–  Mark the modified tool with “A” at the end of the code number.

Injector: parts 1 -  Radial compensator: replace if damaged 2 -  Replace the combustion chamber seal (Teflon). When fitting, the seal must not be lubricated with any lubricant whatsoever 3 -  Injector channelling 4 -  Support washer (replace) 5 -  O-ring (replace, moisten slightly with clean engine oil when fitting) 6 -  Pressure rings   Note

If the injector unit is fitted, the radial offset -1-is covered by the pressure ring -6-. To remove the injector unit, the support seal should be removed in order to insert the extractor-T10133/2A- in the injector connecting element -3-. removing –  Remove extraction hose → Chapter. –  Use a clean cloth cover any of the open canals. –  Remove the injector connector from the injector to be removed.
