Sorry to learn that the belt problem on my Z122R is common. I wanted to find a replacement cheaper than the $80 the dealer wants, "none keep it in stock either" UMMMMM!!!!!!! Any buddy have a part number or a recommendation?
http://www.messicks.com/ku/93511?sectionid=235611&diagramid=523142 give these folks a try, have ordered from them several times, professional people & fast shipping. Belt part number is K3001-13560, price $35.64. Look under frequently used parts, you may have to sign in at no cost to you.
