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) |

Things like flycutting the head can change figures in a hurry and I state "about 60cc", as this size was never a constant right from the factory...I'd say that size +/- 2 or 3cc (more often +).
I know Dave Hunt made up his own head cc plate, maybe if you asked him nice he would make you one or let you borrow it. Or most bug shops carry 94mm Type1 plates and the head cc kit is about $20. You can also use the plate to get your dish cc, it's not very big on a euro, somthing like .5 to 1cc. |
