Section 7.
Oil Bath and Engine Accessories
UPDATED!!!
This section is finally completed!
This is the countershaft for the fan. The reason for this type of drive system for the fan, even though it is mounted to the secondary unit, is so that in autorotation, the only things using stored energy are the mainrotor blades and the tailrotor blades. The fan is mounted to the shaft, via bearing, which is secured with loctite.It sounds a little complicated, but it works.

Here are the alternator and waterpump. It took a little bit of patience to get everything where it was happy.
This shows the idler arm and pully engaged with the drive belts. You also see the lower oilbath is starting to come together.
Another shot of the idler pulley engaged. This is taken from the bottom looking up. You will now start to notice little orange stripes on nuts and bolts. At least they are supposed to look like stripes. Some of them resemble blobs but I'm getting better at this stuff now. This is called torque seal. It is there to show any signs of movement or loosening of hardware. If something were to twist or turn, it will flake off or show signs of movement.

Looking from the rear.
From the top you can just see the clutch arm and the end of the clutch piston tube. Here I am just getting ready to install the rear seal over the secondary shaft.
This shows the main sprocket bolts final installed and wired together.
Notice the safety spacer is now on the mainshaft.
With the lid on and window siliconed in place. I also put a visible mark on the sprocket at the index mark on the secondary shaft for preflight inspections.
This is a little easier to see. The master link clip is also painted for ease of identifying.
