Remove
- 1. Remove sheathed glow plugs
- 2. Raise vehicle by its full height
- 3. Remove the engine cover and right engine splash guard
- 4. Move crankshaft in direction of engine rotation to "Cylinder No.1 combustion stroke TDC • Marks (1) must align with each other
Note. The cams of the cylinder No. 1 must point upward -- they can position can be checked through the oil filler pipe. If the cams of the cylinder No. 1 do not point upward, rotate the crankshaft one revolution to the cylinder No. 1 combustion stroke TDC
- 5. Put assistance marking on portional vibration damper • The assistance marking must be located precisely 180° from the TDC marking
- 6. Lower vehicle by its full height
- 7. Unscrew the oil filler pipe cover
Important. Slowly and cautiously opened the coolant expansion tank cover. Burn hazard
- 8. Unscrew coolant compensation tank cover
- 9. Remove oil dipstick
Measure
- 10. Calibrate pressure loss gauge
Note. Follow manufacturer's instructions
- 11. Attach compression-loss tester to cylinder 1 • Use KM-6367
- 12. Engage 4th gear, put the handbrake on
- 13. Check pressure loss in cylinder 1 • Max. pressure difference between the individual cylinders 10% approx. • The pressure loss per cylinder should not exceed 25% • Check escaping air to localise the damage on: – intake ducts – exhaust system – Coolant compensation tank, oil dipstick guide tube – oil filler port – Tapped hole for sheathed glow plug
- 14. Move adapter and compression-lost tester to cylinder 3
- 15. Repeat pressure loss test on cylinders 3, 4 and 2
Note. Continue rotating crankshaft by 180° to the assistance marking or the TDC marking
