Just as with the ground drive belt this deck belt a PIA for me. It is in and works well, but (surprise) the owners manual instruction of 3/8 breaker bar to relieve idler pulley tension did not work (for me). The new oem belt is very stiff and with deck in lowered position some slack is lost. A second set of hands might help or overnite stretching . Even a 1/2 breaker with pipe extension did not allow final pulley engagement. Finally , installed belt with no spring , loosened spring-coupled tension bolt down to last 5 threads in locking nut , fished through its hole, then used a heavy gage wire hook to pull the spring onto the banjo portion of special bolt. Then the nut is tightened to its original position, in this case .887" of exposed threads. A fix would be find a similar grade 5 bolt with enough threads to extend the adjustment another 1/2." This would call for drillling this new bolt head or its shaft with a hole to accommodate the spring hook diameter or to ? weld? This "simple" belt task probably defeats many owners.
