Crank Pulley Wobble

[bigbflex]

I just bought a 97 Yukon the other day, and today I noticed the crank pulley has a little wobble to it. Is there a write up on how to change it?
Thanks

Need to be torqued or loctite?

 

[SunlitComet]

the torque I could not find but loctite is always good. I would not go more then 40ftlbs on torque though IMO.

Could not find torque but loctite could not hurt. IU would not put more the 30-40 pounds on the pulley bolts though. the damper to crank is already at 70ftlbs.

Is there a way to tell if it's the balancer rather than the pulley?

Yeah look at he balancer ... you should be able to tell by looking at it which is wobbling.

 

[SunlitComet]

retorq is correct they are 2 different assys.

Got in there with a flashlight...the balancer is wobbling as well. Are they hard to change?

How do I keep the pulley from turning?

Pull the flywheel cover and use a flywheel tool to hold the crank from turning.
