Cylinder with piston YAMAHA JOG 50cc 40mm TW

YAMAHA JOG 50 cm³ cylinder with piston, bore 40 mm. The box contains: cylinder, piston, gudgeon pin, circlip, rings and two gaskets.

• The set shows: a black finned cylinder, a piston, a piston pin, a pin circlip, two brownish rings with a thin band, a metal head gasket and a yellowish paper base gasket
• The body has cooling fins and no hose fitting — it is air-cooled
• The maker's drawing marks the cylinder bore as 40 mm — the same figure as in the name; the top face is 50 mm
• The piston pin is Ø 10 mm and 33 mm long
• The catalogue also has a YAMAHA JOG 50 40 mm cylinder with no drawing and a green base gasket, and a JOG 60 cm³ version with a 44 mm bore
• Wear is visible to the naked eye: longitudinal scratches on the cylinder wall, a polished piston skirt, and a ring that rocks loosely in its groove — in that case the whole set is replaced at once
• Supplier code MC 04721M20-CY004 — quote it again when ordering

To be straight with you: which exact models and years this cylinder is made for, the maker did not state, and we do not guess — write us your machine or send a photo of the old part. Before ordering, remove the spark plug and use a caliper to measure your old cylinder's bore, the pin thickness and the distance between the studs — we will check it before you order.
