2 x M5x16 Bolts for Alternator Fastening – For SPY Racing Quad SPY250F1/F3 (Zongshen ZS172FMM Engine)
The alternator (stator) is a central component in the engine, and its fastening is exposed to extreme vibrations and thermal loads. A loose or missing bolt can lead to alternator bearing damage, imbalance, and in the worst case, the failure of the power supply.
This set of two original replacement bolts (M5x16) ensures the secure and firm mounting of your alternator in the crankcase. They are specifically designed for the thread specifications of the powerful Zongshen ZS172FMM engine (Note: also fits ZS166FMM engines) and correspond to the manufacturer number 100011169-0004.

Original Specification: Exactly matching the length, thread (M5), and pitch for the Zongshen engine.

Cleanliness: The threaded holes must be clean and grease-free before screwing in the bolts.
