Install

10

Install exhaust and intake camshafts (1, 2).

Install: Lubricate the hydraulic elements of valve clearance offset and the camshaft cradles, and then, adjust the intake and exhaust camshafts into the axial sleeve (arrows).

Install the camshafts so that the bores (B) in the gears match and that the marks of the shafts (arrows) and the sleeve covers are aligned. Camshafts are very sensitive to breakage, which is why they should not be tensioned during installation.

When installing the camshafts, note that:

- The exhaust camshaft can be identified via detent located between the two last cams and intended for reading the position sensor.

- For the location of the camshaft in the cylinder head, pay attention to the existing indications on it, located between the first and second sleeve, where:

(A1) is for the exhaust command

(E1) is for intake command.

11

Install the sleeve covers (13) of the camshafts.

Install the sleeve covers (13) in the same place. Tighten the Torx-Head Cap Screws (12) evenly and in steps of a turn and, if necessary

Note the marks in the camshaft/sleeve covers.
