I need to buy fittings for the cylinders on my loader, but don't have access to them right now to know the correct size/type fittings to get. I think I need pipe threads to screw into the cylinder and female o-ring to screw the hydraulic hose onto? I think it is standard 3/8 hose from tractor supply? Does this sound right? What sizes on each end?  |

I'm pretty sure the cylinder fittings are NPT. Our Tractor Supply only has hoses with NPT ends. The fitting shown is a NPT swivel. ------------- 1970 190XT, 1973 200, 1962 D-19 Diesel, 1979 7010, 1957 WD45, 1950 WD, 1961 D17, Speed Patrol, D14, All crop 66 big bin, 180 diesel, 1970 170 diesel, FP80 forklift.

I looked at my 400 and all the hoses had 3/8 NPT male ends. Some were swivel ends. Fixed ends can be used with the swivel adapter. I am pretty sure the 500 uses the same type hoses, at least according to the parts book. ------------- 1970 190XT, 1973 200, 1962 D-19 Diesel, 1979 7010, 1957 WD45, 1950 WD, 1961 D17, Speed Patrol, D14, All crop 66 big bin, 180 diesel, 1970 170 diesel, FP80 forklift.

| Yes. all 3/8 NPT on cyl's of both the 500 & 400 that I have. I know the 500 has 1/2 steel lines on the boom to the front tilt jct. I think the 400 also but have to look for sure. I moved the front jct's on the cross over tube for the bucket cyl's to the top of the tube vs the back. On a 180 so the starter wt didn't interfere. I do not care for the hose arrangement and as the hoses need replacing, I am putting steel lines from the jct back to the base of cyl's and basically short straight length of hose for the little flex it needs....Dale |
