Colin called with some good news saying the output shaft wonkyness was nothing more that the woodruff key fouling the flywheel keyway. However (there is always a however) that makes the overall runout worse as the flywheels were not parallel and were compensating for the output shaft so this means a new big end journal which will get the flywheels true. Also today I had the output shaft crack tested as when it had been recreated previously they had put no radius where the diameter changed so a potential fracture point, luckily all’s good.

Is “runout” another way of saying “wonkyness”?
Actually, the latter term puts me in mind of some sort of lacustrine monster!
