Does anyone have a Part# For a shorter Belt?

Reply #31
ok,, good deal

i measured mine and it sill measures 77 1/2'' long.

no stretching to this point although summer time may be a little different or even a warm motor.

glad to hear you got the belt,, i am going to change the drawing later. 

now you see what i mean by sayng a 78'' will work?

i guess the range is 77 to 78 actual inches.  a 76 may need pry'd on but still may work.
gotta get mine back on before dark.

76.5 was the first belt I tried while ago at auto zone and it was 1/2" short from the alternator pulley..... Thats when they told me they didn't have a 77" 6  rib..... They had a 77" 7 rib.... but, to get the 77 on I had to take a screwdriver while I was pulling up and pry the tab out of the way just enough  for that extra 1/2 of pull i needed to get the belt on.....

Ok, so if I have the old style tensioner, not the spring loaded one, same belt sizes?  Is there an aftermarket part or something easily adapted to replace the old screw-down style tensioner?  I prefer the spring loaded ones because if something gets trapped in the belt (rag, tool, etc) while the engine's running, it doesn't snap the belt or damage a pulley or break off a shaft.

ahhh,,
i did that type to...
here is what you need to do and my engine was a 3.8 w/ deleted AC.


leave all your smog stuff on the car.

leave the belt on the car
loosen the three bolts that hold the smog pully on
loosen belt tensioner and remove belt.
remove smog pully
pry off this little fan looking thing on the very front of the smog pump.

now,, use a string and pull in the string to measure the total lenghth belt you need.

when you install the belt,, the belt itself will just ***barley clear the smog housing.  dont worry though because it clears enough (a hair).  Mine actually touched but as soon as i started the car, the rotation of the belt shaved itself down on the smog housing ,,ended up working our perfect.

just pull your string in around all the pullys like factory then go hunting for that belt size.

good luck man

Hy just wanted to share but I have Dayco 5060850 belt and I don´t have smog pump and I have BBK underdrive pulleys It goes like this start at A/C --> Power steering -->Water pump -->Crankshaft -->Alternator --> belt tensioner --> back to A/C  Just wondering that maybe different choices can be good cause shortest belt I had was this 5060850 belt and that´s how I find that combination.
