WARNING: This page is about a different variant/trim than selected.
Information
- The valve-stem seals can be replaced when installed.
- For removing valve-stem seals that are difficult to reach, use hand-held valve-stem seal pliers.
- Depending on the tool setup, peripheral components at the sides, such as water tank walls or servo oil reservoirs, may first have to be removed.
- The tool can be adjusted to all M6 or M8 studs or internal threads (tool details below).
- The angle of the assembly bar lever can be adjusted according to space requirements.
- Remove camshafts.
- Take hydraulic tappets out of the cylinder head and lay them on a clean surface, arranged according to cylinders and valves. Do not get components mixed up. For details, see
