OEM 406.1000104-20, in 0.25 mm undersize, is designed for ZMZ-406 engines that have undergone crankshaft machining. These shells restore correct oil clearance and ensure smooth crankshaft-to-rod operation, making them essential for engine rebuilds and long-term reliability.\u003c\/p\u003e\n\u003cp data-start=\"704\" data-end=\"1078\"\u003e\u003cstrong data-start=\"704\" data-end=\"740\"\u003eWhy choose these bearing shells?\u003c\/strong\u003e\u003cbr data-start=\"740\" data-end=\"743\"\u003eDuring high-mileage use or after overheating, crankshaft journals often require regrinding. These OEM-spec 0.25 mm undersize shells provide precise fitment for reground cranks, maintaining proper lubrication and alignment. They ensure stable oil pressure, reduce friction, and extend the life of the ZMZ-406 engine under heavy loads.\u003c\/p\u003e\n\u003cp data-start=\"1080\" data-end=\"1304\"\u003e\u003cstrong data-start=\"1080\" data-end=\"1102\"\u003eTechnical details:\u003c\/strong\u003e\u003cbr data-start=\"1102\" data-end=\"1105\"\u003eOEM reference: 406.1000104-20\u003cbr data-start=\"1134\" data-end=\"1137\"\u003eSize: 0.25 mm undersize (repair size)\u003cbr data-start=\"1174\" data-end=\"1177\"\u003eMaterial: High-strength tri-metal bearing alloy\u003cbr data-start=\"1224\" data-end=\"1227\"\u003eApplication: Connecting rod bearing shells (set for 4 rods, matched halves)\u003c\/p\u003e\n\u003cp data-start=\"1306\" data-end=\"1395\"\u003e\u003cstrong data-start=\"1306\" data-end=\"1328\"\u003eCompatible models:\u003c\/strong\u003e\u003cbr data-start=\"1328\" data-end=\"1331\"\u003eBukhanka Modern (2.7L)\u003cbr data-start=\"1353\" data-end=\"1356\"\u003eHunter \u0026amp; 469 (2.7L)\u003cbr data-start=\"1375\" data-end=\"1378\"\u003ePatriot\u003cbr data-start=\"1385\" data-end=\"1388\"\u003eProfi\u003c\/p\u003e\n\u003cp data-start=\"1397\" data-end=\"1786\"\u003e\u003cstrong data-start=\"1397\" data-end=\"1419\"\u003eInstallation tips:\u003c\/strong\u003e\u003cbr data-start=\"1419\" data-end=\"1422\"\u003eThoroughly clean and polish crankshaft journals before installation. Use plastigauge to confirm oil clearance (~0.025–0.04 mm). Apply assembly lube or fresh engine oil to bearing surfaces before fitting. Install with correct orientation, align oil holes, and torque rod caps gradually to specification. Rotate the crankshaft by hand to check for smooth movement.\u003c\/p\u003e\n\u003cp data-start=\"1788\" data-end=\"2114\"\u003e\u003cstrong data-start=\"1788\" data-end=\"1808\"\u003eWhen to replace?\u003c\/strong\u003e\u003cbr data-start=\"1808\" data-end=\"1811\"\u003eReplace these shells during rebuilds whenever crankshaft journals are reground by 0.25 mm or if low oil pressure, bearing noise, or visible scoring occurs. They are a must-have in overhauls beyond 150,000 km. Fresh OEM bearings restore clearance, lubrication integrity, and overall engine reliability.\u003c\/p\u003e\n\u003cp data-start=\"2116\" data-end=\"2205\"\u003eNot sure if this part fits your vehicle?
