• ‒ → Assemble support device 10-222 A with legs 10-222 A/14 and 10-222 A/15 as shown.
• ‒ Bolt leg 10-222 A/14 to battery tray with bolts M8 x 35/ 8.8 -arrows-.
      Tightening torque: 25 Nm
• ‒ Insert support in lifting eye on right of cylinder head and take up weight of engine.

• ‒ → Remove right assembly mounting securing bolts -1-.

• ‒ → Remove bolts and nuts from engine mounting -arrows- and remove mounting complete.
• ‒ Remove engine bracket from cylinder block.

• ‒ → Remove vibration damper/belt pulley.
• ‒ Remove toothed belt guard centre and lower parts.
• ‒ Mark D.O.R. of toothed belt.
• ‒ Release tensioner and take off toothed belt.
• ‒ Turn crankshaft back slightly.

Installing

Note:

When the camshaft is turned, the crankshaft must not be at TDC. Danger of damage to valves or piston crowns.

A - Toothed belt completely removed

If toothed belt has only been removed from camshaft => Page 15-11

Conditions

• ● The pistons must not be positioned at TDC.

Work sequence

• ‒ → Bring mark on camshaft into line with the mark on cylinder head cover.
• ‒ Place toothed belt on crankshaft pulley and coolant pump (observe DOR).
• ‒ Install toothed belt guard centre and lower parts.
• ‒ Install vibration damper/belt pulley
      Tightening torque: 25 Nm

• ‒ → Turn crankshaft to TDC No. 1 cylinder.
• ‒ Place toothed belt on tensioning roller and camshaft sprocket and tension => Page 15-12.

B - Toothed belt only taken off camshaft sprocket

• ‒ → Bring mark on camshaft into line with the mark on cylinder head cover.
• ‒ Turn crankshaft to TDC No. 1 cylinder.
• ‒ Place toothed belt on the camshaft sprocket and tension => Page 15-12.

Tensioning toothed belt

Conditions

• ● The engine must not be more than warm to the touch.
• ● Engine is at TDC No. 1 cylinder.
• ● Before tensioning toothed belt turn tensioning roller on eccentric with a pin wrench T10020 five times in both directions fully onto the stops.

Work sequence

• ‒ → Tension toothed belt. Do this by turning eccentric to left (direction of arrow) with 2-hole pin wrench T 10020 onto stop.
• ‒ Then release the toothed belt until the notch -1- and indicator -2- align (use mirror).
• ‒ Tighten securing nut to 20 Nm.
• ‒ Turn crankshaft two turns in engine direction of rotation until the engine is again at TDC No. 1 cylinder. When doing this it is important that the last 45° (1/8 turn) is performed without stopping.
• ‒ Check toothed belt tension again
      Specification: indicator and notch align

Continuation, installing toothed belt

• ‒ Fit engine mounting to cylinder block.
      Tightening torque: 45 Nm
• ‒ Install engine assembly mounting.
  Tightening torque => Page 10-16.
• ‒ Install upper toothed belt guard.
• ‒ Install ribbed belt tensioner.
      Tightening torque: 25 Nm
• ‒ Install ribbed belt => Page 13-11.
• ‒ Install battery.
• ‒ Install air cleaner with intake hose:

=> Repair group 24; Servicing injection system; Dismantling and assembling air cleaner.

• ‒ Install engine cover
