INSTALLATION SERVICE POINTS



>>A<< TIMING CHAIN/CAMSHAFT SPROCKET/IDLER WASHER INSTALLATION



1.Using camshaft sprocket holder kit (MH062381), support the camshaft sprocket.

  • A: Nut
  • B: Washer
  • C: Spacer
  • D: Adjust plate
  • E: Bolt
  • F: Nut

2.Check that the mating mark “1” on the idler gear and sprocket assembly is in alignment with that on the crankshaft gear.

3.
caution Note that the timing chain has one mark plate for the idler gear and sprocket assembly side, and two mark plates for camshaft sprocket.
Align the mating mark on the idler gear and sprocket assembly with the brilliant white mark ring plate on the timing chain.

4.Align the mark ring plates with the camshaft sprocket mating marks.
5.Tie up the timing chain and the camshaft sprocket with a cord to prevent the mating mark misalignment.

6.Install the idler washer. The idler washer front mark "F" must face toward the front of the engine.

>>B<< TIMING GEAR CASE ASSEMBLY INSTALLATION


1.Clean the timing gear case and the plate mating surfaces with a scraper or a wire brush.

2.
caution
  • After applying the sealant, install the timing gear case within 15 minutes.
  • When installing the timing gear case, be careful not to disturb the sealant.
  • Whenever the timing gear case mounting bolts are loosened or tightened again after the timing gear case installation, always apply the sealant again.
  • After the timing gear case is installed, wait for at least one hour, and then start the engine.
