The famous 36-1 trigger wheel for external use with either megasquirt, megajolt and/or EDIS VR sensor, and designed specifically for the VW crank pulleys. (serpentine or V-belt)
It comes in a classy and subtle black finish.
It is alway a hassle to get proper concentricity, and a good set up for VW specific applications.
Most of the times a Ford trigger wheel, or a generic trigger wheel need to be modified, and turned true, afterwards.
This solution comes from our own need, and was developped for our race cars.
This trigger wheel solution, even makes provision to have, or add, a power steering pulley to the damper / crank pulley, without any modifications !
trigger wheel is precisely laser cut, and then a pilot diameter is CNC
machined to very tight tolerance, in order to fit directly in the recess
of the Serpentine crank pulley; this mating of the pilot & recess,
garanties concentricity of the trigger wheel, to the puley. Be sure that
your pulley has an internal bore of 4.552" for this application. (this
is the bore we measured from 5 different pulleys we have on the shelf)
radii slots are precisely cut to match the pulley's avaialble material
to accept the needed M5X0.8 threads. 12.9 graded bolts. These button
head graded bolts, are supplied with the trigger wheel.
install, clamp the trigger wheel on your pulley, in order to have them
concentric (the recess of the pulley will locate on the trigger wheel's
machined step), and then center punch the aluminum in your crank pulley.
Be shure to have the missing tooth alignement marked in relation to your
TDC, and sensor position, prior to making the threaded holes. This will
allow to align the holes that you will need to tap in your pulley /
damper. Then tap 4 holes M5X0.8 about 3/8" deep (thread depth)
The size drill for tapping M5X0.8 is 4.2mm or a #19 drill
This listing is for the trigger wheel only, no pulley is supplied.
we can supply a pre-owned pulley, already drilled and tapped contact us for more details.
I can supply seprpentine, or V belt, as needed.
can also supply the trigger wheel solution for the 8V "V-belt" damper
at the same price; the pilot bore is not the same, but I have pulleys in
stock to take the dimensions / mock-up, in order to machine them for
the 8V application, please contact us for more details.
I also have the VR sensor bracket for the PL / 9A , and ABA blocks, and both go hand in hand, for a complete solution
