It is leaking hyd oil at the remotes when I plug in a hose is there o rings in there and how do I replace them or is that the way to fix em? Thanks

Yep, o-ring. With a pick get the old one out and lube the new one and fit it in there. It's as easy as it sounds.

If you can find them, I believe you should use 90-durometer O-rings not the 70-durometer found in many generic kits. They are harder and will last longer.

This is what you need

I bought a pack of 100 the sq profile -117 from McMaster, item number 4061T163 for less than $10.00 plus shipping a few years ago and replaced the ones in my 6640. I have not had any to leak since, but if I do I still have 96 in a bag put up in the house. Durometer is 70 instead of 90 but like I said, I have not had any issues.
