1 | Remove cylinder head | ||
| Inspect | ||
2 | Remove gasket residues, if present, on the plane faces of the cylinder head | ||
3 | Inspect cylinder head sealing surface (1) for flatness, cracks and shrink holes | Permissible unevenness | |
Inspect flatness of cylinder head sealing surface over entire length and diagonally with knife-edge straightedge (2). If the inspection is carried out in the transverse direction, the permissible variation stated is merely a reference value and cannot be measured. If a light gap is recognizable and if the stated dimension is thus exceeded, the cylinder head must be faced. | |||
| Measuring | ||
4 | Measure height (H) of cylinder head | Parallelism, minimum height If the stated dimension is exceeded, the cylinder head must be faced. Check whether a stock removal down to the minimum height is still possible. If the minimum height of the cylinder head is already achieved or if the height is below this, no further stock removal is possible, and the cylinder head must be replaced. | |
| Dismantling | ||
5 | Remove valves | If sealing surface of cylinder head has to be machined. | |
6 | Remove injection nozzle with nozzle holder | If sealing surface of cylinder head has to be machined. | |
7 | Machine cylinder head sealing surface | Permissible peak-to-valley height, minimum height Only if sealing surface of cylinder head has to be machined. Clean any soiling and swarf off cylinder head after machining. | |
| Assembling | ||
8 | Install valves | If the valves have been removed. | |
9 | Install injection nozzle together with nozzle holder | If injection nozzle and nozzle holder have been removed. | |
| Measuring | ||
10 | Measure projection of injection nozzles | If the measurement obtained is not within the tolerance, this must be corrected by inserting nozzle disks of appropriate thickness. | |
| |||

11 | Measure valve setback | ||

If the measurement obtained is not within the tolerance, the valve seats must be machined or replaced if necessary: | |||
Replace valve seat rings | |||
