1975 Whip 400 Fan Blade

[thewhipguy]

Hey everyone, I am trying to replace the fan blade bearing in a 1975 Scorpion Whip 400, it looks like the fan shroud is casted into the bottom end of the engine, so I'm guessing I have to take off the cylinders to get at the stupid thing! There's gotta be an easier way to do this, can anyone shed some light here?
Here's some pictures of it.

Two real options. .

1) remove the mag side cylinder like you speculated.
2) remove the fan housing. There are 4 bolts under the flywheel that hold the fan housing to the crankcase.

If you have previously re-sealed the motor, i'd opt for removing the fan housing.

If you've never resealed the motor, now is the time to do it :-)

When you get to the fan bearings, you will find they are unsealed on the inside. We replace them with good high speed double sealed bearings.

Go here and click on fan / crankcase for a exploded breakdown.
