Timing Drive Gear ⚙️ for High-Pressure Fuel System

Keep your engine in perfect rhythm with this OE-grade drive gear. It sits on the high‑pressure fuel pump shaft and links to the timing chain, keeping injection events synced to the crankshaft. Precise timing means clean starts, strong torque, and low emissions ⛽.

Why you need it

Diesel and direct‑injection setups rely on accurate fuel pressure at the exact crank angle. A worn or damaged gear creates timing error and pressure loss. Replacing it restores smooth power, stable idle, and reliable cold starts.

How it works

The hardened teeth mesh with the timing chain, transferring rotation to the pump at a fixed ratio. A machined hub centers the gear, while the key/locator keeps alignment true. Balanced geometry reduces chain whip and noise for long service life.

If it fails

Expect hard starting, rough idle, rattling chain, low rail pressure codes, poor fuel economy, and limp mode. Severe wear can cause chain skip or metal shavings, risking no‑start and internal damage.

Pro tips ️

Install with timing marks aligned. Inspect chain, guides, and tensioner; replace if stretched. Use new bolt where required and torque to spec. Prime the fuel system after assembly.
