- Remove necessary covers/gears – Access cam gear
- Inspect timing components – Check for wear
Phase 5-8: Camshaft Timing & Locking
- Align camshaft marks – To factory specs
- Install W470589104000 tool – Lock cam in position
- Verify alignment with tool – No movement allowed
- Install/torque timing gears/chain – To spec
Phase 9-12: Verification & Final Assembly
CRITICAL: W470589104000 Timing Keys
- Remove tool & recheck marks – Double verification
- Reassemble covers & components – Torque sequence
- Prime & start engine – Monitor for codes/noise
- Road/load test & final scan – Confirm performance
Critical Safety Warnings: Cam Timing Errors
MUST AVOID THESE DISASTROUS MISTAKES:
- ❌ Skip TDC verification – Interference risk
