    I do not have a schematic of a 186, but I do have that of a 1510 so it should be very close. I also will include the wiring to the back of the ignition switch of the 1510.

    Since, were on the 186d here, I'm trying to resurrect my 186d. (it has 12000 hrs on it) For some reason, oil is not being pumped to the hydro gear pump for the 3pt lift. If you guys have any experience on this, I'd like to know.

    I'm just about ready to pull the transmission hydro circuits and see if there is some blockage that is preventing oil from being supplied to the gear pump.

    What I'd really like is a diagram of the transmission area that shows how the oil moves from the trans to the gear pump back to the 3pt lift.

    With any luck, I WILL get answers.

    BTW, 3 gear ranges and a 3sp auto make this tractor one of my all time favorite work horse. Steering sucks though, high maintenance.
