Original Lister Cs Engines / Re: Uh OH!

My experience with repairing cast iron has been good. Always braze! I've used a medium to low temperature brazing rod (Sifbronze K) with plenty of flux and never had a problem with distortion, cracking in other areas or lack of strength. There is no need to get the work piece super hot - medium red hot is plenty. If using a oxy acetylene torch remember Cast iron melts at a much lower temperature than steel.

Hi Scott,
Thanks for the info. The cylinder is genuine Lister I believe - no liner, just a solid lump and no evidence that the engine has ever been taken apart before. Your reply has put my mind at rest 'cos I can see myself taking the head and cylinder off and on at least twice to get the bump clearance right and I didn't want my workshop floor to be littered with new but un- reuseable head gaskets! Thanks once again.

Thanks Tom. One small concern; does this process mean I've wrecked a good new head gasket. Someone once told me that you can only torqu a head gasket down once. Will repeated removal and replacement make the seal iffy?

Many thanks for the info. Just so i understand what you're saying, does this clearance INCLUDE the head gasket thickness or is it a measurement of the piston top below the cylinder top face?

Rebuilding a newly aquired CS 6-1 after recovering it from an orange grove in Greece where it has been quietly rusting for about 40 years! It actuallly worked!! What is the bump clearance or deck height as some call it? My guess is that it should be set up with gaskets between cylinder and crank case so the piston is exacly level with the top of the cylinder, leaving the head gasket to provide the clearance. But I don't want to guess - hence this question
