Removing and renewing camshafts or camshaft bearings - cylinder bank 2 (left-side) — AUDI

🧭 Before you start

Remove the inlet camshaft chain, check TDC, clamp the gear halves with T40096 and slacken the bearing cap bolts in sequence 12 to 1 before lifting out caps and camshafts. Fit the bearing pedestals, insert the camshafts at TDC, fit the matching caps, tie each with cable ties, fit gauge T40311 on its locating pin and tighten the cap bolts. Recheck TDC, remove T40096 and refit the timing chains.

Fits: Audi A5 (8T, 2007–2016), Audi A5 Cabriolet (8F), Audi A4 B8 (8K, 2007–2015)

• Timing position: the crankshaft or camshaft is set and locked during this job
• Special tools named: T40311/1, T40311

Don't miss

• Clamp the split inlet gear with T40096 so the tooth faces align before removal and refit.
• Loosen the bearing cap bolts in the sequence 12 to 1.
• Do not damage roller rocker fingers or hydraulic compensation elements when lifting camshafts.
• Use cable ties and gauge T40311 to keep bearings straight while tightening.
• Check the TDC position again before removing T40096.

📋 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. 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.]

6. Carefully detach bearing caps and camshafts.
7. 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).
8. Tighten the clamping tool using the knurled wheel so that the faces of the gear teeth are in alignment.
9. Fit camshaft bearing pedestals "“I, II and III”" on cylinder head.
10. Fit camshaft bearing pedestal "“IV”" on cylinder head.
11. Check that bearing pedestals are positioned correctly:
12. Insert camshafts in bearing pedestals in "“TDC”" position.
13. Fit matching bearing caps on bearing pedestals.
14. 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.]
15. Fit bolts (1 … 12) in bearing caps.
16. Screw locating pin T40311/1 into threaded hole (1) in line with cylinder 5, as shown in illustration.
17. Fit gauge T40311 onto support brackets (arrows) for clamping pieces, as shown in illustration.
18. Tighten bearing cap bolts .
19. Check "“TDC”" position of camshafts:
20. Remove camshaft fitting tool T40096.
21. Install camshaft timing chains .
