MX5200 Engine Problem

[sixdogs]

Any idea what models this affects? I have an MX5100 and wonder if I'm in the mix.

The freezing is as in froozen water or iceing . And from what I was told today at my dealer the update to the venting system will only be addressed if the tractor has the isue like mine had and is a major deal. But all the new units that are being built will have the new update. I am glade they have a fix for the isue and my unit will have the update. But just me thinking , I would think it would save Kubota a lot of money if they would have a call back on all the tractors in cold weather areas fixed or updated.

Rabcon, are you sure that's what the Kubota dealer said? It doesn't make much sense for a company to act that way unless maybe they are still trying to figure it out themselves.

I also have a 2014 MX 5200 that did the same exact thing yesterday. Bought 9/2014 with 115 hrs on it. Got away from New Hollands because I thought the Kubota's were better...now my old New Holland is my loaner. The dealer acted like they had never heard of this problem before. kind of makes me wonder if it is a problem they are keeping quiet since it is a new model and motor.

Hi WBJ Jr, - thanks for your PM with the scary details on how your rig behaved as the engine went out. It would be good if you posted these details here too (maybe without naming dealers) so there is a clear public record of the TWO MX5200 occurrences, rabcon's and now yours. If the factory is deciding how deep to dive on the fix/recall they should know TBN members are reading and talking about it.

I had a issue the other day with my new L6060. It was a real cold day and I was blowing snow, I slowed the tractor down to idle for a minute. When I reved it up to start working again the exhaust starting smoking, huge power loss and error code 3001 was showing. I called my dealer and he knew right away that the EGR had froze up. He said when that happens the engine starts sucking oil from the crankcase past the piston rings and starts to burn it. The code has something to do with unburt fuel in the DPF.

It is still showing the error code but the red warning light has gone out. My dealer says the code should go after the first regen. There is an update kit but they are backordered. It sounds like it is some kind of heater.

Perhaps Kubota should speed up these update kits or they are going to have a lot of fairly new engines to replace if this cold weather sticks around.

"The perfect storm". This weather combined with Kubota's design problem. I bet Kubota hates this storm worse than those living through it.

Did the engine speed up? How long did it run? Did it slow down by itself or did you do something to stop it? Did turning the key (shutting off the diesel fuel) have any effect?

The engine did not speed up, it slowed down perhaps it went into limp mode? It only ran for a couple of minutes, just so I could get it back into the shop. I could shut it down using the key.

Yours must not have been totally feeding off of the engine oil.

RAZOR...I had a similar experience while blowing snow with my B2650...loss of power and lots of black smoke..In my case the air filter had sucked in a whole pile of snow from the blow back from the blower and the filter was completely coated with 1/4in of ice. I realize your tractor is a different model but any one experiencing power loss and smoke while snow blowing might want to check their air filter.

I did check the air filter and it was clear of snow and ice but I have heard of the air filter getting plugged with snow. Thanks for the tip.

What I posted is what I was told , And no I did only post only what I was told . Just trying to keep anyone interested on what is going on on my end !

Thank you, this one will be very interesting to hear the details.

Please don't think that I was questioning what you were told; I simply worded it poorly.

What I would like to see is for dealers and owners to work together to figure out the reason for the problem. Once that is known then I'd be surprised if we couldn't come up with simple measures to protect against this happening to the tractors right now this winter. We could do that while Kubota is working on a more permanent fix.

Does the crankcase vent have a obvious restriction that could freeze or a low spot where moisture could collect? Without seeing the system I'm just guessing one could block off where the vent connects to the intake and run tubing to atmosphere instead, like tractors used to have. Maybe I'm making this too simple without seeing how it's set up b

 

[rabcon]

Yes the old way there where no isuse with the venting tube freezing shut !!!

It sounds like pulling the dipstick may stop this type of runaway. There may be some spray when pressure is released.

It shouldn't as the 5100 it a different tier engine. It sounds like it is specifically related to the 5200 Tier 4 engines.

Seems like tier 4 is more like for tears.

Seems like the dipstick would blow off its own if crankcase is positive. Oil filler cap would create more venting.
