Bearing Adjustment With Counterweighted Crank

[1928 Briggs 60A]

I've heard that you can't adjust the rear main bearing clearance on a Model A with a counterweighted crank with the engine in the car. Is this true?

It depends on the shape of the counterweight. With some you can, some you can't. If you can, it's usually tight. During the assembly with the engine on the stand you can notch the flywheel housing to clear the main cap.
