oil all over magneto plate

broken oïl slinger part 10 on cd 13 list

If the oil slinger is broken, how do I access it to confirm and replace?

Thanks

Crosby, how did you arrive at that conclusion? Am I missing something?

In my humble opinion, that mess is excess grease from the mag plate mounting mixed and washed down by what ever leakage got past the slinger system. Let’s face it, the slinger system works surprisingly well, but it is not 100% effective. I always expect some oil on the mag plate after a lot of running. A proper cleaning and tune-up takes care of it.

Fleetwin, manifold vacuum is what sucks the oil back down to the crankcase. Those two "tube" sections between the screws in picture #1 are where the passages are drilled inside them.

Help me understand…
How can you tell that the metal crankshaft slinger is broken? Are you saying that stray piece in his hand is part of the slinger? It looks like some of the crankcase casting about the slinger might be missing, but not really sure just where the crankcase seam is because the mag plate is still in place.
Confused, as usual!

OK Frank, that makes sense, a messy lower seal assy would probably just supply water/rust to enter that area.

picture shows a ring in parts I had similar broken slinger on a 7.5

is the part not the slinger in the picture ?

Josh-
I think there is some confusion here, I don’t believe the slinger is broken. I would follow Frank’s advice and just clean everything up and reassemble.
In any event, the only way to access/replace that slinger is to split the crankcase and remove the slinger from the crankshaft.

thanks everyone! I got a flashlight and further inspected the oil slinger, and it looks to be perfectly intact. I cleaned all the grease and oil up from everything, and reassembled it. I just bought the timing fixture tool, and coil locating ring from Frank, so this is a great opportunity to break those new tools in. I’ll be tank testing it in the morning.

Thanks
Josh
