130418860102 Toyota BEARING SET, Price: 12.95$, Weight: 0.035kg

Crankshaft Main Bearing Set for Toyota Engines

This precision-matched set supports the crankshaft and maintains a stable oil film for smooth rotation, clean idle, and long engine life. Built from durable tri-metal shells with an anti-friction overlay, it restores factory clearances and quiets bottom-end noise. Perfect OE-fit solution for rebuilds or preventive maintenance.

Why it’s needed ⚙️

These bearings stop metal-to-metal contact between the crank and block. They center the crankshaft, cut friction, control heat, and help hold oil pressure. Use them when refreshing a high-mile engine, fixing low oil pressure, or curing cold-start knock.

How it works ️

Each half-shell locks into the block and cap to form a round bore. Pressurized oil creates a hydrodynamic wedge that floats the crank journal. Grooved mains route oil to each journal, while locating tabs and crush fit prevent spinning. Correct bearing grades set the right clearance for quiet, efficient running.

What happens if it’s worn or damaged

Expect knock under load, low oil pressure, metallic glitter in oil, rising temps, and rumble at idle. Ignored, a bearing can spin, starve the journal, score the crank, or seize—often leading to rod damage and a full rebuild.

Tech notes

Measure journals, choose proper grade, clean saddles, use assembly lube, torque caps in sequence, verify clearance with plastigage, and prime the oil system before first start.
