This could be a good place to get information, but we don't know what kind of loader you're working on, or where you are located, filling in your profile would help a lot.
I broke one of the fittings in my 60 in. MMM and borrowed one out of my FEL to grease the MMM. When I went to replace the borrowed fitting, I assued that the Kubota loader would have metric fittings, so that is what I bought at Tractor Supply. When I went to replace the fitting, I needed the standard thread fitting. If we knew what you were working on, someone could possibly let you know what you need and where to get it. Tractor Supply also has the tool to remove broken fittings. Since you didn't fill out your profile, all this info may be totally useless, but I wasn't doing anything else anyhway.. /forums/images/graemlins/grin.gif
