HELP!--I keep throwing belts---I had this problem last year too-----I run an alternator & ps. on a hobby stock-----the first time out I threw the PS belt which in turn took out the alternato belt--one of the two grooves on the ps. was not in line with its counter parts,I solved that problem I went to the other groove and the belt stayed on the next time out. But then I threw the alt. belt on the second time out.
Over the winter I replaced all the pulleys with a match set off of another engine from a street car Keep in mind that I run IMCA hobby stock so I dont have many options when it comes to pulleys. When I idle the car up to about 4 k rpm's and higher the alternator belt starts dancing between the crank pulley and the alternator.I maybe answering my own problem here, but I've noticed that the waterpump pulleys have a little run out (not a whole lot) as you spin it with out belts no matter which set of pulleys are on it. Could this be the problem,could the mounting surface on the water pump its self be warped enough to throw the belts in a higher rpm situation??
ps.Don't tell me to loose the alternator-it's not happening
