Reel Motor Shaft Seal Replacement
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 snap ring from motor (Fig. 95).
4. Install threaded m
etal 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 drai
n 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.
NOTE: Seal may also be removed b
y punching two
holes in face of seal 180
o
apart, installing metal screws
and pulling seal out by grasping the screws.
IMPORTANT: Do not try to pry the seal out of the
motor. This usually damages the shaft seal bore and
mounting hub area so oil will leak past the seal.
7. Remove and discard shaft seal and spacer.
8. Clean seal bore and shaft on motor so it is free of any
foreign material.
9. Install a new spacer on motor shaft.
10. Put seal protector tool on motor

apply thin plastic or tape on the shaft to protect the seal
from damage.
11. Apply “Permat
ex No. 2” or equivalent to outside
diameter of new seal.
12. Apply grease or petroleum jelly to inside diameter of
new shaft seal.
13. Use seal installation tool to install new shaft seal.
Make sure seal is installed square with the seal bore.
