REPAIR KIT INSTALLATION
Caution: Do not remove the protective paper tube from the new flange assembly.
DISASSEMBLY:
1. Wipe the motor with a clean cloth to remove dirt which could contaminate
the motor.
2. Note port locations then remove hoses and external fittings.
3. Mark the motor section joints to indicate orientation of the motor
components.
4. Remove (4) motor assembly cap screws. Motors with hex head cap
screws require a 17 mm socket. Motors with socket head cap screws
require a 9.5 mm or 3/8" hex key wrench.
5. Set motor on rear cover with shaft pointing up.
6. Remove front motor flange by pressing thumbs against shaft end while
pulling up with fingers behind flange ears. Take care to not disturb the
other motor components.
7. Remove the housing seal O-ring and discard the old flange assembly.
Inspect the motor shaft for grooving or scoring. Moderate to severe
damage in the sealing area may prevent proper sealing and require motor
replacement.
