It should have 4 push rods in a 2 cylinder. Sounds like you need to drop the pan and find it (or the pieces).

I ran a UTHF meeting the John Deere J20C (Hy Gard spec) in my 430 with now issues. It is nearer to a 20weight engine oil. If you are concerned about extreme cold use the Low Viscosity grade, J20D.

Give Larry a call (701-361-1006 during Central time business hours). He has had parts for these in the past and can give you a lot of info on them.

Starting a new thread of your own can often get more attention than the tail end of an old thread.

Did you get the two manuals I mentioned? You will want them before starting adjustments. I believe those are wet steering clutches. There is no actual adjustment to the steering clutch itself, only linkage adjustments. The steering brakes are also just linkage adjustments. Pressure checks would be t...

The John Deere 435, diesel version of the gas 430, was the ag tractor that had the 2-53 as the OEM engine. The 440ID was the industrial version of the 435 with the 2-53.

Make sure the shaft was drilled completely through. some might only be drilled from one side. Just something to check. Pull the bolt out and run a wire in or pump some grease in the fitting and see if it comes out the bolt hole.

I am going to say you do not want to mess with the finger adjustment in place, if you can even get to them. Most anything could have or not been done in the past. What you posted says there are many unknowns of what exactly was replaced before and if the work was done completely and correctly. My th...

Try connecting one hose to the other making a loop. Both disconnected might be stopping a return to the reservoir. I say this without knowing how the backhoe is supplied on your crawler.

Use some flat bar to make some. Cut the pieces a couple inches long of the appropriate width to set on the rail flange, thickness based on the bolt size. Drill and tap the size/thread hole you need in the center. If you want them to float, use some sheet metal pieces to tack to the frame rail and be...

I will suggest if and when you get to rebuilding a steering clutch you call and talk to Lavoy. His business if rebuilding and selling parts for these early crawlers. He uses the parts in his business and will have quality parts and can give you advice if you need or there are problems. Try getting t...

Your description (steering issue and the drifting right when pushing straight indicates a bad right steering clutch. If you have done a full adjustment step by step as in the manual and it still acts the same, it is most likely you need to rebuild that steering clutch and brake.

It may well be that. If so there should be a wire end either where the coil should be or at the ignition switch if the wiring diagram shows a resistor on the switch or a resistor wire going to the coil.

Any quick couplers on the hydraulic hoses anywhere? If one is not completely plugged together that could block the pump flow depending on location. With the crawler battery cables attached, try running a good booster cable from battery negative to one of the starter mounting bolts if you can. Run th...

If you think the issue is hydraulics, start by making sure all the hydraulic control levers are centered (in neutral if you will).

Don't be surprized if this thread gets moved to the Late Models Board where threads on the 450 belong.

Look at the 10-hour daily checks and filter servicing.

The transmission has a dipstick. The Hydraulic reservoir has a site gauge and is located well above the transmission. They each have their own filtration systems. They are separate systems.
