Default Autozone Pulley Puller

I put this in internal since it is usually to do with a cam swap!

Need to pull the balancer for H/C swap this weekend, are the autozone pullers any good, and which should I use? They have one for "threaded pullies" then two of they typical 3-arm generic ones.

Any input?

Thanks
-Dave

the threaded one won't work on a stock pulley. I used a 6" 3-arm puller from oreilly's and it was very difficult to use on the stock pulley and would not fit behind the crank gear so I could change the timing chain. I probably could have flattened down the ends of the arms with a grinder and it would have worked... but I ended up borrowing a nice set of Snap-On pullers from a mechanic friend of mine.

I have done 2 cam swaps and 1 pulley swap with the auto zone puller.. Just use your old crank bolt.... It comes almost all the way out then you just have to wiggle the pulley off the last bit.

I'm planning to use the old bolt both to remove the pulley (essentially extend the puller's bolt) and put the pulley back on....

Sound good?

Thanks guys

If you are planning on putting the stock pulley back on you should plan now and go take a crank pulley bolt to a bolt shop and tell them you need one half an inch longer. It'll cost $1 or so and it'll give you enough length to get the pulley started onto the crank snout.

Autozone has the following:

3 jaw 7" spread
2 jaw 6" spread
3 jaw unmarked, looks like 4 or 5" spread, definitely smaller jaws than either of the others.....

Buy the bolt...it'll be safer anyways because even if you do get the pulley barely started by hammering it on, those first 2 threads in the crank snout are gonna be REALLY stressed when thats all you are pulling on. The longer bolt will allow it to grab more threads.

It costs one dollar dude...take your new crankbolt you should already have from GM and tell a place to match it but make it a little longer. Took the place I went to maybe 30 seconds to find a bolt and washer.

Some vendors should sell these longer bolts. Hell, I bet if somebody stuck a GM logo on the bolt head and made up some part number like 12544393 they could sell them for $20 each as an official tool! <img border="0" title="" alt="[Big Grin]" src="gr_grin.gif" />

My bolt has been passed around for at least 10 pulley installs in austin so far....best $1 I ever spent. Next time I'm near the bolt shop maybe I'll pick up a few and can mail them to people that need em.

Do NOT use a hammer... Get the threaded rod.
