Piston YAMAHA JOG 70-47,00 SEE TW

Piston for a YAMAHA JOG 70 engine, 47,00 mm in diameter. The photo marks five dimensions, and the first two to use when choosing are the diameter and the pin bore.

• The piston is replaced together with the rings when the cylinder is replaced or after it has been reground: once worn, it loses its seal, compression drops, a knocking noise appears in a cold engine and oil consumption rises
• What "SEE TW" at the end of the name means, the maker did not write, and we do not guess — the same marking stands next to other items in this list
• The photo marks: diameter 47 mm, from the crown to the pin axis 21 mm, overall height 49 mm, pin diameter 10 mm, pin length 37 mm
• The photo shows a kit: piston, gudgeon pin, two compression rings, one thin ring and two circlips
• The photo itself has no scale reference: no ruler, no object placed for comparison. Only the numbers listed in the notes give the size, so measure your cylinder bore
• If the piston is still sound and only the compression is dropping, rings alone may be enough: rings of the same 47,00 mm diameter are in the catalogue — "Piston ring set GY6 4T 80cc 47,00mm" — but that is a set from the different GY6 4T line; whether it fits your engine, the maker did not write — write us your model, we will check
• You will recognise a worn piston by a rubbed-through side, too large a gap in the rings and imprinted marks around the gudgeon pin bore; the rings are always replaced together with the piston
• Supplier code MC 03491 — state it again when ordering

To be straight with you: which exact model and which years it fits, the maker did not write, and we do not guess — write us your model and year. Before ordering, measure your cylinder bore and the diameter of the old pin — or send a photo with callipers: we will check it before you order.
