ATI Balancer pinning kit warning Hey gang.
So I bought the ATI pinning kit and installed the pin. I used the 918993 tool.
Front cover is off for a cam swap. Decided now is the time to remove the oil pump drive and crank gear and guess what?
With the new pin in place (the location is wherever you put it) there isn't enough room for the oil pump drive to disengage it's keyway bofore hitting the new pin I just installed. Wonderful!
It turns out that there is a 918993-1 kit that requires the pump drive and crank gear to be removed and is keyed so the new pin aligns perfectly with the existing key.
Interesting huh? Because if you were to pin the crank with the timing cover installed (the way the kit works) and then at some later date you wanted to replace the crank gear, you are stuck just like I am now.
It's not a huge deal because I can punch the pin out but wouldn't it have been nice if this were known ahead of time? I would have bought the other kit.
So just a heads up for tohose who would like to pin the crank this way in the future.
Still baffles the shyt out of me why GM didn't just have a keyed balancer.
