OEM Reference

119350, 119290, 119291, 119292, 119293, 119340, 119341, 119342, 112300, 115120, 119270, 119190, 119310, 119320, 119300, 119301, 119302, 119303

OEM numbers are for reference purposes only and do not imply that the tools are original equipment.

Required preliminary work:

• Remove ignition coils, spark plugs, and valve cover
• Remove VANOS adjusters (during removal, turn the shaft clockwise)
• Remove the serpentine belt and both solenoid valves
• Set engine timing and lock the crankshaft at TDC – as follows:
  • Both camshaft lobes point upwards
  • Check camshaft adjusters for locking: insert adapter (to be used like OEM 119270) at the rear and attempt to rotate the camshaft
  • If the adjuster is not locked, rotate the intake camshaft against the direction of rotation to the stop, then rotate the exhaust camshaft in the direction of rotation to the stop
  • The adjusters should now be locked in the initial position; if not, they must be replaced
  • Loosen both camshaft sprocket bolts and secure (lock) the camshafts
• Remove the timing chain tensioner
• Remove camshaft sprocket bolts and take off sprockets (exhaust first, then intake)
• Remove the vibration damper
• Support the engine using an engine support bar
• Remove underbody protection and covers for the radiator and steering gear
• Remove lower brace, loosen steering column, and lower the subframe
• Remove the oil pan

Removal:

• Remove crankshaft hub using a counter-hold tool
• Remove upper chain guide
• Remove guide rail mounting pins (located under the sealing plugs)
• Remove the timing chain assembly upwards

Installation:

• Observe installation direction of the crankshaft sprocket (teeth facing the timing cover)
• Thread the sprocket into the timing chain assembly and install it from above
• First install and tighten the lower guide pin (top view: left above the crankshaft), then install sealing cap
• Install upper guide pin (next to oil filter housing) and fit sealing cap
• Install crankshaft hub; tighten bolt only hand-tight initially
• Align the balance shaft – note: three different versions may be installed
• Tighten crankshaft central bolt (with TDC locking pin inserted) to 60 Nm
• Install solenoid valves and the upper chain guide bolt with sealing cap and tighten (connect impulse sender plug)
• Tighten upper chain guide
• Install camshaft sprockets (do not mix them up!) and lightly secure with trigger wheels and bolts
• Install chain tensioner dummy tool and apply light preload
• Align and install the trigger wheel locking tool at the front of the cylinder head
• Loosen camshaft bolts by 1/2 turn, then retighten hand-tight
• Preload timing chain tensioner to 0.6 Nm (recommended tool: Art. No. 106650)
• Tighten camshafts: 20 Nm + 2 × 90°
• Install OE chain tensioner: 65 Nm
• Rotate engine twice and recheck timing
• It is recommended to replace the crankshaft oil seal at this stage (use tool Art. No. 112483)
• Reassemble engine, reset adaptation values if necessary, and check fault memory
