mm 5star power steering control valve gaskets?

Postby chrisaukcam » Thu Sep 24, 2020 5:50 pm

I have a leaking power steering control valve on my MM 5 star (1959). It is located on the tractors left front. I took it off and see where a rubber seal has bulged out and the fluid is leaking. I figure that I might as well replace both rubber gaskets and the o-rings while I have it off. Where is a good place to find replacements at a decent price, or would a dealer still carry these?

Thanks for the tip on the parts. I called them and got here fairly quickly. I got some time to put them and the leak stopped. However now my tractor won't turn to the right. It will turn to the left OK. So I must have done something wrong when putting it back together. Any ideas on what needs done?

The control valve location will impact the ability to turn. Loosen the bolts holding the valve and shift it fore/aft a bit and retighten and try again. You may have to try this several times. The finger on the valve also gets worn over time and can impact performance.
