2. On board verification procedure
Component Procedure / location of ID-nos. Remarks
Cylinder head Check ID-no on machined surface (exhaust side). Inspection is recommended at overhaul when the engine is dismantled.
See figure 1
Piston Check ID-no on piston crown. Inspection is recommended at overhaul when cylinder head is removed.
See figure 3
Turbocharger Check ID-no on metal plate on compressor house. Wastegate. Opening pressure 2,55 bar at stroke 1,05 mm.
Unit injector Check ID-no on injector body. Inspection is recommended at overhaul when the engine is dismantled and the injector unit is visible.
Injector nozzle n.a See ID-no on Unit Injector.
Electronic control unit and data set
The data set can be checked by using a diagnostic tool at a service shop.
Charge air cooler
The ID-no is located at the backside of the charge air cooler. The ID-no is stamped on the housing. Inspection is recommended at overhaul when charge air cooler is dismounted.
Compression ratio Determined by the correct piston and cylinder head combination. Inspection is recommended at overhaul when cylinder head is removed.
Camshaft The ID-no. is located at the rear end of the camshaft. Inspection is recommended at overhaul when valve cover is removed and the camshaft is visible.
See figure 2.
Figure 1
Important! The ID-nos that can not be controlled unless the engine is taken apart shall only
be checked at regular overhaul when the engine is taken out of service and dismantled for maintenence. Check only if considerable doubt of the correctness of the ID-no exist. !
