Replacing O ring on loader

By the way, I keep a hose in the ports and the other end of the hose tied to a bucket to catch the fluid. Not perfect, but better than a hydraulic shower.

It only took me most of my life before I figured that one out. Bungeeing the hoses into a 2-1/2 gallon jug catches just about all the oil without any splash.

It's reassuring to hear that people clear on the other side of the planet do the same dumb stuff we do over here.

Well, there's dumb and then there's dumb. I manage the former (I hope!) Learning through experience is always the best form of learning. I get pre-learned stuff from TBN and I try to contribute back if I can! The point about keeping the cylinder pinned before you unscrew the cap is a case in point. I'd have been in trouble with the backhoe rams if I hadn't done it!

Now you can't get away with that. I bet that idea came after the first shower!

I picked up my o-ring package last week ($40.00 OUCH!!) but I can't live without my loader. I pulled the cylinder off ond noticed that the metal ring that screws on the end of the cylinder (and hold the o-ring in) was cracked.
I should have that part here Monday or Tuesday. I will let you know how things go when I have all the parts. THANKS for all the information!!

Actually, it came before the first shower. The first shower was from 100 psi air in the cylinder pushing out the rod. It came out, stopped with the strap, but the strap did little to slow down the fluid. Odd. I can still taste it...

EEEWWW! (I'm not sure that is the correct spelling Australian or American, but....) At least with me, all I ever got is oil over the overalls and oil in the boots!

Jddodge - $40 for 2 sets of seals? That's about what it cost me. I suspect the seals actually are a bit more spiffy than simple buna-N O-rings you get from the local hardware shop. At least, I hope so! The dust wiper seals on the cylinder ends seem to be particularly nice for the loader arm rams I have...

Cracking the end-cap is something I'd not expect to see (but since I'm not a hydraulics engineer, I'm prepared to be called wrong on that). The forces should resolve along the axis of the ram - cracking an end cap makes me think of serious axial loading - which shouldn't be the case on a loader. Anything weird happened to the loader ever?

I think that's the correct spelling. It taught me to keep my big mouth shut! At least I have glasses that kept the stuff out of my eyes.

The end caps often crack when you use a pipe wrench to take them off or a chisel to hammer them off. The correct tool isn't that expensive, but you have to have it in hand.
