Paul / all


To make a 20B mount I need the dimensions of the oil pan mounting hole
positions and I was hoping I could get this from this rotary list.
Would be much appreciated. Also, the locations of the holes in the
windage tray. I need to know if there needs to be a CG shift forward
from the 13B position?


Also, does the 20B use the same water pump cartridge as the 13B?

Cozy soon 20b?

I don't have those dimensions but if you use a 1/8th thick sheet of Lexan
and place it where the pan goes you can center punch the hole positions.

The need for a windage tray is over rated. The locations are mainly
a function of the parts such as the pressure regulator and the oil
pick up tube that must pook through them.

I'd sure be interested in talking to you about fabricating the mount. I
have lost a fortune on Fred Breese and need to get my project back on
track. Since I will get nothing from Conversion Concepts for all my
money and a year now, I need to pursue alternate sources.  I have
mounting plates but need the truss structure.

Send me the hard point locations, an outline of the firewall, the thrust
line position and the length from the firewall to the prop flange.
