With the same equipment, probably a thousand heavier, loader maybe a little more.

They are hard to come by, I have been planning on making new couplers and the splined shaft, but just have not had time. If yours is bad, let me know, maybe I can get one done quickly.

Engines will swap no problem, engine clutch kits are $200.

If your straight pipe will be above the hood, then you can probably reuse it, if not, I have the adapters on hand.
The early 420's used the flanged muffler like the M/40, but it is not obsolete. The later style muffler just clamps on to the adapter pipe.
I have mufflers on hand as well.

Shannon,
Not that it is not possible, but that engine is plentiful enough, it should not have been necessary. I would guess that if it is a cobble job, it should be readily apparent.
Lavoy

On a 40, it will be tough, on a 420 if you have the short stub exhaust pipe, and then the muffler goes over that, then it is easy to remove the muffler.
We usually put the loader in the air, and clamp a heavy piece of angle iron on the ram so that it can't fall down if someone hits the lever.

I got two samples, and that was the end of it. Was never able to get pricing or anything else, so just gave up. If anti-weized, the original ones will never cause any trouble.

Most likely the pump drive coupler, possibly something internal, but would check the drive first.
Lavoy

Shannon,
I think that the serial number on the engine should give you some more info, that engine is/was used on a lot of applications. Some at higher horsepower levels I think and turboed.
Lavoy

Fibers are almost impossible to clean, before I had new ones available I used to use a wire wheel in a grinder, but you can remove some of the disc that way too.
The steels discs shouldn't be hurt with a wire wheel, if you blast them, should probably be a bead blaster to keep from warping.

The All-Green crawlers were the 1956 model year, beginning at serianl number 80,001 going up to 94,818.

Well, looks like we are up to 38 members, and gaining a couple per week. Hope to see it go higher, and welcome to all of you that have registered.

I don't know of any specific to only crawlers, but J.R. Hobb's wrote a book called "The Little Giants" that was about the Dubuque series of tractors, and it has a fair amount of info on the two cylinder crawlers. It is out of print, but I would guess you could find a copy on the web someplace.

Pair of rails with new pins and bushings is $1500.
I might have a used adjuster on hand, not sure. If nothing else, I have new replacement adjusters available.
Lavoy

I assume you mean undercarraige? I can rebush you a set of tracks, we should have enough used rollers, and either new or used sprockets depeding on serial number.
