Solving the Global Drivetrain Dilemma
A single bus fleet often spans two generations of belt technology: classic dual V-belts on older heavy-duty chassis (Americas, Africa, CIS) versus modern 8-groove Poly-V belts on European, Chinese and Japanese platforms. The Valeo TM43 answers both – the same 10-cylinder core, offered with a 2B dual-groove pulley or an 8PK multi-ribbed pulley.
At 425 cm³/rev, the TM43 is the mid-to-heavy commercial vehicle workhorse: municipal buses, intercity coaches, 30+ ton logistics trucks and refrigerated transport.
