Kubota RTV 900 (2010) steering delivery tube replacement

Howard Dare · April 25

The steering delivery tube running from the pump to the steering controller below the steering wheel has fractured due to rubbing on a sharp steel flange. I would like to replace the tube and I am hoping someone reading this has actually done the job. To get to the point that I have identified the problem I have had to do a great deal of disassembly. The manual implies I must take off the roll cage, the rest of the body, the steering wheel and the dashboard. Is this really necessary?

The manual also suggests bleeding the steering without detailing how this is achieved. Does anybody know how to do this?

This sub forum is not very active. That's good or bad depending on how you look at it, I suppose. I have not encountered the issue your are describing with my Kubota. However, I did encounter something similar in my prior UTV. I did have to remove the body to get to the areas needed for repair.

Good luck. I can give you the number of my Kubota dealer. They are always very helpful with DIY issues.

It is looking like the removal of the remainder of the cab is not too complex. Having taken so much apart to get to identify the leak, going further when assistance is available will be within my capabilities. I will need to discover how to bleed the power steering as the manual only tells you to do it, not how.

If I were buying another UTV it would not be a Kubota. Unnecessary complexity everywhere. Ridiculously expensive parts. Stratospheric annual servicing costs if you use the dealer. Looks like I am stuck with this until I retire as I am 70 now. I got it at 2 years old and it had just had major work on the transmission, having been used by boy racers. The last 8 years have been sedate but I have had to change a front drive shaft and other small items. The steering delivery hose failing because of a design issue would have been totally predictable to Kubota. They probably thought it would be a revenue stream for their dealer servicing network.
