Installing new Speed/Reference Sensor Bracket - advice

[Tidybuoy]

I accidently broke the speed & reference sensor bracket when doing some other work.

I'm getting ready to install the new bracket and I'm following the advice on Clark's Grarage where he suggests gluing an .8mm washer to the bottom of the sensor, and adjusting the bracket to this measurement. The 944 shop manual has the same directions.

My questions:

1) any recommendation on the type of glue I should used. I just thought I'd ask since I don't have any and will have to go buy something.

2) I thought there were some marks or studs on the flywheel that the sensors are triggered by, do I need to have these lined up in the sensor hole before doing this procedure? I've been turning the engine looking for these but I don't seem to see anything.

3) How in the heck am I going t measure a washer for .8mm thickness?

Thanks, in advance for any advice.

Use rubber cement.

There are set screws on the flywheel for the forward sensor to read. The rear sensor reads off the teeth on the starter ring gear.

A generic washer is about the right thickness usually. The better method for doing this is to slot the bell housing so the sensors and bracket can be installed and gapped prior to putting the bell housing back on.

Cut out the center portion like this..



So you can gap the sensors from under the car. Note, the .8mm clearance needs to be measured from the speed sensor to ring gear teeth (rear most sensor). In the picture i have a gapping tool specifically for this, but you can achieve the same thing with the right combo of feeler gauges.

Don't forget to put anti-seize on the speed and reference sensors for ease of removal later down the road.

Thanks for the tips.

The photos help me to understand what that sensor is sensing...no wonder I couldn't see the studs.

I had the torque tube off and when I was lining it all back up...that's when I hit the sensor bracket very slightly and it broke.

Thanks.....Vern
