Just found and joined this group. Sure hope someone can help me out here. Husband is trying to replace broken Pump Drive Belt on our Scag Wildcat 52" mower. He can get it on the mower but it is too tight to attach the idler pulley. I have done extensive searches on the web and can not find any resource to help resolve the problem. Have confirmed we have the correct belt (part #482531) via Scag. It was purchased from a Scag Dealership. Is there some "trick" to getting the belt on for a proper fit. Any help or suggestions would be GREATLY appreciated. Thank you in advance for any help you can provide.
