Re: HELP. How do you adjust the V-belts on a 48 flathead?
The belt tension for the generator and water pumps is separate from the fan belt. Loosen the two bolts holding the fan belt and allow the assembly to slide down. Then loosen the large "nut" holding the other belt and adjust to the recommended tension. Next, raise the fan assembly until the belt is tensioned, then tighten the two bolts holding the assembly. Dom't over tighten either belt to prevent damage.
