Piston with rings GY6 4T 50cc 39,00mm

Piston with rings GY6 4T 50 cm³, for the engine, 39,00 mm in diameter. Four dimensions are marked in the photo, and if you're choosing, the first one is the cylinder bore.

• The piston with rings is replaced together with the cylinder, or after it is honed: once worn it loses its seal, compression drops, a rattle appears in a cold engine and oil consumption rises
• Marked in the photo: diameter 39 mm, from the crown to the pin axis 11 mm, overall height 34 mm, pin diameter 13 mm
• The maker did not mark the pin length in the photo — measure your own old pin
• The photo shows the set: piston, pin, five rings — one of them a toothed expander — and two circlips
• You will find just the rings for the same engine listed separately in the catalogue — "Piston ring set GY6 4T 50cc 39,00mm"
• The photo itself has no scale: no ruler, no object placed for comparison. Only the figures written in the captions give the size, so measure your own cylinder bore
• You will recognise a worn piston by a worn-out side, too large a gap in the rings and impressions pressed in at the pin bore; the rings are always replaced together with the piston

To be straight with you: which specific model and which years it is meant for, the maker did not write — write us your model and year. Before ordering, measure your cylinder bore and your old pin's diameter — or send us a photo with the callipers in it: we will check it before you order.
