Kubota L4400 Bent Front End Loader Dump Cylinder UHOH

[dex3361]

The only thing I'd worry about changing rod dia from 30mm to 1.250 would be the one cyl will be carrying more load (6.5%) when retracting (holding bucket full of material)......would this stress the FEL frame..??....Maybe/Maybe not..??

If a rod dia is changed then you'd be wise to do both...

If I swap cylinders I will swap both at the same time. I think it would be a bad Idea to have to different cylinders. Thanks.

I took some pics of the cylinder. Opinions on whether it is repairable?

It would probabally cost you more than the OEM replacement.

And definatally a lot more than a pair of aftermarket cylinders

Forget it.....I just threw one out last week....same problem....same style...Took it apart to see if anything was usable....NOT..!!...

It needed everything but the piston head and the nut on the end of the rod...

Pulled it out of the scrap bin....30mm rod x 50mm bore

If you can find two aftermarket cylinders that work for you, I'd suggest putting the remaining good cylinder on E-bay and selling it to pay for the replacements.

If it's over $600 new, you should be able to get at least $200 for yours, which will most likely pay for most, if not all the cost for your new cylinders. Use the new ones for a bit first, just in case you DO need to get an OEM replacement for some reason.

The L4400 is common enough there should be some demand for that part.

If I needed a replacement cylinder, I'd pay $200 for a good used one, but $600 is too much.

Typical Kubota, the stuff is good quality but expensive to the end user.

Your cylinder looks a lot like the one I mounted on my rear blade, after it was overextended and bent, that is..

Great suggestions. I will probably do just that. I searched ebay and found a couple of kubota cylinders but none of the one that I have.

Sheww, How much does it take to bend one of those?

 

[wdchyd]

Not very much when it's extended all the way out......30mm Dia....

I made the trip today to the Hydraulic shop and the shop manager told me he could fix the cylinder. It sounded great till I heard the cost $600. I told him I would buy a new one at that cost. It had a deformed place at the end where the gland broke. So the TBN brain trust is on the mark again. I have found a couple of close replacements. Not exact but close. The original cylinder is made by ROQUET in Spain and is a metric size cylinder that is
1.968" bore x 18.68" stroke 26 9/16" retracted (center line pin to pin) and 45 1/4" extended (center line pin to pin) with 1 " pins on both ends. The replacement is a little shorter and is a stock size Baileynet 2" x 18" here is the link. I will have to do some trimming on the cross tube on one end and put shims in the other end. Any thoughts or ideas? I am all ears. I am still debating on the exact cylinder to purchase as the one that
