NOS 3 and 1/8 Wheel Puller

[Chuck Kuntz]

NOS wheel puller that is 3 and 1/8 inches across the top of the threads when adjusted as shown. 16 threads per inch. I am not sure how to determine the diameter when they are adjustable. $35

For anyone not familiar with these, that side bolt isn't actually an "adjustment" per se. Although it is in a sense an "adjustment". Clear as mud?

 

It is necessary for the threaded fit onto the hub to be loose enough to twist on as needed. Not being locked really really tight onto the hub threads, if a wheel resists being pulled, and a bit much force is put onto the bolt against the axle end? Sometimes the slight looseness in the threads will allow the threads on either the hub or the puller to strip off, usually damaging both the hub and the puller.

The hub pullers with the side slit and the "tightening bolt" greatly reduce that risk if properly used. Before putting the hub puller onto the hub, back out the knocker bolt (hits against the end of the axle), back off the tightening bolt, and check for fit onto the hub's threads. If the fit is good? Spin the hub puller as far onto the hub's threads as it is willing to go. Then tighten the side bolt across the slit. Don't go crazy with it, high torque is not needed, but about a box end wrench amount of tight. That clamps the threads as deep as they want to go, and seizes the hub as tight as the puller is capable of. Then twist the end bolt down tightly against the axle end inside.  Wrench it fairly hard! Then if needed, tap the head of that end bolt with a medium hammer. If needed, tighten, tap, tighten, tap, and tighten again. Hopefully by this time the wheel is sitting in your lap.

It is still possible to strip the threads with this type of puller. Personally, I have really gotten onto a few pretty hard! I haven't stripped one of this type yet.

 

Measuring the size? Should be done with the side bolt loosened. IF the puller hasn't been distorted by over tightening, the thread size should be measured like the non-clamping type pullers. I have seen ones that someone tried to force onto a smaller size. But all they managed to do was ruin a good puller. They will not pull down far enough to fit a smaller hub.

In the photos? This one looks like a very nice puller. If it is the size you need.

Would you-or anyone-have a 3 3/8" wheel puller with the "side clamp" bolt like the one you have pictured? Thanks.

Not that I know of.
