Has anyone had a problem with the ATI Damper setting too far back and making the timing belt rub the backing plate on the head?
I have installed the original balancer and the timing belt is fine.

 

Is there a belt guide attached to the back of it ? There are two sizes available depending on weather or not you're running a timing wheel. FM has both under engine internal parts. Fredb

 

im running 36-2 trigger wheel and the guide for a trigger wheel

 

Is it the right guide ? The thick one if used with the timing wheel would push the belt back. Fredb

 

There are two different guides, you have to use the right one

 

the guide I have has the correct part number stamped on it.

 

Ok , let's try this from a different angle. Are the cam pullies properly seated and tight ? Fredb

 

Fredb I have torqued every bolt on this engine
This is a full engine build
Saturday I removed the ATI damper and installed the original factory damper and reset the timing and all fits the way it should.
so I have narrowed it down.

 

Please provide a pic of the ATI Damper with installed trigger wheel, and a front view of the cam gears.

 

 

see attached photos

 

with original factory damper installed

 

looks like ATI Super Dampers are out of stock....

 

Only choice may be to run stock damper and hope engine holds together...

 

What is the thickness of the belt guide also post pictures of the guide on the damper. This seems like the only thing it could be. I find it odd that there are hundreds of these out there without an issue and this one isnt working unless it is the wrong parts being used. Have you verified it is the thin belt guide.

 

part number shows its the right part.....

 

I guess the only other number you could check is the one from the inside of belt guide to the outside of the belt gear.

 

I'm showing 0.5mm difference when the trigger wheel is not installed, meaning if the trigger wheel was 0.5 mm thinner then there would be 0.5 mm more room on the gear.. Now would that move the belt forward when damper is installed without trigger wheel and would that 0.5 mm be enough to not rub the back plate? I don't know without installing it which I hate to do because it is a pain to remove the damper, but I will do it in the next couple of days. I was just hopping I would get this revolved with the vendor.....

 

Who did you buy it from?

 

I would like to give the vendor a couple more days to resolve this issue before I throw anyone under a bus....
I do feel like I'm having to put forth the effort to see what is going on rather than being kept up to date..
