D14 Hydraulic Problem

YTSupport · Aug 6, 2020

I was working the tractor and suddenly it would not lift. I checked the hydraulic case and it was empty, so I filled it again, it lifted for a few seconds then dropped again and the case was empty again. I got suspicious seeing no visible signs of leakage and checked the PTO case, it was overfilled by about double.

Makes me think there is a leak at the ram. Does that sound logical and can that be serviced by just removing the PTO case. Never been in the back of one of these but that seemed like the correct approach. Would like to verify with someone who's been in there.

By PTO case do you mean the trans/rear end oil level? Yes, there is a hose going from the external remote valve connection, into the lift cylinder. That, and/or the cylinder can leak hyd oil into the rear end. Given the sudden, catastrophic hyd oil loss, the hose probably gave out. Yes, pulling off the rear cover gains access.

Excellent Bob, thanks for the info. That's a much quicker job.

The Transmission and PTO sections have a separate casings so I was just differentiating, the rear most casing is what I meant. Yes the one with the remote mount. Very unfortunate timing, we have only two smaller three points and the other tractors are too large for most of our small implements. Plus I have a D17D rebuild tying up the bulk of the shop. But if it's just pulling the rear case, I can back it up to the shop and get it done before worse weather comes in.

Always replace both the cylinder packing AND the hose while it is apart.

Thank you Dr, I will do that.
