Does anyone know what size nut holds the piston on the bucket tilt cylinders? I am needing to replace the seals in both cylinders and want to make sure I have the right tools.
Welcome to HEF, R.Bragg ! #17 is the bolt.
Thanks Tinkerer, I have a 3/4" impact and some impact sockets, just wanted to make sure I would have a socket to fit. I appreciate your help!
It should require a 1 1/8" socket. Depending on how much loctite may have been used on it in during assembly, sometimes a little heat is required.
I could be wrong, but on our 580c, it seemed like it was close to 1 3/8 , 1/2, or 5/8. I know we used the 3/4 inch drive and a breaker bar with a pipe for an extention.
Thanks guys, I figured if it's a 3/4" bolt the head should be an 1-1/8" or close. I've got a 3/4" impact so maybe it won't be too bad to get it loose.
Hydraulic rod bolts/ nuts are torqued pretty high plus loctite. Maybe starting at 2 or 3 hundred. Our excavator hoe cylinder was 800. Made a special wrench for it. May need heat.
