Loader Mahindra 26XL loader bucket floppy

jgeddes · Mar 11, 2017

I was trying to move a very large stump today with my Mahindra 26XL. Just as I was rolling it up, the stump came back down in my loader bucket and I heard a "pop" sound. Nothing looks broken and the loader arms move up and down. The problem is my bucket doesn't tilt, it just flops there. I can tilt the bucket by hand, but it always goes tilts (pivots) back down on its own weight. Any ideas? Thanks!

Sounds like either a seal in one of the bucket rams blew or an end came off a ram.

Yep sounds like a Cylinder failure. Because of how most FELs are plumbed one ram failure could/would cause both to "act" bad. Their are a lot of cylinder rebuild shops and if your FEL manual is like mine it has the cylinder brand listed. You should be able to just remove the ram and avoid having to bring the whole tractor in for service.

Where you using the loader as a battering ram when this happened?

I have a set of almost new Cylinders from a ML205 max 28XL Loader. The Pin eyes are 25mm bore, not 3/4 diameter like the MAX26 XL curved boom Loader. The pistons, seals and gland are the same.

To get your tractor back together quick, and easy, you may want to consider using my old cylinders to fix your current cylinders.

A spanner wrench tool, even a pipe wrench can be used to take them apart. It is easy to fix fix them yourself.

Then I suggest spending $350 buy a set of bucket cylinders from the 1526. Install those when you can afford the time to take the tractor out of service.
See my post http://www.tractorbynet.com/forums/...loader-curl-possible-solution.html?highlight=
Have a cylinder shop cut off the pin eyes and tube ends of your damaged cylinders ans have the weld them to the 1526 cylinders.
That should not be more than a few hundred dollars work. You want a competent shop to do it to get them lined up correctly and not cook the seals when welding.
You need to have the cylinder shop also add a stroke limiter similar to what is shown my thread. The 3/4" long limiter even could be made from washers just notched around the OD with a Hack saw.
The bigger bucket cylinders made the whole loader perform much more balanced. The loader lift cylinders on the Max are plenty for the tractors size and weight The loaders bucket cylinders just need more breakout force to match it's lift capacity.

You then can move even bigger stumps. PM me if interested.

Thanks for the quick replies! At the time, I was trying to roll over the stump, not really batter ram it. Still probably not a good idea. Especially with a big winter storm approaching Tuesday and no bucket movement. No snow all year and now it comes.

I'll stop by my mechanics shop tomorrow to pass on the information. Not sure I need the stronger loader right now, but I'll see.

Thanks again!

Check the quick-disconnect fittings up at the joystick. Mine started flopping and I thought for sure I blew out the cylinders. Turned out one of the hoses just came barely unclicked, wasn't noticeable until I really looked. Pushed it back in and it was fine.

I tried checking the quick connects, but it didn't help. There was a little fluid at the bottom of both bucket cylinders. I then noticed hydraulic fluid leaking from the bottom of one of the cylinders when I tried the joystick. Not sure if it's only one bad cylinder or both? I believe they're both attached to the same hydraulic lines, so the one closer to the joystick (on the right) has the leak.

I took the hydraulic cylinders off and the one definitely broke at the top of the rod in the cylinder. The other looks to be fine. I've contacted my dealer and they want almost $500 for a new cylinder (part # 1600C-9000 - description: 35X25XST425X650L (whatever that means?). I've been looking online and there's quite a few different hydraulic cylinder suppliers, but I can't seem to find anything that matches my cylinders. My cylinder information is as follows:

Retracted: 25.5" center-to-center
Extended: 42.5" center-to-center
1" rod
1" pin
2-1/2" pin width at lower pin
1-3/4" pin width at upper pin
1-3/4" outside diameter is casing
There are no grease fittings at the cylinder pin holes, just the at the pins themselves

Any ideas would be greatly appreciated! Thanks, Jeff

Read through the info from Mike above. He has done a tremendous amount of research including spread sheets and the like that can be found in his posts.

Your not going to find that cylinder from a manfacturer of standard cylinders.

I bought both 1526 bucket cylinders that have 40 mm bores with a 453 mm stroke, (644mm retracted /1097mm extended pin center to pin center). These new nearly identical length bucket cylinders replaced the OEM ML205 loader bucket cylinders.
The 1526 bucket cylinders are Mahindra PN is KMW31502148 for $380. As I upgraded the Max 28 Bucket cylinders, they are now just sitting on a shelf in my lean to. PM me if you want these original Max 28/max26 OEM 35mm bore clyinders, 80 hours on them.

The first 4 photo's are of the Max cylinders I just photo'd.
See the last photo of original Max cylinder vs. 1526 Clyinder or the right. It does not look much bigger, but 40mm is a lot bigger than 35 mm.
