4.7 v8 camshaft sproket removal

So I'm replacing the timing chain guides on my 2000 jeep wj 4.7 v8. So I'm just putting a entire new kit in. Anyway, I can not seem to find the tool to hold the camshaft sproket in place while you remove the bolt holding on the sproket. I'd rather not go with the vice grip method (not comfortable doing that really). Have any of you guys ever used the holding tool I am talking about? I've seen a few videos that have used it but they dont post any links. Thank you all in advance!!

I was also hesitant about the vise grip method, but eventually tried it. I actually used 2 vice grips to help get additional grip without having to REALLY tightening them down, and put shop towels between the jaws and the crank shaft to not mar it up. Hit it with the air impact and it popped right off.

You don't necessarily need a vise grip anyway. A common pipe wrench works. I'm not saying so officially though so do anything at your own risk!

Thank you for the advice! I'll certainly go the two vice grips and a cloth inbetween. Hmm pipe wrench you say... adventurous.

A pipe wrench is more specifically designed to do exactly what you need it to do with greater surface contact than a vise grip. If anything it should work better.

I actually tried both. The pipe wrench held better by far than the vise grip did with less slipping and thus less marring. Either one should beat using your teeth.

the vice grip method is a little scary sounding but it's totally fine. I've done it several times. I have 260,000k miles on my engine. Original owner.

Did you put a piece of cloth between the jaws of the vice grips, or a old belt I've heard both ways. Thank you!

No. You loose bite.

Breaking the bolt free and re-torquing will take all the bite you can get

Two arms - a large pipe wrench in one hand pulling the camshaft in one direction and a 1/2" torque wrench (or breaker bar, for removal) pushing the bolt in the other direction. Easy-peasy. This, after trying various other ways of doing it.
