this is a good tool and easy to use i made my own and it worked awesome.

I have a question. The stud screws down in the rocker arm bolt hole and bottoms out then the nut us applied to apply the pressure. Any concern with the stud doing damage to the head at the bottom of the bolt hole? Looks like a great tool! Thanks Larry!

I don't know how thick the head is beyond the hole but you don't have to torque the stud in but hand tight. I couldn't imagine torquing the stud so tight it breaks through the head. I did mine and no damage at all.

If you mean pulling the threads out when wrenching the nut then no to that too. The loads at max rpm full valve lift is greater than required to compress the sping just far enough to remove the keepers.

When you start cranking on the nut the stud will also tighten in the hole. I guess my question is will the stud stop trying to tighten itself when the bottom is reached or will it dig down as you tighten the nut down on it. Thanks.

I fabbed one of these up in the garage tonight, and tested it out on a motor sitting on the stand. I'll say this, if you'll ever change valve springs on an LS1, PICK ONE UP !!! Larry's price of $25 is more than worth it, trust me. I wish I had an inch/lb torque wrench to measure the torque needed, because when testing with my regular torque wrench I put it at the minimum 15lb/ft. and it never clicked. I used a regular rocker bolt on mine (can you say ghetto?) and that worked fine. Larry's setup is even better, with the stud.

Like Brian has said in the previous reply, it takes very little torque on the nut to turn it. A little lub on the bracket/nut/threads will make it turn even easier.

The stud will not "dig down as you tighten". At least it did not for me.

That is what I needed! Thanks Larry and Brian! I may try to fab one up, but will probably just pick up one of Larrys. Being the tight wade I am though I gotta try first!

How long would it take you to get one of these to me? I need one ASAP so i can get my car going again, this would save me $150 in labor at a shop.
Maybe you can rush one out to me?

thanks

I have the one I used on my engine that I could send you. The stud is 1/4" shorter than the one I will be supplying with the new batch but it worked with my 26918 springs.

The new batch should be ready to ship next week.

Has anyone tried with with double springs, such as REV or the new Crane springs?

Dave Carney

I will on Tuesday, i made mine at home, same design

humanoid i have used one i made on the dual rev springs this last weekend 9/6. i had a broke spring and i used the tool and it worked fine. the difference in the one i made is that i used a longer metric bolt that i got from home depot instead of a stud. once you get in a groove it does not take long at all to change all the springs especialy with air tools.

Using a bolt can be a dangerous situation. If you start applying load before you have enough thread engagement the threads could strip in the head. I haven't seen many bolts with enough threads to have enough thread to engage and then travel far enough to install the keepers. Particularly when installing a tall free length spring. Remember you are screwing into aluminum.

It will work with a longer bolt, I did it. I made one of these tools for my cam/spring swap and bought a bolt about 3 inches long, and also bought a nut/washer for it. You just turn the nut all the way to the top of the bolt head with the washer under the nut, then tighten the bolt in the rocker hole, and tighten the nut down to compress the spring. That way if you're worried about turning the bolt while you turn the nut, you can just use a ratchet/wrench to hold the bolt head while you turn the nut. It's a little more work, but I couldn't find any studs in the amount of time I had. Tool worked great, finished all 16 springs in about 4 1/2 hours.

Tools are ready to go out. First batch will ship today. I'm supplying a 5/32" socket head stud. This will make things go a lot faster.

Let me know if any of you have any problems or need help.

I just bought a T1 cam and will be needing an install tool and this sounds like an ideal tool for my garage. I will send you an email Larry.

Of the 23 people that agreed to buy the tool when they were manufactured, I have only heard from 13 so far.

Would like to hear from the 10 of you that committed to buying the tool and have not contacted me. Please let me know if you still want it?

Dave Carney

I made one of these and used it on a full set of crane doubles. Works GREAT! Couldn't be any easier. I made my stud out of 8mm threaded rod (pretty soft stuff) and the stud made it through all 16 springs although I'll need to cut a new one for next time. Whatever Larry is supplying is probably much better.

This thing looks great, top quality in person. Thanks Larry for setting this up, it will be a permanent addition to my LS1 toolbox. I'm sure I'll use it many times
