Caution | Release rail and clamping pieces to easily fit injection lines tension-free. If necessary, shift rail slightly and turn relevant injector slightly if required. The lines must never be bent or tensioned. Tension would otherwise cause the respective line to break in the long-term. |
|
Note | t
| Then the procedure is described for mounting the new injector lines. The following aspects must be observed when re-using used injector lines: |
| t
| In case of reuse of the high pressure lines the cylinder specific code must be taken into consideration. |
| t
| The high-pressure lines can principally be reuse according to the following test: |
| t
| Check taper seat of respective high-pressure line for deformation and cracks. |
| t
| The bore of the pipe must not be distorted, restricted or otherwise damaged. |
| t
| Corroded lines should no longer be used. |
| –
| If it has not been done yet, loosen securing bolts of fuel rail and ensure that fuel rail can be moved. |
| –
| If it has not been done yet, loosen securing bolts of clamping pieces and ensure that injectors can be rotated. |
| –
| Use vacuum cleaner to remove dirt from taper seat at rail. |
| –
| Clean fuel pipe and end of pipe using cleaning solution and dry with compressed air. |
| –
| Moisten union nut thread with fuel. |
| –
| Remove the new injection lines from the packaging. Remove the sealing plugs and install the line just by itself. |
| –
| Initially hand-tighten high-pressure line union nuts „fully“ on high-pressure pump without tools. |
| –
| Ensure that line is inserted correctly into seat. |
| –
| If necessary, proceed in the same way with other injection lines. |
