• Check the TDC positions of the camshaft sprockets. • Check valve clearances. • Clean the threads of the securing screws for the chain guide, coat threads with Loctite 243 and install the screws. Installing cylinder head cover • Before installing the cylinder head cover, remove all traces of the gasket and clean the sealing face with degreasing agent. Also clean the groove and the seating faces for the gasket. L Note: Do not reinstall the unit consisting of intake air si- lencer, intake duct and battery carrier at this stage, if the fuel filter has to be removed. Make sure that the intake pipe is correctly seated on the throttle valve stub.
E000380 • Turn the bucket tappet until the shim (arrow) can be levered out at the groove in the bucket tappet. • Before installing new shims, check thickness with a micrometer. • Position the shim in the bucket tappet. e Attention: Check that the shim is correctly seated in the bucket tappet. • If necessary, top up the coolant in the expansion tank.

L Note: TDC position: Marks on the timing-chain sprockets must be parallel with the cylinder head, the bores in the timing-chain sprockets are at the top. • Before installing the chain guide, remove the lo- cating screw and install the screw plug, fitted with a new sealing ring.
• Turn the engine over once and bring it to TDC. 00.41
