Worn 1.4″ idler changes belt wrap; stretched belt changes tooth mesh on the cog drive — replacing pulley + belt together​ (not belt alone) restores correct twin-blade timing. Test old: spin idler, any side play \u0026gt;1mm or gritty rumble = replace; belt teeth polished shiny = combo job.\u003c\/li\u003e\n\u003cli\u003eBolt to Rear Idler Bracket, Route 44″ Cog Belt, Torque to Manual Disconnect spark plug lead first, tip deck, photo belt path, relieve tension, remove 2 idler bolts, lift old pulleys + spacers, seat new pulleys with supplied washers in same stack order, hand-start, torque shoulder bolts to Toro manual (~40 N·m), loop 120-3335 cogged belt​ in original tooth orientation (don't flip inside-out), check rear idler alignment with straightedge against spindle pulleys, reconnect plug.
