I had a couple just like that - they were 2000 lbs. I don't recall the model number. I think the one with the tall mast like yours was actually de-rated to 1500. My other one had a short mast and it was 2000.
I had another that was 3,000 lbs and it was larger.
That has an aftermarket aluminum steering wheel and mag wheels on it and someone put a grille in the air scoops - I've never seen that on a forklift. It also has some kind of funky propane tank on it - not sure I like that.
They just have continental flat head 4 cylinders in them - about the simplest engine to work on ever made. They are pretty robust engines, especially running on propane. I wouldn't think they would need rebuilt. I had one with a stuck valve one time just pulled the head and worked it manually to get it unstuck and it ran fine. One thing interesting, one of my 2K ones was a couple years newer than the other, and the engine, which looked identical ran the opposite direction of the other.
You can get Lowe's to mix up the Clark Neon Green paint - I forget the code number but it's easy to find. They have cans of Valspar anti-rust which can be mixed to any color - nice machine paint used by several OEM's.
The only problem with those lifts is they lack power steering, which is why I got a newer one. They are really compact and handy though.
