Ford tractor rust repair

[MMW]

I have a plain MM250. I bought it new in the mid 90s when they were out. Been using it ever since. It works. I run 035 bare wire, 045 dual shield and have a 30a spool gun for it. Not as nice as the older MM200 but I use it all the time. You get used to it, not perfect but I would not hesitate to buy...

So what looks like a broken bolt is actually just a circle drawn in pencil where you need to put a hole with some threads, is that correct? Can you put 5/16 threads in there and use a shoulder bolt?

I'm still not quite sure what you want to build up, an engine block or a bell housing? ...

Here is a few pics from farther away. Top of cab is about 8ft 6" high. I will discuss numbers when job is done. Only doing this side for now. The other side is still a couple years away from this one.

To the new guys, see the fair sign on the inside windshield? Their is one lower...

The tube was 2-3/8 od so probably metric. It had about a 1/8 wall. I replaced it with a 3/16 wall 2x2 tube. Here is the new tube with mount installed and also the fenderwell to door sill repaired. I kept the top of the tube where it was supposed to be and added a 3/8" shim under the mount. I also...

Starting to cut away. The corner where the fenderwell and the door sill meet was rotted also. You can see in the top right of the pic is what is left of the tube after cutting where it connects the cab to the rear axle, just above the large bolt. This was all that could be saved. The good looking tube...

Customer dropped off his tractor that is used for snow removal. Mostly with a 3 point snow blower attached. Before he bought it was used by a college for snow. The cab frame was rotted completely out one the left side as well as a section of the floor and fenderwell. The cab had sunk down in the front...

Picked up the replacement today. Welder, running gear, pedal, ground lead, water cooler, #20 torch, box of consumables and a 25' power cord with the male/female plug. Now to hook it up. I have to swap the running gear as mine is made to fit under a bench. The factory one is to high.

Picked up the machine today. Tech said it is rectifier SR1. He said he could of disassembled it and replaced a part but I also told him that on ac it seemed like it was running wide open. He checked the "lem" (I don't know what this is) and that checked out bad also. The "lem" is...

Found a dialarc HF for sale. Would I be happy with this to replace a syncrowave? I know it has a little less duty cycle and it has been mentioned on here that it is not square wave so it welds a little different. I can always get it for a temporary machine until I find another Syncro but it is even...

Got a call today from the repair center. It is terminal. Rectifier no good and unavailable. He could replace one of the three(?) but it also has an issue with it on ac it only is max amps which is another part that is unavailable also. He search a few places plus the internet and turned up nothing....

I am probably taking it into the repair place on Monday. I really don't have time or knowledge to mess with it although I will take a look this weekend to see if anything is visual just because I am curious. When I talked to the tech he asked the symptoms and then said it sounds like the rectifier....

Spoke to repair center today and tech said it sounds like the bridge rectifier. I will probably do visual on it this weekend. He said his lead time is about two weeks. Looking up the part number 114921 it is obsolete, superseded by 181106 also obsolete. Is this an expensive part if found? Can a bridge...

I no longer will fix them with fuel in them. While welding a step on one I burned through a thin spot and fuel started peeing out. We had to grab a pump quick and drain it into a drum. Then I finished welding it up. Many tanks are no longer available and almost impossible to retro fit a different...

[MMW]

What I do, steel or aluminum doesn't matter. I usually make customer drain and remove tank but I will do it if I have to. Find leak, cut patch bigger than where leaking area is. Clean area where you be welding and tack patch on every 2" then fully weld. No big deal. I usually use 1/8" thick...

Just to be clear the CR5 relay chatters only on dc + and dc-. When on ac all three relays work fine, no chattering, they just pull in like they should. Cover is off and I can watch them work.

Serial KG033217. Went to weld tig dc- today. Flip switch on and fan comes on fine, no issues then I push the pedal to start welding and CR5 relay chatters, shop lights blink like a dead short and no arc. Fan also slows. Pull cover and blow out, average amount of dirt, nothing horrendous. Try again,...
