Camshaft Sprocket Holding Tool for VAG 5 & 10 Cylinder Engines

Special clamping tool designed to securely hold camshaft sprockets during removal and tightening procedures on VAG 5- and 10-cylinder engines.

Compatible with:

• VW T5 (from 2004)
• VW Touareg (from 2003)
• VW Phaeton (from 2003)

Function

This tool ensures controlled handling of the camshaft sprocket during timing service. It prevents unwanted rotation and allows precise torque application, reducing the risk of engine timing misalignment or component damage.

OEM Reference

• (T10199)
• (T10199/1)

Tightening Instructions

1. After installing the camshaft sprocket, tighten the center bolt by hand.
2. Install the smaller clamping tool and tighten it to 70 Nm.
3. Before tightening the sprocket, install a crankshaft locking tool to prevent rotation (e.g. from tool set BGS8443 or camshaft locking tool BGS8279).
4. Apply a preload of 80 Nm using the clamping tool while tightening the camshaft sprocket to 50 Nm.
   • ⚠ Always use a new center bolt.

Final Tightening Procedure

1. Remove the clamping tool and install the larger tool (T10199), tightening it to 40 Nm.
2. Ensure the tool sits flush on the cylinder head.
3. Tighten the new center bolt to 150 Nm + 90°.
4. Remove the tool, rotate the engine, and verify timing alignment.

APPLICATION

Loosening the Camshaft Sprocket
Position the camshaft sprocket holding tool (2) onto the camshaft sprocket and loosen the camshaft sprocket bolt (B).

Tightening the Camshaft Sprocket
Insert a torque wrench (A) into the square drive of the camshaft sprocket holding tool (2).

Position the camshaft sprocket holding tool (2) onto the camshaft sprocket (see illustration) and rotate it against the engine’s direction of rotation with the specified torque. This removes play from the gear train.

NOTE:

• Cylinder bank 1 – rotate in the direction of the arrow
• Cylinder bank 2 – rotate against the direction of the arrow

Position the camshaft sprocket holding tool (1) onto the camshaft sprocket. Then tighten the camshaft sprocket to the specified torque.
