  1. 2+2 hydraulic troubles

    I'm having hydraulic troubles with my 6588. I can't seem to get more than 9-13 gpm at 2450psi from the hitch pump at the motor control valve outlet. The tractor has fresh hydraulic filters with the bypass installed between the two elements, fresh hytran (slightly over full), and fresh spin on hydraulic filter. I have cleaned and inspected both orifice screens behind the hitch pump signal line and behind the 5/8 plug on the pump. I have also cleaned and inspected the orifice on the inboard side of the auxillary valve mounting block. When under load, the hitch pump may make no noise at all, or it may load the engine slightly and make noise something like it is cavitating and trying to pick up oil, but only for a few seconds, then nothing again. The tractor was running a grain cart prior to my purchasing it. I'm trying to use it on a hydraulic push off manure spreader. It worked for one load, then was unable to really do much more than start the next load. In a related, or perhaps unrelated vein, the hydraulic clutch assist rarely works, the transmission brake is only moderately effective, and the TA doesn't shift. I think it stays in low side. I have removed and cleaned the solenoid and spool valve that operates the TA. The TA spool is moved up and down by the electic over hydraulic actuator, but the TA doesn't shift. If the selector is left in the high side, the solenoid gets too hot to keep your hand on it. The low pressure warning light is lit on the dash. The TA worked when I got the tractor, and I dont remember the warning light being lit, but after a healthy pressure washing, my TA troubles surfaced. Also, having little experience with 2+2s, I wonder if it is normal for the MCV pump on the belly to sort of chatter and pulsate pressure? This one sounds something like the pulsating noise from a boxcar magnum. I'd appreciate any insight or direction. Thanks
  2. Quest is over, 6*88 2+2 showed up

    Finally ended up with a 6588 after looking for one for a few years now, tried to buy a few over the years and nothing worked out. This one came out of Iowa and is a good starting point. Lots of older 2+2's around but I wanted the later control center on the 6*88's so it limited my choices. Well, search for the tractor is over, now the search for parts starts.
  3. 6788 2+2

    Hi All! I've been using this site a lot, but this is my first post. So I grew up running the 2+2 tractors as a kid, and now have a 6788 that I want to restore back to its original paint, tires..... I bought this tractor in Montana and the history on it says it came from South Dakatoa. The tractor is straight and runs good. It needs a new seat and I want to make sure I replace it with one that looks original. From all I can tell, this is the original seat, it is grey, and the the rest of the interior is Western. Is that right? (see pic). The other question I have is about the steps. These steps look more like the 3588 step. All the other 6788 tractors I have seen have the black step that looks more like 5088 tractors. Was IH using up old parts? I know its a lot of questions, but where is a good place to buy new decals and the black vinyl over the back of the cab? Thansk everyone!
