We are getting into the realms of subjective rather than objective opinions, and how hard to hit something with a hammer is a prime example of that ! I can only suggest good old common sense and a small hammer. All this has been covered before in “Technicalities”, so I strongly advise you to have a good read of the various articles on this subject. End float needs to be around 12 to 15 thou”. The factory end float was 1/64″. It needs to be split evenly between the two halves of the engine. Lever the flywheel over fully to one side with a broad screwdriver between it and the back of the main bearing cup, and measure the clearance. Then lever the flywheel over the other way and measure the gap on the other side. The two measurements should be the same or within a couple of thou”. Again refer to “Technicalities” for more details.
