Howdy RCAVSTOR,
Thanks for your reply. Our forklift has the Nissan name on it and I've not seen any Mitsu badging, but of course, that does not mean it is somewhere on it. I contacted Nissan support. They nicely gave some info, but said their computer records do not go back to the late 80's-early 90's which this vintage of the Model F03 is. I located a factory service manual, era '93 on ebay, so hopefully that info will be sufficiently similar to give us some guidance on repairing the tilt hydraulic valve. Since we don't need it and are **** about anything we are selling being in as near perfect condition as we can make it. That is the only thing less than perfect operating condition. It is such a good machine, I hate to let it just sit and be used only 3 or 4 hours per year. Once ready to go, I guess we will put it on ebay. I sure appreciate your taking time to reply and will certainly keep your advice in mind as we blindly tear into this. Thanks a bunch.
Jim
