Bought my Scag ~5 years ago and have keeping up on my maintenance and I have a question regarding my pump drive belt. I was experiencing a bad vibration throughout my mower a few weeks ago so, I replaced the following items as it was time to replace anyway:
1) Deck idler pulley, deck tensioner spring, tensioner pulley, and both pivot bearing (both were smoked) and cutter deck drive belt 2.) Pump drive belt, tension spring, idler pulley, both pivot bearings, and a new belt 3.)Lastly the deck drive belt, tensioner spring, both pivot bearings, and the idler pulley on it as well. My spindles are in good shape so the vibration isn't coming from there either. When I start the mower the pump drive tensioner shakes like a leaf on a tree. My dad has an 07 STT 61V and has almost no vibration present. The only visible difference between mine and his is mine has a traditional V belt (482641) and his has a cog belt (both sourced from Scag). I'm thinking my alignment may be off or, is there something I am overlooking? When I bought the new spring for the pump drive tensioner, it came with a spacer that I installed. My previous spring did not have this. Going to eliminate it today as a variable. Am I over analyzing this/???
Thanks,
