Weichai belt tensioner 612600061256 for engine accessory-belt repair enquiries.
Weichai belt tensioner 612600061256 is a replacement reference for accessory-belt drive repairs, with supplier references for WP10 and WP12 engines. An automatic tensioner uses a spring-loaded mechanism to maintain belt tension during operation. Confirm the exact engine variant, belt-drive layout and old-part reference before ordering. An engine-family name alone does not establish fitment.

The Hengxin product reference identifies this number as a belt tensioner for WP10/WP12. The BEN-YA Weichai parts catalogue also lists 612600061256 as a WP12 belt tensioner. These supplier references support identification, rather than universal compatibility across all engine versions.
This page concerns a tensioner unit, rather than a pulley-only replacement or a complete belt-drive group. The main image is an edited Hengxin reference photograph showing a tensioner body, arm and pulley. A photograph does not define included belts, separate mounting seats or fasteners. Confirm the actual supplied version and package contents in the quotation.

Belt noise, visible tracking problems, pulley play or abnormal tensioner movement can prompt inspection. These symptoms alone do not identify the tensioner as the only fault. A qualified workshop should inspect belt condition, alignment, associated pulleys and driven accessories before choosing replacement parts.
Check the removed tensioner for damage, bearing roughness, excessive play and problems with the arm or tensioning mechanism. Compare its mounting arrangement and pulley position with the offered replacement. Similar pulley diameter does not establish the correct offset, operating range or engine fitment.
Follow the engine’s service procedure for releasing belt tension, removing the unit and installing the replacement. Confirm the specified belt route and tightening requirements. After installation, check that the belt tracks correctly and the assembly operates within the applicable service limits. Replacing the tensioner will not correct an unrelated accessory or alignment fault.
Fleet workshops, engine repair businesses and parts distributors can prepare a quotation request with:
Specify whether you need the tensioner unit or are enquiring about a pulley-only repair. Confirm the offered configuration, inspection information and package contents before ordering. Stock, price, minimum order quantity, delivery lead time and warranty depend on the quotation. Other tensioner numbers require their own fitment check.
