I just order the set of underdrives pullies got 3 of them all aluminum, what size of belt is needed to run them?

 

Goodyear Gatorback belt # 4070950 which is a 7 rib belt at 95" long

 

how long did it take you to get off all three pullies and new ones on?

 

i only run the crank pully, at frist about 10min tops...... the alt pully cant be a little hard to get off i used a air ratchet,,, but you should have the crank, alt and the new belt on in 10-15 mins

i dont know about the waterpump

 

so the belt number you provided was only for the underdrive crank pulley?

 

it will work for both,,,,,,,,, but i had a hughes underdrive pullys
