Hi Marc,
First of all, this is the gearbox on the 540ci V8 I've been working on (forever... 8-( )... I haven't a clue who made the gearbox itself, but it uses helicopter technology, has a prime number of teeth on all gears, no mesh less than 2 teeth at any time, etc. It's a big honker, has to weigh 100#. The pic of the left side shows the oil filter and just above it you'll notice a little circle... that's a sight glass. The oil level is to the middle of that glass. The oil line just to the right of it is the return from the cooler. The line coming out from just below the filter is the pressure line to the cooler. There is no oil reservoir, pe se, but the cooler and its hoses hold about another quart beyond what it takes to fill the box. The part sticking out in front of the filter (you can see it just aft of the hoses that wrap around the front) is the pump section. (I originally thought that the gears were splash lubricated, but that's not the case and is another reason it has an oil pump (along with feeding the governor.) You can see the McCauley governor kind of at the rear, in line with the prop shaft. If you look at the pic of the right side you'll see the starter... it's just a teeny thing but does a great job. The only reason I mentioned all this was because you were talking about building a box with c/s capability and this one has it, so I thought you'd be interested.

Who makes this gearbox, and how much does this baby weigh? Does it have
its own oil reservoir? I understand this set up is what the Marcotte
unit needs as well.......

The gearbox on the Eagle540 has its own oil pump / filter / cooler and
the
[McCauley] prop governor is mounted directly to it. It uses its own oil
supply
(designed for gears instead of engines) to spray-lubricate the gears and
its
pump provides clean, cooled oil to the prop governor for its final
pressure
boost. One nice thing about having a closed lubrication system for the
gearbox is that you can use oil which is optimized for that purpose, and
tracking its separate oil pressure and temperature provides some warm
fuzzies
re the condition of the gear box. Just thought I'd share the data
point.

Hi Ed,
No, this will utilize the typical oil driven type cs prop governors
found on 99% of aircraft now. It will be fed and will supply oil to
the
prop hub just like most typical cs props-just like Mistral's unit and
the Marcotte unit (but much more economical, if we can pull it off). I
want to use a Whirlwind type prop-they use Hartzell type cs hubs. It
will have a typical SAE cs type prop flange. Use any cs prop. It is
based on a planetary reduction in production for other uses
(helicopters) in Eastern Europe.
