CK30- Kioti loader failure

[TractorLegend]

I can't see where your tow chains are attached exactly but my guess would be that possibly a tooth bar adds some stresses not calculated in by the factory. The access door creates a weak spot where the tube has been cut open and covered over with a plate to make room to fish the hoses through.
I don't have my rig in front of me but I suspect a good look would reveal some areas where maybe some additional metal/ angle iron could be laid on there and welded to strengthen the area, if it doesnt impede movement of bucket, etc.
I wouldn't have a problem opting to do that as a "beef up" since we all add stuff like hooks, tooth bars and non factory mods and towing tie down so why not add some non factory strengthening in the areas needed?
And of course use that chevy orange to make it all look factory.

No its not Ansung... I can't think of who the Mfg is...

Only some of the loader models are made in Korea, some models are made here in Kansas by KMW.

Highbeam, I have 75 hrs on my ck30 with the 130 loader. Almost all of that time is FEL work. I went and checked mine and did not see a any cracks on it so far.

I can see when they routed the hydraulic lines through the assembly (which I presume was for crushing protection) it created some weak points, two large holes and the rectangular access panel, that would allow for twisting motion under load. The tooth bar may be a little too much for this configuration without frame modification.

I do see an opportunity to strengthen this configuration by removing the lines from within the assembly and welding it up solid. Then routing the hydraulic fluid across the loader by way of steel pipes. Good Luck, and please keep us informed. /forums/images/graemlins/smirk.gif

The company to which you refer is Taesung Mfg., but I'm not sure they do the KL130. I seem to recall that Kioti was trying to get away from using KMW. A lot of the earlier KMW stuff had bad tolerances when it came to installing, there was a lot of grinding needed to get the holes to line up, but the loaders seemed to be pretty good.

So many changes have come about since I first bought my Kioti, and I can't remember a lot either!

I wonder if keeping those cover bolts tight would help?

[Highbeam]

I never opened the cover. I am too swamped now to get it taken care of. Since I have the one year warranty the pressure isn't really too high. I can call the dealer and chat about it.

Jerry:

I might add that being in the steel business myself, I'd give an educated guess that the center section starts out as a leveled sheet of steel, by leveled, I mean that the steel starts out in a coil of what we call steel bands, most likely hot rolled. It's then run on an uncoiler and through a leveler and then is most likely fed into a press and is die stamped as a flat part. After that, it is most likely cold roll formed into the desired shape. If, the stamping die is worn, it could cause an edge fracture at the stamped edge which would weaken the metal and ultimately cause it to crack under stress (where the acess door is blanked out). That would explain why some loaders crack and others don't. If the Rockwell is too high it will also compound the problem.

 

[Kiohio]

Could it be drilled to stop the crack, then welded?

KO

 

[Highbeam]

If out of warranty, that's what I would do or have done. Also, using the block off plate for a template a guy could cut out a reinforcing ring to be welded around the access door opening to add strength.

What's to say the new loader frame is any better? Luck I suppose.

 

[Highbeam]

Update. I dropped the loader off this morning. The dealer will have it welded and reinforced. This repair would fall under but not extend my Kioti one year warranty. If Kioti tells him not to do it then it will be a new loader. The toothbar is on the bucket and he told me that even if the toothbar "caused" it that it is fine since Kioti authorizes the use of a toothbar.

It is very strange to drive around without a loader.

 

[IH3444]

best thing for it, just weld the cracks, and reinforce. I consider that just loader fatigue, and not a failure. When I was extremely serious about the DK45S I found the manufacturer website and copied the loader specs. Here they are, a bit jumbled....but readable.

Did you try calling Mr.Gye-hee Yu at the factory? I'll bet the language barrier would present some amusing situations.

I wouldn't be happy with a "weld job" on an in-warrenty tractor. Sorry but I think a replacement is in order here.

Turbo:

Let me relate a little story to you......

A week ago, an owner operator came into our shop with a leaking front drive axle housing. It had a pin hole in the casting in the carrier or "snorkel" that carries the output shaft and couples the front drive axle with the rear drive axle. The tractor is less than 6 months old and no, he didn't buy it from us, but we don't discriminate between our customers and non purchasing customers, service is service, warranty or not. Anyway, this guy is irate, he's leaking 85-140 all over and wants a new differential. Well, it's a warranty issue so, we call Arvin/Meritor who incidentally has bought Rockwell and they request pictures of the defect. We comply. A/M decides at that point that the rear housing can be fixed by cutting off the old "snorkel" and welding on a new one. Joe customer is hot, real hot. He paying a note of 90K and he wants a new rear end and he wants downtime. A/M don't care and won't pay downtime anyway. Their recommended fix is the replacement of the snorkel, period. Bottom line is, Joe customer can have a new snorkel, no additional warranty and no downtime. That is a decision that A/M mandates.

Same thing applies to Highbeam and his loader. If Kioti deems the loader repairable, they will instruct their representative (dealer) to affect a repair. If they deem it unrepairable, Highbeam gets a new loader. Either way, no warranty extension. Fair or unfair, that's the way OEM's handle their warranty claims.

For one, I don't like it and I don't think it's right,. but, that's the way it's handled industry wide.

Another thing to keep in mind is that on any warranty claim, at least in our shop and I presume most others too, The mechanical work performed is all based on a flat rate manual, that is, what Kioti (in the Highbeams case) deems reasonable to take apart and reassemble and mount the loader and in most cases, the flat rate leaves the dealership short changed, in other words, they make no money on warranty work and in order to stay afloat, the dealership has to turn a profit.

By the way, it's warranty not warrenty.

 

[Highbeam]

I dropped off a 125 hour loader with cracks and I will receive a 125 hour loader without cracks. For me to demand a zero hour loader without cracks is too much. I will have the balance of my one year warranty to watch for new cracks to develop and at the sign of crack #1 that loader is going back to the dealer. If that happens, I suspect the repair strategy will be abandoned for replacement. Even at that point, do I deserve a brand new loader or a good used one?

I am confident that in the end, I will have a crackless loader.

I am also confident that there are people that know how to properly repair and reinforce the cracked area to be better than new. I can only hope my dealer is able to source out a capable welder so that I don't have new cracks. After all, the new Kioti loader has welds on it in various places.

Daryl, a manufacturer has a duty to fix the defect and the resulting damage, for example if your fender falls off your vehicle because of defective bolts they have to replace the bolts and repaint the fender if necessary, they can argue that the fender’s purpose is to hold the head light and therefore simply bolting or welding the fender back in place is acceptable but we all know that is not acceptable because the scratched or damaged fender would greatly affect the resale value as compared to a vehicle whose fender did not fall off. Attempting to repair a defectively designed loader by simply welding the cracks may or may not be an acceptable fix, if the design is still defective or the resale value is greatly affected then you can demand a different fix. A person may have to go to court to enforce this but it can be done, we had a Chevy once that blew a head gasket at 5,000 miles and had to sue to get a new engine instead of simply rebuilding the old one, but I did and won because the resale value was greatly affected by their suggested “repair”.
The manufacturer will attempt to fix it the way they want but you may have more rights then those that are specifically spelled out in your warrantee. In the case of the differential A/M may have previously done the engineering to determine the fix was as good as new from a performance and resale value and therefore was willing to defend it in court if necessary. My opinion is that I doubt the service life will ever be as good as original with a field fix like you describe I think the owner may have been “harmed” by the fix.
By the way, next time I will try to remember my spell check /forums/images/graemlins/smirk.gif no wait, no I won't. /forums/images/graemlins/wink.gif
