What size belt do I need?

cliff45890 · 10-07-2009

Hello,

I am deleting my smog pump and my A/C. Well moving the p/w pump to where the a/c use to be. I already have the correct belt for the smog delete, but will my belt still it after I install my A/C delete kit? I am also installing an aftermarket alternator bracket with adjustable rod ends. I think I will have a bit more adjustablity for belt tension with that. Thanks.

Use the tried and true string method......

You will probably need a shorter belt.. + 1 on the string method, it is going to be the best way.

i have no smog pump without the delete braket with a/c delete with the power steering moved up in its place with a march adjustable alt bracket . my belts 64" a 63.5 wouldve fit even better, i used the string method and just bought a few diffrent sizes and returned the ones that didnt fit

X4 on string.....like fox said, after measuring it, get a few belts...one a little bigger and one a bit smaller...and return the ones that didnt fit.

Same set up w/ UPR water pump pulley and Crank pulley w/ undersized alt. pulley 63.5" belt.
Figured i was the only one w/ that cobbled together setup but it looks so much better.

I have a cloth measuring tape from the sewing department at walmart, I use that to measure for my belts. make sure you get the long one, the 5 footer won't always do.

I went to Autozone and picked up Durlast part# 635K6. It's a 63.5 inch, 6 rib belt. I am doing the conversion this weekend and I will keep you posted on the results. Thanks for the info.

That belt did not work for my setup. I have to go back and get a 65 inch belt.

That's how long my belt is, 65 inches. For those who don't know, I have the March alternator bracket, no smog pump, Ford Racing AC delete kit that moves the power steering up.

The 65 inch belt worked very well. Perfect fit with enough adjustablity. Thanks for the help.
