Eugene, The fellow who replaced the transmission and the belt inspected his work and determined that he had put the new belt on the wrong side of the belt guide. He fixed that problem and the mower works as it should.
Eugene, Well the Husqvarna dealer said the part number I was sold is the correct part number but he couldn't be sure I actually got the right belt unless he looked at it. He did suggest that because the belt is new it was most likely tight and that that could cause my problem. He suggested I adjust the cable, which I had already done. He also suggested that the belt might be installed incorrectly on the pulley. He did not have a schematic of how the belt should look installed - only the parts diagram that io already have. Next step is to ask my mechanic friend to revisit the work done. Tim
Eugene, the part number on the receipt from the dealer is 532406557 which is the number on the parts list i printed in 2014. I'll let you know what the dealer says after my visit today. Thanks again. Tim
Eugene, thanks for the response. I bought the part at an authorized Husqvarna dealer. I actually gave the dealer the part number from the mower's parts list.A friend who is experienced with mower repairs installed it for me (a hassle for sure). I'll double check with the dealer to be sure I was sold the correct belt. Tim
