who sells these?

That is a great price for this tool. If I didn’t already own one, I would jump on it.

believe it or not, I bent the big screw that is part of my flywheel puller. some of these damn flywheels are so tight I guess it was bound to happen eventually. I have probably used it 50 or 60 times, but I thought it should last a lifetime.

anybody know where I can buy a new one? doesn’t look like something you can just pick up at any hardware store.

No, you can’t get it at the hardware store; its an Acme thread, not a normal 60 degree thread. Acme threads are used where especially heavy load bearing work is to be done.

McMaster Carr carries threaded rod in various Acme thread configurations. You’ll need to know the diameter and thread pitch in order to get the right one. Measure the outside diameter for the size, and for thread pitch count the number of threads in one inch of length.

Hope this helps.

Is that Acme thread? Hard to be sure from the pic but it looks like 60 deg V thread to me.

maybe the angle or lighting, or my bad eyes, but the threads look square to me….. only the beholder knows for sure…..

I’ve had my OMC puller since the 1950’s. Expensive, but it works where the other stuff just gives you a fit. And you can’t kill it. Well, I guess I’ve killed a couple of the 1/4" bolts.

Get yourself one of these. 😉

Wedgie is that an OMC puller? What is one of those going to cost me?

The real question is, what is it going to cost you in aggravated moments, if you DON’T buy one.

Long live American manufacturing!

You are correct , the threads are indeed square. I will check out McMaster-carr’s site. How would I attach a nut onto it though? Weld one on I guess. And machine the point to match my bent one. What a bunch of bs.
Thanks for the help guys.

[pm-t2]

Order a nut (or two) to go with the threaded rod. They sell the rod, they might have nuts too.

Or alternative – grind off some threads, weld a conventional nut to the wrench end, or put a nut on that fits over the Acme threads and weld that….

I have always used a steering wheel puller. Has the fine threads, grease the bolt, three 1/4×20 4" bolts with large washers, has the swivel point on the big bolt, and there you go. I even have always used grade 5 bolts and have never broken one.

But of course I was never a professional mechanic, so I guess I didn’t know any better 🙂

Looks like a simple fix to me. Use a tap and drill chart to determine drill size suitable for tap
to next size larger FINE thread. Dril, tap to new thread. Threaded rod in fine thread is usually
hardened, cut off a suitable length and grind a point on one end and weld or double nut the
other end.
OR use press and straight edge to straighten the bolt using nut to support the ends rotate
bolt to high side and press, check and continue until straight. It may help to use a third
nut in bend area to limit depth of pressing. I have done this on a bent clamp screw so
it should work on forcing screw.
Long shot you may be able to buy OEM replacement screw.
Lathe happy types might just turn a larger screw down and fully thread.
Common bolts are not threaded full length.
A fastener outlet or mill supply store MIGHT have and be willing to sell a single
replacement full length threaded screw.

At one time I had a "bright" idea of duplicating OMC tool with a replaceable nut in place
of threading. I had a machinist make up four samples. He quoted me a cost
of $35 each to make them in lots of 100. End of not so bright idea.
I still have and use one of them.
Gave another to a small engine repair shop to try out…too small diameter for some of the
engines he worked on.
