Piston rings 4T 63,50mm

Piston rings 4T, 63.50 mm — the size comes from the name alone. A five-ring set: two compression rings, a spring expander and two oil scrapers.

• Piston rings seal the combustion chamber and wipe the oil off the cylinder wall; worn, they let the pressure past — compression drops, oil consumption rises and bluish smoke comes out of the silencer
• The diameter is taken from the name: there is no figure at all, either on the rings themselves or on the photo
• Five rings in the photo: two compression rings, a copper-coloured spring expander and two very thin oil scrapers — that is what a 4T engine set is made of
• This photo is shared by eight products in the same category — from 62.00 mm to 63.75 mm — so we do not judge the diameter from it and do not describe the look by it
• The same range goes in steps of 0.25 mm; the neighbours in the category are "Rings 4T 63.25mm" and "Rings 4T 63.75mm"
• A piston of the same diameter is in the category — "Piston with rings 63.50mm"
• Rings on their own are what you need when the piston is still sound — if it is worn too, take the piston with rings: it is sold with the same rings in one set
• You will know a worn ring by too big a gap at the joint and by the way it drops freely in the cylinder; all the rings of a set are changed at once, not one at a time

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