Does anybody know how to replace the fan belt on the Nissan 80 forklift which has the TB42 motor in it? I can see that it has 3 seperate belts on it- Alternator- Fan- Governor- but all is needed is the Fan belt which has been broken off. There is a shaft attached to the Crank pulley with 4 bolts that goes to the hydraulic pump-I think- cannot see too well inside the compartment- does this shaft come off or seperate from the crank pulley easily?
