How does a thread about PTO installation manage to morph into one about clap......or was it clapping...... I don't know anymore because I sorta got lost along the way.
Rear PTO kits that used steel supply lines were issued for both the pre-79 short wheelbase models and the post 78 long wheelbase models. This means that the lines for the later units are two inches longer than the earlier ones. Obviously, you cannot expect to install the early kit on a late tractor or vice versa.
If your kit has hoses instead of steel lines, then you can shorten or lengthen them with a bit of creativity or if you do have steel lines and the wrong kit for your tractor, then you can change to hoses. Just don't throw out the lines. Seal off the ends and store them in case you decide to sell the PTO later on.
Installing the kit is a simple task and shouldn't take you more than a couple of hours max. Take off any attachments first, including decks. Don't worry about the hooking up the PTO valve first. Instead, go under the tractor and remove the high pressure hose coming from the pump, right at the point where it attaches to the travel/lift valve. Once that end of the hose is free, install the appropriate steel line or hose to the IN port on the travel/lift valve and the other hose or steel line to the now dangling hose coming from the pump.
Snug those fittings up but don't tighten them. Go to the rear of the tractor and attach the line coming from the pump to the IN port on the PTO valve and the other line to the OUT port. Again, snug them up for the moment. Now is the time to position the valve's mounting bracket where it should go and bolt it down solidly. With the valve now mounted, tighten all fittings, start the tractor, check for leaks and top up the reservoir. Congrats.... you're done.
When working on hydraulics, cleanliness is paramount. Flush any hoses or lines before installing. Seal off the end you are not working with by applying tape over the end to make sure no dirt gets in accidentally. It only takes a spec of material less than 1/8" in size to create problems in certain areas and none of the older tractors are fitted with a filter.
When testing the system after working on it, wear safety goggles. High pressure oil in the eye can result in blindness.
mg: :fing20: What a sissy! This really isn't a tough job although you'll have to wash your hands when done. A PTO sitting on the bench isn't of much use.:00000060:
