! CAUTION
The pump must be separated from the magnet coupling if further disassembly is required. Follow
the instructions below.
Use jack screws to disassemble models 6200 Series pumps. Jack screw kits are available as part
number 2CMG 558 for models 6202, 6203 and 6204 and part number 5CMG 558 for models 6205
and 6206.
DO NOT PLACE HAND OR FINGERS BETWEEN THE HOUSING AND ADAPTER. The magnets
are extremely strong and will attract all metallic objects and can be the source of pinch points. Do
not wear watches or other metallic jewelry when working with magnets. See warning on Page 2.
Failure to follow proper procedures or use appropriate tools could result in injury to you or damage
to either personal property or the pump.
6. Remove the screws that attach the bearing housing / outer magnet sub-assembly to the
adapter.
7. Use jack screws to separate the inner and outer magnets:
a. Place (3) guide studs into adapter at screw locations and hand tighten.
b. Place (1) threaded stud into bearing housing and slowly turn the threaded stud to jack the
bearing housing / outer magnet sub-assembly out.
c. Continue turning the threaded stud until separation of the inner and outer magnet is
complete.
8. Remove pump bracket, rotor and canister sub-assembly from adapter.
9. Remove the canister from the bracket. The canister will probably contain residual pumping
fluid. Use care when removing, making sure to pull the canister straight off.
10. Remove the back retaining ring and remove the inner magnet.
11. Set magnet down on a clean, non-magnetic surface, inspect the magnet sleeve for evidence of
damage or excessive wear and cover with a cloth to prevent contamination.
12. Remove the front retaining ring (if equipped). Check the shaft O.D. for any burrs and remove to
prevent damage to the bracket bushings.
13. Remove the rotor from the bracket.
14. The back face of the rotor and the bracket face should be inspected for any deep scratches or
wear. Inspect the bushing in the bracket for wear.
15. Do not remove the o-ring from the bracket unless it is worn or damaged and needs replacement.
