What belt to use when removing smog pump?

[Tasandmnm]

One of the tubes is broken and the pulley on my smog pump is kinda wobbly so instead of fixing it I am just going to remove it from the car. Anyone know the correct length belt to use and maybe a part #? Thanks.

760k6 if your running stock pullies.

Hey mouse what store would that be at? Also I should have mentioned my car is a 1993 Cobra with stock underdrive pullies.

Just get a peice of string and measure. The cobra has a factory underdrive water pump pully, so it will be a different belt than a normal 5.0

You also need to change the belt routing.

is there any drawback to just by-passing the smog pully and leaving everything in and hooked up.

You shouldn't really do it if you have cats, but i've done it with no probs for a while.

Ok but how do I take the belt tensioner into account when measuring?

Pull it tight ignoring the tensioner and then add an inch or so.

Then go to the parts store and buy a few lenght belts. If you don't know, the last 3 digits of the part number are the belt lenght. So if it's GDYR80845, then it's an 84.5" belt.

Test fit the belts and pick one that fits on the tight side of the tensioners range. It will stretch a bit when it breaks in.

Then return the rest. I usually swap the belts in the parking lot that way i can return them all and get more if they are wrong

pull it as far up as possible and measure it like that. FYI I got an 84 1/4" belt to work on mine, smaller usually = better with belts, they tend to stretch out.
