11-23. REMOVING SLIP RINGS. (Refer to Figure 11-16.)
a.
Unsolder the rotor coil (field) leads from the solder lugs.
b. Remove grease retainer with a pair of diagonal pliers.
c.
Cut through the copper of both slip rings at opposite points (180° apart) with a chisel.
d. Break the insulator and remove the ring.
e.
Clean away any dirt and all particles of the old ring.
f.
Scrape the face of the fan to be sure it is smooth.
g. Clean the shaft surface on the area that contacts the inner diameter of the ring and also the ends of the
rotor coil leads.
11-24. INSTALLATION OF SLIP RINGS. (Refer to Figures 11-17 and 11-18.)
1. Position the slip ring on the rotor shaft so the solder lugs align with the rotor coil leads.
2. Place assembly tool C-3900 over rotor shaft and slip ring.
3. Position assembly in an arbor press and press the slip ring on the shaft until it bottoms on the rotor fan.
4. Coil the insulated brush slip ring lead around the solder lug and solder securely with rosin core solder.
5. Coil the ground brush ring field lead around the solder lug located 180° from the slip ring lug and
solder with rosin core solder.
6. Test slip rings for ground with 110-volt test lamp by touching one test probe to rotor pole shoe and
remaining probe to slip rings. Test lamp should not light. If lamp lights, slip rings are shorted to
ground, possible due to grounding insulated field lead when installing slip ring. If rotor is not
grounded, lightly clean up slip ring surface with -00- sandpaper and assemble alternator.
