I'm getting ready to install PS on my '40. I took a good look at the harmonic balancer, it's got two grooves, but the one closest to the radiator is considerably narrower than the one currently running the alt and waterpump. Are there two different sizes of belts? I ASSume the smog pump ran off the front groove? If all I'm going to run with the front groove is PS pump(Sag), then I can probably use a GM pulley instead of looking for a Volvo pulley?
It also appears that there are some impending issues with the fan interfering with the belt. I'm running the old 4 blade metal fan, but have a later model 6 blade plastic fan. The motor is a late '74F, like F and a half, I've heard it called, desmogged by PO. The truck is a '66.
Anyone out there/ Or is everyone mowing?
