So you calculated you needed 73" and got a 73" belt and it was too short.
Hmm, sounds like your calculation is off.
How did you calculate the length?
I always recommend using a length of string routed the same way the belt would go around the pulleys to get close to the size you need. Measure the string after you wrapped it around the pulleys and get a couple belts within 5mms of each other so you don't have to keep running back to the store.
i got the 73 from this graph but it was to short and a 73 1/4 was to long so i thought is someone had this
i feel the same way but the 73.25 slightly touches itself at the tensioner. i asked the parts store guy how the hell could a 1/4 in change go from too big to too small and his answer was to try to get a part number and try that. the 73 was a double side 6 groove belt but it did say 73 in. i dont know i just want a damn belt on the motor.lol
for stock pulleys on a fox 5L with the smog pump deleted (not around the pulley at all, not just the delete bracket) uses an 87" belt... i have underdrives on mine and i use an 83.5" belt
i dont know how you guys are using sub-80" belts...
please elaborate...
yeah i started with the string but it did not work because i got a 68in belt and it was way to short. i got the 73 from this graph but it was to short and a 73 1/4 was to long so i thought is someone had this setup they may know what the part number was
