XE Megajolt Trigger Wheel?
What have you XE chaps done regarding the crank pulley and trigger wheel for megajolt?
Standard pulley?
Alloy pulley?
Multigroove?
Single V?
Welded trigger wheel on?
Bolted on?

I have been thinking about this to I can,t weld it on the front pulley as it is multigroved and will damage rubber so I thought. If I take the six
bolts out that mount the inner and outer pully together make a boss to sit on the front and use longer bolts to hold it all together this will keep
the trigger whee labout 25mm from groved pulley if that makes sense. One of my concerns is would this cause the pulley to be out of balance and cause
issues later on any advise welcome. Kev

ex crank pulley , trigger wheel
i had my grooved pulley machined down to a step to allow the trigger wheel to slip on
was alittle concerned about welding but just put 4 small tacks on and cooled after each tack
seems to have worked a treat
when you start this journey
you think it will be done in " no " time but then " no " turns into a " bloody " long time

i've got an XEV engine, with a multi groove pulley which is attached to the timing belt pulley with 4x M8 bolts, all i did was get a special
trigger cut to my design, with 4 holes for the bolts to pass through, and a few extra holes to allow water and stuff out.
its good, but doesn't quite centre itself perfectly, so i will get about 1mm band removed by lathe to the pulley sits in this band to help
centre everything.
also, i have the sensor pointing at the back of the trigger, helps keep the timing right, even if the trigger isn't perfectly centred
 
Description
you can sort of get the idea about the bolts here
 
Description
any use? or is there something i've done really wrong that needs pointing out? lol
my only worry is if the belt snaps for any reason, i lose my crank sensor, but how likely is that going to happen?

I did think of using the original double V pulley and attach a trigger wheel to it, either careful welding or bolting, but the pulley will have a
redundant V where the power steering belt was and be unnecessary.
That could be altered to be the trigger wheel I suppose.....
Or get a lighter alloy pulley and bolt a trigger wheel on......in which case I've answered my own question.
Just wondered what other XE users have used.

Has anyone used a double V pulley and converted the redundant front V into a trigger wheel?
How thick do the teeth need to be for megajolt?
