Injector Sleeve Guide Bush for New Holland Diesel Engine Fuel System SKU: QT400121

A worn or damaged injector sleeve guide bush compromises fuel injector positioning and sealing, leading to poor fuel delivery, misfiring cylinders, and potential diesel leakage around the injector assembly. This precision-machined guide bush restores proper injector alignment and maintains the critical seal between the fuel injector and cylinder head.

• Exact-fit design ensures proper injector positioning for optimal fuel spray pattern
• Maintains critical sealing between injector and cylinder head to prevent fuel leaks
• Precision-machined tolerances restore factory fuel injection timing accuracy
• Built from materials that resist diesel fuel contamination and high-pressure operation

When your injector isn't sitting properly or fuel is seeping around the injector assembly, this guide bush delivers the precision fix your diesel engine needs. S&H Parts has been helping farmers keep their equipment running since 1969 - call if you need help confirming the right fit for your engine.
