MSD Rotor, PN 8467
Fits MSD Distributors with Caps PN 8433,
PN 8431 and other GM Window Style Caps
Parts Included:
1 – Rotor, PN 8467

iMPOrTanT: There are two different length screws supplied with this rotor. It is important to determine
which screws are correct for your application due to clearance of the magnetic pickup.
Remove the cap and rotor and note the rotor screw retainer that is installed on the bottom of the
advance plate (Figure 1). There are two styles used; one is a Screw Retainer, the other is a Retainer with
a Nut. The Retainer accepts the shorter 5/8” screw while the Nut version accepts the 3/4” screw.
Once the rotor screw length is determined, install the rotor being
sure the round and square aligning pegs are lined up correctly. Install
the Belleville washers with the dome facing up on the screws and
tighten the rotor (Figure 2). Install the cap and plug wires.
