Cylinder with piston YAMAHA AM6 40mm TW

YAMAHA AM6 cylinder with piston, 40 mm. In the box – the cylinder, the piston, the pin, circlips, rings, a large red sealing ring and a base gasket.

• The set includes, visibly: the cylinder, the piston, the gudgeon pin, two pin circlips with a few small rubber rings, two piston rings, a large red sealing ring and a green base gasket
• The body is smooth, with no cooling fins, and the set includes a coolant sealing ring – this is a liquid-cooled engine cylinder
• The manufacturer's drawing marks: 52 mm between the upper mounting holes, 40 mm and 25 mm at the base; the piston pin is 33 mm long
• The drawing also has 12 mm, but what it measures the manufacturer did not say, so we do not assign it a meaning
• The cylinder bore is not marked in the drawing – the 40 mm is taken from the name
• Wear is visible to the naked eye: longitudinal scratches on the cylinder wall, a polished piston skirt, and a ring that rocks freely in its groove – then the whole group is replaced at once
• No gaskets, apart from the red sealing ring, are visible in the set; for the same AM6 engine the list has "Engine gasket set MINARELLI AM6 head-cylinder B"

To be straight with you. Which specific models and years this cylinder is for, the manufacturer did not say, and we do not guess – write us your machine or send us a photo of the old part. Before ordering, remove the spark plug and use a calliper to measure the old cylinder's bore, the pin thickness and the distance between the studs – we will check it before you order.
