Swamp Cooler NIGHTMARE

A few years back I purchased a home and have had TERRIBLE troubles with the swamp cooler/evaporatvive cooler. I have replaced the motor. pump. pulleys. bearings and just about everything else save the housing and cage. Still the motor turns off after about a half hour on high (sometimes sooner dependant on temperature.) here is my question..... The adjustable pulley at the top (one on motor) should be opened to lower amperage or closed to lower amperage? I have tried 3/4 HP Motor without success and have gone back to the stock size of 1/2 HP. So everything is back to where it should be but the thing still goes into a slow mode on high. I think its thermally shutting down... BUT every motor Ive tried does it.
And yes they were all new motors and were oiled and instructions followed. It is really puzzling me any HELP would be greatly appreciated

Thanks
Chris

How tight is your belt ?? The tighter the belt the higher the amps.

Is the wire to it the right size for that motor????

the pulley open will run the blower slower and use less amps
