I'm about to install the Mahle Euro (flat top) pistons and cylinders. I know that it is critical to have the pistons facing the correct direction relative to the flywheel. I'm used to seeing an arrow on top of the piston that is supposed to be pointed toward the flywheel. These Mahle pistons have no such marking.
This picture shows the top of the piston. Is that funny little symbol supposed to represent a crankshaft & flywheel? Is it critical which side faces the flywheel end or just that all the pistons are the same? I'm hoping someone answers quick - I'd love to get the heads on tonight! Attached image(s) |

Thanks guys...
Now, about deck height. I assembled the first piston with the thinnest barrel gasket. I measured the deck height using a straight edge and my feeler gauges. As I measure it, the deck height is .022". The only info I have on deck height is from Tom Wilson's book on overhauling air-cooled engines. This indicates a minimum height of .040" Do I need to increase the deck height by using a thicker gasket or are the specs different because of the non-stock pistons? |
