FX22D Power Steering

[HLC3]

I bought a Yanmar 3 years ago, other than a couple hydraulic lines and battery problems nothing bad to say about it. Until the power steering problems. I actually think it was going bad when I received it, knowing nothing of Japanese tractors and what to expect. But the steering felt funny from the start. Now it's basically non existing. I use the rear brakes to maneuver around the acre and only use it an hour or so a month right now. What I need is some thing on the power steering, diagram and some pics would be nice. All the systems I have reviewed are pretty much the same, generic. I don't know it this is a aftermarket or original steering system. Short of starting to disassembling the engine compartment and tracing the line I hope to find more info. I only bought the operator manual (Murray Publishing) and that of course has just minimum info.
So my questions: Does the system use fluid from a separate reservoir or via the transmission? Is there a functional manual for purchase for this model?
Know what this is?

I'll take a guess at it... from the looks of the pic..It's original ( from the factory) with it's own hyd oil tank... Someone my come along and prove me wrong, but that is the way it looks in the pic.

I don't think that is an original system. The reservoir is in the correct location but that is the wrong tank. and wrong lines. My computer has a virus and I can barely type this. PM me and I will get back to you sat when i'm at work.

Do you have a pic of original or any diagrams showing this model w/PS? Thanks for the comment; one for original and one against.

The FX22 did not have an external cylinder like that. Only the bigger (FX26 and up) models used an external cylinder. Diagram from FX22 parts book-

Thanks for that info. First I need to look at the model on the tractor again it's been 3 years since I looked. Then order manuals

 

[runningbird]

yes Double check the model, but at any rate that is not an original system

PS Fluid, anything special about the fluid? Same as auto PS fluid or same Hydraulic fluid used for the rest of the tractor?

Couldn't find anything to designate the tractor as a FX22D except the big letters on the side panel "FX22D". If this isn't original PS then it uses the original Pump? Still need to know what type fluid and how to measure the level in the reservoir when adding?

I'm sorry but from the two pictures you show I don't see how to check the level. It appears to be a closed system, if so you could use auto p.s. fluid. or atf .
Do you have a picture of the whole side of the tractor?
