Measurement of Compression Pressure
Measurement of compression pressurePreparation For Inspection
Check the following before inspection.(1) Make sure that the engine oil, air cleaner, starter, battery, etc. are in normal operating condition.Inspection
(1) Move the control lever to the Stop position.(2) Remove the glow plugs from all cylinders, and attach the gage adapter and compression gage to the cylinder to be tested.(3) Crank the engine with the starter, and read the compression gage indication when the indication stabilizes.(4) If the measured compression pressure is lower than the limit, consider overhauling the engine.
(a) Measure the compression pressure in all cylinders.(b) As compression pressure varies with the engine speed, measure the engine speed at the same time.
Measure the compression pressure while the engine is running at 150 to 200 min-1. The oil and coolant temperatures should be between 20 and 30 °C [68 and 86°F].
It is important to regularly check the compression pressure so that you can tell the difference. * New or overhauled engines have slightly higher compression pressure.* The compression pressure settles to the standard value as the piston rings and valve seats fit in.* As wear progresses further, the compression pressure drops.
