Laser cut Triumph EDIS timing wheels


Andy Borris

Recommended Posts

I  have sourced a 36-1 timing wheel which will fit in-between the crankshaft damper and the crankshaft pulley.

It's cut from 2 mm thick sheet steel and is based on proven design as used on MGBs (they have their uses!).

It's not a universal fit type, but with a center bore specific to Triumph 6 cylinders. It will have 36 teeth, you'll need to remove one tooth, this makes it slightly easier to install because you can remove the tooth in relation to your sensor position after fitting.

One small machine screw thru the pulley will lock it in place.

Fitting a thin timing wheel between the damper and the crankshaft pulley means the steering and water pumps belts run without deflection.

The bracket needed to support the sensor can be smaller with less chance of bracket vibration affecting the sensor.

No need to buy an electric fan, it'll work with the standard one.

I know it'll will work with an EDIS system, but you'll need to check if you're using a different system, I'm only sure about the EDIS because that's the one I'm using!

I'm also selling at cost, £11.50 and P&P, almost half price compared to the universal type from here http://trigger-wheels.com/store/contents/en-uk/d5.html !

Please email andyborris@yahoo.com if interested.

I take it this is for a Megajolt conversion for the 6-pot?  If so, what else is needed?  You mention that one of the 36 teeth need removing. Which one and how would someone do that?

I'm interested in the Megajolt conversion but I'd really like a complete off the shelf package ready to fit by my local garage or perhaps a technically knowledgeable friend.   I thought I could get this from Trigger Wheels, but looking at their web-site, all I see is a range of components and assemblies for sale.  

Is it time for one of the Triumph specialists to offer a complete package 'ready to go' for people who don't want to/don't have the knowledge to play with their cars?  

(apologies for slight thread drift)

Nick, fitting it is only one part. Programming the unit to suit your car is the other. I doubt a company will want to sell a "bolt-on kit ready to go " because the owner may programme it up wrong and damage the engine. Thiugh I suppose if somebody sold the kit fitted and set uop that would be a different matter.

For simplicity have you thought about the 123 distributor? That is plug and play.

But if you want Megajolt, then the list of parts is pretyy simple.
Megajolt unit (MAP sensor if on our cars is probably best)
Edis 4/6 with plug and wiring
Sensor
36-1 triggerwheel
screened cable for the sensor connections
coilpack and plug leads

Plus a laptop and connection lead.

Thats about it. Honest. I am an electronics numpty and bought an assembled unit, soldered up a loom and downloaded a map off a website to suit my engine. Ran just about straight off (fuse in fuseholder helped :B)

Does anyone offer this service?  I haven't seen any Triumph specialist do this as yet, unless I'm looking at the wrong suppliers.

Thanks for for the help Clive but to some (like me) the expressions "soldered up a loom" and "downloaded a map for my particular engine" are just another set of unknown issues and potential problems. If I bought the bits listed I wouldn't know where to start putting them together!    

I admire you guys who do a lot of the work yourselves but the fact is some people just aren't practical by nature, which perhaps explains why I'm an Accountant and play with numbers all day!   Good though the club support and Triumph specialists are, there does seem to be a gap in the market for someone to offer supply and installation of the newer technology into our cars for those that want it.  

Meanwhile, I'll carry on mastering my mechanical engineering skills. I did manage to strip down my GT6 front suspension this morning so things are looking up!   :)

A pair of tin snips will remove the spare tooth, just thought it'd make it easier to install, because the tooth isn't removed till after everything is fitted, it won't matter where the sensor is in relation to the wheel.

As seen in the photo, you can bend the teeth over, I'm going to do this, but the opposite way. With a touch of white paint on the original timing mark.

The picture shows the type of wheel, not the actual wheel, I designed it to fit between the crank balance weight and the crank pulley, if like me you have power steering, mounting the wheel on the very end of the crank means using a very long bracket, with more chance of the bracket vibrating.

Unless you build it from girders!

The buyers so far list:

Andy Borris 1
Colin Wake 2
John Davis  1
Andy Brady  1
Richard B     2

I have based the price on 20 units, no doubt I can get 7 wheels cut, but not at this price 10 wheels are just over £15, still cheaper then the ones from triggerwheels.com.

I've got 30 days to place the order at this price, plus VAT increases at the end of the year!

No, not stainless.

I thought stainless steel wasn't magnetic? Or is just some types?

And these wheels may not fit your V8!

Hi Andy the ones that trigger wheels sales are a magnetic stainless steel. And the ones you are doing can fit my crank pully with a bit of !!
Any way good luck with them allways up for saving a pound or two

I think what Andy is getting at is that the 36-1 pattern may not suit a V8 engine, I could be wrong.
Needs looking into.

Any 36-1 will suit any engine you just have to have the room to put on and the crank sensor in the right place for the engine your running ie 4-6-8cyl

Ferritic stainless steels contain iron & chromium & are magnetic eg grades 409 & 430.
Austenitic stainless steels contain iron, chromium & nickel & are more corrosion resistant, more expensive & non-magnetic eg grades 304 & 316. (304 is also known as 18/8, 18% chrome, 8% nickel)

Yep the Ford EDIS system supports 4 6 & 8 cylinder engines.

I think you can even do a 12 cylinder, you use 2 x 6 cylinder setups  :-/
