Product Description
Product Introduction C4974971 Fuel Injector Clamp is a fixed clamping component for fuel injector assembly of ISZ520 52 heavy-duty diesel engine. It firmly locks fuel injector onto cylinder head, ensuring accurate positioning and stable compression of injector sealing surface during engine operation. This aftermarket replacement clamp solves injector loosening, fuel blow-by and unstable injection caused by clamp deformation, thread wear and metal fatigue of original parts, maintaining good fuel atomization and preventing power drop for long-haul heavy cargo transport vehicles.
Product Advantages Made of high-strength alloy steel through forging and heat treatment, it can withstand strong pressure and engine vibration. Precision machined contact surface provides uniform clamping force without bending easily. Anti-oxidation surface treatment slows down corrosion under high-temperature working environment. Each clamp undergoes load testing before shipment, reliable fixing effect and reduces maintenance risk of fuel injection assembly.
