Northern Tool is the dealer for NorTrack, which is a re-branded Yuchai. Circle-G Tractor and Keno Tractor are also parts sources as well as many others. See the dealer directory above.
The transmission and bevel gear case share the same sump, and use 85w-90 gear oil. Fill to the line on the dipstick. Do not thread the dipstick in when measuring.
Sounds like you have some broken steering clutch linkage inside. Check your parts manual.

Please be more specific. Having what kind of trouble? What is the machine doing/not doing?

Congratulations Grizz! :yahoo: :yahoo:
Segmented sprockets, real rock guards, swing frame covers, planetary final drives, a real powershift transmission with a torque converter, and no steering/brake linkage. It’s like I always say – “You have to go through hell to get to heaven”. No doubt you’ve already tried it out and found it rides much better too. That doesn’t look like a tractor seat, it looks more like a recliner :good: It needs a cup holder. A far cry from the ones I worked on in the ’60’s. You’re going to love it.

And depending on the type of soil you’re operating in, don’t forget to measure your track pitch every few hundred hours to check for pin wear.

Glad to hear you’re getting good service from your dozer too.
Surplus Center has a very wide selection of stacked valves.

If it’s just the aggressiveness of the hydraulics that bothers you, you can install 1/4″ orifice copper washers between the hose fittings. That tames it down.

The rubber track models have six track rollers per side. The steel track models have five track rollers per side. Consider this and how it will affect your performance. Aftermarket rubber tracks are available from a multitude of sources too numerous to mention (just Google rubber tracks). All you need is the length, width, and pitch. Also available from the dealers (including Northern Tool) at approximately $2,500/pair.

what fluid goes in the fill hole on top of the 3-point hitch piston box? AW 86 or 40?There is no such product as AW86 or AW40. Where did you get this information?
As David asked, does your tractor have a common sump?

Diesel getting into the governor portion of the injector pump does not necessarily mean the injector pump is bad. When this happened to me I determined that the fuel was coming from the lift pump actuator pin seal. I replaced the seal and it only lasted a few hours. I removed the lift pump and made a cover plate for the hole. There was an electric pulse pump sitting on my shelf so I plumbed that in and connected it to the fuse block on a circuit that is hot only with the key on. Works fine and there has been no fuel in the governor section since then. $40 for a lift pump vs. $500+ for an injection pump.
Exactly. My Mitsubishi excavator has no mechanical lift pump at all. Came from the factory with a Stewart Warner electric pump, and has been working well since I don’t know when.

If the Oil in the injector Pump was completely full and you r RPMs are racing, then you have a pump that is about ready to go out. The injection pumps only require between 4-6 oz of Oil. The best oil to use is ISO 100 Air Compressor Oil-If the Oil tank on the pump fills up again chances are you have Diesel leaking into the tank and you will eventually need to replace the pump
With all due respect, we have been down this road before. There is not one single governor manufacturer that recommends compressor oil, including Bosch, Stanadyne, and Woodward, and they all recommend 30w, 10w/30, or the same oil that’s used in the engine. I have been through the Woodward governor school in Ft. Collins and this topic was discussed to some length. There is absolutely no justification for using compressor oil. It just unnecessarily adds to the inventory. Cat engine governors are internally lubricated with engine oil, as are many of the Chinese diesel engines. The Woodward governors on EMD engines that I ran for over twenty years all ran 10w/30 synthetic oil. This isn’t rocket science. The compressor oil recommendation came from someone years ago because they were under the impression that the fuel injection pump acted like an air compressor. Well, we know that’s just not true. There aren’t any parts in a fuel injection pump that even remotely resemble any in an air compressor. You can also check the formulations and draw your own conclusion. Just because you have been doing something for years, doesn’t mean you have been doing it correctly.
In addition, just because the barrel and plungers are slightly leaking by doesn’t mean there is immanent pump failure. Pumps have run in this condition for thousands of hours.
Thanks for your consideration.
