Hey I was just wondering when we could be expecting the next part of the Kubota v2203 rebuild

[@samburk3635]

I have a “U004334-03, DEF pump pressure max” on a 2017 T770 that was purchased at auction. Need some help with a solution.

[@bluebestequipmentsales]

Thanks!

[@tetradgroup]

Thank you so much for the support!

[@christopherwebber1104]

Us as consumers need access to the software. Until then I hope all these companies fail

[@4211welderman]

Where did you get your software from?

[@miguelzavala3083]

He’s using Bobcat dealer software supplied to dealers from bobcat

[@Dieselguy1922]

I own a heavy equipment repair company and I build diag laptops, I have any software you need. For this model machine you have two different programs that you need to have and two different set of cables to hook to the machine. Service analyzer is for the engine ECU to program things such as hyd control valve actuators, and for cylinder cut outs for example. The program for the DCU is called Bobcat engine analyzer and that is for the tier 4 machines that program requires a special set of cables that will run you $2500. If you could find a dealer that will sell them to you.

Good explain.

[@adamhess7788]

9 minutes in and still waiting on hearing about desox....

[@ArtietheArchon]

making me lean toward a 300 over a 770

[@hunterbiden001]

bobcat = junk

What is the filter part number for 2013 s550 hydraulic filter under the fan, I ordered 3 different part numbers from Bobcat and keep getting the filter that is behind the reservoir. I will send you another super like for your time. Thanks!

[@williamdowey3117]

I was told at the engine gold class for bobcat that you have to go into the DCU and program the new sensor. Cause there are 3 different size tanks?? I’ve never done it. But it would make sense cause of the level. But I’ve replaced a handful of these headers and never had an issue after

A lot of guys up here in Canada offer deletes for these. Just like any place - Bobcat will try and find a way to deny warranty for anything.
