IH 3514 FIXED

[Brian ke]

Hey thanks guys for the help and information. Just letting you know that I removed the control valve (the one that connects the foot pedals to the transmission; my repair manual says this is the control valve). It was dirty so I took it apart and gave it a bath in diesel and scrubbed in real good. Replaced the gasket and o-rings and topped off the oil. Runs great now.

Don't know if it was the o-rings or some debris in those little squirt holesin the valves. It did leak a little and o rings were crushed.

Anyway I am still trying to find access to the center section for those relief, check and shuttle valve????

I guess you can forget the center section. That would apply to a hydrostatic transmission like used in a 656 and you for sure don't have that. I just dug out an old manual for a 3414 loader tractor and yours sounds very similar except this one shows it has 6 gear selections. You had me confused as there are foot operated hydrosatic transmissions but the farther you push the pedal the faster you go. On a shuttle drive the pedal moves shift valve and engages either the forward or reverse clutch pack and is coupled with a torque converter.

Thanks Pete. I am still confused. I bought repair manuals and it said I had a 656 on the 3514. I do have foot pedals (forward and reverse)that speed the engine the further you push. I also have 4 forward gears that I guess work in reverse. Don't need to go 20MPH in reverse so I never have used the high gear in reverse. Probably that is why the manual doesn't make since to what I am seeing on the tractor, although some of the pictures are correct. One book I have does say torque converter and shuttle transmission model 3514 and 3616. I suppose that is what I have. It makes since now because it tells me about the control valve and how it ports oil to the torque converter. I will ignore the 656 book. Confusion gone. Seems this transmission is less complex than the 656.

Do you know if the transmission tank should be vented? I have received 1 yes, and my buddy said yes (makes 2). I have a solid cap with a dip stick that seems to be right, but I can't seem how it would vent. My oil seems to be somewhat foamy and a tan color.!!!

sounds like it has water in the oil which would be normal if not changed for a lot of years(condensation).
new filters and oil would be a smart move
if still foaming then getting air somewhere
good luck

You do indeed have a vent but I cannot tell you if it is supposed to be in the cap or dip stick or someplace else on that machine. Does sound like you have moisture in system though unless it is perfectly clear when shut down and foams up when running, then you could have a suction air leak or restricted filter.
