Installation

Installation

• When using different types of steel and materials of different strengths, the special tools listed under Special Tools are required to perform body work correctly.

Preparing New Parts

• Wheel housing

• Suspension strut mounting

• Suspension strut mounting reinforcement

• Bulkhead

• Wheel housing reinforcement

• Bar piece

• Plenum chamber






- Drill holes for gas-shielded arc plug weld seam in suspension strut mount, 8 mm diameter.











- Drill holes for gas-shielded arc plug weld seam in wheel housing, 8 mm diameter.

• Distance of holes to each other, approximately 25 - 30 mm.

- Transfer the separating cuts onto the bulk head and on the bar piece and cut.











- Fit and secure the new components using the alignment bracket mountings from the (VAS 6325/2) and the neighboring components.

Welding






- Weld the suspension strut mounting - 1 - to the wheel housing, to the suspension strut mounting reinforcement and the bulk head using a gas-shielded arc plug weld seam.

• The wheel housing longitudinal member - 2 - is mounted only for aligning the wheel housing and the suspension strut mounting reinforcement. It can be removed when welding and drilling the holes for the suspension strut.






- Drill holes - 1 - (10 mm) for bolting suspension strut and also secure suspension strut mounting with reinforcement to alignment bracket mounting - 2 - with screws.






- Weld in wheel housing with suspension strut mounting, gas-shielded arc plug weld seam and straight-line spot weld seam.

- Restore joint between wheel housing and plenum chamber, gas shielded arc plug weld seam.






- Restore original joint between suspension strut mounting - 1 - and bulk head - 2 -, RP spot weld seam.

- Recreate the bulk head original joint - 2 - SG stepped seam.

- Install upper wheel housing longitudinal member.






- Recreate the original joint between the bar piece - 5 - and the wheel housing - 2 - using a straight-line spot weld seam.

- Recreate the original joint between the bar piece - 5 - and the bulk head - 6 - gas-shielded arc plug weld and gas-shielded arc continuous weld.

- Recreate the original joint between the plenum chamber - 1 - and the wheel housings - 2 - and the bar pieces - 5 - with a straight-line spot weld seam.

- Recreate the original joint between the wheel housing reinforcement - 3 - and the wheel housing - 2 - with an RP arc plug weld seam.

- Fit, secure and weld the headland bracket - 4 - using the (VAS 6325/2).

- Fit the A-pillar and weld it.






- Enlarge holes for suspension strut mounting cover cap.

Dimension - a - = 34 mm

• For checking the dimension - a -, use alignment bracket set, Tiguan (VAS 6325/2).

- Install upper wheel housing longitudinal member.
