Removing and renewing camshafts or camshaft bearings, cylinder bank 1 (right-side) — AUDI

🧭 Before you start

Fits: Audi Q5 (8R, 2008–2017)

• Timing position: the crankshaft or camshaft is set and locked during this job
• Special tools named: T10172/5, T40311

Don't miss

• Make sure you do not damage the roller rocker fingers and hydraulic compensation elements when removing the camshafts.
• The cable ties help to keep the camshafts and camshaft bearings straight when they are tightened.
• Risk of damage to valves.Do not turn camshafts any further than specified. — Fit bolts (1 … 12) in bearing caps.
• Fit counterhold tool T10172 with adapters T10172/5 on both bolts and turn camshafts approx. 30° in clockwise direction (arrow) until groove (arrow A) in camshaft is aligned with hole (arrow B) for adjustment pin T40060.

📋 Procedure

1. Remove timing chain from inlet camshaft .
2. Check "“TDC”" position of camshafts:
3. Place camshaft fitting tool T40096 on teeth of inlet camshaft so that the two arms of the tool engage on the two halves of the gear (one in each half, as shown in illustration).
4. Tighten the clamping tool using the knurled wheel so that the faces of the gear teeth are in alignment.
5. Pull off adjustment pin T40060.

6. Screw two bolts for camshaft chain sprocket five turns into threaded holes in camshaft, as shown in illustration.
7. Fit counterhold tool T10172 with adapters T10172/5 on both bolts and turn camshafts approx. 30° in anti-clockwise direction (arrow) until groove (arrow A) in camshaft points vertically to sealing surface (arrows B) of cylinder head.
8. ⚠ Risk of damage to valves.Do not turn camshafts any further than specified. — Loosen bearing cap bolts in the sequence (12 ... 1). [Note: Make sure you do not damage the roller rocker fingers and hydraulic compensation elements when removing the camshafts.]
9. Carefully detach bearing caps and camshafts.
10. Place camshaft fitting tool T40096 on teeth of inlet camshaft so that the two arms of the tool engage on the two halves of the gear (one in each half, as shown in illustration).
11. Tighten the clamping tool using the knurled wheel so that the faces of the gear teeth are in alignment.
12. Fit camshaft bearing pedestals "“I, II and III”" on cylinder head.
13. Fit camshaft bearing pedestal "“IV”" on cylinder head.
14. Check that bearing pedestals are positioned correctly:
15. Insert camshafts in bearing pedestals in "“TDC”" position.
16. Fit matching bearing caps on bearing pedestals.
17. Wrap one cable tie (arrows) on each side around bearing pedestal and bearing cap and secure. [Note: The cable ties help to keep the camshafts and camshaft bearings straight when they are tightened.]
18. Pull off adjustment pin T40060.
19. Screw two bolts for camshaft chain sprocket five turns into threaded holes in camshaft, as shown in illustration.
20. Fit counterhold tool T10172 with adapters T10172/5 on both bolts and turn camshafts approx. 30° in anti-clockwise direction (arrow) until groove (arrow A) in camshaft points vertically to sealing surface (arrows B) of cylinder head.
21. ⚠ Risk of damage to valves.Do not turn camshafts any further than specified. — Fit bolts (1 … 12) in bearing caps.
22. Fit gauge T40311 onto support brackets (arrows) for clamping pieces, as shown in illustration.
23. Tighten bearing cap bolts .
24. Fit counterhold tool T10172 with adapters T10172/5 on both bolts and turn camshafts approx. 30° in clockwise direction (arrow) until groove (arrow A) in camshaft is aligned with hole (arrow B) for adjustment pin T40060.
25. Check "“TDC”" position of camshafts:
26. Remove camshaft fitting tool T40096.
27. Install camshaft timing chains .
