Crank shaft bearing sizes for D6 pony motor. It’s an opposed cylinder twin.
I’m looking for journal sizes.
Also looking for recommendations for a source for replacement bearings and piston rings.
The crank has spun one rod bearing. The good journal measures out at 1.875” and the spun journal is 1.870x1.850/oval.
What’s the largest oversized bearing that are available for the rods on these? I’m assuming the standard size is 1.875 since I could not find any oversized marking on the old bearing shells.
An .030 cut should clean this crank up as long as I can get .030 bearings.
Thanks in advance.
