Removing and installing camshaft drive timing chain, vehicles with vacuum pump — VW

🧭 Before you start

Fits: VW Touareg I (7L, 2002–2010)

• Special tools named: 27 mm open-end spanner

Don't miss

• This position is only reached after every 4th turn.
• If the journal for vacuum pump drive is not vertical: remove camshaft bar T10068 A. Turn crankshaft further in direction of rotation until the journal is vertical and the camshaft bar T10068 A can be inserted.
• Some of the timing chain links are copper coloured. These chain links are to be used as an aid to installation. The 3 copper-coloured chain links next to each other must be placed on the oil pump chain sprocket.
• First, fit timing chain onto oil pump chain sprocket. Marking must align with middle copper coloured chain link (A).
• Fit timing chain onto chain drive sprocket of high-pressure pump. Marking must align with copper-coloured chain link.

🔩 Torque settings

Values can differ between engine variants — check the code stamped on your block.

ℹ️ Always cross-check the exact figure against your vehicle's factory manual before final tightening — a wrong torque can damage the engine. These values are extracted from workshop data and may not cover every variant or revision.

📋 Procedure

1. Turn engine -at vibration damper- to setting marks. [Note: This position is only reached after every 4th turn.]
2. Secure position of high-pressure pump chain drive sprocket using adjusting tool T10363. The marking (A) on the drive cam for high-pressure pump must be on top. [Note: If the journal for vacuum pump drive is not vertical: remove camshaft bar T10068 A. Turn crankshaft further in direction of rotation until the journal is vertical and the camshaft bar T10068 A can be inserted.]
3. Removing camshaft adjuster .
4. Unscrew securing bolts (1) and (2). Remove guide rail (A).
5. Take timing chain out upwards.

6. Insert timing chain through hole in cylinder head from above.
7. Fit guide rail (A) and, initially, only tighten bolt (2). [Note: Some of the timing chain links are copper coloured. These chain links are to be used as an aid to installation. The 3 copper-coloured chain links next to each other must be placed on the oil pump chain sprocket.]
8. First, fit timing chain onto oil pump chain sprocket. Marking must align with middle copper coloured chain link (A).
9. Fit timing chain onto chain drive sprocket of high-pressure pump. Marking must align with copper-coloured chain link.
10. Tighten bolt (1) for guide rail.
11. Insert inlet camshaft adjuster »24E« into timing chain in such a way that the copper-coloured chain link is aligned with the marking on the camshaft adjuster. Bolt camshaft adjuster onto camshaft and tighten bolt hand-tight.
12. Insert exhaust camshaft adjuster »32A« into timing chain in such a way that copper-coloured chain link is aligned with marking on camshaft adjuster. Bolt camshaft adjuster onto camshaft and tighten bolt hand-tight.
13. Check position of copper coloured chain links to adjustment markings. [Note: The copper coloured chain links no longer align with the adjustment markings once the crankshaft has been turned.]
14. Install tensioner for timing chain (arrow). Specified torque 50 Nm. — 50 Nm (37 lb-ft)
15. Remove adjusting tool T10363 and camshaft bar T10068 A and tighten camshaft adjuster. Specified torque: 60 Nm + 1/4 turn (90°). [Note: Only counterhold at camshaft with 27 mm open-end spanner (arrow). The camshaft bar T10068 A must not be fitted when camshaft adjuster is loosened or tightened.] — 60 Nm (44 lb-ft)
