spinning but the engine isn't engaging, nine times out of ten it's the drive unit's freewheel slipping, not the starter motor.

slipping or misaligned, it has often also damaged the ring gear: check it before reassembling, otherwise the new part will wear out in a few weeks.\u003cbr\u003e\n    • \u003cstrong\u003eBushings,

If you hear the starter motor spinning freely, quickly, and without effort, it means it's not engaging anything: the freewheel inside the drive unit is slipping, and the motion isn't reaching the flywheel. This is the most common cause, and it costs a fraction of a new starter motor.\u003c\/p\u003e\n\n\n  \u003cp style=\"font-size:15px;\"\u003e\u003cstrong\u003eWhat's the difference between this and the starter motor?\u003c\/strong\u003e\u003cbr\u003e\n  The starter motor is the electric motor; this is the gear in between that transfers movement to the flywheel ring gear. They are two different spare parts, with different codes. Before ordering the starter motor, it's always advisable to rule out the drive unit.\u003c\/p\u003e\n\n\n  \u003cp style=\"font-size:15px;\"\u003e\u003cstrong\u003eWhat does the supply include?\u003c\/strong\u003e\u003cbr\u003e\n  The complete and assembled drive unit, as in the photos: crown, pinion, shaft, and freewheel. It does not include bushings, O-rings, oil seals, or the crankcase closing screws: these should be reused if intact or ordered separately.\u003c\/p\u003e\n\n\n  \u003cp style=\"font-size:15px;\"\u003e\u003cstrong\u003eShould I check anything else while I'm in there?\u003c\/strong\u003e\u003cbr\u003e\n  Yes: check the teeth of the flywheel ring gear. If the drive unit has been slipping or misaligned, it has often also damaged those teeth, and a new part engaging with a damaged ring gear will not last long.\u003c\/p\u003e\n\n\n  \u003cp style=\"font-size:15px;\"\u003e\u003cstrong\u003eDoes it work for both 4T and 2T Purejet engines?\u003c\/strong\u003e\u003cbr\u003e\n  Yes, the catalog provides this code for both 50 4T and 50 2T Purejet injection engines – NRG Power, Runner Pure Jet, and Aprilia SR and RS.
