I have had acceptable results by putting the axle in a lathe, welding in a bead in the worn area and then turning it back down. Ground to the axle, not the lathe.

Lavoy,

What is the source of the loader decals? Do you know if the yellow version (for the green painted loader) would be available?

Very nice work BTW.

Swampy, If there is a fitting in them, you should be OK, I think. I've seen a 40 engine on a 420. A friend has one in South Carolina. Absolutly anything is possible. Other things that might help identify it - The 40 and the 56 420 were very similar. If the engine was swapped, the 57/58 420 would loo...

Should be no need for "vents". If they are tapped, put a plug in them. You want to keep all water out of those finals.

Gus, On a five roller - 1/2 to 3/4 in. of sag on each side of the top roller. 4 roller - 1 1/2 in of sag. 3 roller - 1 inch of sag. To remove them I'll offer a silly answer - As much as needed. You want to get the tension off the idler and that's maybe a 2-3 in sag? It would depend on how many rolle...

There were 3 different size JOHN DEERE decals for the hood, depending on serial number. Be aware that there are many poorly decaled machines out there as there owners are having the same problem you are. They just didn't know the proper location and style of decal, or just didn't care if it wasn't c...

Andrew, Here's some spotting features: The first year, or phase I, 420s used a modified 40 engine. The bore was increased from 4 to 4 1/4 inches but otherwise, it was a 40 block. The increase in compression and the resulting heat was too much for the thermo-siphon cooling system. A water pump was ad...

Chuck,

There are 4 bolts that attach the bumper from the back side of the support casting. Did you get all 4 out?

Congratulations on your new machine. I would love to have a 430. I do have a 420 with 90 loader. What part of SC are you in? I'm just out of Charlotte.

I think a service and parts manual would help you a great deal. Deere still sells them but at a premium. Lavoy may have some and they are availbable at tractors shows, ebay, etc.

Welcome to our world.

Never done it with a crawler as big as the 2010 but the pipe and board method works on the 40/420 crawlers. But sometimes the pipe will sink if you don't have a lot of them to distribute the weight and you are not on hard ground or concrete. You can literally push it by hand on the trailer so make s...

I'm in the camp of - I don't want to do it again.

I'd replace all of the items Lavoy mentions plus the bearings for the axle and pinion shaft and the axle seals.

If it's starving for fuel, as it sounds like it is from your description, check this. If it's original, there's a screen in the elbow fitting on the carb. Make sure that isn't clogged up as well as the sediment bowl under the tank.

That is way too much charge voltage. Somethings not right there.

Unique looking machine with that homemade sheetmetal. I've not ever had much luck unsticking clutches. Usually have to rebuild them.

Very nice, thanks for posting the pictures.
