Measurement of Compression Pressure
Preparation 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].
(a) Measure the compression pressure at regular intervals and keep the record of changes in compression pressure.(b) Compression pressure will be slightly higher when the engine is new or immediately after an overhaul due to tight clearances of piston rings and valve seats, but it decreases to the standard level after the parts break in.
Preparation For Disassembly
Removing Electrical Wiring
Removing electrical wiringDisconnect harness and wires from the following devices.Before disconnecting, attach tags or other indications on the terminals to facilitate reconnection.* Starter* SwitchesDraining Coolant
Draining coolantLoosen the coolant drain plug on the right-hand side of the cylinder block to drain coolant.Draining Engine Oil
Oil pan drain plugRemove the drain plug from the oil pan and drain engine oil.After draining engine oil, reinstall the drain plug and tighten to the specified torque. (Oil pan capacity: 7.5 l [1.98 U.S. gal])
Do not touch hot drained engine oil since it can be hot and cause burns.
