Crankshaft GY6 4T 50cc

Crankshaft for a GY6 4T 50 cm³ engine – an assembled unit with the connecting rod pressed in. Whether it will fit into your crankcase at all depends on its length, diameters and end threads.

• Overall length 250 mm – dimension from the maker’s drawing
• The crank webs, that is the two round sides of the shaft, have a diameter of Ø 85 mm; the gap between them is 42 mm
• The end threads differ: M10 on the left, M12 on the right – worth checking before ordering
• On the left, Ø 16, Ø 23, Ø 35 and Ø 42 mm are marked, on the right — Ø 47, Ø 32, Ø 20 and Ø 15 mm
• A gear is fitted onto the shaft at the left end, marked Ø 23 mm in the drawing
• From the shaft axis to the lowered end of the connecting rod — 107 mm
• The same category has a GY6 4T 125 cm³ shaft — 300 mm long, with Ø 102 mm crank webs
• You will find the crankshaft’s Woodruff keys in the same category

We write only what we know. Which exact GY6 models this shaft is meant for, the maker did not state — the name only gives the engine type and capacity. Before ordering, measure the length, end diameters and threads of your old shaft, write us the engine model and year – we will check it before you order.
