1199175010 Toyota WASHER, BALANCESHAFT THRUST, Price: 7.24$, Weight: 0.099kg

Engine Balance Shaft Thrust Washer

This small but critical washer is fitted in the balance shaft area to control side-to-side (thrust) movement of the shaft inside the engine. It helps keep rotating parts aligned, reduces vibration, and protects the housing surfaces from metal-to-metal contact ⚙️.

Why this part is needed

Balance shafts spin at high speed to cancel engine vibration. Without a proper thrust surface, the shaft can “walk” along its axis. This washer provides a smooth bearing face so the shaft stays in the correct position and oil film can do its job 🛢️.

How it works

The washer sits between the shaft and its support point, taking thrust load while allowing free rotation. Its hardened, low-friction surface helps maintain correct clearance, supports stable oil pressure around the shaft, and keeps timing-related components from drifting.

What happens if it’s worn or broken

Excess play can cause knocking or scraping noises, extra vibration, rapid wear on the shaft and block, and debris in the oil. In severe cases it may lead to poor balance shaft operation, loss of smoothness, and costly internal engine damage 🚗.
