Hi all
Just stripped a fully recon'ed by the local Lister specialists a Lister HR4 with very low hours ( maybe test hours no work?) which was smoking on two cylinders, the top piston ring on one had worn the chrome off the ring and I could see where the chrome had worn in a gap and was blowing through, all the other the top rings had worn the chrome also, the rest of the rings were perfect, the pistons and ring were the a /market brand AE normally a good product. I decided to fit a full set of genuine Lister rings, when deciding to hone the cylinders, on checking with a torch I found only one cylinder was normal ( but this had a worn chrome ring) shiny but no hone marks, one cylinder ( not a smoking one) was not bedded in at all, I could see all the hone marks from top to bottom very clear, the other two were half bedded in, non had any scuff marks or signs of seizing, non of the top rings that had the chrome worn off had large gaps (only 20 thou) and the gaps on all the other rings were normal , it didn't look a rough hone job , I gave it another hone and now they all look OK and the same,and will be fitting the genuine new rings, any comments on this would be welcome
Regards Barry
