Valve timing procedures

  • Ensure camshaft adjusters set in the installation position as follows:
      • Turn crankshaft two turns clockwise.
      • Turn inlet camshaft slowly anti-clockwise as far as stop [1] .
      • Turn exhaust camshaft slowly clockwise as far as stop [2] .
      • Camshaft rotation possible using spanner at positions shown [3] .
      • Ensure camshafts locked in position.
      • Replace camshaft adjuster, if not locked in installation position.
  • Fit flywheel timing pin [4] .
  • Turn crankshaft clockwise until flywheel timing pin engages [5] .

NOTE: Ensure round section of alignment lobe is facing downwards [6] .

  • Install exhaust camshaft alignment tool [7] .
  • Install inlet camshaft alignment tool [8] .
  • Remove timing chain tensioner [9] .
  • Modify old timing chain tensioner to use as timing chain pre-tensioning tool:
      • Drill a 10,75 mm diameter hole into hexagon end of tensioner body.
      • Insert M10 x 1,5 helicoil and fit M10 x 100 mm bolt with locknut.
  • Install timing chain pre-tensioning tool [10] .
  • Tighten adjusting screw until in contact with guide rail. DO NOT overtighten screw.
  • Pre-load timing chain with pre-tensioning tool to 0,6 Nm.
  • Remove camshaft alignment tools [7] & [8] .
  • Remove flywheel timing pin [4] .
  • Turn crankshaft two turns clockwise.
  • Ensure camshaft adjusters in the installation position.
  • Fit flywheel timing pin [4] .
  • Ensure flywheel timing pin located correctly [5] .

NOTE: Ensure round section of alignment lobe is facing downwards [6] .

  • Install exhaust camshaft alignment tool [7] .
  • Install inlet camshaft alignment tool [8] .
  • Timing correct when camshaft alignment tools abut cylinder head.
  • If not, adjust camshafts as follows:
      • Remove timing chain pre-tensioning tool [10] .

        NOTE: Replace chain, tensioner and guides if ‘X’ more than 73,5 mm.

      • Refit timing chain pre-tensioning tool [10] .
      • Pre-load timing chain with pre-tensioning tool to 0,6 Nm.
      • Remove camshaft alignment tools [7] & [8] .
      • Remove central bolt from each camshaft adjuster [11] .
      • Camshaft rotation can be prevented using 27 mm spanner at positions shown [3] .

        NOTE: Degrease ends of camshafts and camshaft sprockets.

      • Fit new bolts [11] . Finger tighten bolts.
      • Remove crankshaft pulley centre bolt [12] .
      • Fit new crankshaft pulley central bolt [12] . Finger tighten bolt.
      • Install exhaust camshaft alignment tool [7] . If necessary, adjust position of exhaust camshaft.
      • Install inlet camshaft alignment tool [8] . If necessary, adjust position of inlet camshaft.
      • Ensure camshaft alignment tools abut cylinder head. Secure tools with bolts.
      • Tighten crankshaft pulley central bolt [12] . Tightening torque: 50 Nm + 180°.
      • Tighten inlet camshaft adjuster bolt. Tightening torque: 20 Nm + 180°.
      • Tighten exhaust camshaft adjuster bolt. Tightening torque: 20 Nm + 180°.
      • Remove timing chain pre-tensioning tool [10] .
      • Fit new timing chain tensioner. Tightening torque: 75 Nm.
      • Remove camshaft alignment tools [7] & [8] .
      • Remove flywheel timing pin [4] .
