Now you can conveniently check your engine's leakdown rate against a calibrated standard to instantly determine if your engine's cylinder leakage is within the manufacturer's limits. Differential Compression Test (AC 43.13-1B) The differential pressure tester is designed to check the compression of aircraft engines by measuring the leakage through the cylinders caused by worn or damaged components. The operation of the compression tester is based on the principle that, for any given airflow through a fixed orifice, a .Model E2A Tester, for cylinders of less than a 5.00 inch bore* with a .040 inch diameter orifice, that eliminates all guess-work by enabling you to determine the exact location and cause of your engine's efficiency loss.

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 .
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 procedure, passed on from journeyman mechanic to apprentice, and later taught in A&P schools and documented in various textbooks and .NOTE: The ATS 2EM Differential Pressure Tester has a .040” orifice as required by Teledyne Continental SB03-3 Service Bulletin, and is the proper type of instrument to test ALL Teledyne Continental engines in accordance with the .Is this the recommended compression tester for the 180hp Lycoming IO360? The tool manufacturer recommends to use the larger orifice unit for engines with a bore size larger than 5". We always suggest referring to the maintenance .
For one thing, the differential compression test is spectacularly unreliable. This means that you can test a cylinder multiple times and get wildly different test results. A cylinder whose compression reading is abysmal can .This differential pressure tester has a .060" orifice and is intended for use with engines whose bore diameters exceed 5" per AC43.13 REV 1B. 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 .

The differential compression test is a timer-honored tradition in aviation. Because of this, we sometimes do it by rote and forget why we perform this test, its benefits, and shortcomings. The compression test measures the ability of an aircraft engine cylinder to hold air pressure at top dead center (TDC).
As an aircraft owner, you have an interest in monitoring the sealing of each cylinder. The classic method is a differential pressure test, also known as a leakdown. It is generally performed at each required inspection interval and any time cylinder health is in question. First, a few words about safety.ISSUED REVISED PAGE NO REVISION MO DAY YEAR MO DAY YEAR 6 of 14 03 28 2003 P.O. Box 90 Mobile Alabama • 251-438-3411 SB03-3 a) Make sure the Regulator Pressure Valve is backed all the way OUT. b) Make sure the Cylinder Pressure Valve is OFF or Closed. c) Remove the protective caps from both ends of the Master Orifice and install the
Builders: One of the things I do to test motors after their first run is a quick differential compression test. The two gauges show the regulated supply air at 80 psi, and the other shows the pressure in the cylinder at TDC. there is a tiny calibrated orifice between the gauges. If the leak down.
NOTE: The ATS 2EM Differential Pressure Tester has a .040” orifice as required by Teledyne Continental SB03-3 Service Bulletin, and is the proper type of instrument to test ALL Teledyne Continental engines in accordance with the aforementioned bulletin. The ATS 2EM also complies Textron Lycoming SI-1191A Service Instruction and is appropriate for ALL Textron Lycoming .This tester comes complete with on-off safety valve to eliminate pressure when disconnecting from the cylinder. Can be used to check intake or exhaust valves, cracked or worn rings, defective cylinders, worn bushings, etc. Specifications: Orifice size is .040". precision gauges matched to within +/-2%. 18MM plug adapter. 24" pressure hose. The Model 2EM Differential Cylinder Pressure Tester combines the features of our popular 2E tester and a Master Orifice into one tool. Now you can conveniently check your engine's leakdown rate against its built-in calibrated standard to instantly determine if your engine's cylinder leakage is within the manufacturer's limits. I understand there are two types of differential testers, one with a master orifice (Continental spec) and one without. When looking at compression test results, I will frequently see results with a MO noted. Can someone explain the principal role the MO plays in performing the compression test, .
The FAA’s maintenance bible, Advisory Circular AC 43.13, gives a good description of a differential compression tester and how to use it, along with a schematic (see illustration). Basically, it consists of a pressure regulator, two pressure gauges with a restrictor orifice between them, and a connection to the spark plug hole in the cylinder .
