Subject: Oil bath leaks

This is only for people keeping the chain and oil bath.

These are the places that the oil bath can leak and things that I have found wrong. 

(1)
At the oil seal- I have seen this seal in upside down. I've seen the secondary
shimmed to adjust the chain after the seal had been installed. Make sure it is glued
in.

(2)
The rubber seal between the top and bottom

I silicone both the front and rear covers. Make sure the pieces fit properly and that
the top and bottom are pulled together and clamped until the silicone dries.

(3)
The hole where the main shaft goes through
(A)   Try to keep the oil bath from hitting the seat back.
(B)   Keep the main shaft from touching the oil bath.
(C)   Have enough clearance on the front side of the main shaft to allow for chain adjustment.
If these things aren't ok, the oil can climb up out of the holes.

(4) The plexiglass cover
  
Seal the cover with silicone. Don't cut into the wood brace.

(5)
The seam between the two top pieces
Make the two pieces fit. Use silicone.

(6) 
Any holes drilled in the bath
When you drill a hole, it must be sealed. Use silicone
around the holes and also a little on the threads of the bolts.

(7)
Using more oil in the oil bath will cause the oil to leak out.

My helicopter is almost 5 years old now and hasn't leaked a drop of oil or anything
else. I don't consider myself a genius or even a good speller but if mine doesn't leak,
yours shouldn't either.

One more--- If you fly upside dowm, all the oil will leak out.
