Hi

Anyone ever experience an RTV900 power steering just quit?
No oil puddles, Hydraulic pump still works, steering wheel just goes around in circles, no stops.
I can barely turn front wheels by hand, Right front wheel has a lot of play by hand turning right to left, etc, left side not so much.

Steering was wandering driving down a straight road for quite a while.

I hope it the cylinder, less to fix and may help the steeering wander.

Are their checks I can do to determine which is bad?

Thanks for any help/

As the Dump works, It is not the Pump

A friend had that problem. He had water in his power steering fluid.

Anyone have a service manual they could PM the troubleshoooting section?

Fairly certain it is one of two possible problems.

A,) The Earth's climate is going Flaky!
Saturday -17F , wind Chill about -35F.
Today, 47 F , 60 Mph wind gusts. Very foggy.
That is a 60 F difference in 48 hours.
I think the Kubota RTV900 Hydraulic resevior vent lets moisture in the oil, and the system may have froze up. Our equipment building is still about 30 F on the inside, and all the equipment is really sweating. That's not good, as the insides of the engine, etc, collect water.

B.) Steering cylinder went south, I think the controller and pump are ok.

Once it warms up, I'll have my answer snd i will post.

Does anyone know if the RTV900 has a two section hydraulic pump, i.e. inboard feeds dump cylinder and outboard feeds the steering??

My 2007 RTV 1100 has a two section engine driven pump some of the early ones drove off the transmission. They came up with a new trap type vent as the ones with the red cap were sucking water in to the tank.
