Oh Dear,
Just when things were going OK - I had rings compressed with new ring compressors (photo attached), had the cylinders dropped on, and was removing the ring compressors when one of the trunnion pins fell out and into the crankcase.
What a sh--t design.!! - how could a maker not see that happening.?? I had assumed that the trunnion pin could not slide out.
It is about 1/4" diameter x 3/4" long. I cannot see it and suspect it lies beneath the flywheels somewhere.
AND I had the gasket sealer on ready.!!
I had removed the rags to make it easier - and now much harder.
As a first step I will remove the sump plate and try to wash it out or use compressed air to dislodge it.
Anybody had any luck without dismantling the engine?
