i need help finding a part number for the belt that just runs the alternator to the waterpump and crank on the 93 motor

 

this belt runs an air pump aswell if im right, according to fiche if its a M/T car, belt is a 5pk1355 or 5pk1310 if A/T dont ask me why theres a difference

 

hopefully this helps

im running underdrive crank alt and waterpump only. i just ordered today from a shop the smallest 5 rib belt they can get which is 29 and 5/8. im quite sure that will work. i'll let you know tomorrow night when i get back from my shop!

 

I have the underdrive crank alt and waterpump to ,Gates micro-v ko5o290. I had to extend adjustment slot to get proper tension. The easy way to extend slot is drill bit the same size as slot and diegrind or file the slot.

 

I couldn't get the 29" to work, but then I didn't extend the adjustment slot like Busted7 did. www.pettitracing.com sells the belt but I can't conenct at work for the link. K2RD used to sell it and Rotorsportracing.com still sells it seperately as well.

 

I don't have the part #, but I found the shortest AC delco belt to be a perfect fit.

 

We carry 5 & 6 rib belts for almost every pulley combination

I am running a Dayco 5050303. This belt is 5 rib and 30.5 inches. I am running a pettit (rotor shaped) alternator pulley, the same waterpump pulley as Busted 7 and a single stock underdrive. Odd combo, but it works great.G

 

update! that 29 and 5/8 is to short lol. im just going to bring the belt that i had on there and this one i just purchased from them and say i want one thats inbetween the two. might try getting a 30, 30 1/4, and a 30 1/2. one of those bitches has to fit for sure. im not sure if they make a 30 and a 1/4 though

 

I dont think so. The only one I found was 30.5. In between 29 5/8 and 32 (5 rib). Even that size had to be special ordered. Will not find it at a local autoparts unless your lucky. G

 

^ advance auto had a 30.5 in stock i didnt get it cause i thought it would be to long that might be just the trick. its funny though cause he measured my 4 rib belt that i had with me that was just a lil too long and said it was 30.75 lol which did not believe but wasnt about ot argue with him after he used a tape measure and did it with the thing not streched out tight. so i guess i'll just run and get that 30.5 and hope for the best here! thanks for the info again

 

Cool. Advanced is also where I got mine, but had to be shipped from an Alabama store. Good luck w/ it. G

 

******* sold the damn thing somehow... and its a computer relist item! isnt that some horse ****... i guess i'll just have to order it from and online belt company or just some place with a large listing of belts. any suggestions?

 

I just go here http://www.pettitracing.com/rx7/index_performance.htm and pick the belt i need. Then i just click on the image an take the number. Some are Goodyear Gatorbacks and the others are dayco for the underdrive pulleys. I called mine into the autoparts store and got them the same day.

 

Damn! That sucks. Pettit's price is double than auotozone's for the same thing. Geez..
