the OEM bolts were never removed when the crank was balanced.

Here are the options for Crank Triggers, they all have there draw backs.

OEM ABA crank mounted wheel.

This was caused by high WHP 9k rpm shifting. The mounting bolts sheared under extreme shock loading on off throttle.
Not typical of OEM street car but high HP racing this can happen.
This happened to me twice before I ditched the OEM setup.

There are a few options for alternative crank triggers.

EURO TDI pulley mounted

034EFI 16v or ABA pully mount kit

Front/rear main seal trigger wheel

Flywheel trigger.

This is the piece i had made to fit behind the 1.8T fluid amper that makes it fit a ABA/ABF hybrid
all i have to do is drill the mounting holes after i determine where to clock it.

this piece fits as close to the front main for strength against high rpm oscillation and the mounting
holes are not adjustable so nothing can move it's position.

If you like this option i can have the trigger wheel made locally $175 Shipped
I machine orders of 3 at a time.

What took out that trigger wheel? I've seen something like that happen before but only when they've been removed and refastened.

 

[REPOMAN]

The OEM bolts sheared.

My new setup fired up on the first pull of the trigger. I am very happy with the results.
:beer::beer:

 

[ABA Scirocco]

There's not normally much stress on those bolts, any thoughts on why they sheared.

 

[REPOMAN]

I believe it was due to HIGH RPM 9k shifting on a 400whp setup.
the repeated shock loading from shifting from full throttle to full throttle
over a 1500mile period. this has happened twice in the same amount of time
which is why we designed our own for duribilty and longevity.

hmmmmmm 250 shipped hmm

this seems to be just the ticket for my aba 16vT audi 4000q build

 

[REPOMAN]

So checked the timing today... Dead on the money.
drives great. i smacked 8krpm a few times on the way home. no issues..
I will be racing it Saturday June 5th if all goes well then yes i will
make more to order for $250 shipped.
Keep in mind this Trigger wheel will align the 1.8T pully for the
ABA accessory setup on a 16V ABA hydrid. I.E. 16v crank timing gear.

[heyfu]

do want very tempting :thumbup:

 

[REPOMAN]

OK well this is the product

and it installed. Some Assembly Required.

Accessory pully alignment

So if you want one it is a 2 week turn around from order to shipment.
they are made to order.

update.
3000 miles daily driving no issues 1 race event 10 passes. all good.

I have ARP rod/ main/ head bolts. H beam rods, JE forged pistons. ect ect.
OEM Forged Crank

Piston and rods

OEM crank trigger bolts sheered

OEM Trigger wheel

New solution, External wheel

This alignes the serpintine belt pully from a 1.8T to a ABA acessory bracket setup using a 16v Crank Timing gear/ 16v head.

so there is no way to achieve this on a 9a with ABA serp setup? :beer:

 

[JettaG60MK2Rider]

there is a way, after hours on the bridgeport and custom mounts for sensor i have it installed. i need to know how this wheel is timed to ABA OBD2. where on the 60-2 wheel should the sensor point when CYL1 is at TDC?

 

[JettaG60MK2Rider]

so there is no way to achieve this on a 9a with ABA serp setup? :beer:

034 tone wheel. with ABA space kit. 3 hours on bridgeport. custom spacing on sensor, and wheel set to 14th tooth after the 2 tooth gap at TDC. this is confirmed:thumbup:
put this one to bed

[REPOMAN]

I will be working on my Corrado tomarrow, I will count but i believe mine is 14 teeth before .
I will confirm it tomarrow.
I do know this is the same setting as when i used the internal OEM trigger wheel.
:beer::beer:

 

[REPOMAN]

My sensor is mounted to trigger 14 teeth after the space on the wheel at TDC. So the pick up sees the missing teeth and fires at the 14th tooth it reads after the missing ones. this is programmed into my EFI. All Aftermarket EFI are programmable to any number you want.
I used this setting on the OEM crank trigger wheel and the external mounted one i made.

This is at TDC. See the gap.

 

[JettaG60MK2Rider]

yes sir! and i kindly thank you for posting a pic

 

[audib6neusp30]

Bringing this thread back from the dead, can this still e made and purchased?

 

[JettaG60MK2Rider]

034 motor sports sells the wheel. i will say i had to do some fab work to get it to work with my ABF setup on a 9A.. but one of the dudes who posted above makes them as well
god be with you:laugh:
