Kioti ck3510 loader issue

[justman777]

Um... That's definitely not "normal" for any machine, new or otherwise. I think I'd take it to the dealer and either have it fixed or get your $$$ back.

Also, I wouldn't waste your time on the Kioti Customer Care. Those quacks don't know the first thing about machinery. I suspect they were working in McDonald's the day before they started working there, and they're just reading off a database of canned responses. Your best bet is to work through your dealer and have them contact the regional dealer assistance line with a description of your problem. How they respond would dictate any future response.

I have the same issue with my ck3510se loader. I spoke with Tmod on facebook, and my dealer actually got me the same valve he used, and it seems to have corrected the problem. I had my reservations initially, as this seems like a workaround, and not an actual fix...but it does seem to be functioning correctly now, with the flow control valve.

I also have the "normal" jumpy 3pt hitch. Generally this isn't much of a problem, although it does make working with a box blade somewhat difficult.

Overall, I'm still very happy with this tractor...just wish the support for these issues was a little better.

Thanks for posting this issue. I have only had one other tractor and could not put my finger on what was happening. This definitely occuring on my 2019 CK2610HST. I have asked my dealer to respond with Kiotis position on the matter and will post his response.

Maybe I missed it in the earlier posts, but it seems strange that this problem does not affect every unit. Perhaps it depends on the included options? Anyway will post back when dealer responds. Toukow

Tmod the link you posted for the fix in an earlier post no longer works. Do you have a new link with the fix. Thanks

If I have my bucket at a specific downward angle, then attempt to back drag, it will flatten out when it makes contact with the ground. I have to lower the loader arm then press the bucket down to the angle I want it to hold at.

At that point it値l hold the angle. Also, it never bleeds of while curling or lifting something, so I guess that痴 good. I値l post a video of what I知 referring to.

Another gripe of mine, hydraulically speaking, is the factory Kioti backhoe struggles to curl, lift and turn simultaneously. Kind of frustrating. Again, I値l post a link to a video. Perhaps I値l start a fresh thread about these very things in case the FEL issue isn稚 what y誕ll are describing.

I am also interested. My 2020 ck3510 has this problem. I have about 28 hours on it and I swear it didn't start until around 20 hours.

Looks like Tmod took that page on his website down. I wonder if Kioti corporate got after him.

Anyway I have a new-to-me 2019 ck3510se that has this problem, so I'd like to know the part number and see a pic of where to install such a valve. Would probably opt to try it myself instead of have to yell at a local dealer for warranty coverage, since I bought it used from the other side of the state.

Hopefully he can just rename it to kioti_info.dyndns.org to avoid issues with the Kioti domain name.

So is there a fix to this problem? 3 pages of the issue and no fix (backyard mechanic or dealer)? I have the same issue with the backdrag on my 2019 ck3510. Sure would be great if we could get the right answer and fix the problem.

It is air in the system that causes this problem. Cycle the curl cylinders a few times but control the dump speed. If it dumps too fast, the pump can't fill the cylinders fast enough.

One technique that works is lower the bucket down to the ground fully curled then dump to the angle you want. Having the resistance of the ground against the bucket helps.

Another thing some people have used is a flow reducing valve on the return line. This will slow the fluid exiting enough for the pump to keep up.

Hope this helps.

Yeah all that sounds like a good summary, K5. But what i need is some info on what kind of valve to buy and where to install it. Anyone have links and pics they could share?

 

[K5lwq]

It is called a Hydraulic Flow Control Valve. You would put it in line between the loader valve and the rod end of the cylinder.

There used to be a write-up, but I can't seem to find it. For my KL4030 loader on my CK3510, here's what I bought:

3/8 NPT 8 GPM Prince WFC-600 In-Line Flow Control
3/8" NPT Male x 3/8" NPT Male Straight 5404-06-06 Adapter

And here's how they're installed:

Unscrew the male quick disconnect from the brass-colored NPT-to-flare adapter on the white line (the line for the rod-end of curl cylinder). Install the flow control valve and NPT adapter between the QD and the brass-colored adapter. Open the flow control valve just enough so that, when dumping the bucket, the hydraulics have to "work" to do so.

Thank you Stan B. After two years on this thread and so many requests, it is great to finally have solid information & part numbers.

My friend has a CK3510 and that droopy loader bucket drives me crazy when we work together. It's his first tractor, he loves it, and he thinks that all loaders work that way. He doesn't mind, but that droop always takes me by surprise and scares me.

Finally, a fix.
thanks,

Yes! Thank you Stan. I hoped it was this simple. $30 and an hour to quickly fix a problem that people spend a lifetime hating, or dealerships hours of “diagnosing” and throwing parts at.
No loader bucket should be floppy! Don’t tolerate it, folks.

 

[mcmopar]

Thank you Stan B, I just ordered the parts and thanks for the installation pics and instructions! HOPEFULLY no more floppy bucket...

You can also just use a Flow Restrictor fitting on the rod end of the cylinder. Takes up less room and looks a little cleaner, The flow restrictor will balance the flow between the High and Low volume sides of the bucket cylinders. Balancing the flow eliminates the "floppy" bucket.

Hope this helps

Glad to help. Let us know how it works for you. One additional benefit that I noticed is when I'm lifting something very heavy with my pallet forks, it used to dump a just bit when I'd move to the curl. Like there is a dead spot in the spool where it is neither sending pressure, nor being closed off. (If that makes sense.) That no longer happens with the flow control valve in place.

I think they just use low budget joystick valves on these tractors.

Would you have a picture/link to said fitting? I tried googling, but when you don't know what you're looking for exactly, anything could be right/wrong. That would be appreciated.

My dealer actually rebuilt my cylinders because of the issue. Would like to see it didn't return.. And if this is a clean and simple install. Bingo. Thanks.

 

[K5lwq]

The problem with a flow restrictor is it will restrict in both directions. The adjustable type normally will allow full flow one way and reduced flow the other. Also using The adjustable one allows you to fine tune the flow to maximize dump speed vs pulling air. But here is a picture of the fixed type.
