tensioner pulley

[CALL AAA]

How do you remove tension from a belt, if you don't have the little allen nut on the tensioner pulley? I just looked at my pullies, and neither one has a place for an allen wrench. Just the nut on the outside. How do I undo the pulley without it?
Thanks
Tony

You have to loosen the nut to release its hold on the mount, then above it is a bolt that you turn to make the bolt go up/down, it is 5mm allen if I recall correctly, once it is where you want, retighten the nut, recheck after some miles just to be sure it is not too tight/loose.
The power steering one can be fun to get to, since you have a 92, it probably has teh mount tha makes it more accesable, my 89's is a pain in the butt to do.
Good luck

Oh, OK. I must be looking in the wrong place for the bolt.
Thanks.

Tony,

In front of the tensioner pulley is a 14mm nut that holds on the pulley, and locks the tensioner/pulley in place. Loosen the nut a couple of turns. Behind the pulley is the tensioner mount, and on top of the mount is the "jack screw" with a 5mm allen head.

Using a 5mm allen wrench, turn the screw clockwise to tighten the tension, or counter-clockwise to loosen the tension. To remove the pulley, remove the nut after you have reduced the tension on the belt.

The nut gets tightened to 25 ft lbs torque, after you have adjusted the belt to its proper tension.

If you have a bad bearing in the pulley, you can buy a replacement pulley and bearing for about $90, or you can buy a Generation III SHO pulley for about $30 and press out the bearing.

Then press it into your pulley. The bearing in the Gen III SHO is a NSK BD20-15DWA, which is exactly the same bearing as is in the Gen I SHO pulleys.
Hope this helps, rangerj

Thanks guys. Now that I have been in there and wrenched around a bit, I see how it works. The only other question I have is how tight should the belt be? How do I check it?
Thanks again.

1/4" slack is usually the average accepted amount of belt movement, you'll know when its too tight if you get whining noise which increase with RPM's or if its too loose with a high pitched squeal at idle and between shifts.
