This genuine Nissan injector pump drive gear is a critical timing component for the legendary TD42, TD42T, and TD42Ti diesel engines. Located within the front timing case, this gear is driven by the crankshaft and is responsible for driving the mechanical injector pump. Its precise function is essential for maintaining correct fuel delivery and accurate engine timing.
Over time, the hardened teeth on this gear can wear, which can lead to incorrect fuel timing, resulting in rough running, hard starting, or a complete no-start condition. Replacing a worn or damaged gear with this genuine Nissan part is essential for restoring engine performance and reliability.
Replacing the injector pump drive gear is a complex task recommended for an experienced workshop or mechanic with specialised knowledge of TD42 engine timing. The job requires significant disassembly of the front of the engine and timing case. When replacing this gear, you may also need new gaskets and seals. We recommend checking the condition of related timing components during disassembly.
Please check vehicle fitment to confirm compatibility with your vehicle. Please contact us with your VIN details if you require further assistance to confirm fitment.
Choosing genuine Nissan parts ensures the quality and correct fitment for your vehicle. Unlike some aftermarket alternatives, genuine Nissan parts are manufactured to exacting standards, using materials specifically designed to withstand the rigors of Australian conditions, guaranteeing performance, service life, and reliability. Using an inferior non-genuine gear for a critical timing component risks incorrect fuel timing, poor performance, and potentially catastrophic engine failure.
