    IH460U dripping hydro fluid from steering valve

    Looking at the video I'd guess my o-rings on the thrust washer on top of the control spool are worn. Mine actually leaked at the steering wheel nut when I put a dab of wet silicone in the weep hole, but only after it gets sufficiently hot. The video shows all the lines are used but mine has an...

    IH460U dripping hydro fluid from steering valve

    I have slowly been fixing the leaks in my work tractor but it unfortunately developed a new, worsening one. The power steering control valve that the steering wheel/shaft goes through is leaking from the plug. It appears that the plug was designed to have a hole it it to allow the leaking fluid...

    460 Gas running hot - temps?

    So far this flush procedure has kept temps in check. Typically running below 200 and I dont think its went over 205 yet. Seems like a win to me.

    460 Gas running hot - temps?

    75 out yesterday and I ran for hours and it didn't go over 210, dropping to 205 downhill or flat. I found a few tubes are clogged hard, freed up a few as well. Still in the flushing process and getting muddy looking water out. Tried to build heat last night when it was cooler and...

    460 Gas running hot - temps?

    90% of my running is at 1/2 to 2/3 throttle, no lugging at all. I can run pto speed and higher with it still running hot. I'll validate timing again and then see if rad flush helps any and go from there I suppose.

    460 Gas running hot - temps?

    I can do that much. Thats why I'm going the oxalic acid route, plus I don't have to remove the entire rad, pay them to potentially poke holes in, which I can do.

    460 Gas running hot - temps?

    Yes, but that would involve stopping, shifting then on flat/downhill shifting again. I'd have a clutch worn out in a year. with TA pulled back there is very little lugging.

    460 Gas running hot - temps?

    Yup, pressure washed it last year. It only run at most 210 last night but it was only 55-60 out but I was mowing pretty fast in 3rd and 4th gear, using the TA when RPMs would drop. Running 3 hours with dish detergent in the rad its brownish colored so it is cleaning. Saturday will be the...

    460 Gas running hot - temps?

    Cleaned and pressure washed last year so its clean. I thought the tstat is 190 so it should run 190+. I'd rather fool around with chems than take it out, have the rad shop charge me a boat load and then not guarantee their work. I've already called around when I had another brass rad leak...

    460 Gas running hot - temps?

    I think its 1850rpm/540, I should remember I just got done running it for 3 hours straight. Only ran up to 205-210 but its only 55-60 out today. I did add cascade to the rad to clean, then will run the oxalic this weekend, flush/nuetralize then add new coolant and see. Plugs are Autolite...

    460 Gas running hot - temps?

    Thank you for your detailed response. I did try 93 octane last year and don't believe it made a difference so I went down the cooling system/timing route. I can't recall timing settings but I did check total timing at high idle as I found online. If you know off-hand can you remind me I...

    460 Gas running hot - temps?

    A 5# cap would put it closer to 230 without boiling. I believe the gauge is accurate, it matched the guess-o-meter that was on it before. One thing that I didn't verify is the lower rad hose collapsing under high RPM. I can't recall if it has the spring in it or not.

    460 Gas running hot - temps?

    I use my 460 for mowing with a 7 foot flail. It works well and run it at half to 2/3 throttle. The temp will climb though after running for a while up to 230 but doesn't boil over. I replaced the water pump and tstat and gauge last year and also used an auto parts store flush. Can't really...

    Fixing deep ruts

    This is exactly what I have. Single rear roller. Teeth only cut 2-3" deep at most and are 5/8" square.
