Rebuilding a Meyer E-47 Pump - Step by Step

Page - 7

Here we removed the Motor from the Pump. You can see some rust on the shaft. It can be cleaned off with a Scotchbrite pad, or extremely fine sandpaper. Care must be exercised to not scratch the highly polished part of the shaft.

The highly polished part of the shaft rides on the bronze bushing. The motor has no bearings, only bronze bushings. Be careful when cleaning this, as bronze is porous, and you don't want to degrease it. In fact after cleaning it with solvent on a rag, you should let the end cap soak in light motor oil over night, so the bronze can soak up more oil.

Here the Motor Top Cap has been removed, and you can see the Carbon Brushes, and the motor Armature. You can tell by the heavy corrosion on the motor screws that moisture was getting into the motor.

Here is a closer look at the Carbon Brushes and Springs.

And here is a tool we made to use when putting the motor back together. It allows you to hold the carbon brushes in place while putting the cap back onto the motor Shaft. We put a single drop of light machine oil on the bronze bushing in the Motor Cap.
