IMPORTANT The tooth flanks (2a, 2b) are pressed against one another under spring tension. Ensure that the tooth backlash compensation is arrested before installing the camshaft adjuster.

  1. Insert retaining bolt (01b) for tensioning tool (01) in to camshaft adjuster (2).

    IMPORTANT The tensioning tool (01) should make even contact with the camshaft adjuster (2).

  2. Screw in bolt (01s) as far as possible.

IMPORTANT This causes the quadrant (01z) to arrest the tooth flanks (2a, 2b) on the camshaft adjuster (2) in relation to one another.
