gear-wheel-torque-limiter

Gear Wheel Torque Limiter: At the same time as the above was being 'beefed up' (2003), Husaberg changed the small idler wheel between the starter and the sprague assembly and created the 'gear wheel torque limiter'. It is designed to slip when faced with a massive surge such as a backfire etc and protect the starter motor. The assembly is built akin to an old drum brake with the friction surface on the inner wheel. The slippage value is between 7 - 15 lb/foot2. The gear was modified in 2004 to Part No: 21 800.40.021.100 04 GEAR WHEEL TORQUE LIMITER 04. The part can be disassembled and rebuilt with a larger shim: "The one I took off mine slipped at 5Nm, so when you undo the bolt that holds the two halves together there is a dished washer. All I did was to put a 0.015" shim in first then the dished washer, re-tighten the bolt and voila! it now slips at 25Nm!
