Deutz Injector Clamp Bolt - OEM Number: 04123112

The Deutz Injector Clamp Bolt (OEM 04123112) is a genuine replacement injector retaining bolt designed for use on a range of Deutz diesel engines. It forms a critical part of the fuel injection system by securing the injector clamp and hold-down assembly, ensuring the fuel injector remains correctly seated within the cylinder head during engine operation. Deutz parts catalogues identify OEM 04123112 as the injector clamp retaining bolt, commonly described as a Torx-head bolt used alongside the injector clamp, clamping shoe, and sealing components.

Manufactured to OEM specifications, this high-strength fastening bolt is engineered to withstand the extreme temperatures, vibration, combustion forces, and cyclic loading encountered within modern diesel engines. Correct clamping force is essential to maintain injector sealing integrity, prevent injector movement, and ensure reliable engine performance.

FUNCTION AND OPERATION

• Secures the injector hold-down clamp assembly
• Maintains correct injector seating within the cylinder head
• Prevents injector movement caused by engine vibration and combustion forces
• Supports effective sealing between the injector and cylinder head
• Helps ensure correct fuel injection performance
• Designed for heavy-duty industrial and construction diesel engines

Deutz parts documentation lists 04123112 as the bolt used with the injector clamp (04123075), clamping pad/shoe (04130374), sealing washer, and injector assembly on various Deutz common-rail engines.

TYPICAL APPLICATIONS

Suitable for a range of Deutz diesel engines, including:

• Deutz 2.9L diesel engines
• Deutz 3.6L diesel engines
• Common-rail fuel injection systems
• Industrial power units
• Construction equipment
• Agricultural machinery
• Generators and engine-driven equipment

The bolt is commonly found within injector retention assemblies where it secures the injector clamp directly to the cylinder head.

IMPORTANT INFORMATION

Always confirm the correct OEM part number, engine model, and engine serial number before ordering, as injector retaining hardware can vary between Deutz engine families. Because injector clamp bolts are subjected to significant loading and thermal cycling, it is recommended to inspect the injector clamp, clamping shoe, sealing washer, and cylinder head threads whenever the injector is removed. A stretched, damaged, or incorrectly torqued injector bolt can result in injector movement, combustion gas leakage, poor injector sealing, reduced engine performance, and costly cylinder head repairs. Industry technicians commonly advise following the manufacturer's specified torque procedure and replacing retaining hardware where required during injector service work to ensure long-term reliability.
