Bomag Hinge Bolt - OEM Number: 78320212

The Bomag Hinge Bolt (OEM 78320212) is a genuine replacement pivot component designed for use on selected Bomag compaction equipment. Installed within hinge and pivot assemblies, the hinge bolt provides a secure rotational connection between moving components, allowing controlled movement while maintaining correct alignment and structural support.

Manufactured to OEM specifications from high-strength steel, the hinge bolt is engineered to withstand heavy loads, repeated movement, vibration, and the demanding conditions encountered on construction and civil engineering sites. Precision-machined for an accurate fit, it is designed as a direct replacement component to restore smooth operation and reliable performance of the hinge assembly.

FUNCTION AND OPERATION

• Provides a secure pivot point between moving components
• Allows controlled rotational movement within hinge assemblies
• Maintains correct alignment of connected components
• Withstands heavy loads and continuous vibration
• Supports smooth and reliable mechanical operation
• Designed for heavy-duty compaction applications

TECHNICAL DETAILS

• OEM Part Number: 78320212
• Type: Hinge bolt
• Function: Pivot and hinge connection component
• Application: Selected Bomag compaction equipment
• Material: High-strength steel
• Design: OEM direct replacement component

TYPICAL APPLICATIONS

Suitable for selected Bomag equipment, including:

• Tandem rollers
• Single drum rollers
• Soil compactors
• Asphalt rollers
• Other Bomag machines fitted with the compatible hinge or pivot assembly

Always verify compatibility using the machine model and serial number before ordering, as hinge bolts can vary in diameter, length, thread specification, and application between machine models and production revisions.

IMPORTANT INFORMATION

Always confirm the correct OEM part number, machine model, serial number, and hinge assembly specification before ordering, as hinge bolts are manufactured to precise dimensions and load requirements. Installing the correct component is essential to maintain safe operation, correct alignment, and long service life of the hinge assembly.

Common signs of a worn or damaged hinge bolt include excessive movement, looseness within the hinge assembly, unusual noise, visible wear marks, corrosion, bending, or damage to the bolt surface. When replacing the hinge bolt, it is recommended to inspect the associated bushings, hinge plates, retaining hardware, lubrication points, and surrounding components for signs of wear or damage. Replacing worn associated components at the same time will help maximise the reliability and service life of the complete hinge assembly.
