Chery J15 Crankshaft (Part No.: 480EJ-1005011)

Let’s keep it straightforward—this isn’t just a “metal shaft” in your Chery J15. It’s the engine’s “power converter” and backbone , a heavy-duty, precision-machined steel component bolted inside the J15’s 480EJ engine block (right at the bottom). Think of it as the engine’s “rotating heart”: it connects to the piston rods (the parts that move up and down when fuel burns) and turns their straight-line motion into the rotational power that spins the J15’s wheels. Its main jobs? Send power to the transmission (so your car moves), sync with other engine parts (like the timing belt pulley), and keep the engine running smoothly (thanks to built-in balance weights). Without it, your J15’s engine would just “bounce” instead of generating power—total immobility.

This crankshaft is exclusively made for Chery J15 models with the 480EJ engine—always confirm your VIN to be sure! It’s tailored to fit perfectly: its “necks” (the smooth sections that rest on bearings) match the 480EJ engine block’s size (no wobbling), its holes for piston rods align exactly (no forced fitting), and its balance weights are calibrated to the J15’s engine vibration (no shaky drives). Grab a generic crankshaft? You’ll run into disaster: it’ll vibrate violently, wear out bearings fast, or even crack the engine block—all costing thousands to fix.

Core Jobs: Turn Fuel Into Motion (And Keep It Smooth)

It’s the engine’s “workhorse”—here are 3 key things it does for your J15:

Convert motion to power: When fuel burns in the engine, pistons push down on the connecting rods. The crankshaft takes that up-and-down push and turns it into a spinning motion, which then goes to the transmission and wheels (this is what moves your car).
Sync engine parts: It has a small gear or pulley on one end that connects to the timing belt/chain. This keeps the crankshaft spinning in time with the camshaft (so valves open/close at the right moment—no misfires).
Reduce vibration: It has thick, metal “balance weights” sticking out from the main shaft. These counteract the shaking from pistons moving up and down, keeping the engine (and your J15’s cabin) quiet and steady.

This 480EJ-1005011 crankshaft only works for Chery J15 with the 480EJ engine—wrong fit = engine ruin:

Fits These Models: All Chery J15 variants powered by the 480EJ engine (matches journal sizes, balance weight design, and timing mount—confirm via VIN).
Won’t Fit These:

Chery J15 with other engines (e.g., 477F): Different journal sizes and balance weights—crankshaft won’t fit or causes extreme vibration.
Other Chery models (e.g., Tiggo 8, Arrizo 7): Their engine blocks are smaller/larger—this crankshaft is too big/small to mount.
Non-Chery vehicles: Even if it “looks similar,” journal spacing and balance design differ—will destroy bearings and engine block.

Installation & Maintenance (Pros Only—Precision Is Non-Negotiable!)

Installation: Certified Chery Technicians Mandatory

Installing this crankshaft needs factory-level precision—DIY will destroy your J15’s engine:

Engine teardown: Techs fully disassemble the engine block (remove pistons, bearings, old crankshaft) and clean all surfaces (oil residue ruins new parts).
Bearings prep: They install new, 480EJ-specific main bearings and connecting rod bearings (match the crankshaft’s journal size exactly).
Mount the crankshaft: They lower the new crankshaft into the block, align the journals with bearings, and torque the main cap bolts in a strict order (Chery’s specs—wrong order bends the crankshaft).
Balance & test: They use a machine to check the crankshaft’s balance (ensures no vibration) and rotate it by hand (confirms smooth movement). Then they reassemble the engine, add oil, and test-run to check for leaks or noise.

Maintenance: Keep It Running (Lubrication Is Key!)

Use Chery-approved oil only: Cheap or wrong-weight oil doesn’t lubricate journals properly (causes metal-on-metal wear—destroys the crankshaft).
Change oil on time: Follow J15’s oil change schedule (usually every 5,000–7,500 km). Old oil has debris that scratches journals.
Check for oil leaks: If you see oil under the J15’s engine, the crankshaft’s front/rear seals might be bad—fix fast (low oil ruins bearings).
Never run the engine low on oil: Even 5 minutes of low oil starves journals of lubrication—causes permanent damage to the crankshaft.

Summary: Chery J15 Crankshaft (480EJ-1005011)

Exclusive to Chery J15 with the 480EJ engine (confirm via VIN), this steel crankshaft turns pistons’ up-down motion into rotational power (to drive the wheels). It also syncs with engine parts (like the timing belt pulley) and cuts vibration using built-in balance weights.

It won’t fit J15 with other engines, other Chery models (e.g., Tiggo 8), or non-Chery cars. Maintain by using Chery-approved oil, changing oil on schedule, and checking for leaks. Only the original avoids wear and engine damage.
