Hoping to get some feedback from others who have this mower deck, or have encountered a similar situation...the belt on my ZG227 mower, (deck model RCK54P-227Z) slaps quite a bit as it comes off of the pulley on the right side as it goes on the long run to the left side pulley (approx 3ft straight run of the belt from one pulley to the other). I initially suspected a bent spindle or pulley, but couldn't see a bend when I removed the spindle and pulley. Replaced the spindle anyways, but the result is still the same. When rotating the pulley with the belt removed, there is a slight "out of round" rotation, approximately 1-2mm where the rotation of the pulley versus a fixed point on the deck doesn't stay perfectly circular. Aside from causing premature wear to the belt, it's also causing the belt to rub various guide posts, as well as a nut that secures the mower gearbox to the deck.
First question I have is, how much belt slap/movement is expected and acceptable?
Second question is, what else could be causing the rotation to be slightly out of round, if the spindle and pulley are good, and the bearings appear smooth and operating normally?
Note: the out of round condition is also present on the left side pulley, but the belt doesn't travel as far to the center pulley as it leaves the left pulley, so the belt slap isn't as noticeable.
Thanks
