HOWO Parts - Premium Hollow Banjo Bolt (Part No. VG1246080014)

The VG1246080014 Hollow Bolt (commonly referred to as a Banjo Bolt) is a fundamental piece of the HOWO parts ecosystem, designed specifically for fluid passage in Sinotruk WD615 and D12 engine series.

Technical Specifications

1. Always Replace Washers: Whenever you loosen or replace the VG1246080014 hollow bolt, you must use new copper or bonded seal washers. Reusing old washers is the most common cause of persistent leaks in the fuel line.

2. Verify Flow Ports: Before installation, ensure the internal bore and side ports of the bolt are free of debris. Even a tiny metal shaving can cause a blockage in the lubrication circuit.

3. Torque Precision: These bolts are hollow and therefore have a lower shear strength than solid bolts. Use a torque wrench to meet Sinotruk's factory specs—over-tightening will lead to the bolt snapping off inside the expensive engine component.
