    CAUTION: If bolts are re-used, check their outer diameter before installation. Follow the "Balancer Unit Bolt Outer Diameter" procedure.
    CAUTION:
    • Check tightening angle using Tool or a protractor. Do not make judgment by visual check alone.
    • In step 3, loosen bolts in reverse order as shown.
    NOTE: Apply new engine oil to threads and seat surfaces of bolts.

    • Make sure that crankshaft sprocket is positioned with mating marks on cylinder block and crankshaft sprocket meeting at the top.
    • Install it by aligning mating marks on each sprocket and balancer unit timing chain.
    • Secure the hexagonal portion of the balancer shaft using a suitable tool. Tighten the balancer unit sprocket bolt to the specified torque.
      NOTE: Install crankshaft sprocket, balancer unit sprocket and balancer unit timing chain at the same time.
  5. Install balancer unit timing chain tensioner.

    • Install by aligning mating marks on each sprocket and timing chain.
    • Before and after installing chain tensioner, check again to make sure that mating marks have not slipped.
    • After installing chain tensioner, remove stopper pin, and make sure that tensioner moves freely.
      CAUTION:
      • For the following note, after the mating marks are aligned, keep them aligned by holding them with a hand.
      • To avoid skipped teeth, do not rotate crankshaft and camshaft until front cover is installed.
      NOTE: Before installing chain tensioner, it is possible to change the position of mating mark on timing chain for that on each sprocket for alignment.
  7. Install front oil seal to front cover. Refer to [FRONT OIL SEAL: REMOVAL AND INSTALLATION ].
  8. Install O-rings to cylinder head and cylinder block.
  9. Apply a continuous bead of liquid gasket with the tube presser to front cover as shown, using Tool.

    Tool number: WS39930000 (-) 

    Use Genuine RTV Silicone Sealant or equivalent.  Refer to [RECOMMENDED CHEMICAL PRODUCTS AND SEALANTS ].

    NOTE: Application instruction differs depending on the position.
    Detail of A: Cross over the start of the application and the end.
    Detail of B: Apply liquid gasket outside of bolt holes. (For all bolt holes other than B, apply to the inside.)
    Detail of C: Between here only, apply 4.5 - 5.5 mm (0.177 - 0.217 in) dia.
  10. Make sure that mating marks of timing chain and each sprocket are still aligned. Then install front cover.
    CAUTION: Be careful not to damage front oil seal by interference with front end of crankshaft.
  11. Tighten bolts in numerical order as shown.

    • Use the following for locating M6 bolts.

      Bolt position Bolt length 

      5, 10, 14, 17: 45 mm (1.77 in) 

      Except the above: 20 mm (0.79 in) 

      (Except 1 through 4) 

    • Tighten bolts to the specified torque.

      Bolt position Torque specification 

      5 through 17: 12.8 N.m (1.3 kg-m, 9 ft-lb) 

      1 through 4: 49.0 N.m (5.0 kg-m, 36 ft-lb) 

  12. After all bolts are tightened, retighten them to the specified torque in numerical order as shown.
    CAUTION: Be sure to wipe off any excessive liquid gasket leaking to surface for fitting oil pan.
  13. Install chain guide between camshaft sprockets.
  14. Install O-rings to the camshaft sprocket (INT) insertion points on backside of intake valve timing control cover.
