Speedo sender bracket

[chris farrow]

Has anyone got any pics of a speedo sender bracket they have made!! (Sumo)
I have fitted an ETB sender unit with magnets on the daisy wheel, the bracket i made up is fitted to the cross member on the chasis but after a test run there must have been some movement on my diff as the magnets must have caught the sender and bent the fins.
Any help much appreciated.

I haven't got a picture but I doubt that you'll ever get it to work well with the sensor mounted on the chassis, the diff moves about far too much.

If you are ford based then it is fairly easy to knock up an ali bracket that uess the two bolts at the front of the the diff. (The same ones that the pilgrim mounting bracket for the diff uses)

I know that you have an ETB wheel but for the benefit of others heed my words that the pilgim daisy wheel is no good!
I spent ages adjusting my sensor 0.25mm at a time and could not get the speedo to work properly. It would be OK up to a point then just go mental after that. Fit an ETB wheel (15 quid) set the gap to 3mm and it WILL work just fine!

I don't know what the gap should be for an ETB wheel with magnets but I'm sure it is stated in the instructions. Your issue is that the sensor is mounted to the chassis.

If you still stuck and nobody else has posted I'll take a picture tonight.

Thanks very much i shall try a new bracket at the weekend, do you know how accurate the speedo must be for SVA?

Without taking the bracket off (and messing up the speedo) a photo might be tricky. Attached is a diagram of what I did.

Get a bit of stainless sheet and cut out a shape like that shown, then bend back by 90 degrees the little flaps on the side with holes in, then attach it as Pete has said via the same bolt holes as the diff carrier bracket.

Hi Chris
This is the steel bracket I made, and used one of the front lower diff mount bolts to hold it on.

Many Thanks, great pictures

2 things - kit from Pilgrim comes with pattern for bracket ask Robin or Tony they will send one (or me)
secondly magnets are glued to the bolt that secure diff to propshaft - Daisy wheel is a different method of measuring mph

Also worth noting. New speedos (well from Europa anyway) dont need magnets or daisywheels. Ive just fitted one to a friends car using the propshaft bolts with the sensor mounted on the rear of the LT77 box. Also of help is the rear illumination in the sensor. When you connect 12V and move it close to the bolt heads, when the propshaft is being turned and it senses the bolts it lights up!!
Very helpfull.
