Kioti Mechron Owners, Some Questions

[DrRick]

i have a mecron and two other friends also have them we have had no problems of any kind on ours. The cvt is the same type as almost every other one out there . I suspect the problem is that the 2 halves of the clutch sheaves are binding on the engine shaft and not allowing them to seperate easily. This happens on car clutches as well. Rust buildup is usually the reason. Any moly type grease would do the trick. .

I believe the CVT's for the Mechrons were built by Hoffco/Comet. There was a delay in the introduction of the Mechron back at the beginning because Hoffco/Comet went belly-up (around the end of 2008) and their CVT had been spec'd in by Kioti and suddenly they had no supplier. After a little while Certified Parts Corporation bought out the assets of Comet and resumed manufacture of the CVT's. I was all set to buy a Mechron at the time but the CVT supply situation scared me off. I'm not really sure of their present status. Here's a couple links to Hoffco/Comet's CVT's and the story of Certified Parts buying them.

I purchased my mechron in 2011. We drove virtually all other utvs before deciding on this one. I have not been so pleased with it. It is hard to change from drive to reverse or the other way around. I have had shoulder surgery and it really hurts my shoulder. We are now having problems with the CVT. The mechron started to continue to go when you applied the brake. This got scary as I almost hit a tree. My husband took the cvt pulley off and found several parts worn out. It only had 500 hrs on it. We have had a terrible time trying to get instructions on how to fix it. I contacted two different kioti dealers and neither even knew what I was talking about, so we have had to try to figure it out. I also contacted kioti customer service rep and she sent me instructions, but it was the same one that I had already purchased. The instructions that I have call for the cvt pulley to be greased, but doesn't say what with. I would love to talk to someone that has a clue what to do. I like the mechron but probably won't buy another as I have had this problem and no one knows how to fix it. I would have thought the dealers would be more knowledgeable.

I've owned a 2011 Mechron for about a year. When I got it it had the same problem where it would keep driving at idle, caused by the primary clutch not disengaging. This will also make it difficult to shift because it's loading the gears. I took the clutch apart and found one of the steel rollers had a flat spot worn on it. Kioti does not sell parts for the clutch, they only sell the whole assembly for about $1000. I have a lathe so I was able to make a new roller. Some other parts looked worn, but with some filing were usable. I lubed everything with dry moly lube before reassembly and it's been working great ever since. The service manual says to grease all moving parts of the clutch except for the belt and pulley surface, I'm going to grease it next time I have it in the shop. Mine doesn't make any squealing or clunking noise. One of the reasons I bought the Mechron is because the clutch worked so well on the one we test drove, and the brand new diesel Ranger we drove was jerky. The Mechron is not the only machine with these problems, you can find similar problems from any of the UTV that use CVT.

According to the service manual there were two different clutches used. A Commet type (Comet?) and a TGB type (Taiwan Golden Bee). They spell Commet with two M's, I assume it is a mistake and they mean Comet. The Commet type has four rollers (poor design), the TGB type has three rollers. My 2011 has the Commet type. I could not find any aftermarket or other OEM clutch of this design, though the Comet 108 4-Pro looks similar. In any case it mounts on what seems to be a standard taper, I don't think it would be very difficult to find an alternative that fits, or worst case make a new flange/shaft to mount the clutch of choice. One would need to decide if it's worth spending $1000 for a Kioti replacement or $400 plus possible machine work to fit a different clutch. If mine ever needs replacement I'll be looking at adapting something different.

If anyone needs the service manual for the Mechron it can be found for free in pdf format. It has a pretty good section on CVT troubleshooting and adjustment.

I don't know if that's true, that replacement parts can't be bought for the clutch.
But if it is, that's just lame. It would prevent me from ever buying a Mechron.
I have owned many belt driven snowmobiles and atv. And all have offered replacements parts for the clutch's.

It's true. You may be able to source clutch parts from Comet or TGB, but Kioti will only sell a complete clutch assembly. The best price I could find was just under $1k. It is a bit disappointing but it certainly wouldn't keep me from buying another Mechron. Lots of guys who bought diesel Rangers are finding out they have clutch problems that can't be fixed without spending $1500 on an aftermarket clutch. For 2015 they switched to a Kohler diesel engine/trans package and I'm hearing they are burning drive belts going up hills, and there is no fix yet.

My Mechron is not actually a Mechron. It's a Bad Boy Buggies XD. They are also sold as Cushman 1600XD. Three different names, all the same machine. Mine replaced a Polaris Ranger 500 because I was tired of hauling gas cans back and forth. It's pretty clear Daedong looked at a Ranger before designing their machine. The chassis and suspension is so similar there's no way it's a coincidence. Some parts appear to be exact copies of Polaris. Other parts like switchgear and engine come from their tractors. Aside from the hood being made of ABS instead of a more durable plastic, I think the quality is every bit as good as a Polaris. The steel vs plastic cargo box is really personal preference, they both have pros and cons. The instrument panel on the Kioti is a little nicer, and I like that the shifter goes from neutral to high instead of going through low first like a Ranger. I don't like the location of the park brake lever, a common complaint. The front axle has a clutch type limited slip diff, it doesn't work as well as the Hilliard roller sprague locker in the Polaris and Gator, but I can only tell the difference on extremely steep rocky trails or deep snow. Overall I've been satisfied with the Mechron, it drives so well since I fixed the clutch, but I do miss the power and speed of the Ranger sometimes.

I'm a bit off-topic, but after looking into utility side-by-sides, I'm now looking for a 2014 or newer Yamaha Viking.

Of importance to me is the ease to get in and out, to feel like I'm riding in, and not on the machine, locking diffs all the way around, the ability to get a full glass cab (supplied by Curtis), and gas engine so as to be able to run in a Minnesota winter.

Here is a biased comparison of the Viking to the Ranger.

Here is a biased comparison of the Viking to the Ranger.

Typical comparo vid, full of carefully chosen features and specs with some good acting mixed in, Polaris produces similar ones as do the others I'm sure. Most of the features they are touting as superior could just as well be used against them. The longer and wider wheelbase is an advantage in ride comfort, but a hindrance on trails in both breakover angles and squeezing between obstacles. I don't see any advantage to the low seating position for work/farm use, I want to sit up high so I can see when navigating through a gate or around a tree. I don't understand how it would be any easier to get in and out of that than a Ranger. Coming from Yamaha I would guess it's a better engineered machine than a Polaris. That CVT system operates the same as the aftermarket Duraclutch for the Ranger, it is probably the only real advantage I saw from watching that video. I personally don't have a problem with using brakes to slow a vehicle, but the transition from engine braking to freewheeling to braking can be a bit annoying.

Rebuild kits are available for the clutch you need part number U3210-29062 and I believe list price is right around $160.

 

[Interceptor]

That's interesting, have you ordered the kit? It's not listed in the parts manual and the number does not come up in any of the online Kioti catalogs. It must be a new part number. I did find it in a .pdf manual for the Cushman 1600XD.

I sold mine a while back, my wife never really liked it, mostly because it was just too slow. We got a Ranger Diesel. The Ranger is considerably faster and steers much easier, but the clutch sucks compared to the Mechron.
