1010 track master pin removal tool

[stmftr395]

If the pictures have downloaded you wil be able to see the tool I tried to discribe. The view on the floor shows the bending caused by use. To use this again I will add a gusset to the pipe end after straightening. I had to remove the cylinder safety guide as it was welded on after inserting and extending the cylinders piston. The next guide will be made of pipe large enough to allow the insertion and removal of the cylinder. I used what material I had lying around to make this unit, but if I were to buy steel specifically for this project I would use 3" channel, Two pieces back to back with 3/4" pipe nipples in between. Makes a very rigid strong back. I will answer any further questions just e mail me.

Lets try again.

Will the third time be the charm?

Just doesn't seem like it would be heavy enough to get the job done. Here's a couple of pictures of two different portable presses made by WTC in Waukesha, WI. Maybe it'll spark a few other ideas. The top one is a 100 ton unit and the bottom is a 150 ton.

I looked at those units before I started making mine. I don't have a 100 ton portapower so I fabricated it with a 10 tonner in mind. Even though it did turn out a little light, I used it successfully in removing the pins from my tracks. Before using again or were making another I would beef it up as I discribed earlier. Mark.

do you mean the master pin, or the link pins?

A master pin press might not work if you have the original style headed master pin. I would guess that it will not go through the pin receiver on the press. Master pin presses are designed for drive master pins typically found on larger crawlers, however you will see them on the small crawlers as well. I use a large air hammer on master pins, had the best luck with that. Otherwise, a big hammer and punch, but that is kind of a pain at times.
WTC used to make a master pin remover like stmftr is making, but it just had a clamp to hold it to the pad, and a long shaft that you hit with a hammer.

They still do Lavoy. I tried to get a quote out of them a year or so back and couldn't even get a phone or email reply. Must be great having so much business that you can just blow people off. I've always thought this thing would be easy to make if somebody was so inclined.

Bill; Thanks for the picture of the pin removal tool for use with a hammer. Moe ideas for the future! Mark

[Lavoy]

Bill,
Trust me, you don't want to hear from them even if the jerks would call you back. I think they quoted me $1400 7 or 8 years ago, told them I would have to pass. Not that I begrudge anyone a profit, but there has to be at least $50 worth of material in that thing, okay, maybe $30, but I was giving them the benefit of the doubt.
As to somebody being inclined, sounds like a project for Bill.

That is an awesome idea for a pin punch, maybe I will make one. The thing I would do different is put tension springs between clamp and striking pad to keep the thing on the pin and not fly into orbit after bouncing off from a good whack. Probably should try to come up with some tool steel for the pad and rod.

If you go to WTC and read the descrition under all of the items pictured above, all of them are "master pin" removal tools. I'm pretty sure these are not for the other pins in the chains.
