JDcrawlers Messageboard

I have a front idler for a 440. It is worn and has had a few cracks welded, but it is usable if you are not planning to do a lot of heavy work. Make an offer. I'm in south central PA.

My right steering clutch slips and groans when under a heavy load. It runs fine under normal conditions, but if I really work it hard it will groan and lose power to the right track. Once it does this, it tends to slip more until I park it for a while. I'm gussing I need new friction discs, but I'm ...

Thanks for the help, everyone. Thanks for the manual, Paul and thanks for the TSX number, Chuck. Now I just need to get parts and see if I can get it running again.

I'm not aware of any differences - allthough I am not very familiar with the 420. The listings I have seen for replacement carburetors and repair kits group the 40, 420, 440 together, but list three TSX numbers. I'm not sure if that means that these are interchangeable or not. Actually, the number o...

The SN is 441200, which would make this a 1958 model. The local Deere dealer could give me the JD part number (AT-10181), but they were unable to cross reference it to the correct Marvel-Schebler TSX number. Can anyone narrow down whether it should be a 777, 768, or 756? The next question is can I j...

I appreciate everyone's input. The fuel supply is good. My dad has a 40, and we put his carb on instead of mine and it ran much better. It wasn't perfect, but the governor linkage is different, so we has to work the throttle manually, and we didn't adjust the needle valves to tune it in. What that t...

The number on the carb is TSX769. This model number was apparently used on some Ford tractors of the same era, but I have not found anything that references this number for the 440IC. I think it should be TSX 777, 768, or 756. I'm assuming that these are the same casting with different configuration...

I will try sealing the venturi to the carb body. I'm beginning to wonder if my carb was mixed and matched and the TSX model number is not what it was supposed to be. If this is true, I may have gotten he wrong rebuild kit. Is there a way to match the crawler serial number to the original TSX model n...

I double checked, and my plug wires are correct and the venturi is right-side-up. Any other suggestions?

Compression is good. I put a new power jet nozzle in the carb that came with the rebuild kit, so it is clean. I think the timing is right. I've actually tried adjusting it through the full range that it will run in, and the results are the same. The distrubutor has been apart and cleaned out and eve...

I having trouble getting my 440 running right again, and I'm hoping that someone can help. Here's the situation. I had a cracked head (small crack between the valves on one side). It ran ok but it started hard, missed while idling, and didn't have full power, but it did pull OK. I got a new head, an...

I have a 440 head with a crack betwen valve seats on one cylinder. The crawler did run before I pulled the head -- it just started hard, especially when it was cold. I have a new one on order. If anyone is interested in the cracked one, make an offer. I think it can be welded.

I've had this machine for ten years and the pedals have been locked together the whole time. I assumed that was the way it was supposed to be. The oil leaking from the reverser must have freed the clutch hub on the brake pedal shaft (it is the reverser and not the transmssion that is leaking). I gue...

My clutch pedal hub broke free from the brake pedal shaft (there is still some friction there, but it can move independantly), and now the clutch does not fully disengage when I put my foot on the brake. Based on the diagram in the parts manual, it looks like there is a woodruff key that keeps the t...

Does anyone have a good source for industrial yellow paint? The local dealership has it for $74 a gallon -- this sounds a little expensive. Is it available in spray cans?
