MX5200 Engine Problem

Sure- dismount, open hood, find and remove oil filler cap from screaming, belching runaway diesel? Piece of cake.

If it were in my barn with 1000 round bales, all my machinery, calves, tools ,,,, yes, piece of cake.

I have been told that in Kubota Canada has a mandatory campaign to update all MX model tractors with the CCV system using the oil separator canister. Problem is being caused by condensation accumulation and freezing within the oil separator canister and vent on the valve cover. When the canister freezes the pressure builds within the crankcase and crankcase oil starts to push past the turbo seals into the intake system. Update kit includes a heater system to prevent the CCV system from freezing in cold ambient temps.

That's great news!

Can freezing condensation affect any of their other engines? Looking at the parts books, I see that several models share Kubota's V2403 2.4 liter engine block and they also share an oddly complex vent mounted on top of the valve cover. The vent looks like an old-fashioned vent tube leading overboard & coupled with some filters and a separater. That much is all standard motor stuff used on motors for 50 years. But then there's also what looks to be a barometric switch of some sort that may turn venting on/off. .... I wonder about that.

The M59 is interm tier IV and I believe the MX5100 is too. Depending on what components are shared with the MX5200.....but, if they all share the same vent on the crankcase - and if that is where the freeezing happens - then given the "just right to be wrong" moisture and temperature they could have a similar problem.
I'm guessing it isn't a problem, but surely worth looking into.
If you hear anything more we'd all love to hear it. Good on Kubota for getting on this.

thanks,

This freezing issue is same problem I am having with my L6060. My dealer warned me about it last winter. I was advised to take the canister apart each time I use it and wipe the condensation out out it. They have been using all the update kits on the new tractors leaving the dealerships so I am told. I am waiting to have mine updated but they have been "back ordered" since early January. I guess I was lucky that it did not happen earlier to me, it must not have been that cold out up until now.

Kubota and their dealers have known about this for well over a year and it sure does not seem like they are moving fast enough for me to fix this problem. I use these tractors commercialy and lately I have not been overly impressed with quality.

The MX 5100 is a tier III, well at least the on that I have is. That is the reason I purchased it when I did. I purchased it August 2011.

I bought mine in August 2012. What a great tractor.

Should be Tier IV Interim I'd think, unless it was an old model. Tier III was phased out beginning in 2011 when Tier IV interim kicked in. Tier IV final came in for 2015 models.
