screws.
4. Install threaded metal O-ring seal plugs in the two (2)
pressure ports on the motor or put metal threaded caps
on the fittings in these ports.
5. With motor shaft pointed away from you into a clean
five (5) gallon container, attach a hydraulic load (hand
pump) or compressed air to the case drain port.
6. With the motor shaft pointed away from you into a
clean five (5) gallon container, gradually apply pressure
to the case drain port. The seal should come out of the
motor seal cavity.
7. Remove and discard shaft seal and spacer.
Shaft Seal Installation
1. Clean seal bore and shaft on motor so it is free of any
foreign material.
2. Install a new spacer on motor shaft.
3. Put seal protector tool on motor shaft (Fig. 92) or ap-
ply thin plastic or tape on the shaft to protect the seal
from damage.
4. Apply "Permatex No. 2" or equivalent to outside di-
ameter of new seal.
5. Apply grease or petroleum jelly to inside diameter of
new shaft seal.
6. Use seal installation tool to install new shaft seal.
Make sure seal is installed square with the seal bore
(Fig. 92).
Disassembly
1. Plug ports and wash exterior of motor with cleaning
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. Remove shaft seal (see Shaft Seal Removal).
3. Draw a line across the seam areas on the motor case
with a scribe or marker to ensure proper reassembly.
4. Remove four socket head cap screws (Fig. 96).
5. 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 dis-
engage gear mesh.
6. Before removing gear set, apply marking dye to mat-
ing teeth to retain "timing". Pump efficiency may be af-
fected if the teeth are not installed in the same position
during reassembly.
IMPORTANT: To prevent damage to load plates dur-
ing motor operation, do not mark gears with a punch
or scribe.
7. Be careful when disassembling. The needle bear-
ings may be of the loose grease retained type. Pack
these with general purpose grease to retain them for re-
assembly It is recommended NOT to remove the bear-
ing races from the cover and body.

shaft seal, and spacer (Items 8, 13, 12 and 11). These
items are available in a repair kit.

2. Replace gears as a set if excessively scored or worn.
Replace load plate if worn or scored.
Assembly
1. Apply grease or petroleum jelly to load plate assem-
bly and install in body. Insert gear set into body, main-
taining the original timing and locations.
