Piston with rings 69,00mm

Piston with rings, 69,00 mm diameter. When choosing, the two numbers that matter most are the cylinder bore and the pin diameter – 17 mm.

• A piston with rings is replaced together with the cylinder or after it has been rebored: once worn, it loses its seal, compression drops, the cold engine develops a knock, and oil consumption rises
• The photo shows: 69 mm diameter, 16 mm from the crown to the pin axis, 49 mm overall height, 17 mm pin diameter, 55 mm pin length
• The photo shows the kit: the piston, the pin, five rings – one of them a toothed expander – and two circlips
• The photo itself has no scale reference: no ruler, no object placed for comparison. Only the numbers listed in the captions give the size, so measure your own cylinder bore
• If the piston is still sound but compression is dropping, rings alone may be enough: rings of the same 69,00 mm diameter are a separate item in the catalogue – "Piston rings 4T 69,00mm"
• You can recognise a worn piston by a scuffed side, too large a gap in the rings, and imprinted marks around the pin bore; the rings are always replaced together with the piston
• Supplier code MC 03719 – state it again when you reorder

To be straight with you: the maker did not write which specific model and year this is for, and we do not guess – write us your model and year. Before ordering, measure your own cylinder bore and the old pin diameter – or send us a photo with a caliper: we will check it before you order.
