I saw this adjustment screw near what I think is the tension screw for some of the belts on my engine. It is the CAT 3208 turbo and intercooled. Anyone have any ideas? I think it was some sort of jerry rig(sp?).

The component I am talking about is the t handle looking crome thing that is right next to the belt in the picture. The second picture is zoomed out for reference on the engine. By the way when the engine runs the component shakes and hits the belt as it rotates.

by the way the pictures are rotated 90 degree clockwise for some reason.

looks like the belts are too long, like a cap screw and that other thing were stuck in there to get tension on the belts while the hold-down bolt was secured on the slot.

whoops... now I see that it is not a cap screw, but a bolt through a threaded lug and with a lock nut. Never the less, there is no more travel because of belt stretch or wrong belts.

After a year of surprises on the road when the belts would fail I called Gillig and they confirmed that their belts were a proprietary design because of the long distances. I had several CAT service centers put on belts and they continued to fail. Once I got the Gillig belts everything was corrected. The book on the engine provides the tension adjustment for each pair of belts and you can buy the tools for about ten bucks each. With proper size and proper tension I have had three years of boring and thankful non events. I still bought two sets just to be safe.

You're at the end of your adjustment travel. Replace the belts and remove that "T handle" thing that's in there. Save your old belts for a "Just In Case" scenario or buy 2 sets.
