Removing the end bell and tubing
from the cooling water pump head
Install Tubing and Re-Assemble the Cooling Water Pump Head
1. Hold the released end bell with the tubing retainer grooves pointing down.
2. Center the tubing in the right groove and against the first two rollers. Hold the
tubing with your thumb.
3. With the other hand, working counterclockwise, wrap the tubing completely
around the rotor, pushing the tubing into the bell assembly. When the tubing
has wrapped completely around the rotor, hold the second end in place.
4. Position the end bell with the tubing on the end bell in the console. Ensure that
the flat end of the pump drive shaft fits into the slot on the end of the motor
coupler.
5. Replace the two screws (8 - 32 Phillips) that attach the end bells.
Note: If a gap remains between the two end bells after you position them
together, the pump head may pinch or cut the tubing. Rotate the pump shaft
until the gap disappears.
6. After determining that no gap exists between the end bells, tighten the two
screws.
7. Trim the length of the new tubing to reach the cooling water tube fittings.
8. Connect the tubing to the fittings, and replace the wire ties on the fittings. The
kit includes two extra wire ties in case you break or lose one.
9. Replace the left side cover.
10. Plug the power cord connector into the wall receptacle.
11. Turn on the AC Main Switch, located on the rear panel.
