He's already shown that the cam timing issue is relative to the keyway, not just the TDC mark. Also, in the ATI product photo I posted above, you can actually see that the keyway isn't lined up with a cog 'valley' like on the OEM gear.

The amount of high $ aftermarket shit that shows up on this forum that has glaring issues is staggering. There are tons of people running stupid power on OE crank balancers, it gets you thinking. |

What about repairing it? That rear plate is removable and installs with a small swage pin. I could drill the hole for the pin in removable plate.
BUT - I'm at work and not looking directly at it, is the woodruff key - to the - gear teeth a permanent thing? If the two pieces can't be separated, you would need to rotate the damper roughly 172deg, re-broach the keyway, and add your own scribe marks for TDC.

Sorry, I was a little slow on the pickup there- edited post accordingly. I still wonder about the position of the timing wheel relative to the keyway.

Yeah no kidding, but it's even worse specifically with this product: over the years they've made a LOT of mistakes specifically with the ati damper, not just this.

This. At times it drives me pretty close to jumping ship.

So do we have any dampers that we know are good to go now? I know BHJ and now ATI have issues

I have been eyeing the JPM Damper. Its definitely not cheap. JPM Crankshaft Damper
BHJ's Mazda 1.8 race damper is the preferred Harmonic Damper at Jesse Prather Motorsports. Shown here in Eric Prill's F Production Miata. Click here for Jesse Prather Motorsports. |
I have Jesse Prather's balancer, but the car has not run with it yet. I checked the timing belt clocking, and it is like factory. Here are a few things I have noticed however:
First, there is little to no coating on the steal surfaces, and it started to rust quickly. I will have to sand the rust off and paint it, which pisses me off after spending over $800. Second, it was borderline to small to fit over the crankshaft. Hoping it wont be an issue when i pull it off. Next time I install I will try heating it in an oven. One of the ignition wheel fasteners was bad and had to be replaced. Not that big a deal, but for the money I spent, damn! The trigger wheel clocking is different from the original Electromotive trigger wheel kit I got years ago. Not sure whats going on there unless there has been a change in where Electromotive mounts the trigger. That or one of them is F'ed up. BHJ balancer and trigger wheel is set up for Electromotive management that Jesse Prather helped develop. |

So I just checked mine, here's a picture seems like it's lined up correctly. For reference I bought it in May/june 2017. |
|
^ how does the key lineup with the timing belt teeth? That seems to be the issue.
|
Ah, crap. Hopefully, I have a picture of mine so I can verify if its right or not...

Mines coming off in a few weeks to replace Boundary Engineering's leaking front main seal

I just used a cheap AutoZone one. Worked fine.
