'Brad,
We have two oil filter versions approved via FAA 337 for the Ranger install.
Airwolf spin-on and ADC Disc type. Both are remote systems. Ed did the
Airwolf and is installed. I did the ADC Disc type and has not been
installed. FAA engineneered approved only. I use the ADC on the Stinsons. I
like the Disc type, avoids the cutting and purchase of the filters. Also
provides additional cooling since the filter housing is finned. Both systems
offer Oil by-pass mode and Metal detection sensors.
As for the Piston mod. You can get with Ed W. or Tom Goodlett. Brad, Tom is
in Texas, tool is in the Auto restoration shop, right side walking in. He
developed the tooling for Ed years ago. There are only two sets of tooling
that we know of. Very simple, but has to be accurate. This mod is a knock
off of the Warner piston setup.
As for Air-Oil separators. I have not found any large enough units state
side to apply. There are some nice pint size ones, to small for Ranger
operation. Bob Haas in Fla just purchased one from Germany. About a 1qt
size. Wes Allen (Tom Goodletts 24R46A) has a nice unit installed, works
well. I have no drawings as of yet for a Air-Oil Sep. Go take a look at that
one. Simple design.
Standard Ranger Oil consumption is between 1 to 1 1/2 qt per hour at 2150
RPM. If you choose to run it at 2250 or higher, you will double oil
consumption. Normal fuel per hour is 10gal per hour. I have seen 8.9 gph at
13,000msl and leaned. I always plan for 10gph per hour. This past summer I
ran the Ranger at 2350 with the Aeromatic for 1 hour. Used 21gph and three
qts. I was bored on a commerical flight a few months ago, had the UC61A flt
manual and did some fuel burn calculations. A Ranger full military power
(2450 - 2500) will burn 33.5 gallons per hour. Suck those tanks dry in under
two hours. Nice to know if you have to push it someday. You will be out of
gas before oil. I had to run the Ranger hard last summer coming back from
the Rocky Mountain Fly-in to beat bopping thunderheads. Ran it for 45 min
full throttle, 2350 rpm at this alt with Aeromatic. It does suck the fuel
and blows out the oil.
Best plan for engine life. Remote oil Filter install, Remote oil heater
behind Oil tank for cold weather, and a light weight Pre-oiler. Also
provides a eng oil pump backup for remote operatings at night and mountain
flying. I will be installing all of these in three aircraft, 1934 Waco Cabin
YKC, 24W40 and my 24R46 when restored. There is only one pre-oiler that I
found that is FAA/PMA approved, very expensive($1,600), heavy and space
taking. I found another one in Calif, made by an aerospace company, lighter,
and fraction the cost. I will be using this one for all the aircraft above
useing a FAA 337. Here is the company info below. Also attached the info.
Slick little unit. All engines should have, even my autos.
