i just installed my 1st gen jrsc and when i was putting my belt on i realised the ac pully was stuck..it wont budge..im guessing the pully bearings are out..i then grabbed the belt i pulled off my car during the install and realised whoever i bought the car from 3 months ago put a smaller belt on the car and bypassed the ac altogether..now i have 2 belts that are waaaay to big to install into my car and i have no idea what size belt to buy to bypass the ac with the 4inch jr pully on the blower/stock crank pully..anyone else ever bypass theyre ac? its real cold this timer of year in colorado and i really need to get my car drivable ac or not..if anyone could lead me in the right direction on what size belt i need to bypass my ac pully it would be much appreciated.once i repair the ac pully bearing i have the belt i need..right now i need to get this car out of my friends driveway lol..btw the install was a snap..alot easier than i though it would be...i just wish i could drive the damn thing...thanks- joep

Your ac compressor probably went out like everybody else's. I ran a 62" on a 3.8" pulley with ac. Get a string and go around the pulleys then measure that thing.

damn i never thought of that..thanks..what about the auto tensioner? should i shave a 1/16th off that measurement so the tensioner is tight enough to keep the belt from slipping? -joep

100% agreed. Also look for old threads from Theta. He owned a Ep3R in the Netherlands and was running a JRSC without A/C for quite a while.
