Procedure

–  Fit support bracket -10 - 222 A- with rack -10 - 222 A /1- as shown. –  Remove poly V-belt → Chapter.   Caution Nut -2- must not be loosened.

–  Unscrew securing bolts -arrows- for engine mounting. –  Remove complete engine mounting. Loosen or separate the following components: t  Coolant pump pulley t  Tensioning element/belt drive t  Tensioning roller t  Alternator t  Air conditioner compressor t  Crankshaft pulley t  Oil level and oil temperature sender -G266- t  Oil dipstick t  Oil sump t  Control housing/chain drive –  Tighten crankshaft V-belt pulley securing bolt into crankshaft to stop.

–  Turn crankshaft by pulley securing bolt in engine direction of rotation until groove in camshaft appears in Hall sender hole.

–  Locking pin -T10120- must be easily insertable into camshaft.

–  Loosen securing bolt for camshaft toothed belt pulley (use counterhold -3036-).

–  Turn crankshaft by pulley securing bolt in direction of engine rotation until locking pin -T10121- can be inserted into flywheel.

–  Tighten securing bolt -2- for camshaft sprocket -1- to 20 Nm (using counter-hold tool -3036-). –  Then turn bolt 1/4 turn (90°) further using a rigid wrench. –  Remove both locking pins from camshaft and flywheel. –  Turn crankshaft two full turns in direction of engine rotation and check valve timing again → Chapter. Further assembly is basically the reverse of the dismantling sequence.
