Corteco: TVD pulley kits + bolts are included [Lifetime Guarantee]

Date: Friday 12 February 2021

Pulleys should be checked every 90,000 km and replaced together with the bolts and belt. We know replacement bolts are difficult to identify, but Corteco offers you the widest selection in OE quality.

What can you find in our TVD Pulley Kits?

Purposely designed original pulleys and bolts guarantee straightforward assembly and the highest degree of safety.

Corteco’s portofolio comprises of more than 400 pulleys and kits.



CORTECO recommends replacing the bolts with the pulley.

In serial production torque-to-yield (TTY) bolts are often used, which are tightened by automatic bolt tightening devices to just above their elasticity range. The bolt undergoes lasting deformation and/or stretching.

Re-using such bolts poses considerable safety risks and is not recommended.

As a result of the deformation, the usual ratio between torque and preload cannot be achieved.

Result: the screw can become loose or even break.
