I used the washer off the old bolt too.
FYI - The only kit that I could find locally that would work was at Northern Tool (W89710).

Strikeking Ok to drive for a couple more days or disaster waiting to happen? I did mark the hub in the pully and the marks are staying aligned so I don't think it is slipping. Yet!

Strikeking Missing some rubber from the back of my HB. Took some snake cam video but won't let me upload it. Has a tiny bit of wobble I feel causing the belt to make noise. No noticeable vibrations with the Hemi. The front of the harmonic balancer looks okay. ( I think)

PolkaPower Crown makes decent stuff. I've used their water pumps before.

Raffish Thanks.
I just cancelled my (possibly?) incorrect part coming from RA and PM'ed Kolak for the crown replacement...
03-20-2017 03:35 PM
PolkaPower It's kind of a time bomb. It may last months or it could give out today. There's no way to tell unless you drive it until it fails.
Kolak has all the part numbers. He sells a lot of Mopar stuff too.
03-20-2017 03:11 PM
Raffish Haha Kolak is the one trying to sell me $30 crown balancer now!
And RA is telling me part number 5037394AA will work while Mopar site lists that for the 6.1L. ( Mopar site has part # 4792815AA listed for me)
What to do?
Also I'd say the center of the balancer is wobbling about 1/4". Is this somethign that will immenently explode on me or can I keep driving until new part arrives..??
Thanks

Raffish Ordered Mopar.
RockAuto lists part number 5037394AA for my 2005 JGC 5.7L
Mopar website has that for '07-'10 SRT8 and 4792815AA for me..

What gives??

Not positive, but I think I've read or heard that it is a slight underdrive compared to the stock 5.7 pulley. It would be interesting to know and, if it is, how much of an underdrive. The ones on both of mine are SLP 25% UD.

PolkaPower I've noticed that my hb pulley has a little bit of budget in the rubber so I'm probably looking at replacing it sooner than later.

I agree, don't cheap out on this one. You'll be at the stealer anyway to pick up a new bolt. Another option is to go with an underdrive pulley like I did on both my Hemi's. No "actual" horsepower gain, but the accessories are driven easier due to the smaller diameter pulley which can seem like a little more hp. I've had mine on both for several years now and haven't had any problems (like some said I would) with low battery charge or lack of power steering, etc. As an example, my last battery in the Jeep lasted 7 years, about the last 3 with the UD pulley installed.
