LX3310 Exhaust Smell

[zdriver4]

My LX3310 had the awful exhaust smell described here, until the first regen. It's still there from time to time (18 hours currently) but no where near as bad as when I first got it - the smell stuck to whatever I was wearing if I was working outside the cab (chipping branches) during the first few hours.

My advice would be plan some heavy work to get it nice and hot a few times, that should speed up the process. Expect it to get smoky the first time you work it hard, then other than a bit during the first regen, it hasn't smoked since.


This is otherwise not at all typical of DPF Kubotas - my L6060 exhaust has virtually zero smell once warmed up, to the point of being able to use it inside and not being able to smell it. Hopefully the LX3310 ends up the same.

Update on mine: First 6 hours - as mentioned earlier - had acrid smell immediately upon start up and it was persistent. At 6.5 hours I happened to get grill covers from a guy on OTT. Put those on and ran it hard for an hour (snow removal via mid-PTO), got so hot that the EM light went on and I had to take off the covers to cool it down. The smell was there at the start, but was gone about the time the EM light popped. Ran it 3 more hours on and off over the next few days with varying temp/exertion levels and had no unexpected smells at all - it is apparently fixed. Anecdotally seems like there is something that is being generated by the engine/emission system that stops after the engine has been worked hot/hard - and for some the first regen serves that purpose.

Re: LX3310 Exhaust Smell, Eyes and Sinus Burn

Another smelly lx3310, only 3 hours, but man it will choke you and burn your eyes, and it will stink up a garage in a hurry, and it doesn’t just air out with doors open, . We aren’t getting much snow so hard to get it hot.

^^ OP here, yea, my issue started different than any diesel-powered equipment I've worked in my 65 years, this was completely different. Acrid-eye-watering smell the instant I started a cold engine. After my first re-gen at ~18 hours and the few hours after, relatively little objectionable smell sense. I initially questioned whether Kubota added a fuel additive (for the right reasons) into the tank for initial break-in, causing the smell. IDK..... Carry on, thanks

Re: LX3310 Exhaust Smell, Eyes and Sinus Burn

That smell is from the engine not being hot enough. Teir 4 is meant to be work hard and hot my l3901 does the same thing until it is hot but i use it for at least and hour of work every time i use the machine. 48 hours and no regen yet

Just a follow up on exhaust smell at 75 hrs on my lx 3310, Ive had 3 regens, all while operating, smell, not bad, but overall, if your out and around it while its normaly running it’s pretty strong. Other than that runs great, starts much quicker than my B3350 did. love it.
