Backhoe KB2475 Hydraulics getting very hot.

[Streetglide09]

Ok I'm a newbie, I've been looking in the Hydraulics Forum and haven't been able to find anything as of yet so here is my question I have a CK30HST with 12 hours on it and been using the backhoe mostly, It seems to work fine but after about an hour or so I start to smell odor of grease/hydraulic oil and the cylinders on the boom and dipper are very hot almost to the point of not being able to lay your hand on them for very long. I've checked the other cylinders and they seem to me to be normal warm but not hot. I've looked for leaks and checked the level of hyd oil and all seems to be normal. I called my local dealer where I bought the tractor and after the 3rd guy that I talked to said he has no clue and to just run it as long as the hoe doesn't hick-up. My thing is this I don't want to burn anything up.
The dealer said it shouldn't hurt anything and they would look at it when I bring it in for the free 50hr. service. I just wish they weren't so far away (50 miles)
If anyone has any suggestions I would greatly appreciate it.
Harley.

Welcome to TBN.
What year is your CK-30? Manufacture date, not sale date?
What is the routing of your hydraulic lines to your rear remote connectors to the backhoe? Does one line from the hoe go to the hydraulic fill port at the back of the tractor or do both lines go directly to a rear remote, (QD stacked females?).
I can't recall if the CK series has the ability to run the return line to the hydro pump's fill port, but if it does I'd start there with the kit that comes with the hoe, that unfortunately a lot of dealers don't seem to install. Others here with CK series can verify this option for you. It shouldn't be any cost to you since the tractor/hoe are brand new. Post back results.
Who's your dealer?

I recently purchased a DK40 and had them install the kit for the return line to go straight to the fill port. I was shocked to find that the dealer had no clue about it and even more shocked to find that one of the technicians in his shop actually tried to talk me out of it. I even decided to call around and ask a few other shops about the kit and was amazed that other shops didn't install the kit as well.
I would look threw the owners book to see if its an option then call the dealer and ask why it wasn't installed and why you were not informed of the kit or why you were not given the parts to install it yourself if desired!

My dealer's mechanic asked me if I was going to leave the backhoe on, or mostly use other 3pt attachments. He suggested that the kit would be better if the backhoe were heavily utilized, but not installing the kit was better if the backhoe were not used often but other hydraulic attachments would be used. Not sure why he thinks that, I haven't looked at it enough.

But he did admit the hydraulics will run cooler with the kit installed.

Install the kit, it is very easy to take off the fitting to use the fill port.

 

[davrow]

Murph, I have to admit it is only because of this forum that I knew the issue existed! I made sure they gave me the kit since I've read it is a pretty easy install. I won't be using the backhoe heavily for a few months, so plenty of time to get that done. Having their mechanic install the kit would have delayed the delivery and I just couldn't stand it!

Take a before and after pic to help you out.

I may be slow, but I'm learning. I have to do that or no one here on TBN will believe I did it! :laughing:

Seems the kit is available for your CK series tractor. Have your dealer install it at the 50 hour service. This should solve the overheating, and cost you $0 since it comes with the backhoe and should have been installed to begin with. Post back results.

Yes, I didn't mean to hijack the thread. I agree with this.

Coyote, I took the tractor back to the dealer last week and they did the return kit and it did cut back on the extreme heat and it seams to have more gusto in the hoe.
The year code is M so I guess from what I've read it is a 2013.

Anyone have the part number for this kit??? Mine's a 2010 CK30 gear.

COOL! Pun intended!:dance1:
I can't for the life of me figure out why some dealers don't put the kit on- especially since they come with the how from the factory?!

Get your dealer to get the kit for your hoe, have them look it up, and give it to you. You can install it yourself.

My dealer tells me they don't get these parts with their backhoes, and simply plumb them to the return port through the valve. I need the parts for this kit in order to hook up a hydraulic down force kit on my post hole digger, which has a single-acting cylinder with a relief valve that returns the oil through a second hose directly to the hydraulic tank. So I can't use the return port of the valve, and can't simply hook up one hose either. My dealer is ordering all the individual parts which make up the kit for me, since there is apparently no alternative. The price seems pretty reasonable to me, less than $75 including freight.

 

[Coyote machine]

Ok, news to me about them not coming with the hoes. Which hoe do you have? How come you need a down force kit for your PHD? I thought those were/are very rarely used/needed?

BS, they come with the Hoe, my dealer said he had stacks of them, "Always wondered why they keep sending these with the backhoes":duh:

It is on page 13-4 and 13-5 of the KB 2485 Backhoe Owners Manual.

I think your dealer is full of it!! After talking to several dealers about it they have all stated that they simply don't install the kit with the backhoe but it does come with every backhoe they get. I would call Kioti and ask them if the kit comes with the backhoe! Just last month when My backhoe arrived at the dealer guess what was included with it? I doubt they stopped including them before mine and then started including them just after mine.

Thanks for confirming what I thought to be the case guys.:thumbsup: Seems the OP's dealer is blowing smoke up a dark cavity, and, worse of all, charging him too!:confused2:

 

[Hard Knocks]

They come with the KB2475 and KB2485 but not the KB2465. It is not needed on the KB2465 as it doesn't push enough fluid to get restricted.

The return kit is essential to proper operation of the Backhoe. Without it the performance is slow and the fluid gets hot.

 

[paulfun9]

Well he has a DK45 listed as his tractor. That means he takes the same backhoe as mine does and that means his dealer is blowing smoke up his---! And trying to charge him for it. I would call him out on it and then after forcing them to hand over the parts he has already paid for FIND A NEW DEALERSHIP to do business with.

Anyone who would try to rip you off on the little stuff will do it with everything and soon start taking you with the big stuff as well! I have zero tolerance for bad ethics!
