DESCRIPTION 

The Edelbrock Qwikdata Shaft Speed Sensor Kit allows users
of the Qwikdata data aquisition system or other data

aquisition systems to mount up to 4 magnets in an aluminum
ring to the rear end pinion yoke on a Ford 9” housing. 

Part #91195 will mount to most standard Ford 9” rear
housings with a 1.875” diameter pinion yoke.  Part #91196
will fit 2.187” diameter, 35 spline yokes.

Installation Procedure

Note:  

Refer to Figure 1 below for reference on all steps.

1. Install the number of magnets you require for your data

aquisition system into the ring assembly.

2. The magnets are to be seated against the shoulder (towards

the outside diameter of the ring), then glued with an adhesive
such as epoxy, RTV silicone, hot glue, etc.  

(Note: 

Some

computers are sensitive to the magnet’s north and south

poles.  Install magnets per requirements for your data
aquisition system.)

3. Install the ring halves around the pinion coupler and tighten

the 10-32 x 3/4” cap screws tightly.  The beveled edge of the

Kit Contents:

1 - Two-Piece Aluminum Mounting Ring
2 - 10-32 x 3/4” Cap Screws

4 - Magnets
1 - Sensor Switch Bracket

1 - Sensor Switch

Tighten so that the

gaps are even

Use a washer .060”-.080” thick to prevent

interference with the pinion support radius

Grip Diameter

Be sure the magnets are

seated against the outside

shoulder of the ring

Beveled edge should

face Pinion U-Joint

Set gap at .060”-.100” for

Qwikdata use

OR

Set gap per data aquisition system

per manufacturer’s instructions

Note:  Some multi-magnet sensors are pole-sensitive

and must be installed in c/- sequence.

FIGURE 1

Fill cavities with

epoxy or silicone

to secure magnets

inside of the ring should face the pinion U-joint.  The gap on
each side of the ring should be even to ensure correct timing
on multiple magnet use.

4. Attach the Sensor Switch Bracket to a bolt or stud on the rear

end housing as shown in Figure 1.  Attach Sensor Switch and

adjust gap to .060”-.100” for Qwikdata use, or to your data
aquisition system specification.

Note: 

Periodically, make sure the magnets and mounting ring

are secure.

Caution: 

Excessive heat can cause the magnets to lose

power.
