1363375010 Toyota GEAR, BALANCESHAFT DRIVEN, NO.2, Price: 26.77$, Weight: 0.134kg

Balance shaft driven gear for Toyota engines ⚙️

Why you need this part

This precision gear drives the balance shaft that cancels second‑order engine vibrations. It keeps idle smooth, reduces cabin buzz, and protects bearings, mounts, and timing parts. If you want factory‑level refinement and long engine life, this gear is essential for the balance system to do its job.

How it works

Mounted on the balance shaft, it meshes with the drive gear (from the crank or an idler). Hardened teeth transfer torque and keep exact phase between crank and shaft. Correct phasing lets the counterweights spin in opposition to piston forces, cutting NVH. Oil splash and galleries lubricate the teeth and hub, while tight backlash control prevents rattle.

What happens if it’s bad ❗

• Harsh vibration at 1,500–3,000 rpm and rough idle
• Rattle from the front cover, metal dust in oil
• Misphasing can stress the timing chain/belt
• Accelerated main/rod bearing wear; in worst cases, tooth breakage and debris can damage the oil pump or seize gears

Fitment and quality

OEM‑grade steel, heat‑treated and ground for true pitch. Matches factory backlash and runout specs for Toyota balance drive layouts. Designed to run quietly and hold timing under load.

Install tips

Align timing marks, pre‑lube, and set backlash within spec. Use new fasteners and threadlocker; torque to factory values. Rotate the engine two turns and recheck marks. After replacement, change oil/filter early to capture any old debris.
