Read Continental's stuff on compression testing/reading. The numbers aren't everything, they ran an engine with compressions in the 40s on a dyno and found no loss of power. . COMPRESSION TESTING OF AIRCRAFT ENGINE CYLINDERS. A test to determine the internal condition of the com- bustion chamber cylinder assembly by ascer- taining if any . The differential compression check has been a mainstay of piston aircraft engine maintenance for 80 years. Like anything else in aviation that’s been around for a long time, various old wives’ tales have evolved about the . Although unacceptable to Continental, it is quite common in the field. The classic tool and traditional guidelines work fine for an owner who wishes to monitor trends for a specific engine using the same tester each time—particularly if the test values are well above 60/80. Remember, minimum values determined with a master orifice are in the 40s.
Find faulty cylinders quickly. Static test your Rotax 912 cylinder compression with 80 psi shop air. No cranking required. Just find TDC and pressurize cylinder to 80 psi. Left gauge allows you to regulate pressure with built-in regulator valve. Simply adjust pressure and slowly open built-in petcock and read differential compression.Engine Test Kit Ek5Em The ATS Engine Test Kit has all of the test equipment needed to check engine compression, synchronize magnetos, time aircraft engines, and test ignition leads all in one tool box. The complete kit contains our 2EM Diff
Finally, Continental says that if a cylinder exhibits a compression reading below the no-go threshold but the borescope inspection reveals no obvious cause for the low compression, the aircraft should be flown for at least 45 minutes and then the cylinder in question should be re-tested hot. If you do that, you'll find that Continental says that the minimum acceptable compression reading is to be established using a "master-orifice tool" hooked up to the mechanic's compression test gauges. For most compression test gauges we've checked, the master-orifice tool sets the no-go limit between 41/80 and 43/80. However, each gauge is .with the engine under static conditions (not running), using a regulated pressure source. When performing a cylinder differential pressure test a regulated test pressure of eighty pounds per square inch (80 PSI) is directed into the cylinder with the piston at top dead center at the end of the compression stroke and the beginning of the power .with the engine under static conditions (not running), using a regulated pressure source. When performing a cylinder differential pressure test a regulated test pressure of eighty pounds per square inch (80 PSI) is directed into the cylinder with the piston at top dead center at the end of the compression stroke and the beginning of the power .

Aircraft Engines. Piston Engine Maintenance . In addition, for Teledyne Continental engines, depending on the tester you are using, you may also need a master orifice tool P/N 646953A to . Understanding the art of the compression check The differential compression check is one of the most useful and telling tricks that mechanics use to diagnose the health of an engine’s cylinders. For owners of aircraft powered by piston engines, the sometimes-dreaded differential compression tester can be looked upon as "the money gauge." If a cylinder fails .However, Lycoming and Continental service specifications call for the use of a standard tester (with a .040" orifice) even if their engine’s bore diameters exceed 5", and for those engines you must comply with the manufacturer's .

However, Lycoming and Continental service specifications call for the use of a standard tester (with a .040" orifice) even if their engine’s bore diameters exceed 5", and for those engines you must comply with the manufacturer's . Looking at a plane with a Continental IO-470-J that was overhauled in 1999 and has about 400 hours since then. Logbook consistently shows compressions in the 60's for all cylinders since 2002. Most recent annual shows 5 in the 60's and one at 45. Prebuy inspection showed all in the 70s and owner.Now you can conveniently check the calibration of your pressure tester before each use (in accordance with Teledyne Continental Service Bulletin M85-15) without disconnecting the tester.

you get the best service from your Continental engine. ~ No engine leaves our factory until it has passed a rigid operational test and inspection. Each engine, therefore, is believed to be free of defects. If any Continental engine or part is suspected of failure or does not perform properly, advise your nearest authorized
To get accurate compression test results, the test needs to be conducted properly. This means that the engine needs to be warmed up to operating temperature, the compression tester needs to have been calibrated, and the procedure in the maintenance manual needs to be followed exactly. aircraft Pilots Operating Handbook/Aircraft Flight Manual (POH/AFM), for a duration that will allow the engine oil and cylinder head temperatures to stabilize, or at least 45 minutes. Perform an additional differential compression test on the suspect cylinder(s).
Most of us fly aircraft powered by piston engines, a basic technology dating back to the late 19th century. Meanwhile, the modern air-cooled aircraft piston engine's basic configurations hasn't changed since before WWII.
