Slip Ring End Frame: Installation
- Install terminal insulator to the outside of the slip ring end frame.
- Install BAT terminal to the rectifier bridge with a washer and nut.
- Install rectifier bridge into the end frame.
- Install capacitor. Make sure the side with the insulator material is placed against the end frame (ground).
- Install two bolts through the rectifier bridge.
- Install two insulated screws through the rectifier bridge. If the brush holder, regulator, or connector has been replaced, connect it by crimping the connectors to the other components. Solder the connection using as little heat as possible to avoid heat damage to the regulator. See Figure.
- Install brushes into the brush holder.
- If the brushes are being reused, be sure they are clean. Wipe them with a clean, dry cloth.
- Retract the brushes in the holder.
- Retain the retracted brushes with a retaining pin.
- Make sure the pin extends through the end frame when the brush holder is in place. After the rotor and drive end frame are installed, the pin will be pulled out, allowing the brushes to contact the slip rings.
- Install brush holder, regulator and connector assembly into the end frame. See Figure. The metal side of the capacitor strap should rest against the regulator connection.
- Install one bolt into the brush holder. If a brush holder with locator bosses is being replaced with a holder without locators, make sure to align the brush holder assembly and hold it with your fingers while tightening the brush holder attaching screw.
- Install two insulated screws through the regulator connector.
- Install stator into the end frame, aligning the three stator leads to the three rectifier bridge terminals. See Fig 1.

- Install three rectifier bridge nuts. Tighten the nuts securely.
