Slipped dampener

Stab it and steer it
Well I've got the water pump off for replacement so I figure I'm gonna do some serious checking on timing marks. (Just about impossible with everything together.) Anyway, I figure I'm 2.3* off.

Can I change the dampener AND the seal without pulling the front cover? Or do I just remark the dampener. If so which dampener do I get. Engine is stock.

The photo shows the dampener. The marks are as follows center mark is, of course, the the factory TDC mark. The other two are my marks coming up against the piston stop on each side the difference is obvious.

Re: Slipped dampener

well you could probably remark it but no guarantee it won't slip again. i think it's the 6.25 205/250 balancer

Re: Slipped dampener

The more I think about it the more I think I'm gonna leave well enough alone. It's easy to add degrees now that I know for sure. At least I have "proof" The best proof would be to pull the dampener, commonly the keyway and TDC are aligned. Not sure on our motors.

I've got other things to do anyway. Big tranny cooler being the main thing.

Thanks guys,

Re: Slipped dampener

you can change the damper easily without doing damage to anything else. seal can also be changed at the same time. I wouldnt trust that damper. it's already slipped and whos to say it wont seperate the next time you drive it. another reason I have stock dampers.

Re: Slipped dampener

Don if you decide to reinstall another. Take a measurement of how far it sits away from the block. I have had a few problems installing them far enough in. You could borrow the tools you need from Advanced auto parts & do not use a hammer.

Yeah....no....don't use a hammer. It's far too simple to do with the right tools. In fact, most pullers have the installer in the box. Rent one from a local parts store, lube the threads really well (in the crank snout and on the tool) and go slowly. Refrain from using an impact gun until the balancer is already moving smoothly off. Once off, inspect the crank snout for bad spots and clean it up with some fine emery cloth if need be. Put a little grease on the seal lip before reinstalling the new balancer and start installing. Again, go slowly and make sure the tool and threads stay cool and lubricated.

Pretty simple job.

If you'd ever consider the DIS system that Dig, Renz, & myself are working on, then you may wanna go with the balancer for that (Pioneer 872001). Otherwise, I'd get a Fluidampr or good Pioneer one.

Re: Slipped dampener

Don, look at the Pioneer damper. All steel, no rubber, NHRA approved IIRC, and not spendy. It's a damned good unit have 5 of them but I'll be damned if I can think of the part #?? I post back later.

Re: Slipped dampener

Just curious? I thought that after you use the piston stop on both cycles of the motor to find TDC for #1 then you cut those in half and that is where your #1 TDC lines is supposed to be? If so your picture shows a perfect mark as your dampener hasn't slipped? Please inform me if im wrong, the reason i am asking is i am about to use a piston stop on my new motor and i dont want to mess it up. Thanks, Paul Z.

Re: Slipped dampener

Well to me the marks show a difference between the TDC mark on the damper and the 2 marks I made with the piston stop. However once I removed the damper and checked it against the new one it wasn't slipped. I've come to believe that using a spark plug hole type piston stop is unreliable. I can't help but think that a "true" piston stop (the kind that works without the head installed) and a degree wheel is the most accurate method.:2cents:

Re: Slipped dampener

so you take the two points made by the piston stop and cut them in half and there is your good #1 TDC timing mark? I think thats how i understand it??? But then again i am polish.hahaha
