*HighRpmRacer Special Socket - Spanner Tool - GY6 150cc VIEW ALL SHOP TOOLS HighRpmRacer Special Socket for removing the 4 notched nut holding on the starter clutch on the GY6 150cc engine. This nut looks like a pesky little clutch nut used on the 110cc and under engines, BUT is larger style nut. Also the nut used on the GY6 is reverse threads and removes in the clockwise direction. This socket makes short work of removing the nut and is a MUST-HAVE for the shops performing work on scooter style engines. The crankshaft extends past this nut requiring a deep well type socket and this tool is the deep well style. |
