Big oil loss on rear sid

[Werner]

Good evening and thanks to all!


What please are the advantages of using a bronze main bearing oil seal compared to the aluminum version?


My problem is that Mikes Shop doesn't ship (the bronze version) to the EU/Germany. I can currently still easily get the aluminum version from MACs and probably also from Don Snyder. -




I checked the crankcase breather; it's completely free and clean, without any sludge. -




Regarding my comment above about oil viscosity: The term "weight" is an American expression and has never been used in Germany. "Weight 60" essentially means "heavy oil," which generally means "thick." The correct term is the international SAE designation, which refers to the standardized viscosity grades.
"Weight 60" does not directly correspond to SAE 60.
