Crank end play Options

[jmargush]

I am at the point of checking end play on the Crank.

When I first put the case together there was plenty of end play. Now there is not very much.

Is this normal as pistons and cylinders are added things tighten up?

when I push the flywheel in I set the dial indicator to 0 and then grab the fly wheel and pull it back.

I get a .006" while pulling but when I let go it settles at.005".

What is the correct measuring point under pressure or relaxed?

Should the flywheel just be pulled by hand or pried lightly with screw driver?

The crank shaft under load will move the maximum amoun that it can move.

You need to know how much it will move prior to putting shims in place.
003 is the goal.

You setup the dial indicator tap the flywheel towards the center of the engine with a rubber mallet, then zero out the gauge.

Hit the crank from the other side, fan end, to see how far it moves.
Use three shims to get the overall movement to 003

If you use more or less than three, they will get damaged.
