CVT servizio set CFORCE 450/520, ZFORCE 550, Terrox 400/500

CVT service kit for complete, professional servicing of the CV-Tech CVT.

The CVT is one of the most critical maintenance points on an ATV, and using high-quality spare parts ensures reliable performance even in demanding situations. Regular maintenance keeps the system operating smoothly and extends the service life of components such as the sheaves and helix.

The service kit includes the wear parts for the variator as well as the variator belt.

We have tested Dr. Pulley wear parts ourselves and found them to be excellent upgrades for the variator. The parts are made from self-lubricating nylon, which reduces friction within the variator. This results in smoother operation and a longer service life; Dr. Pulley variator parts offer twice the durability of original parts.

Gates WorkHorse is a high-quality, durable CVT belt. It is ideally suited for a wide range of applications. Made from a combination of aramid and ethylene elastomer, the belt offers a long service life.

FAQ

Does replacing the belt require special procedures?

Yes. The belt alignment should be checked or adjusted whenever the belt is replaced, and it is advisable to break in the new belt gently during the first few uses to ensure maximum service life.

We also recommend "breaking in" the belt: after installation, drive at least 5 km at a steady pace of 40–60 km/h—without a heavy load and as smoothly as possible—to ensure the belt warms up properly. Then, turn off the ATV and let the belt cool down undisturbed for at least 60 minutes.

Can I install the parts myself?

We recommend having the parts installed by a professional. However, if you are handy with tools, the parts are relatively easy to replace. We also offer variator tools to make the installation easier.

Do the variator parts need to be replaced every time an inspection is performed?

No. The manufacturer's repair manual specifies guidelines for when variator components should be replaced. Based on our experience, it is better to replace wear parts too frequently than not often enough. The variator's performance changes drastically as parts wear, and excessively worn components can lead to costly repairs.

You can also purchase all the components of the package individually if you do not need the entire set.
