Craftsman TS belt tension increases w/blade height

Greetings,
I just got a "bargain" ;-( TS, model 113.299040 and am trying to figure out what causes the belt tension to increase to the point of binding when raising the blade. V-belt is the correct 1/2X41 belt, and a cursory exam doesn't reveal anything busted. Any suggestions appreciated.
Thanks!

Can't find out about this model at Sears.com, I wonder if the motor's mounted on pivots, to use the weight of the motor to keep tension, and the pivots are bad?Tom >T.C.Monson wrote:

Maybe some pivots are bad? Can't find anything on this saw at Sears.com. Tom>T.C.Monson wrote:

Yea, see if there is a slotted hole, like on a car alternator. The bolt could be too tight. Should be back where the motor pivots. Loosen it up a bit. Tony D.

The part of motor holder that bolts to the motor pivots on a hinge and there is a slotted part on the side that has a bolt through it to reduce vibration. If the correct washer is not used or the bolt is two tight, you will experience the condition you described. This bolt is meant only two reduce vibration so it shouldn't be real tight, in fact it isn't really needed.
The other possibility is that motor holder is adjusted out so far so that there is no room for the motor to swing on the hinge. If that is the case, loosen the two bolt that hold the long rods of the motor holder and slide the assembly toward the saw so that the motor hangs lower.
