Hey guys so I changed the Oil on my B7100 and it’s leaking not a lot just a little bit and we put new cylinders on the tractor about December-January the cylinders are for the Loader and the cylinders are leaking we put new cylinders on to fix this leaking issue because the old ones were leaking and now the new cylinders are doing the same thing

The leaks are inside these two knuckle fittings I replaced the blown O-Rings the cylinders are only leaking under pressure like getting scoop of gravel and I didn’t buy the cylinders my Grandpa did before he passed this is his tractor…… He bought the cylinders off of Amazon and the oil leak is under the nut where the oil is it doesn’t leak a lot just a little bit and we tightened the nut and new filter and it still leaks, the leak has only been here since I changed the Oil about a month ago

Those are hose fittings. The fittings are leaking not the cylinder.
