How to Replace the Timing Belt on the Skoda Octavia 1.9 TDI

To change the timing belt on the Skoda Octavia 1.9 TDI, proceed as follows: in the video, the engine is disassembled and placed on a special engine trolley. The tools used in the video are as follows: Timing belt kit with water pump (code ct1044 wp1), torsional vibration damper (code vd1089), fitting set (code ms17), special tools (code tool box v01). Start by removing the valve cover, then manually rotate the engine until the markings on the crankshaft align so that the engine is at top dead centre.

Insert a locking pin into the injection pump and a template into the camshaft. Now loosen the toothed wheel of the injection pump by removing the locking pin and unscrew the bolts using a counterhold.

After correctly setting the timing, re-lock the injection pump, loosen the timing belt by adjusting the nut on the tensioner. After removing the belt, take out the template from the camshaft, and loosen the corresponding toothed wheel (to remove it from the cone, you will need a puller).

Now proceed to replace the components. When fitting the new tensioner, ensure the nose is positioned in the upper slot.

Once all new components from the kit are installed, proceed to install the timing belt, ensuring the injection pump wheel is centrally positioned relative to the slots. Now fit the timing belt anti-clockwise, starting from the crankshaft, passing over the injection pump toothed wheel, and finally over the camshaft wheel, which you insert in position with the belt.

The belt and camshaft toothed wheel are now fitted. Tighten the toothed wheel bolt by hand first, then after tensioning the belt, tighten it to the specified torque: to tension the belt, use a two-tooth spanner on the eccentric of the tensioner, turning it clockwise until the groove and tongue of the tensioner align.

Remove all locking tools, then secure the camshaft toothed wheel to the specified torque and tighten the 3 bolts of the injection pump. Rotate the engine twice and check the timing again.

If everything is set correctly, you can reassemble the timing belt cover and then the vibration damper. When fitting the new vibration damper, pay attention to its specific position: the damper has 4 holes, one of which is larger, and there is a small pin at the bottom of the crankshaft wheel.

For correct fitting, the large hole must align with the pin; otherwise, the toothed wheel may wobble, and the operation is complete.
