WHen the timing belt tensioner bearing is bolted down should the adjustment bracket be able to move when the long stud bolt in the adjustment slot is loosened? When I tighten down my tensioner bearing I cannot move the adjustment bracked without loosening the bearing bolt even with the the long stud bolt loose in slot. I'm wondering if there was suppose to be a washer behind the bearing bolt and bracket or is this normal?

Normal. The timing belt tensioner Is Not spring loaded like a riding lawn mower blade engagement pulley. Loosen bolts, spring sets tension, bolts torqued down, timing belt tension stays, spring does nothing from there.

thanks snowfish I was a tad zealous and felt I over did it on the belt tension the other day as I heard a low hum around the timing belt , so I had thought I discovered a short cut to adjusting the belt tension through the rubber peep hole using my 10mm little wrench. I got the long stud loose through the peep hole but the darn bracket with slot wouldnt budge . So I had to take it all apart again to get to the tension bearing bolt which actually releases the adjustment slot as you mentioned. I've been thinking of making a little 12mm window on my timing belt cover that allows access to the tensioner bolt. Maybe next time I take it apart. Not a great time to modify things as I'm visiting family here in southern Minnesota. Thanks much

Why? It doesn't need constant adjustment. You set it and forget it.

some people remove the spring and adjust tension by hand. Then there is no way the spring will get loose and fall in the belt and screw it up |

Yes, I removed that spring as well. Seems like a risky idea from the engineers to have a loose spring hover an inch over the inside of a timing belt . Do timing belts stretch a tad over miles and time?
