Bent Hydraulic Cylinders - Now what?

[Wis Bang]

I have had them fixed @ a hydraulic shop. Took then the whole cylinder & they came back straight and w/ new packing, etc. wasn't all that much pricewise & was finished overnight.

Back dragging should be done w/ the heel of the bucket, not the leading edge.

...Use your dump on the fel (extend the cylinder) and go slightly past straight when bending it back and check it. If not straight enough, do it again with a little more bend at the wedge...

One thing I've learned doing stuff like this is start out at low engine RPM's. Slow and steady is key to this type of procedure working.

I have to say I am one happy guy tonight! Sitting back drinking my reward for a job well done.

pics 1 and 2 are before shots. Bend was pretty good.
Pics 3 and 4 are after shots.
Pics 5 and 6 are of the leather I used and the pipe. The brown spots are not rust, thats leather on the pipe! Lots of pressure in there.

I could not believe the results! I was truly amazed. Even though in one of the pictures it looks like there is a small gap under the board, there really is not. Maybe I was asking too much of my three year old assistant The board is extremely flat as I put it on the jointer before using it as a gauge (mild woodworker; mostly precision cut firewood .

Thanks a ton guys. Really did save the day!

Now, I can show you guys what I really needed it for. My latest project?

Would love to hear your input!

Thank again,

That is sweet, have to remember that one in case it ever happens to me, was it like bending something springy where you have to go a little past what is straight so it doesn't just spring back?

Is that your work on that web site design, if so I'm more impressed with your techno graphic abilities.

Indeed a creative and unique solution... That's why I love hanging around smart fellers ... mebbe some of it will rub off on me.. lol

Good job! Remember retract the bucket and backdrag w/ the heel of the bucket. The cylinder is at it's strongest when fully retracted. The front edge of the bucket should only point down to MT out the contents.

This is just utterly ridiculous. Why can’t manufacturers get the basic designs into production? How hard would it (rhetorical) be to include a relief valve so the cylinder is never exposed to rod forces great enough to pass the point of buckling? Maybe an aftermarket relief needs to be installed to prevent this from happening. Dragging with the rear edge is just a mitigating action, the front edge should be able to take it.

Ohh, I neverrrrr backdrag with the edge..

(going to **** for lieing..)

I think No make that I know it should be mandatory when a person joins this board he needs to look at some of these masters 3RRR for one and some of the Hydralic Gurus like Kennyd and wayne the hose guy, I think I learned more here in a month then I did in 2 yrs of trade school

glad that reverse bend worked out for you Doug
like the log home rental thing

I grew up watching my dad operate heavy equipment. Any experienced loader operator would float the bucket flat, tip up the edge [get the teeth out of the way] and backdrag w/ down pressure.

Union operators that did not bust up stuff needlessly were the first ones requested out of the hall each spring AND the last to get laid off in the fall...-or- were the only ones working those elusive winter time jobs.

Now take a CUT or SCUT and build a working FEL that isn't too heavy & things will be easier to bend and break.

A 977 CAT could backdrag w/ the teeth pointing down but the massive hydraulics would weigh more than these little tractors!

When Dad retired to my great uncles home, he had a fellow operator bring his smaller cat down [for a set of teeth] to move the gravel uncle had laid across the lawn to get to the carport built on the garage that never progressed from the workshop he used to build the place. Dad wanted the gravel in the road and was adding garage doors after removing the uggly car port. In a fee hours the guy was able to rake the gravel up and restore the corner of the lawn & spread the gravel where it should have been.

He didn't need to pull the teeth and dad just raked the dirt & scattered seed...that's why they are called operators.
