Installation Note: Align oil holes; torque rod bolts to manufacturer's standard.
Working Condition: Handles engine vibration, high pressure; works with all standard engine oils.
This 330-1004022-H is a rod bearing for truck engines-super crucial part, let me tell you. It sits between the connecting rod and crankshaft, acting as a buffer. Without it, those two metal parts grind right against each other, wrecking the engine fast.
It also helps lubricate the area, keeping the crankshaft spinning smooth even when the engine's working hard-like hauling heavy loads up hills.
Fits the right truck engines perfect-same size and specs as the original, no mods needed.
The bearing's tri-metal: steel back, copper-lead alloy middle, tin-plated surface. Super tough, handles high temps and pressure under the hood.
The tin plating (0.005mm thick) is smooth, cuts friction, wears slow. The steel back keeps it from warping, even after years of use.
Pro tip: Always install it with clean hands-no dirt or debris.
Even a tiny speck can scratch the crankshaft or bearing, leading to early failure.
Also, torque the connecting rod bolts to the engine's spec-too loose, it rattles; too tight, it squeezes the bearing and overheats.
Install's straightforward if you know engine work: take out the old one, line this up (match the oil holes!), bolt back.
Every bearing gets checked for thickness and smoothness before shipping-no rough spots, no uneven edges.
If your old one's worn (you might hear engine knocking), this is a solid replacement.
Key Features：
Engine saver: Prevents metal-on-metal contact between connecting rod and crankshaft-saves you from big engine repairs.
Smooth operation: Tri-metal material and tin plating cut friction, keep crankshaft spinning easy.
Tough build: Steel back resists warping; copper-lead alloy handles high temps/pressure (up to 150°C under normal use).
Perfect fit: Matches original specs-no tweaks needed, just drop it in.
Long-lasting: Slow wear, works well even with frequent engine startups and heavy loads.
Application ：
Only fits specific truck engine models that use part number 330-1004022-H-common in heavy-duty trucks used for long-haul or construction.
Before you buy, double-check your engine's make and model, and the original bearing's part number.
Don't guess-wrong size bearing will ruin your crankshaft and connecting rod, and that's a costly fix.
Maintenance Recommendations
To keep this bearing (and your engine) in good shape:
Change engine oil and filter every 5,000 km (or as per your truck's manual)-dirty oil has metal shavings that scratch the bearing.
Check oil pressure regularly.
Low oil pressure means the bearing isn't getting enough lubrication-fix that right away, or the bearing will wear out fast.
If you hear a knocking noise from the engine (especially when accelerating), stop driving ASAP.
That's usually a sign the bearing's worn or loose-ignoring it will blow the engine.
Don't overload your truck beyond its capacity.
Too much load makes the engine work harder, putting extra stress on the rod bearing.
Quality Assurance ：
Every 330-1004022-H rod bearing goes through three checks before shipping: first, they test the material (make sure the tri-metal layers are bonded tight, no separation); then check the dimensions (thickness, inner/outer diameter match specs); finally, inspect the surface (no scratches, tin plating even).
It's just as reliable as the original part-you can trust it to protect your engine and keep your truck running strong.
