Adjustable Two Piece Rotor
(For use in place of PN 8467 Rotor)
Parts Included:

The Adjustable Rotor is for use with MSD Distributors using the PN 8437, PN 8433, PN 8431, PN 84333 or PN
84313 Caps. The two piece Rotor provides up to 40° (+/- 20°) of adjustment to achieve proper rotor phasing.
IDENTIFY ROTOR SCREWS
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. There are two styles used;
one is a threaded base with or without 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 (Figure 1).
Note: It is recommended to install the rotor and check the clearance before reassembling the
distributor.
INSTALLATION
Once the rotor screw length is determined, install the rotor base
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).
