I bought a grey-market Yanmar F200 in the UK last year- wish I could read Japanese! Has anyone come across this model I am looking for manuals - owners w/shop or other has anyone any information to help. I have no complaints just would be nice to know if I am missing out on any goodies hidden away somewhere. I should say it is 22/23hp 3cyl. 4WD front assisted, rear PTO, cat1 3pt linkage and novel button control of the 3pt links.Any news or views. Thanks in anticipation. Steve

Thanks for the info. Later, I'll replumb, change oil, and check the pressures, but for now I need to continue building the retaining wall I started. Yesterday I rebuilt the loader valve. The detent section of the lift cylinders was partially unscrewed from the spool. I put in new o-rings and used a special o-ring lube on all the parts. Afterwards I resumed working the loader and it is working much better. It now lifts as it should. The bucket doesn't drop when joystick is put into the lift and dump position. It just dumps and doesn't lift. Again, the valve may be too simple or not enough hydraulic flow for that feature. I did notice while the valve was apart, a check valve in a port located in the center of the lift spool and provisions to place one on the curl and dump spool. I'm tempted to buy one to see if the lift and dump is possible. Another thing I noticed, is the fit and finish of the spools and ports. I bet they are matched sets. A true rebuild may require a new spool honed to the diameter of ports. It may not be possible to just buy a new spool and drop it in. I don't know this for sure, just a thought.
