Can't remove dampner

Went to change ot a timing cover seal do to a leak and am having trouble gettig the ballancer off. I borrowed a snap on removal tool from a friend and tried to remove but no luck. It even broke one of the cap's you put on the end of the tool. It is an ATI dampner on a Callies crank and has only been on one summer (7000 mi ) any help would be much appreciated. Mike

Re: Can't remove dampner

1. Make sure each bolt/washer is touching the puller web at the same place. Even if one bolt is off 1/2 thread, throws the pull in a bind.
2. Add a coffee can or shield around the installed puller in case of breakage - cetainly wouldn't need to make an emergency visit.
3. Give the puller a hard pull and rap the screw hard.

Re: Can't remove dampner

Mike,
Did you assemble the engine ? How hard was the damper to install ? ATI leaves thier dampers on the tight side and probably 50% of them need to be honed to the proper fit, especially with aftermarket crankshafts. If it was too tight and installed anyway, it can be a beeetch to get back off Try using an impact wrench, a lot of times that will work a lot better that a breaker bar.

Also, and this is going to sound stupid but .... if it is a big block, make sure you removed the washer that goes under the crank bolt.

Re: Can't remove dampner

Thanks to all. I got it off and didn't ruin it. I ended up putting a bar between some flywheel bolts on the end of the crank and put away the impact and used a breaker bar on the puller and got it off. Thanks again Mike

Mike,
Before you put it back on, get a good micrometer and measure the crank snout. Then take the micrometer and the damper to your machine shop and have them hone it for the proper press fit. If its a small block I think it is around .0007" I have the numbers at the shop in my ATI catalog.
