One belt or two?

[one_dusty_hoot]

Just pulled the radiator on my 77FC31 and examined the front end of
the Cat 3208NA.

The fan with a viscous clutch had two belt grooves that aligned well
with two on the drive pulley, that being the crankshaft.The groove
without the belt was rusty as the result of not being used. The
existing belt, a Green Stripe Gates (9430) was not cracked, chaffed,
or badly worn in spite of being in service for 18* years. The Krikit
gauge read 50#, a few pounds low but expected for time in service
without adjustment.

Right now I don't know if I lost one or didn't put one on to start.

A safe answer would be, Sure!, you got two grooves haven't you? I
would like to know what others are running here, one or two belts.

Thanks,
