6. Install a new sprocket shaft seal following instructions in the H-D service manual.
Install the Compu-Fire flanged seal spacer. NOTE: Lubricate the seal and the seal
surface of spacer with motor oil prior to installation.
7. Install the Compu-Fire 3 Phase stator using new fasteners (H-D Part no. 2720).
Torque the mounting screws to the specs in the service manual. NOTE: Make sure
the cable from the stator is routed so it does not pinch between the stator and
the case, and so that the rotor does not rub it. Install the stator plug retainer.
CAUTION! The Compu-Fire 3 Phase alternating rotor must only be used with the 3 Phase stator
supplied in the kit. Do not use the 3 Phase rotor with any other 40 amp wide stators. Do not use
the 3 Phase rotor as a replacement for Compu-Fire 40 amp charging systems part no. 55515,
55550, or 55555.
WARNING! The Compu-Fire 3 Phase rotor uses extremely strong magnets that may be
damaged if the rotor is placed near any metal parts, tools, or hardware in the work area.
WARNING! Special tools are required in the installation of the rotor. The Compu-Fire 3 Phase
rotor uses extremely strong magnets that may cause the installer to lose hold of the rotor during
installation. Severe injury may occur if the installer’s fingers become pinched between the rotor
and the engine case or the stator during installation. Use H-D tool P/N 41771 or Jim’s tool P/N
758-147 when installing the rotor.
8. Install the rotor on the crank shaft using H-D installation tool part no. 41771. NOTE:
The rotor will be vented in closed primary systems to allow additional cooling of the
stator. Open primary systems will use an unvented rotor. Refer to Figure 1.
COMPONENTS SUPPLIED IN THE COMPU-FIRE 3 PHASE SYSTEM
1. Large Flanged Seal Spacer
2. Alternating rotor (vented shown for wet primary systems)
3. Spacer washer (2.81 in. O.D. x .219 in. thick) except Softail/Dyna
