How does each tool in the set help during a timing or Vanos job?

Every piece has a dedicated role to ensure accurate timing alignment and safe handling of camshafts and the variable timing unit. Using purpose-made pins and plates reduces the risk of misalignment when removing or installing the timing chain or camshaft assemblies.

• Camshaft alignment plate & fixing base: hold camshafts at the correct position for removal or installation
• Flywheel/crank alignment pin: secures crankshaft position for timing verification
• STDC locking pin and timing pin: lock timing components to prevent rotation during service
• Timing chain pre-tensioning tool: sets chain tension consistently when reassembling

What materials and build quality should I expect from the Yuesstloo kit?

The set is manufactured from hardened steel designed for routine workshop use. Surfaces are treated to resist rust and wear so the fixtures remain accurate and dependable through repeated cycles of installation and removal.

• High-hardness steel construction resists bending and breakage
• Corrosion-resistant finish for long service life
• Precision-machined contact surfaces for reliable alignment
• Molded carry case keeps all components organized and protected

What comes in the box and how does it make the job easier?

The kit supplies the critical locking tools and accessories needed for a full camshaft/Vanos timing service, plus extras that simplify workshop workflow and storage. Parts are laid out in a fitted case so technicians can quickly identify and retrieve each tool.

• Complete set: camshaft alignment tool, fixing base, replacement alignment plate, STDC locking pin, timing pin, crank/flywheel alignment pin, timing chain pre-tensioner
