Flywheel orientation

[Truckedup]

 I removed the flywheel for crankshaft machine work .Made a punch mark on the wheel and crank before disassembly. It's possible it was incorrect before  I got it, bitsa engine.
 So now when assembled it doesn't look corrrect... Are there factory makings to show which side goes where?  Thanks

G'day Trucky.
Easiest way is to have the heaviest side of the flywheel opposite the rank pins.
Cheers

Yes, heavy part of flywheel 180 degree from the crank pins.....But you can install with this side or the other side up...No problem as the bolts only line up one way....So my punch marks were correct....A big worry over nothing....
