Lycoming Engine Break-In
I advanced searched on here and the latest thread is 2009.
Ly-Con said to break-in my Lycoming per Service Instruction 1427C. Item 1 says: Do the engine pre-oil in accordance with the latest revision of SI 1241. I can NOT find SI 1241 on Lycoming's website? Does anyone have this SI?
Also, under the flight test:
1. Do a preflight run-up IAW the POH.
2. Do a full power take-off IAW the POH.
3. Monitor eng RPM, fuel flow, oil press, oil temp, and cylinder head temp.
4. As soon as possible, decrease eng speed to climb power IAW POH???? Really, I thought you had to run it hard?
Also, 7 states to decrease power to approx 75% at cruise altitude for 2 hours. So is that .75 X 2700=2025? That does not seem hard enough. I use to cruise around at 2350 prior to sending this engine to Ly-Con???? What are all you experienced guys doing? I kept it a 150HP with new Lycoming cylinders.
Thank you,
Brett
