Some new 60V6 products

[CNCguy]

I have finally given in and am making a batch of internal trigger wheels for the LX engines. My attitude was that there wouldn't be that much demand for them due to all the work and expense of installing them but after being asked repeatedly, I am moving forward with them. Using one requires removal of the crank, pressing the old rings off, properly pressing the new ring on and reinstalling the crank. Of course, a spacer must be used to move the 7X CPS to the correct position. The kits will come with the trigger ring and CPS spacer. They should be ready for sale in a couple of weeks. Price has not been established yet.

First piece off the machine - Dimple between slots marks which side goes towards front of engine.

Awesome! Now I just need to decide if I want to go this route or not... LOL! Do you have a way to locate where the dimple needs to be placed on the crank to ensure proper triggering?

Index bob weight, secure string location at balancer, transfer and mark the location on the new crank.

I've been meaning to have some more made but the shop could not assure the plans they found were for the final piece and I've been so busy with the car during my visits home I haven't taken anytime to do follow up measurements to order another batch, that along with wanting to provide a complete package with spacer as CNCguy is planning just kept the idea on the back burner.

Alignment is pretty important. I am considering making some loaner tools that will slide on in place of the dampener with a small hole to put a string and weight. Users would just pay a deposit and shipping charges. The cheapest and simplest is like Joseph said but you need an old crank to reference from. I wish there were an easier, more accurate way to install the rings. I had also considered putting a line on the ring that could be lined up with a reference point on the crank but most everything that could be used is not machined. Of course, being off .100 is just under 2 degrees which would probably be ok if you are tuning the engine.


Joseph: I assumed that you didn't want the hassle of having parts made and holding them until they sold.

No problem at all, I was more concerned about the occasional need going unaddressed by those interested in doing the swap without the external 7x unit offered in the store. They (rings) didn't stick around long and I was more interested in seeing the new engines at work so I didn't give much consideration to what a fair markup cost should be for my efforts. I was glad to make a contribution. I have some other ideas I plan to put more effort into though, like a more practical approach to a solid flywheel for the 6 speed swap.

I have been telling a friend that he should look into that same product for vehicles that came equipped with the 6 speed. Getting rid of mass that rotates at engine speed has the same effect as adding horsepower. It would be a nice upgrade for a G6 with no emission concerns.

Will the internal trigger wheels for the LX engines fit the 3900 also?

[CNCguy]

I honestly don't know. Perhaps Joseph may know the answer to this.

The 3500 non VVT and 3900 have the same crank (except for the ring) as I have both engines and each has one of the rings I had made in place.

this is something i'm really going to consider if my plans don't work out with the external one.


FYI, on the stock 3500 58x trigger the 7x marks are there as dimples in the side. a machine shop could transfer those to the crank then line up the new wheel pretty easy. no need for special tools.

see, now that's cool. GM was obviously thinking of us when they did this.

That's great, except I already removed the stock rings...

see, now i have reason to procrastinate.

I'm just sitting here saying DUH. That's a hell of an idea Dave.... that's why you get paid the bug bucks. Now I need to find the correlation between the two rings and mark the new rings. Thanks Dave.

how about a plate that bolts to the dampener with a edge that sticks out for a string and weight. should be cheap enough to make a plate shaped like a Q...? this is a great idea though Mark.

EDIT: oops. old thread. So what happened with this all?
