Trying to help a friend figure out what this part is on his old Nissan FG003 forklift (and what it does). It is belt driven but doesn't have any hoses or wires coming off of it but does have linkage that connects to the carburetor. It's seized right now so he needs to figure out what it is and does to get his forklift going again. I had him shoot me the picture below and this is what I know about the forklift: Nissan or Datsun (has badges for both) model #FG003, Engine #D11K0865, Chassis #FG003-5002 & capacity: 3,000lbs. I have been putting my feelers out on any forklift forum that I can find but no luck yet.
