I've ran into a clearance issue on the D180's rear hydraulic hose at the rear of the lift cylinder for the 3pt. The link that joins the cylinder piston to the main arm on the 3pt rock shaft uses 3 holes and a welded plate between the two side sections. That plate allows the cylinder to push against the rock shaft's arm and move it rearward, but - the lower end of that plate hits the cylinder hose's 90* fitting when the lift is lowered all the way . The link only goes one way with the plate joining the two sides facing more downward than up - it's offset from being centered a bit. The 3 holes in the link allow the rear 3pt to float, if you pin the center hole it locks it solid and allows for down pressure to the 3pt lift. Simple enough design, but not sure why it wants to hit the cylinder hose's end fitting - it's wrecked the swivel on the hose and caused a bad leak. I got a new hose from Lowell, but the modern replacement hose ends are taller than the original ones from WH, so it interferes with the 90* fitting even worse - see the photo and the mark where it needs to be cut out for clearance ..couldn't get a pic of it on the tractor - that seat frame is seriously in the way of these parts. Another not so fun part to work on a D due to it's frame design...ugh. The marked area is where it it hits that 90* fitting, badly. Aftermarket ends, as I said are even worse as they are a little taller - generally around 1/4" difference. I suspect WH specified aircraft rated low clearance fittings on many of their hydraulic hoses - it's not the first time I've ran into clearance issues , especially on the older models when replacing them with new hoses. Not sure if there is a new hose from Toro available - but it has an interference anyway with the linkage... Has anyone else with a D ran into this issue with clearance to the link - or was this welded incorrectly from the factory somehow ? Second thing - it seems many of the older models that used any hard steel lines used SAE 45* flare ends. Newer equipment uses the more common aircraft JIC 37* high pressure flare instead - it seats easier and can better handle the pressure. Are the steel lines on mine correct, or has someone changed them ? Ends appear to be common 5/16" SAE flares on these steel lines, it's tough to adapt modern hydraulic lines to them versus using JIC flare ends. I think even the S bend twin steel lines that go into the implement ports on the pump are the same size fittings and same SAE type versus JIS. I do remember that being odd when I had the pump out for it's repairs and all those parts looked original. A lot has been screwed with on this tractor over it's lifetime, common to see but I'm not sure just how far they went with some areas, I want to keep it correct. The old line sealed fine to the SAE hard line end below the seat - it's a 700psi system so it's fine, really. Other than the leak - the 3pt lift is super strong and had no issues other than not wanting to stay up for long due to the 90* fitting puking oil... Sarge
