Piston with rings 56,50mm 15mm pin

Piston with rings, 56,50 mm diameter in the name, 15 mm pin. When choosing, what matters most is that the numbers in the name and in the drawing differ.

• 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 name says 56,50 mm, while the photo shows 56,4 mm – this is not rounding, it is a different number; we do not hide the difference and we do not pick a side
• The catalogue has a separate item "Piston with rings 56,40 pin15mm", so 56,40 here belongs to a different size
• The photo shows: 16 mm from the crown to the pin axis, 49 mm overall height, 15 mm pin diameter, 47 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 – but there is no separate 56,50 mm rings in the catalogue; write us your model and cylinder bore and we will tell you what we have
• 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

To be straight with you: 56,50 mm in the name and 56,4 mm in the drawing – which one is correct, the maker did not explain; we are asking them. 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.
