4. INSTALL CHAIN SUB-ASSEMBLY (for Bank 1)


    A149464E01

  1. Align the No. 1 chain's orange mark plates with the camshaft timing gear's timing mark, and attach the chain to the gear as shown in the illustration.



    A149462E01

  1. Align the No. 1 chain's orange mark plate with the crankshaft timing gear's timing mark, and attach the chain to the gear as shown in the illustration.



    A149463E01

  1. Align the No. 2 chain's mark plates (yellow) with the timing marks of the camshaft timing gear assembly and camshaft timing exhaust gear assembly, and attach the No. 2 chain to the gears as shown in the illustration.

    УКАЗАНИЕ:
    The crankshaft timing gear and camshaft exhaust gear assembly will be installed with the No. 1 and No. 2 chains connected to the gears.

  1. Install the crankshaft timing gear to the crankshaft.

  1. Align and attach the knock pin of the No. 3 camshaft with the pin hole of the camshaft timing gear assembly.

  1. Using the hexagonal portion of the No. 4 camshaft, align and attach the knock pin of the No. 4 camshaft with the pin hole of the camshaft timing exhaust gear assembly.

    ПРИМЕЧАНИЕ:
    Because the gears' timing mark positions may shift due to looseness of the No. 1 chain, use the hexagonal portion of the camshaft to hold the No. 3 camshaft in place until the No. 1 chain tensioner is installed.

  1. Remove the pin from the No. 2 chain tensioner.



5. INSTALL CHAIN TENSIONER SLIPPER (for Bank 1)

УКАЗАНИЕ:
If you cannot install the chain tensioner slipper due to the tension of the chain, use the hexagonal portion of the camshaft to loosen the chain and install the chain tensioner.



6. INSTALL NO. 1 CHAIN TENSIONER ASSEMBLY (for Bank 1)


    A148260E01

  1. Move the stopper plate upward to release the lock, and push the plunger deep into the tensioner.
