- Kubota M59, JD530, JD310SG. Restoring Yanmar YM165D
The suction hose is the large diameter one. The JD tech told me that the 310 hoses usually begin to crack on the ends along the inside diameter first. He thought it was due to the hot oil. Cracks run perpendicular to the worm drive clamps and beneath them. So you won't see the cracks from outside. What you see is that it begins to leak and drip when sitting.
To replace it he raised the 310 up on the outriggers and turned the engine off. Said that the outriggers have a fluid lock so that they will stay up indefinitely. With lots of room then, he crawled under there with some buckets and to my surprise simply drilled a one inch hole in the lowest part of the hose! He said since he was going to replace the hose anyway, that was the simplest way to drain it. JD recommends their own 5w-30/40 motor oil as hydraulic oil so we put that in with the new hose.
But after a cold snap I believe the lo-viscosity winter Hy-Gard is a better fluid.
On the chirp, I don't know. But there are a zillion 310s, and some really good 310 mechanics at the yellow JD dealers. It wouldn't surprise me if they could diagnose it from your video. The shop I work with is real helpful like that.
