CVT Pulleys, Belts & Hard Parts

Pulley sets, push belts, chains, step motors and planetary hardware for JATCO RE0F, Subaru Lineartronic and other CVT families — dimension-checked, not just visually inspected.

Quick answer: CVT hard parts from TRANSMESUN are dimension-checked, not just visually inspected: pulley cone surfaces, belt width and step motor travel are measured against spec before the part is approved for sale.

Buyer FAQ

Common questions on cvt & hard parts.

Why does dimension checking matter for CVT parts?

CVT performance lives on tolerances: a pulley cone worn by a fraction of a millimetre or a belt 1mm narrower changes line pressure and ratio control. Visual inspection misses exactly the wear that causes repeat failures.

Which CVT families do you cover?

JATCO JF/RE0F series (Nissan, Mitsubishi, Suzuki), Subaru Lineartronic TR580/TR690, and selected Honda/Aisin CVT units. Send your code for exact coverage.
