Transmission/Injector Pump

[Rambo]

Hello,
I was just wondering what kind of fluid goes in the transmission? I put hydraulic/transmission fluid in it and now it's leaking from the rear of the PTO. In which where would you connect a mowing unit? I seen on one post where somebody used 90w gear oil. Just wondering if the hydraulic transmission fluid was too thin or could it be a rear seal? And also what is the injector pump and where is it? I looked on the right side from what I have read on some of the posts but I have yet to locate and what does it do?. The tractor is a 1610TS. Thanks for any reponse. Rambo/NC

I would not recommend 90w. I would replace your seal. I don't have the oil spec for your tractor, but any transmission being used as a hydraulic sump should be utilizing a blend targeted to meet both the needs of the hydraulics as well as have high pressure gear qualities to protect the transmission. General purpose hydral / gear oils usually come in a summer and a winter weight. You may have the winter weight, which may be a little light depending on your application. The other possibility is to ensure the breather is not plugged, as that can be a problem.

By the way, your injector pump is the unit on the side of the engine that injects the diesel fuel into each cylinder. The injector pump is a sensitive (and very expensive) item. While it looks robust, it can be damaged by water in your fuel or any type of contaminants like dirt or dust. Internal tolerances of the injector pump are quite critical. ALWAYS spend the time to empty your water separator and change your fuel filter. It will last the lifetime of your tractor if cared for. The injector pump is driven by the engine and controls the timing. Don't loosen it, remove it or open it up. While you can time a pump without sophisticated tools, it isn't a job for the uninitiated. Try not to run out of fuel, as priming certain engines can be challenging. Most engines (that are not self priming) require a full tank, cracking the fuel primers (one or more on the filter(s) and / or injection pump) until bubbles disappear. One of the easiest ways to prime an engine is to crack the top of all injectors with a wrench, have someone crank the engine and tighten each one once it begins to spray fuel. It makes a bit of a mess, but does work. I modified the fuel cap on my old Ford Super Major with an air valve. When I ran out of fuel, I filled it up, cracked the bleeders and put a couple of PSI in with a hand pump. Really worked well.
