Piston rings 4T 63,25mm

4T piston rings, 63,25 mm in diameter. The number is taken from the name.

• Piston rings seal the combustion chamber and scrape the oil off the cylinder wall; worn, they let pressure through – compression drops, oil consumption grows and blue smoke comes from the exhaust
• The diameter is taken from the name: there is no number on the rings themselves or in the photo
• The photo shows five rings: two compression rings, a copper-coloured spring expander and two thin oil scraper rails – that is the composition of a 4T engine set
• In this card the photo is shared by eight cards from the same list – from 62,00 mm to 63,75 mm – so we do not judge the diameter from it, and we do not describe the appearance based on it
• The same line progresses in 0,25 mm steps; next to it in the list are "Piston rings 4T 63,00mm" and "Piston rings 4T 63,50mm"
• Rings on their own are needed when the piston is still sound – there is no piston of the same 63,25 mm diameter in the list; the nearest are 63,00 and 63,50 mm – "Piston with rings 63,00mm" and "Piston with rings 63,50mm"
• You will recognise a worn ring by too large a gap at the joint, and by the fact that it falls freely inside the cylinder; all the rings in the set are replaced at once, not one at a time

To be straight with you: which specific model and year they are for, the maker did not write, and we do not guess – write us your model and year. Before ordering, measure your cylinder bore and the height of the old ring – or send a photo with calipers in it: we will check it before you order.
