Hello guys,
since last week I'm the owner of an original 1946 Lister CS 12-2 engine.
The engine is in running condition but I hear a strange noise when I slowly turn the crankshaft by hand. It sounds like there's something loose inside the engine. I opened the crankcase door for a further investigation. After a short look inside the beast it was very clear for me, the governer gear wheel is loose on the camshaft! The taper pin which has to fix this gear is still in place but the 2 holes into the governer gear wheel are enlarged due to some reason. I have no idea how this could happen or maybe it's just normal after a lot of running hours (I don't know the historie of the engine). Does anybody else had a similar problem with his (original) CS twin-engine?
Anyway I've to repair it. At the moment I don't know how but first I've to remove the camshaft to be able to do a detailed investigation.
According the original Lister manual you have to remove the governer end flywheel before you can remove the camshaft. I've read on different locations that's not always easy to remove a flywheel. Does anybody know if it's really needed to remove that governer end flywheel to remove the camshaft? The engine has 6-spoke flywheels and there's maybe enough space between two spokes to pull out the camshaft. Any experience from CS twin owners?
I really hope that only the 'camshaft' bore of the cam gear wheel is worn out and not the camshaft itself. What about those Listeroid spare parts, is there a possibility to put such a camshaft in my engine?
Best Regards,
