I'm purchasing a 1979 Hough IH H-80B and waiting for it to be delivered. It has no brakes. I've searched the forum and I cannot find anybody explaining much about the H-80B or a good source for parts. If anybody knows, I could sure use a source. Also, doesn't anybody know if there is a Dresser equivalent to the H-80B?
The H-80B uses a Navistar DT466 rated at 200hp. The machine runs well and the engine has been rebuilt.
Known issues that I discovered in an inspection:
1) A number of gauges and lights are inoperative but given the state of the wiring, I'm willing to bet those things will wake up if I replace the harness. I have an auto tech background and do not see replacing the harness one wire at a time to be a problem other than my labor.
2) There are no brakes. Air pressure is there with several minor air leaks. I ordered a Sunex 22-ton air jack, as well as a pair of 22-ton jack stands so I will have what I need to pick up an end and remove wheels to get at the hubs. On the other hand, I've read online that many of the braking problems are hydraulic issues and that these things tend to have wheel cylinders that fail. I need a source for parts.
3) The giant seals between the pins and the cylinder rams are failing and need to be replaced to keep the grease in. I need a source for parts.
4) The throttle cable is super stiff. I was thinking of taking it off and measuring it, but don't know how long the equivalent Dresser cable is or model application. I'm wondering if this is like boats: you can be a little long control box cables, but you're SOL if they are too short. Does anybody know of a source for parts for a cross-reference?
5) My seat has sort of dissolved. Any chance of finding the right vintage seat or should I throw down and plan to pop for a universal tractor Sears air seat with 5" of travel?
6) The third function level is disconnected but the top line of the third function is leaking at the four-bolt plate where the line comes through the upper frame. I presume this is because the disconnected spool valve is not centered or does somebody know something I don't know?
7) The bottom of the bucket, while not thin, still needs some grinding out and welding in of replacement plates. I plan to plasma cut out new parts and replace the edge and then go at it with a bunch of 7018 rods to sort it out but I've never done this kind of work before. Any noobie suggestions?
8) The right side door doesn't latch. I dunno why but I haven't looked at it closely either.
Thank you ever so much for your time. This is my first really big machine so assume that I'm fairly handy, but ignorant of heavy equipment like this apart from YouTube University (which has nothing service-related on these machines near as I can tell). Here is a photo of the machine I'm purchasing.
