Looks like a 1020 Unit Crane, probably a 371 Detroit power. 10 stands for either 10 thousand pounds capacity or 10 tons, I can't remember. The 20 is for 20 cubic feet or .75 yards capacity for digging or for a shovel front. Years ago when I started driving I was loaded many times by a 514 Unit with a .5 yard shovel front. I learned how to back under it, you had to be spot on. It had a very smooth running straight 8 Chrysler engine. The Ford probably had a 332 V8 which was a common engine in that vintage truck. I don't know what the difference between it and the 330 other than the 330 is newer. DWF

I had a 73 TD15-C crawler with a DT 466 engine that I bought in 1994. It did not have the coolant filter that has additives for anti-cavitation. I never at that time knew anything about additives, so it was just ran and probably changed anti freeze once due to a leak. Ran it until 2007 when I junked the 15C, not because of the engine but the rest was shot. So I ran it 13 years without doing any more than normal oil changes. DWF

218-757 3911 is the phone #

Go to Cusson, Mn on Hwy 53 just north of Orr, Mn. There is a sawmill there. He used to sell Tamarack probably still does. Cusson Camp Co. if I remember correct is the name. DWF

Good to hear you had success! I had a 74 TD-8E for over 20 years, had good luck with it. DWF

I suppose it could have hydraulic brakes, but most heavy trucks like that came with air brakes which would be much better. DWF

22.5 will mount right on. You will need 11.5X22.5 to match the diameter of 10:00X20 and 10.5X22.5 to match 9:00X20. You should not run the 22.5 on the same hub with a 20 wheel. DWF"

Not much grip with those tires. DWF

Red Power, Antique Power, Legacy Quarterly (Massey Farris and Ferguson). I like them all. DWF

That's usually how that works like D_F_P said. DWF

If the oil he has been using meets the HyTran specs, it should be okay. DWF

777 has not been on the forum for almost 2 years. Too bad they don't post back the results. DWF

You have to break the track and then slide the idler out enough to get the cylinder out, hopefully it's not pitted to bad. DWF

Happy to see you got it saved! Good deal! DWF

The only brake is the two pedals on the floor and make sure it is in neutral and clutch lever ahead. I suppose the brakes could be rusted to the steering clutches, but you would not think so being it's been inside. DWF

Maybe a 91 series has a push button start? Just a thought. DWF

Thanks for the update! There are a lot of us that just like when things are repaired properly. DWF

Hector said he found the filter and to email him. He has his email on his last post. I have a friend who got some Allis parts from Hector. He had good luck, but Hector wanted to do business by email because of the language barrier. DWF

I had a TD-15C for quite a few years. Always used regular green anti-freeze. I had a tilt on the blade too, can't remember for sure, but probably used AW-32 hydraulic oil. I can't see why you would need anything special for the tilt, 10W would work too. DWF

Very nice pair of IH manufactured trucks and tractors! DWF

Yellow bucket hydraulic transmission oil is usually associated with cheap and or inferior oil. The only oils that are together on that machine are the steering clutches and gears are together. Transmission is alone on that model, newer ones are with steering etc. DWF

Transmission would take HyTran or a good generic brand (no yellow can) same with the steering clutches, Hydraulics 10W emgine oil, or AW32 hydraulic oil, finals 80-90 gear oil. engine oil I would use 15W-40 or a straight weight, green anti freeze. I had a 74 TD-8Efor years, a great machine. Late 70's they changed transmissions. DWF

Glad you found something that should work for you! Good luck with it and thanks for posting back. DWF

1959 for the 92 series, I had Serial number 706, probably the 205th one made. DWF
