the kubotas ive seen that have shutdown due to high exhaust temps, could possibly be a safety issue due to the extremely high exhaust temps generated by a regen...

something else popped in my mind, what are you doing when it happens, are you running a hiflow attachment or?

:eek:
i have been running a high-flow attachment ... asphalt profiler , but my engine / hydraulic temps are not getting that hot
we are looking at getting some new sensors for the dpf this week and see if that changes anything

To me, issues like this are the biggest strike against all the aftertreatment nonsense.

Not the increased fuel burn, or the urea, or having to bake out the can every xx,000 hours.

But problems with shutdown where the computer does not tell you what its problem is, and the dealer can not figure it out. Why all the sectrets?

yea it sucks. even at the dealer level trying to get info is like pulling teeth sometimes. we've run into problems that the troubleshooters dont have an answer for. they rely heavily on the engine OEM engineers, and typically they aint talking.
it's taken well over a year for our OEM troubleshooters to be able to "decipher" the readings we capture, and have gotten much better about offering a solution just looking at the data stream we sent them. the hardest part for the dealer is being able to replicate the problem while they are monitoring the ECU. or us, most of the time we cant just throw parts at the newer engine and DEF systems, warranty wont pay for it unless we can provide a definitive cause

:eek:

I've either talked to or heard of many guys having this or similar problems with the Tier IV equipment, makes me glad I own older stuff, to be honest. I remember when "smog equipment" started happening in the 1970s, added on charcoal canisters, air pumps, etc. which did little good, robbed performance and added unneeded complexity to engines. I might be wrong about this, but the add-ons now remind me of that time, and I won't consider newer year model equipment until we have a quantum mutation in combustion and emissions control, eliminating all the hardware. To me, the only thing more frustrating that something that flat doesn't work, it something that only *kinda* works. I ran OshKosh S-series concrete mixers for many years, and on several occasions the Cummins emissions controls would take a dump and derate engines, occasionally shutting them down all together. I cannot begin to describe the horror that goes with having 10 yards of concrete on board, sometime with chemical accellerants added in winter, and hearing that engine die and that drum stop rolling. Simply because of an emissions signal that wasn't making sense to the ECU. The last time I had it happen, the truck was down for 3 weeks, we lost a $1300 load of concrete, and the repair bill was over $7500. I could turn probably 8 loads a day in that rig, at roughly $1000/load. Do the math on that fracas.

the dealer swapped out the dpf last week
the old one was 4.2kgs heavier then the new even though it had only just done a burn
what we did notice was a white stain down the exhaust from the ad-blue , maybe over-spraying or something
we have now swapped out the ad-blue injector to see if that makes a difference
modern tec sucks

is there anyway possible to just remove the dpf system?
no-one has worked out how to do it successfully on the tak's yet
see if the swap out of the dpf filter and the new ad-blue injector make any difference

wow! clearly the filter got sooted up. This engine is used in several different machines, Taki, CAT, and Kubota that I know of. I am curious if they all are having these issues or just Taki? I would think that the engine and its regen/DEF system would be identical regardless of what machine it is in. I don't see Kubota allowing the engine to be messed with by the individual OEM, but maybe they can alter some aspects of the engine. I have had a 272D on demo for a while and one of the issues that I have is that the Kubota engine has SCR and a DPF. I don't get the redundancy in that. The CASE SV340 and all of their SCR machines don't have a DPF filter at all. They apparently are able to meet emissions with just DEF fluid. It is surprising that Kubota cant pull that off.

once again the v2 has stopped ...
it was in auto burn , had just started to do the burn when i jumped out of the machine to swap attachments and then the machine stopped
we had an air blower on it to try to cool the dpf down for 35 mins with no success so we ended up having to put alot odf water over it to get it going
spoke to the dealer , he said to run it in manual burn mode , tried that , the machine noitifed me that it required a burn , stopped the machine as per procedure , activated the burn , at the time the dpf was 48% full , turn on the burn , it jumped to 125% full then dropped back to 48% and slowly done the burn , the burn dropped to 24% , it took 14min to complete
just so over this machine for the few small issuses that Takeuchi dont know how to fix

So since you posted this I came across a bunch of youtube videos on DPF cleaning.

It seems the git-r-dun rednecks these days are blasting them in reverse with a power washer (carefully). Something I remember someone saying they did on a Ford way back when they first came out.

Of course all the nay sayers say it will wreck the entire machine but the guys that are doing it say it works just fine and some manufacturers are switching to a wet process now too (Detroit diesel)

As for me, I don't think it will necessarily hurt if done carefully because the DPF gets wet enough anyway with condensing exhaust on a cold day.

YMMV, don't tell anyone you did it, etc. etc.

I believe an outfit in the states is comming up with a new ECU program that does away with the emissions crap. A bloke is taking his ASV RT 120 there next week. It will come back as a 145 hp machine so be patient Rockman, if it works and they get a program for the Tac your troubles may be over. :)

It might be shutting down due to low oil pressure or low coolant level
