Harmonic balancer help and info needed

[snowwolf]

Noticed when I lifted the hood the serp belt had run over half off the tensioner pulley, had a spare new tensioner and fitted, on start up I noticed the harmonic balancer / crank pulley had the dreaded wobble. Probably about 2mm run out on tick over, I need to replace the HB would you suggest a standard pulley again of perhaps an ATI or other brand?
I live in the UK so these items are very hard to get and looks like my local dealer can get an ATI In about 2 months at a cost of £510 = $760 and a standard one in 4 weeks at £200 = $300

Is the best procedure getting the bolt undone is using a very robust electric nut gun or air gun and I take it using these should eliminate having to lock the fly wheel ?

Any other suggestions removal and help in getting one sooner I would appreciate it

Regards Mick

Mick, the tool to lock the flywheel is expensive but worth it in the end. You will need a very good impact to loosen the HB bolt.
You can talk to Crazy Paul, he may be able to get items delivered to you at a lower cost then shipping through the US.
The ATI is the most expensive one. Power Bond or SLP offer an underdrive pulley.

Cheers Ray, I have ordered a new GM pulley from Monkfish performance over here in the UK, very good company to deal with, I would let them fit the new pulley but adds £100 in fuel costs to drive toy their workshop, so going to give it a go myself.

I was talking about the Kent-Moore tool. That hand fabricated tool should be fine. He isn't a vendor here so I would never post a link to his forum page for sale add.

Sorry, didn't know member made tools followed vendor rules. I'll edit my link. I know better as I'm on a million forums and run one myself, hard to keep up with all the different rules. My bad.

I was just giving an option, I found it randomly through Google and snagged one.

It's an option. I didn't intend to be snippy if you were thinking that. I was lucky enough to borrow the Kent Moore.

EDIT:

It was never my intention to prevent any links to a fabricated tool. This is a tool, not a vendors specific item. You can place your link back in your post..
