JE Rv8 Crank Trigger

[Graham]

Does anyone have a pic of one of these fitted to an engine, so I can work out if there is room to fit on on mine


cheers Graham

I imagine it fits behind the crank pulley or in front. Either way it won't be very thick. Expect it to be 5mm thick and similar diameter.

Mine (from JE) is about 120mm diameter and about 10mm thick, but I don't suppose they are all like that. I fitted it behind the crank damper and put the VR sensor on a bracket on the front of the water pump (pre-serp).

[stevieturbo]

The one I used was about 5" diam, and 3-4mm thick. I fitted it to the rear/inside of the crank pulley, and made a bracket for the crank sensor.

Cheers I've got a pic of the components, but is the sensor bracket fitted to the left or the right of the engine (looking at the front of the engine standing at the front of the car...)

if its the right im buggered as my dry sump pump mounts there...

oh yes its a serp front cover
cheers

I don't have practical experience of installing one of these but it seems to me that so long as the transducer can sense the teeth and the missing tooth/teeth can be positioned to correspond with #1 TDC then that's all you need. It could be in front, behind, Left right, top, bottom, or even on the edge.
Sits back and waits to be corrected by someone who's actually done it

Leo, yep thats,about it, although you need to take into account movment due to vibration etc. What i was hoping for was to use the JE kit as a bolt on, as its solid mounted and means no fabrication.. provided it'll fit. That why i was hoping someone might have used the je kit and have a pic of it.

im quite restricted, as i have a dry sump pump mounted on one side and the drive for this is on the front of the pully.


Cheers Graham..

Seem to recall my supplied pick off bracket needed serious beefing up to stop erractic (vibration) readings. I'm sure Paul at Austec used a great lump of angle iron to support it in the end .
The trigger wheel was one supplied by Mark Adams who I think gets them made up to his spec by a man local to him.

unfortunetly it is mounted on the right hand side looking from the front, there are only two bolts that side apart from the long water pump ones and thats where the bracket fits!

Then just move the position of the sensor so it clears everything, and rotate the trigger wheel to suit.

My sensor pickup also using a Ford sensor wasnt exactly rock solid, and I never experienced any problems with my DTA ecu.
Even my engine was bolted solid into the car.

You can mount it at about 10 0'clock on the other side from memory without any issues

[GreenV8S]

My first mounting bracket was made from folded up 2mm aluminium sheet and wasn't stiff enough, I started getting misreadings and eventually the sensor ended up clipping the wheel. The new one is made from 5mm sheet and is much stiffer, I've got a tell-tail on the end of the sensor to see if it moves and there's no sign of it going anywhere.

Just mounted a £13 ford 36-1 wheel onto a serp pulley - quite straightforward.
