2130 Hyd. Failure

[Farmer1]

My 2130 tractor made noise when I started it this morning and I have no Hyd. and no steering, rockshaft,ect.. It worked great yesterday and for the last year that I have had it. I looped supply lines uder shift cover to bypass pto and shift cover and had lots of oil flow. I removed hose at top of oil cooler and oil doesn't come out there, but it comes out of resevoir tank above air filter. I was sure it was supposed to run the other direction. Is there anything that would cause this. The noise by the way come from main pump, I presume from not getting oil its not a cavitating noise but more sounds like a cold hydrostatic transmission. I am going to check flow control valve next. If the destroking valve got stuck would it cause this? Any ideas would be greatly appreciated for I am stumped.

First check and see if the main pump is turning. Many times the coupler strips the internal spline and quits driving the pump. the reason you have oil out of the reservoir, is that the charge pump in the trans is pumping oil to the main pump.

Thanks that was the trouble. Out of curiousity, isn't the oil supposed flow from the transmission through the bottom of oil cooler out the top and into the storage tank about air cleaner? I was sure that was the direction my 1830 flowed. Anyway thanks for you help.

No oil flows to front pump up to reservoir through oil cooler and back to trans.
