I just got my stang and the motor is a 302 out of a mid seventies bronco (so I am told). The belt setup on it is a mess. The guy I got it from just tried putting a new tensioner and the disconnected AC pump back on it because the previous owner had taken it off and had the wrong tensioner with the belt aligned creating the waterpump to spin backwards (so I am told). Anyway I do not want the big ac compressor on the motor. Its useless weight, taking up space, and worst it has a bad bearing so makes a terrible racket. I don't even know if the guy I got it from hooked it up right. The first day I had the car it threw a belt because the alternator spun a bearing and the pully just got completly loose. I put a new alternator in and put belt back on. It doesn't seem to be overly tight (not sure how to measure for proper tension) but my guess is either the old alternator was just wore out or somehow the setup that the dude put on here is creating over due tension on alternator. I don't have a digital camera yet or I would show you the setup. Maybe some of you out there could give me photos or ideas. What length belt? Is there a AC delete pully I can put in the compressors place? Can I just remove it and reroute my belt? Oh yeah the belt is currently a 79" and routes (left upper) alternator (just to right of that) tensioner, (upper center) water pump, (upper right) AC compressor, (lower right) power steering pump, (lower center) crank. Hope that gives you an idea. Any thoughts would be appreciated.
