I took the engine out of my '34 tourer in order to sort out the horrendous oil leaks, and to check it because it came with the car with no history.
With the crank in its bearings in the crankcase, flywheel on, the was a very small but perceptible movement in the rear main. What I would expect, I think.
On spinning the crank, there was a recurring noise on every revolution. A heavy "click" or a light "clunk".
So I have pulled the rear main outer out. There is no perceptible roughness or end float in the front mains.
On spinning the crank, the rear end has a pronounced wobble, which I guess was producing the noise inside the rear main, as the inner moved from side to side in the outer.
This must impose a bending movement on the crank. It cannot be good, but is it normal?
Crank and case are marked 191580, it isn't the original engine, but isn't far off it, and is the correct rubber mounted high frame crankcase.
Any thoughts welcome.
Thanks
Simon
