installing the 3500 crank trigger wheel

[SappySE107]

So I pulled it off without marking it, figuring it was keyed somehow. If it is, I don't know what im looking for Anyone know how to set it up or if I should just figure it getting balanced without it and using the external trigger.

You're a little short on detail but I gather you are talking about a 7x ring to replace the one that came with the crank originally.

I put a balancer lightly on a 7x crank, then glued a long piece of thread with a little weight attached to it to the face of the balancer after lining the thread up so that it passed through the center of the number #1 crank notch.

I then installed the balancer on the 3500 crank and marked the point beneath the thread on the crank and lined the #1 notch on the 7x ring up with the mark I put on the crank.

The crank was standing on its flange end of course and though I can't believe it, I didn't take pictures to illustrate it. Just be mindful that the ring is not installed backwards.

i dont have anything to replace the stock 900x sensor wheel so that is what I want to put on. I have no idea what goes where.

Joseph, didnt you have a guy that made a press on ring for the 3500crank to use the earlier 3400 computer?

[CNCguy]

Ben... could you please measure the outside diameter of the hub where the ring presses on? I am curious about how the diameter compares to a 3400 hub and if it would be possible to put slots in the 3500 hub.

[bszopi]

The 3500 hub outside diameter is the same as the 3400 diameter, except without the notches. So yes, it would be possible to just notch the 3500 hub.

Thanks Brad

I installed my 3100 crank pulley on my 3500, had no idea things needed to be marked though

I did do a CASE learn with my tuner though... so it shouldn't matter?

[gectek]

pulley doesnt matter, it is the fact that the timing ring has to be indexed to the crank. pulley is used as a reference because it is keyed and wont move in relation to its position on the crank from one to the other

[PCGUY112887]

Is this not the timing ring that is attached to the pulley?

[gectek]

nope...on the crank

[gar70614]

i belive there talking about the ring that is pressed onto the crank itself.

[bszopi]

Yes, we are talking about the 7x wheel, not the 24x wheel.

I hate to be the forum idiot but,
my 2000" 3100 crank pulley/dampner along with crank trigger fit right on my
05" 3500
just in trial stages currently,
what does the crank trigger kit,offered in the store for this conversion do?
what don't i know?
wait! don't answer that,lol
what is it that the trigger kit does that is different from simply changing around what i have?

[SappySE107]

That is a 24x crank trigger for SFI. The TCE external trigger is for the 7x sensor, which is for spark and fuel.
