Lister CE endplay adjustment
mike90045:
With recording tape, it's called "stiction". In an engine, I'd look for oil that turned to grease. Odd, because once you got it moving, should be able to set an hour and still be free. Can you feel any play in the connecting rod ( upper or lower ) ?
something in the piston area seems to be the only large enough surface contact to "stick".
Maybe Felts on the bearings ?

The engine has 30 minutes of run time since complete reassembly, I am going to check to see if the crank is pinched between the cam gear, i can't remember if the crank had a seat to stop the cam gear from being driven on too far.

seems to me that the engine has to have some provision for thrust on the crankshaft, so that you could maintain end play to some spec called for
Mike makes a good point with checking the con rod for play, it should have some end play, where you can moved it back and forth on the crank journal, easy enough to check while you have the side cover off the engine.
anyone got a drawing of the innards of this engine model?

Mtour:
Thanks for all the replies..
I had to wet sand the sides of the rod bearing quite a bit to get them to fit the the crank, wet sanded them on glass until they would just move freely. Checked the rod bearings with platsicgauge, also tried to spin the crank with the rod bearings loosened to see if the crank would spin easier.
I have to try to get some endplay on the crankshaft, there is zero endplay on the engine now using a pry bar..
mobile_bob:
if you have no end play on the crank when it is cold, when it gets warmed up the crank will lengthen and you will have even more binding.
you mention having to sand down the sides of the con rod brg? to where it just fit?
i would continue to sand it down to where i had a couple thousands of clearance between the thrust sides of the brg and the cheek of the crankshaft. not sure what the proper spec is, but .002" would be ok in my thinking.
do the main brgs have the same thrust sides on them? at least on one end of the crank, there would not be on both ends, just on end i would think... otherwise there must be some other provision for keeping the crankshaft both centered and have some end play.... that is if the engine has plain brgs and not tapered roller brgs?
