Continental E-225-4 question
Gary wrote:
Jim, You're welcome. Sounds like the biggest hurdle, namely the prop, has already been taken care of. I'm guessing it is set up for constant speed with a Hartzell A-1B/C governor. If so you should already have a tee drive on the LH side in tandem with the fuel pump, either a Romec RD7790 or a Thompson TF1900. If you have the Thompson watch out for the drive pin which should be inspected periodically for wear. When they finally go the engine gets very quiet :^). The bottom ends on these engines are pretty tough. If you have good oil pressure (e.g. 40-50psi hot cruise, 10-15psi hot idle) then it should make TBO and perhaps beyond.

I should have included that in my original post. Other than that, I surmise from your post that... 1) shortage of accessory drives may be a problem, 2) the starter will be expensive to repair, 3) the generator may be insufficient if I need more current draw than 35 Amps, 4) it will need to be topped in another 400 hours or so (but then it will probably be run out also won't it? 1800 SMOH) 5) low power, rich of peak will be best for longer term operation. This is currently in an aircraft that doesn't have too much else at risk, so the engine seems to be my biggest concern right now. Vref is showing $26,000 for a major on an IO-470 so I'm taking that into account. Thanks for the thoughtful reply. -- Jim Carter Rogers, Arkansas"Gary" wrote in message I know Gary.
