Lister L information

[KidDynamo]

My steady progress towards firing up my Lister Spec. 82L 6 hp @ 500 rpm engine remains on course. I've decided my gears are good and my engine noises are emanating from the valve lifters (cam followers) as they are lowering. There is quite a large lash gap and I am wondering what the valve lash adjustment should be and how they are to be set- hot/cold?...running/stopped?....

Of course I am hoping that Peter, alias Listerdiesel, will see this and have the info but if anyone else has any info on this type of engine, please add!

I encourage anyone who has a chance to get one of the English engines to jump on it! Just preserve all your hardware because the thread sizes are not readily available at your local hardware store. My questions at the hardware store generate, at best, a glassy eyed stare. LOL

Thanks, as always!!

The old book I have quotes 1/64" or 0.016" for the inlet and 1/32" or 0.031" for the exhaust. Those figures seem to be common to most of the early large petrol engines, as it is quoted for the 'N' and 'R' engines as well, in a separate book. The setting is cold with the engine stopped.

Make sure that the face of the cam follower isn't indented, as that won't be allowed for if you use a standard feeler gauge. Always stone the face flat if it has anything like a decent depth of indentation in the top face.

Whitworth and BSW threaded nuts and bolts are still freely available over here, so if you get stuck, give us a shout and we will sort something out for you. Note that Whitworth hex sizes are different than BSW, although the thread is the same.

BSW (British Standard Whitworth) was introduced in WWII to economise on steel usage, and for a given thread size the hexagon is smaller than the original Whitworth sizes.

In an emergency, UNC can be substituted for Whitworth or BSW.
