Install was easy and it works great. I don't like the rubber end on the joystick, the original had a knob that was much more comfortable to use.

Thank you for the feedback. I've forwarded your message to our Operations Team so they can discuss further.

I know a lot about my antic tractor :but :recently my front end loader fork got to where it would not hold pressure. I had never had this happen before. Like most of you folks, I went online to get some help…(so much advertising now days-more confusing)…I finally got to speak with a real machnic with actual OJT.and not someone reading from a service manual.:his name was Mike.He didn’t have to take the time to explain my concerns..but he did (very rare now days 👍).so: I don’t know you and you guys don’t know me but I Really Recommend you contacting Mike at this company if you need help…….ps…. I hope I don’t get Mike into trouble with his Boss by telling how much time he spent with me and I didn’t even buy anything 🥴…….but I will if I ever need anything……thanks Mike 🇺🇸☕️🐄:Ernie from Alba

Thanks for the feedback! Wonderful to hear about your experience with Mike.

    Thank you for reaching out! At this time, we do not have a rebuild kit for the Hydraulic Valve with Joystick. 

    Please let us know if you have additional questions or need anything else. Thank you.

  • Do you have a complete joystick kit for a Massey Ferguson 3545?

    Thank you for reaching out! We do not have a Complete plumbing kit for that model Massey.

    The only thing we can offer is the starter kit, which gives the basic valve, joystick w cables and cable connectors. It would be necessary to figure out where to mount and how to mount both joystick and valve, plus fittings, hoses, and hose length. Our Customer Service Team is available at 1-800-557-4689 or 1-605-336-1750 if you'd like to discuss further. Thank you.
