Greetings to all,, I heard a loud noise from underneath the boom and suddenly my boom doesn't lift. When I try engage it using the joystick, I feel no pressure. My cylinders are all good, no leaks but I see a leak from one of the values underneath the machine. Please help me. Thanks!
Welcome to HEF, Tactical Opossum ! Interesting username that you have. You need to go underneath and take a look, and maybe post a photo of the leak. There isn't much of a chance any of us can help you with so little information. I would guess you have a hose with a hole in it tho.
Sure, it's late over here. Will do just that at the break of dawn. Thanks
Break of dawn How very tactical of you, nocturnal one.
Hmmm.....ill take "piston came off the boom cylinder rod for $600.00 Alex!"
loud pop? I was leaning at " pin snapped and bound up some shizzle"
Either piston came off or by-pass valve in piston came out either way sounds like time to pull rod out of boom cylinder.
Thanks Vetech63, the mechanic is going take a look at it tomorrow and let me know the wrong.
Loud bang sounds like the piston bolt or threaded end of the rod broke. I had it happen on the stick cylinder on my backhoe. In my case I think the bolt was a little loose.
Thanks to all that contributed towards my post. I finally took the boom cylinder out and saw that the piston bolt got broken. I'm in search of a boom cylinder.
The part number should be on the gland so you can search online to find one cheap.
You shouldn't need a new cylinder or a new rod. If it uses a bolt drill and tap the rod for the next size up bolt and drill the piston to fit. There may be a seal that needs to be bigger for the larger bolt.
It's a bolt you should be able to extract and instal a new one. The tork for that bould is 1200#.
If just the bolt broke you can replace it. I forgot in my case the bolt ripped out some threads in the rod and that is why I had to go to a larger bolt.
Alex says" You must answer in the form of a question" What is the piston came off the boom cylinder rod. LOL
LOL............dammit, I knew that too!
