Kubota B3350 tractor regeneration problems

[JimR]

Unfamiliar with the Kioti system but one of the things that Kubota did to my 3350 before authorizing removal/repair of the cylinder head, etc., was to send out the injectors and injection pump to verify that all was within spec. It was.

The Kioti can have the injectors tested on the machine. Not sure about the Inj.pump. The Kioti has a DPF exhaust and sensors in the DPF and under the turbo. They also have a differential sensor on the DPF which shows the exhaust balance from the front and rear of the DPF. This is what calls for a regen when the balance is off.

This is the most basic, simplest, and most reliable method to redetermine regen. Why oh why would Kubota do the crazy method they try to do that is failure-prone, unreliable and probably more costly? Do they not realize that they have now permanently ruined the reputation of a very solid mechanically injected engine? I find it crazy stupid that they don't just sell a retrofit kit to convert the 3350's that are clearly a design defect to this and take their lumps. ****, I would buy one to avoid the crap I deal with now.

That would be too easy and they would have to admit to a lot of people that they screwed up. As with the Kioti that I own. I wonder if the early injectors and early injection pump may be the cause for my problems. Why did they upgrade all the NX series tractors 2 years later to a different injector and a different injection pump. I asked Kioti for all the service bulletins for my tractor. I have not gotten a response from them. My thought is that failure to reply means that you are hiding something from the customer.

Can't speak regarding Kioti, but Kubota has thrown in the towel on mechanically injected Tier IV engines and redesigned the only one so designed and sold in the US.

The new common rail injected LX3310 replacement for the B3350 has been announced and will be showing up on dealer's lots within weeks.

So they redesign a tractor with a new model because the old model doesn't work right. That does not solve the problem with all the older series tractors that are bound to eventually screw up and have to be dealt with by the customers. I see a class action lawsuit coming for Kubota. The least that they could have done is retro fitted the 3350 with the new system and alleviated the problem. Kioti has a new system already too for the NX series. Weill it be the final Teir IV? , not sure. They call it the CRDI diesel with Daedong ECO Technology.

Do not expect a class action law suit in this case.

Not enough potential for attorneys.

I went through the DPF and sensors replacing drill last year on my 2013 3350 at about 880 hours. Cost right around $6K which adds about $5 in operating costs per hour. What a rip-off. Speaking of rip-offs, a friend of a friend is wondering if the various DPF emulators are that? Of course this would be used on a tractor that is not operated in the USA. I was just curious, mind you, but can't find a single review online. Think these are made in Turkey:Emulator

Kubota recently extended the warranty on the B3350 reformer and related components (with provisions) for the life of the machine. Do not know Kubota's policy regarding those who have already paid for emissions system repairs but it would certainly be worth inquiring in order to find out.

Thank you! I'll check with my dealer again. Before I had the work done, I asked about any extension - they checked and got back to me with a "NO". Can you point me to a Kubota source on the extension? They still may deny a refund, but a definitive source would surely help.

There is another thread here that specifies the exact bulletin by number. I verified the bulletin number and its contents a while back, the info posted is correct. I'll look for it and if I find it I'll come back here and link it.
