The <strong>Voith 864.3E<\/strong> (Type B4HTOR2) belongs to the proven DIWA.3 generation. For years, it served as a standard component in numerous European transit buses, most notably the first-generation Mercedes-Benz Citaro.<\/p><h3>Technical Features of DIWA Technology<\/h3><p>The most distinctive feature of this transmission is the DIWA principle (Differential-Converter). Unlike conventional automatic transmissions, Voith utilizes power splitting. During the start-up phase, the transmission operates both mechanically and hydrodynamically. This allows for stepless acceleration over an extremely wide speed range, significantly increasing shifting comfort in heavy city traffic while reducing mechanical wear.<\/p><p>The <strong>864.3E<\/strong> designation provides details on its performance:<\/p><ul><li><p><strong>864:<\/strong> Indicates the torque class (designed for engines up to approx. 1100\u20131300 Nm).<\/p><\/li><li><p><strong>.3:<\/strong> Represents the third DIWA generation.<\/p><\/li><li><p><strong>E:<\/strong> Refers to the electronic control unit (E 200 or E 300), which precisely adapts shift points to load conditions.<\/p><\/li><\/ul><p>The integrated retarder system is another major benefit for mechanics. This hydrodynamic brake operates virtually wear-free, protecting the bus&#8217;s service brakes. This is particularly valuable in stop-and-go operations, as it extends maintenance intervals.<\/p><h3>Application in the Mercedes-Benz Citaro (O530)<\/h3><p>This specific transmission originates from a Mercedes-Benz Citaro. The Citaro is one of the most successful city buses worldwide. During the production years of the Euro 2 and Euro 3 standards, the Voith 864.3E was the preferred choice for transport companies seeking a low-maintenance drivetrain solution. As these vehicles are increasingly replaced in Europe due to stricter emission standards, they are exported globally. In regions such as Eastern Europe, Central Asia, or Africa, these transmissions often continue to perform reliably for decades.<\/p><h3>Why Choose Used Voith Transmissions?<\/h3><p>The Voith 864.3E is renowned for its longevity. Since new parts for the older DIWA.3 series are often expensive or difficult to source, a tested, fully functional used transmission offers an economically viable alternative. It enables cost-effective repairs for vehicles that, despite their age, remain in good overall technical condition. At M\u00f6ller-Scholz GbR, we ensure that mechanical components like the B4HTOR2-8.5E are carefully dismantled from donor vehicles to guarantee their continued serviceability.<\/p><p>Visit our shop at Trucks NL: <strong><a href=\"https:\/\/www.trucksnl.com\/de\/firma\/moeller-scholz-gbr\" target=\"_blank\" rel=\"noopener\">https:\/\/www.trucksnl.com\/de\/firma\/moeller-scholz-gbr<\/a><\/strong><\/p>\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t\t<\/div>\n\t\t<\/div>\n\t\t\t\t\t<\/div>\n\t\t<\/section>\n\t\t\t\t<\/div>\n\t\t","protected":false},"excerpt":{"rendered":"<p>The Voith 864.3E (Type B4HTOR2) belongs to the proven DIWA.3 generation &#8211;
