I have a 1973 Otis Baker FJF 040 and it has an Allis Chalmers 4cyl flat head motor. It's leaking oil behind the crank pulley. It runs great other than spitting oil from behind there. Does anyone have an engine diagram or how to remove the pulley? It doesn't appear to have a nut holding it on looks more pressed on?

How can I post a picture?
The crankshaft pulley should have a large headed bolt. It is not threaded or press fit. It sounds like the bolt fell out and that is why it wobbles. There is a seal behind the pulley. Check more closely.
Do you have a way to send pictures?
Somebody seriously Mickey Moused this machine. What is the diameter of the front and rear tires? 15" or 12" front, 10" or 9" on rear. If 15" and 10" then it was originally outfitted with a 6 cylinder F227 engine. No matter, someone took an engine out of an Allis Chalmers forklift truck and installed it in this truck.
The tag on the motor says manufacturered by Allis Chalmers for Continental. F163. This forum won't let me post pictures but the bottom pulley which looks to be on the crank wobbles when the motor is given gas. The pulley doesn't have a bolt and is flush.
If it has a 4 cylinder engine it is not a 1973 FJF040 or has an Allis Chalmers engine. It must be a lot older than that. It is either a Hercules or Continental engine. In either case you will probably have to remove the radiator to access the bolt.
