weathered 582 maintenance.
in 2 Stroke Technical Questions
10 years ago
Hi all, I bought a chinook plus 2 that was built between 2002-2005. The build was never finished. In 2005, the plane was brought to a local airport and left outside in our canadian weather until spring 2014. All ports and holes had been sealed and the engine was mounted inverted. It is a blue head 582. Because the build was never finished, the engine had never been broken in. Actually, it had never seen gas. I took the head off and looked at the cylinder and pistons. They looked absolutely brand new. I also took a boroscope through the carb ports to have a look at the crankcase and crankshaft. Everything looked brand new and i couldnt see any corosion. All parts were still smeared in the rotax factory grease. When i took the plugs out, only a bit of oil came out. I was told that because the engine had never seen heat, the factory corosion protection did the job for 9 years. Now, I got the engine back on the plane, cleaned the carbs and she fired right up.
With the extensive experience on this site, would anybody have concerns with this old/new engine, any parts that they would replace unconditionally based on the 9 years. Aside from a bit of surface rust on the gearbox plate, i could not find any corosion. The engine still looks new.
it is now sitting at 1.3 hours after the break-in and aside from poor liquid cooling during static runs (it gets to 180f in about 20 min then i have to bring it back down to 2000-3000 for a few minutes to cool it down) EGT's are around 930-1050 through the range and the CHT's sit around 250-300f. It has the E gearbox at 2.62:1 and a GSC 3-blades 68" ground ajustable prop.
i will need to retorque the head and exhaust manifold.... what else would you check, replace?
The prop was never mounted until 3 weeks ago.
please voice any concerns you would have with that engine or anything else. I am new to ultralights and DC rotax's.
