8010 power steering

Message Topic Search Topic Options Post Reply Create New Topic Printable Version Translate Topic


   Greetings all,Hauling silage wagons with the 8010 this weekend, and started to have trouble steering.  Tractor wanted to drift to the left, and was slow/unresponsive to turn back to the right.  Eventually, I lost all steering to the right.  
Reading information on the forum here, someone had a similar problem with an 8030, and the likely culprit was the orbital steering motor at the end of the steering wheel.  I am guessing, that after 9000 hours, a seal has blown, or some orifice is plugged, not allowing flow to the right turn valve.  
I see both used and new motors for sale online (Dealer, TractorParts ASAP, etc).  I also see that there is a seal kit part number shown on the partsbook.  
If this is a seal issue, I can replace the seals for less than $100.  If this is a bigger problem, the motor looks to be about $700 after the core charge is returned.  

What do you all recommend?  Rebuilt, replace, or am I barking up the wrong tree of symptoms?  

Thank you
John

	Re-seal the steering cylinder first. I suppose the leaf springs inside the steering control valve could be broken but I've never seen that yet. The other poster has never responded back. Edited by DrAllis - 06 Oct 2024 at 6:39pm

	Dr. Allis, Thank you for the reply. I did see in the other post that you mentioned removing the hoses at the cylinder, and capping them. Then try to turn the steering wheel. If I can't turn the wheel, then it is the steering cylinder that is bad. I am looking through my hydraulic fittings to see if I have some caps for the lines, and I will test that. Thank you John

	Could a guy reverse the hoses on the cyl and see if the problem is still the same direction, thus pinpointing an internal cylinder leak vs a orbitrol issue? There's not really any seals inside the orbitrol , it's all sealed inside by metal precision fit.

	I apologize for the delay. It took me a while to get time to work on it, and lost track of time. I followed the instructions, and disconnected the hydraulic lines at the cylinder, and then plugged the lines. The steering wheel did not turn, so it was the cylinder. Got a seal set installed, and then re-installed the cylinder on the tractor. Everything is working again. Thank you for all your help. John
