Pressurized air is supplied to each cylinder and in moments displays a rate of leakage measure from 0 to 100. The cylinder leak down test reading is expressed in a percentage.
Otc 5609 Cylinder Leakage Tester Kit
Diesel cylinder leak down tester. Instead of measuring the engines ability to create pressure compressed air is introduced into the cylinder through the spark plug hole. The dual 2 12 gauges read 0 100 psi and 0 700 kpa and feature chrome bezels and rugged protective outer boots. So the great thing about the cylinder leak down test is that. It deals with how well the cylinder is sealing and nothing else. An engine leakdown test is a compression test in reverse. But can give you a more accurate and detailed picture of the engines overall health.
Compressed air 80 to 90 psi is then fed into the cylinder. Consequently good cylinder leakdown readings should be below 5 8. You calibrate the gauge to 0 by turning the regulator then you hook it up to the cylinder. This cylinder leak down tester gauges leak down tests more accurately than standard compression tests. 31 comes with 12mm and 14mm fittings and must be calibrated before each use by manipulating the schrader valve for the regulator. Furthermore the readings are not affected cam timing or even engine cranking speed.
Product description otcs 5609 cylinder leakage tester kit quickly diagnoses internal engine problems like bad rings valves and leaking head gaskets and comes complete with adapters for most applications. A cylinder leak down test requires the removal of all the spark plugs. A threaded coupling is screwed into a spark plug hole. The abn cylinder leak detector appx. The universal rule for cylinder leakage is no more than 30. It is also important to note this type of tester is not rated to measure more than 100 psi.
It will have two gauges one with air pressure and one with leakage and an adj. The best gauge to use is a dual gauge leakage tester. Leak down test kit not a compression tester the performance tool w89729 leak down test kit can quickly diagnose internal engine problems such as bad rings valves and leaking head gaskets. A cylinder leak down test takes more time to perform.
