STD Size Main Crankshaft Bearing
,Upper Shell Main Bearing Shell
,4DE1-1D Engine Upper Main Bearing
Upper Main Crankshaft Bearing Shell 1002015FE010XZ — STD Size OEM replacement for JAC N56, JAC Sunray, and SOLLERS Atlant models equipped with the 4DE1-1D (2.7L diesel) engine. Pair with lower bearing shell 1002016FE010XZ.
The Main Crankshaft Bearing with OEM number 1002015FE010XZ is a verified direct-fit upper bearing shell. It is installed in the cylinder block saddle and, together with the matching lower bearing shell, supports the crankshaft main journals — maintaining stable alignment and minimal rotational friction.
- ✓OEM Application Confirmed: 1002015FE010XZ is consistently listed across Russian and international suppliers as the upper main bearing for JAC N56 / Sunray / SOLLERS Atlant with the 4DE1-1D engine.
- ✓Engine Code Confirmed: 4DE1-1D (2.7D) — cross-referenced across multiple supplier databases.
- ✓Size Verified: Standard (STD / Nominal) — confirmed by supplier specification.
- ✓Material: Steel backing with precision anti-friction coating — confirmed by supplier description.
- ✓Pairing Requirement: Must be installed with lower bearing 1002016FE010XZ (sold separately or as a set).
Replace the bearing promptly if any of the following signs are present:
- Low oil pressure warning, or gauge reading below specification
- Knocking or deep metallic noise from the lower engine block, especially at idle or under load
- Visible scoring, flaking, or wear on old bearing shells during teardown
- Crankshaft journal damage or excessive clearance measured with plastigauge
- Engine seizure risk if bearing wear is ignored

- Engine removed and completely disassembled; crankshaft removed.
- Measure crankshaft main journals with a micrometer — STD bearings only fit journals within nominal specification. Ground crankshafts require oversize bearings.
- Clean block saddles and bearing shells thoroughly — any debris causes premature failure.
- Install upper shells (1002015FE010XZ) into block saddles, aligning oil holes and centering tabs.
- Install lower shells (1002016FE010XZ) into main caps.
- Lubricate bearing surfaces with clean engine oil or assembly lube.
- Install crankshaft carefully; install main caps in the correct order and orientation.
- Torque main cap bolts in the specified sequence to workshop manual specification.
- Measure oil clearance with plastigauge or bore gauge for each main bearing.
- Verify the crankshaft rotates smoothly by hand before final assembly.
- Main bearings are not a scheduled replacement item; replace during engine overhaul or upon bearing failure.
- Oil and filter: every 8,000–10,000 km (critical for the 4DE1-1D Common Rail engine).
- Oil pressure: monitor regularly; low pressure or knocking indicates bearing wear.
- Crankshaft journal inspection: at every major engine service.
- Packaging: Neutral bag/box; custom packaging available.
- Suitable for: JAC parts distributors, engine rebuild shops, and fleet maintenance suppliers.
- Note: Sold per piece. A full engine requires 5 upper + 5 lower bearings.
