Crankshaft Main Bearings — Smooth, Quiet Power ⚙️

These precision engine bearings support the crank and keep every piston stroke silky and efficient. Built for OE-level fit in popular Toyota 4- and 6‑cylinder blocks, they stabilize the rotating assembly, protect journals, and hold correct oil pressure for long service life.

Why this part is needed ❗

Combustion loads try to push the crank into the block. The bearing shells spread that force and keep a controlled oil clearance. Without them in top condition, you get noise, heat, and rapid wear. They are essential in rebuilds, knock cures, and low-pressure fixes.

How it works ️

Steel-backed, tri-metal shells seat in the saddles and caps. An oil groove and feed holes supply a hydrodynamic film that centers the journal so metal never touches metal. Integrated thrust surfaces control endplay during shifts and accessory loads.

What happens if worn or broken

Symptoms include cold-start knock, copper tint on shells, glitter in oil, and low idle pressure. Ignored failures can spin a shell, wipe a journal, drop pressure to zero, overheat the crank, bend rods, or seize the engine.

Build & sizes

OE-spec geometry, anti-corrosion coating, and locating tangs. Available in standard and undersizes for reground cranks. Match clearances with plastigage and follow torque sequence.

Pro tips

Measure housing bores, verify 0.0015–0.0030 in clearance (engine-dependent), lube with assembly oil, check endplay, prime the pump, and change oil after break-in.
