1006011FE010 Camshaft HFC4DE1-1D DOHC Engine Camshaft for JAC N56 Sunray Atlant 2.7L Diesel

The camshaft with OEM number 1006011FE010 is a direct-fit replacement engine camshaft for JAC N56, Sunray, and Atlant vehicles equipped with the HFC4DE1-1D / 4DE1-1D (2.7L) diesel engine. It controls the opening and closing of the intake and exhaust valves — essential for efficient engine breathing and power delivery.

The camshaft rotates at half crankshaft speed, and its lobes actuate the valve lifters (or directly actuate valves in some DOHC designs) to open the intake and exhaust valves at precisely timed intervals. The HFC4DE1-1D engine uses a DOHC (Double Overhead Camshaft) valvetrain with 4 valves per cylinder. Correct cam lobe profile, journal diameter, and timing are critical for compression, emissions, and engine performance.

Replace the camshaft if any of the following symptoms are observed:

• Engine misfire or rough running (incorrect valve timing)
• Loss of power / poor acceleration
• Abnormal valvetrain noise (ticking, tapping)
• Visible wear or scoring on cam lobes or journals
• Check engine light (cam/crank correlation code)
• Excessive oil consumption (worn valve guides secondary to cam wear)

1. Remove timing cover and timing chain/belt. Note alignment marks.
2. Remove camshaft bearing caps in reverse sequence. Lift camshaft carefully.
3. Inspect bearing journals and lobes for wear. Check valve lifters/buckets.
4. Install new camshaft. Lubricate journals with assembly lube.
5. Torque bearing caps in stages per OEM sequence torque spec pending — verify against JAC manual.
6. Align timing marks precisely. Install timing chain/belt.
7. Adjust valve clearance if applicable. Rotate engine by hand to verify no interference.
8. Reassemble and run engine. Check for abnormal noise and timing codes.

The camshaft is not a routine replacement item. Inspect when valvetrain noise, performance loss, or timing codes appear. Oil changes at OEM intervals are critical for camshaft longevity. Replace if lobes or journals show measurable wear beyond OEM limits.
