Went to look at these today. They are both three stage mast short chassis tall counterweight solid tire clark model c500-s100, so only 10k lifts rather than 15k as advertised, probably 1989 or so. The one I thought was dual tire appears to have two tires pressed on to each wheel. Both machines are in pretty bad shape, one also has a mast leak and poor chrome (but not pitted) on the tilt cylinders. They both have Perkins 4 cylinder LPG engines. I'm still interested; are parts still available for these engines? rebuild kit? what does a mast cylinder cost to reseal? They have the short center cylinder with two tall outer cylinders and side shift. Neither runs or has brake pedal resistance, of course, but there was oil in the engines and some coolant in the radiator, and one or both need starters, tires, batteries & have had rodents work on the wiring. The one I'd prefer has 6xxx hrs on it (5-1/2' forks, mast about 7' down, 161" lift, stamped 5700lbs at 42"LC which I guess would be around 9900 at 24", the other has only 24xx hrs, 6-1/2' forks, mast 96" down, 189" lift, stamped 8350lbs at 24" lc. What's the "'I'd have to be an idiot to not buy it" price? I can fix anything, and I have the time, but if there is a red flag on any potential parts required either from a no longer available (or priced that way) perspective I'd like to know...and buying both is not out of the question if it would be worth it to restore one for resale and keep the one I want. thoughts?
