I would like to install a trigger wheel in order to move to Megajolt this winter.
But I struggle to undersatnd where to install the wheel on the damper/pulley serpentine unit.
Does it get sandwiched between the vibration damper and the pulley?
--> This means shifting the belt outwards by the thickness of the wheel.
Does it go in place of the skirt on the timing cover side?
--> Which means machining of the skirt and attach the wheel with extra nuts.

What's the collective wisdom here?

I did run a search but couldn't find any definite answer and pictures of final assembly.
I don't have any balancing weight wedged in the skirt as well.
Regards
Philippe

Have a look here on the Lloyd Specialist Development website at the installation manual.

Or a really nice set up is the John Eales damper, pulley and trigger wheel, along with a nice sensor holder.

So, there are two possibilities:
- If belt alignment allows it, the trigger wheel can be sandwiched between pulley and vibration damper.
- If not, trigger wheel can be installed between damper and skirt.
The later solution is a bit more obscure to me since I was under the impression that the skirt was welded to the damper inner ring. But apparently not!

Unfortunately, my engine is now dismantled and I can't verify the belt alignment.
It will have to be done upon re-assembly.

Pistonheads as useful as ever!
Cheers guys.

The crank pulley is in three parts.
The main part is the casting with the timing marks marked around the rim.
second part is the belt pulley.
Third is a st shield type thing on the back.

Get one of these.

Which cost me £17 a few years back. Its from a Ford Transit.

Mount it between the back of the main casting and the st shield with the trigger fingers pointing forwards. It is a nice snug fit over the part of the pulley where the timing marks are.
Because it is mounted behind the main casting it does not effect the belt alignment. Also it is only about 1.5mm thick pressed steel so the st shield still clears the timing case.

The guys who fit these on 4x4s fill between the fingers with PU sealant so that mud and stones cannot get between the fingers and jam against the sensor.
