The flywheels were OK if the operator followed the service manual and retorqued the flywheel with a torque wrench.
The trouble often started shortly after an engine rebuild or an end play adjustment.
Too little and she will shake loose. Too much and the bolt threads stretch and clamping power is lost.
By guess and by golley with a piece of pipe on the end of a breaker bar is sure trouble.
To use a torque wrench just weld up an off set from an old wrench and socket.
Any time when working on those flywheels toss the old fasteners away. New grade 8 bolts, hardened washers and tall grade 8 nuts. 275 -300 lb ft oil with cam assembly lube. Or 350-375lb ft clean and dry.
