I have a 92908 series cylinder which has been resleeved with cast iron sleeve. I see in the parts list there are 2x part no's for std rings - 298982 (cast iron type?) & 299742 for chrome rings. Which should i use for a cast iron sleeve?
You can use either cast iron or chromed rings in a cast iron bore. If they are properly designed and made, the chromed ones are likely to last considerably longer.
