GRM drive - the general information, service of components

The gas-distributing chain can be replaced without engine dismantling. By means of listed below tools the new chain can be connected to old, is passed round asterisks and зачеканена.

At the wrong assembly there can be a collision of valves with the bottoms of pistons!

     PERFORMANCE ORDER

    1. Disconnect a negative wire from the battery.
    2. For the purpose of simplification of a provorachivaniye of the engine turn out all glow plugs.
    3. Bring a cranked shaft into position VMT of the piston of the first cylinder (1).
    4. Check correctness of combination of adjusting labels of camshafts (2).
    5. Before starting performance of repair procedures remove assembly of a natyazhitel (3).
    6. At TNVD removal/installation the cranked shaft should be brought into situation 15 ° after VMT of the piston of the first cylinder (4).
    7. Before a reversing of a bolt (5) establish the tool No. 601589051400 aligning an asterisk.

    The bolt of an asterisk of TNVD has the left cutting.

    8. After removal of TNVD establish a lock bolt (6), - the tool No. 601589052100.
    9. At installation of an asterisk of a camshaft track correctness of an arrangement of a directing pin.
