Belt question with no smog

How many itmes has this topic came up?  I have been trolling though treads to find out if someone has a length yet posted.

The length of the 5.0 sefi serpentine belt with no smog is what?  My brother in law says its a 76k6 belt so im starting to think he is right.  He deals with mustangs and they are the same pully setup so maybe at worse case i can do the string thing.


Master blaster found this drawing a long time ago from somewhere but the length is not on here.  I modified his drawing to illustrate what i am doing. 

I may have to let the tensioner lay on the area in red instead of on the  top part of the belt.

does this look right to everyone,,?
the water pump to crank belt arrangement is different with the short belt.

it looks like everything still rotates the same.

Yeah, looks like the rotation is the same to me, too.
Also, reading that text, those belt lengths are for underdrive pullies.
Do you have a link for where you found that diagram?

I agree though, it appears the info is applicable to underdrive pullys only. 

anyone????

The mustang brackets are different there tighter to the motor. Forget what size I used I have u/d pulleys and a/c delete and also the #s wore off the belt. Wrote it down somewhere but don’t remember where. I took a rope ran it around my pulley and measured what I needed.

If you use the rope trick make sure you hold the tensioner in the correct location or make sure you subtract about 2-3" from the length of rope to get the right size. Then be prepared to make several trips or buy several belts. Trust me I work at a parts store and deal with this almost everyday.

That belt routing works just fine. I want to say I just ordered the A/C delete belt.

I did mine per your first post when my smog pump locked up and burnt the belt off. I'm still running this way without any issues. I'm not sure what the belt size is. I drove about 2 blocks to Advance Auto and told them what I wanted to do. They left me try belt until I got one that worked.

It's actually the other way around...I had mustang brackets on my XR-7 and the p/s was so close to the battery, I had to have a little patience when checking my p/s fluid...that's definitely not the case with the 5.0 Birds/Cougars stock brackets.

Yup, true...

Not absolutely sure, but the '86 Stangs may use same/similar bracket to the Bird/Coug???? Seems mine did...

Use the string/rope trick, works(held the tensioner to mid travel while  marking the string overlap with a Sharpie)... I got the correct belt first try...

I come up with 79'' bypassing the smog using a string.  That is with the idler aimed at the 5 o'clock direction.  I bought a 77'' belt and will try it out tomorrow.

also got trans fluid / filter / oil/filter / fuel filter and plans to empty my cat tomorrow.

BTW, i also have a neat bracket that holds my laptop by using a bracket i fab'd up that is bolted to the bottom of the console.  Pretty steady and pvits so it can be swung around for the passanger to use as well.  The bracket is basically a piece of aluminum 3''x3'' angle iron.

If it works let me know :D

I've always wondered if running the shorter belt put stress on the alternator.....
