Serial number breaks (not build years) in the parts catalogs are usually where upgrades show up as changes are made to parts used during production runs. Sometimes a Technical manual may reference the serial number break, if the procedure changes because of the related part change. The 650G parts ca...

Welcome to the Boards. 650 is the model G is the series. In your serial number the TO means it was built at the Dubuque Works. 650 is the model, G is the series. The parts catalog doesn't show what H designates, you may need to ask your JD construction equipment dealer about that letter. That positi...

Welcome to the Boards. The aluminum base of the rectangular "glass" filter is bolted to a metal bracket which bolts to the head, it is not a direct to head mount. I think everything will bolt up, worst case you might need to make a different bracket. As far as lines they should work. I think they ma...

Welcome to the Boards. You have been looking at videos of the older machines with dry steering clutches, that do not apply to your 450C. A 450C has wet steering clutches and brakes, they run in an oil bath. The clutches are operated by hydraulic pressure, not mechanical linkages like the dry type. T...

Welcome to the Boards. Machine serial number tag breakdown using the 350 Introduction from the JD 350 Parts Catalog: SN = serial number T = Tractor 4 = JD350 F= Crawler - Dozer 3 = Diesel D= (Transmission) Sliding Gear with Reverser Serial number: 101129 (This number falls in the 1969 build range us...

I don't see pulling it as an easy way. Tighten the belt up. Then push in on it with one hand as you turn the fan if needed. It should turn if the plugs are out.

Both tracks spin so the steering clutches are engaged properly to begin with. Now for the rest of what I suggested and asked. The next part of that was to pull the left clutch, while it was spinning, and see if the track stopped. How far did it pull to disengage? Then do the same for the right track...

Remove all 4 sparkplugs so you are not dealing with compression in any cylinder. You should be able to turn it with the fan, with the plugs out. Make sure the belt is tight and you might need to push in on the belt as well. Be sure to turn it in the correct rotation. If you want to get it close with...

Welcome to the Boards. On the housekeeping side of things, don't be surprised to find a moderator has moved this thread to the Late Models Board, that is the board questions about machines starting with and following the first 350s and 450s are normally kept. You have a 450c, the A designates it as ...

Welcome to the Boards. You are working on two different steering systems. Your 450C has wet steering clutches. They do not have pressure plates and throwout bearings in the steering clutch system. They have hydraulic pistons which are engaged with hydraulic pressure when the engine is running. They ...

I think you jumped a line on the description side. AT13989 is the radiator cap, the radiator part number is AT13096. The manual is likely correct, however that radiator only applies to a few of the 1010 crawlers. A couple pages further in the parts catalog they show other radiators used on the 1010 ...

Thanks for updating the thread. It may help someone in the future.

To post pictures you need to use a third-party hosting site like Imgur or Postimage. Those are both free as far as I know, and there are others. From your description of, the pump is right behind the radiator, that sounds like what is the referred to as the camshaft driven pump. It works fine for th...

Welcome to the boards. There is not a yes or no answer to your question, as such. Do you have a blade, loader, or neither in addition to the backhoe? What is the backhoe? Do you know the recommended pressure and flow for the backhoe? Have you done a pressure test to know what the current system reli...

Once and a while you win.
