Note. Do not tighten.

Scheme 588

Use drift 9995450 .

Lubricate the surface of the seal that the camshaft rotates against.

Press in the seal until the drift bottoms out.

Note. If there are grooves on the camshaft, the seal can be pressed in a further 2 mm: Reverse the sleeve.

Install camshaft adjustment tool 9995452 at the rear of the camshafts.

Ensure that the screws retaining the adjustment tool to the camshafts and the screws holding the tool together are well tightened.

Scheme 589

Use drift 9995718 for camshaft with variable valve timing unit and drift 9995719 for camshaft without variable valve timing unit.

Lubricate the surface of the seal that the camshaft rotates against.

Use the variable valve timing unit / timing belt pulley mounting screws. Tighten the screws until the drift bottoms out.

Remove the drift.

Install the screw holding the inner timing cover to the cylinder head.

Tightening the nuts for the lower torque rod
