Hi rebuilding athe water pump on my old 955h, hoping someone might know what the tension of the main nut that holds the main belt pulley to the shaft it is a 77A231, also wanting to know what length belt to use.
thanks 
KEN

Nut torque is 85-95 ft-lbs.
In going by  the 77A s/n equivalent to US 60A there is an overlap of two different belt lengths (Matched Pair)
It's either a 8M1714 at 66.50" length and 0.69" width or 4S7754 at 64.50" length and 0.69" width.
