If I would like to remove my smog pump and ac compressor and install a shorter belt what should I do w/ the tensioner it won't work well were its located stock. What else should I know before doing this mod? I had the cats removed and would like to get rid of the smog pump as soon as possible.

Tensioner problems

Thanks for the new diagrams. Does the tensioner work w/ out any mods and what do I do w/ the rest of the smog equipment specifically the ports into the back of the heads?

You can just install some plugs in the holes. I can't remember the size, but there are matching holes in front that your accessory brackets attach to. Pull the bolt to get the correct size. My aluminum heads came with plugs in the front and rear so I can use the pair I removed. It pays to be a pack-rat sometimes ;-)

BTW - someone (Josh or Jason I think) mentioned a good way to get the correct length belt...take your existing belt and route it the new way...then with no tension on the belt, use some vice grips to pinch the belt to the right size. You should be able to then see if the belt is tight enough under tension. You can then take it to the parts store to measure or match up with one the correct length.

The vise grip method was my brainchild.... it works flawlessly, assuming of course you actually pay attention to what you're doing! In any case, I removed all of my smog gear, I went with the idler bracket from ford. The belt routing diagram above isn't quite right since the tensioner is in a different place.

The cheapest thing to do about the smog holes in the back of the heads, it to cut the existing little blocks off their lines, then simply weld the holes closed and bolt them back on. A machine shop won't charge you more than $10 for doing this. The hardest part is getting back there to take them off and put them back on, luckily for me, I had the engine yanked when I decided to do this.

Hope it helps

Sorry Jim, I apolgize...I knew it began with a J! Anyway, that method is much more reliable than the old string method, unless you don't own a vice grip :eek:

Which diagram are you referring to? The top one is incorrect, but the one in the link is correct as far as component layout goes, he only has the rotation wrong but states so...I'm going to try it because it's easy and mostly free, I'm just concerned that there won't be enough tension on the belt running it that way (without the smog pump delete pulley).

No problem, I'm just glad folks are able to get the correct belt size easier than they used to :)

I seem to remember thinking that I would have major problems w/o the smog delete pulley and that the tensioner wasn't going to work well w/o it... but I could be wrong. I know for sure it works with it though!! Just like I know NOT to go to a flaming river manual rack and pinion! lol

Thanks

I appreciate the replies, some of this stuff (smog removal,etc) gets repeated so much but is still helpful for us rookies.

Just as an FYI for anyone reading this thread, the belt lengths should be taken with a grain of salt. Neither the 900K6 or the 895K6 or the other Gates part number that has been posted here do not work on my 93 bird.

I tried all three today.

I just put on a GATES K060926 on my 93 5.0 to bypass the smog pump only. You do need to route the belt differently, but it goes on fine, and I was able to use the tensioner. I used the routing diagram from the stallionmotorsports link above.

You can buy the little plugs that go into the back of the head from Motorsport. Like If you can make it to any of the NMRA events, they ALWAYS ALWAYS sell them, or someone there at the swap meet part is sure to have them. Not sure of the PN, but you can buy them from Ford.

Just verifying the K060926 no smog belt. My frpp '93 stang shorty headers will require the smog pump and egr be deleted.

This belt fits exactly right? Will the tensioner be in its proper range?
