aaaaaaand that's why I bought a pulley tool.

I had the longer bolt with washers that wasnt the problem

I bent 2 valves during my H/C install and had to pull the head back off and take it to a machine shop. Sucks going backwards but one thing is for sure, you'll never make that mistake again.

Buy the tool & do it right this time.

I did it with the right tool. It's the exact same thing as the tool... I just didn't pull it on with the long bolt as far as I should have. I was in a hurry and that's just what happens when you don't take your time with an important part. Instead of having it done in 3 day it's going to take me a week. If I ever do it again I will use the longer bolt or install tool and pull it on plenty, I will heat the pulley, and I will make sure it's not going on to hard

Most peeps can't purchase from Grainger. I found it at Slamazon way less:

Do you guys think I should take the pulley off to do the helicoil? I kinda think it will help me keep the drill straight whil drilling for the new threads?

yea, but look above I already bought the oreily one. I hope it works as well

When using the install tool, I add a wheel bearing (if the tool doesn't already use one), & grease up the washers & bolt head to reduce friction.

A drill bit will always want to wander into the softer material. In this case, it should stay centered in the hole all by itself. Of course, you'll want to keep it as centered as possible. Use a slow drill speed and lots of lube. Back out often to keep the chips clear.

DON'T RUSH IT.

If you think the longer bolt is the same as the right tool it proves you really don't understand what it is you did wrong. That means you are likely to repeat the mistake. With the correct tool the tool threads take the stress of the twisting-turning force, not the crank threads.

No. Just no. Sell your tools and buy crayons, your car will .

I agree, The tool uses the threads in the crank as a foundation to hold it in place. There is NO twisting forces exerted against the crank threads during install.

You hand thread the tool into the crank, hold it in place with a wrench while sliding a threaded bearing down the rod to push the damper on.

There is zero risk of stripping the threads in the crank and the pulley slips right on. Took me 5 minutes with the HAWK tool and was not hard at all.


OP, I will sell you mine if you need one.

Everyone on here will tell you NOT to use a bolt to install especially now.

I used a longer ls7 bolt to install it, zero problems. Just thread it in far enough to be effective. Sounds like the other one is probably safer, but id bet 99 percent of the time the longer bolt will work fine.

Cool story

I know people have been sucessful doing it this way, but MANY..MANY more have stripped or boogered up threads with this method.

If you do a search, there are countless threads on why you shouldnt do it this way.

I would like to respectfully say, you shouldnt pass this on as an effective means to install a damper.

There is a correct way to do this with the proper tool.

I don't know if I should fix the threads and try and put it on or wait tell I can get an install tool. I might try to fix them and than heat it up and slide it on and if it doesn't slide on by itself I'll just buy the install tool

RENT the install tool, and return it when you are done....
costs you a deposit, that you get back when you return the tool...
cost = Free99
