Re: PDF cleaning service
There are quite a few places in this area that do it.
I have heard of Kubota dealers-and individuals-who have removed the DPF from the tractor, soaked it in a bucket full of simple green, then washed it out with a power washer. Not a good idea, for many reasons. First it wont' oxidize the soot that's stuck in the substrate. Second, if it's damaged during the DIY cleaning, you get to buy a new one. And with that comes with the headache of ordering it...as the EPA mandated that replacing a DPF requires some weird hoop-jumping garbage, typical of anything with government intervention. Overcomplicated for a simple task, but understand why. They (kubota) is required (by the EPA) to document replacement of the DPF. And thirdly...when it gets dirty, or is replaced, diagmaster has to be used to re-set the system. If it's not, it's quite likely that it'll either want to regen too often, or not at all. IF not at all, when the filter gets plugged, it's possible that the engine will melt itself down from the excessive heat, similar to stuffing a tater up it's exhaust pipe and it not burning out. It makes enough EGT to melt parts.
They're charging us about $250 to clean a L01 DPF locally. Only had to do 2 of them since the first Kubota DPF's showed up about 5 years ago and both of them were due to a rolled tractor, fill engine and exhaust with oil, and the system "thinks" that the DPF is "sooted up"...but it can't distinguish oil fouling from regular soot fouling. That's also why it's important to keep these things maintained properly.
