1940 buick flywheel position

[papafarms]

Hi guys, hope all are enjoying this nice spring weather, to the point, is there a position that the flywheel goes or is it universal positioning when setting up the timing, in process of rebuilding engine, mark was made on flywheel, but seems to have disappeared on block or where ever the other mark should have been, any help would be greatly appreciated, my buick is a special 40 series , engine a 248, thanks bob in maryland

This is a real trap for young players as they say.

The flywheel is "not" dowelled or drilled in a staggered pattern to make sure that it will only go on in the correct position.

It can, and regularly does, get put back on with the timing mark in the wrong position.

If you don't put it in the correct position you'll never find the mark when you start the engine.

You need to check that the timing mark is visible in the timing mark window on the flywheel housing when the No1 (front) piston is at top dead centre.

The flywheel is used to balance the crankshaft. Misalignment can destroy crankbearings. Don't recommend running it unless your sure of proper alignment
