Exterior crankshaft seal and Bearing CD10

[Anonymous]

Trying to separate crankcase halves to replace pistons. All screws removed but must remove exterior crankshaft seal to allow splitting two halves.Suggestions please. Tks Jim aka boaters2

????What exterior crankshaft seal????

No crankshaft seal to remove. Did you remove the 2 screws behind the manifold/reed plate? See enclosed pic. These have to come out to split the crankcase.

Edit – you also need to remove the 2 taper pins. See pic. They drive out from the back toward the front of the case.

#10 & 11 on the schematic

Thanks will take a look. Likely not removed

#11 is the breaker cam that opens the points. It just slides off. It isn’t preventing opening the case anyhow.

#10 is a slinger, pressed onto the crankshaft. No need to ever remove it. It isn’t preventing splitting the case either.

The 2 taper pins (I Presume) in the previous answer, which direction are they removed? Towards the carburetor or towards the spark plugs? How are they removed? Thanks once again. Feeling dumber every day. My last rebuild was a ’58 Johnson 35 HP 10 years ago, that was a piece of cake compared to this CD10.

Toward the carburetor. Just knock them out with a hammer and punch. Your 35 had them too, if you remember.

What kind of cam is # 11? It’s stationary

Very difficult to get to, will keep trying. I’m not anonymous, Boaters2 , got completely deleted because I tried 2 many times to change my temp password to a new password. This process just kept going in a loop asking me over and over for my email addy. Now Boaters3
