L3Y211SK0 Mazda METAL SET,THRUST, Price: 48.79$, Weight: 0.07kg

Crankshaft Thrust Bearing Set for Mazda Engines

This precision thrust bearing set keeps the crankshaft centered in the block and controls axial movement. You need it to maintain correct endplay, protect the main bearings, and stop “crank walk.” It stabilizes clutch engagement, keeps the timing and oil pump drive happy, and reduces vibration. Replacing a worn set restores smooth shifting and long engine life.

How it works ⚙️

Two semi‑circular metal washers sit at the center main journal. With a steel back and low‑friction overlay, they ride on an oil film and absorb axial loads from the clutch/torque converter and accessory belt. Micro‑grooves spread oil evenly, while precise thickness brings endplay back to factory spec, preventing the crank from rubbing the block or seals.

What happens if it’s damaged ❗

Excess endplay leads to knocking when pressing the clutch, harsh shifts, moving crank pulley, metallic glitter in oil, erratic crank sensor signals, rear main seal leaks, and worn oil pump gears. Severe wear can cause crankwalk, flywheel contact, and catastrophic engine failure. Replace at the first signs and check endplay during clutch or bottom‑end service.

Pro tips

Install on clean journals, lube faces, torque mains to spec, and verify endplay with a dial indicator (typical range ~0.07–0.30 mm). Always change oil and filter after bearing work.
