1002015FB040PK Crankshaft Main Bearing is a sliding bearing shell set installed between crankshaft main journal and cylinder block of JAC HFC4DB2-1D diesel engine. It bears alternating impact loads generated during combustion and maintains stable lubricating oil film to prevent direct metal contact between crankshaft and engine block. This aftermarket replacement bearing set solves abnormal knocking noise from engine bottom, low oil pressure and journal scratching problems caused by alloy layer peeling, fatigue pitting and excessive clearance of worn bearings. Reliable lubrication protection prolongs crankshaft service life and avoids destructive engine faults for light trucks running frequent stop-and-go urban delivery and heavy-load transport tasks.
Product Advantages Steel base with high-performance bimetallic alloy layer, featuring strong load capacity and good embedability. Precision thickness control ensures consistent running clearance. Special surface oil distribution structure helps retain lubricant under impact load. Every bearing set passes thickness tolerance inspection and surface defect screening before shipment, OEM dimension supports direct replacement during engine overhaul.

FAQ
Q1: What symptoms indicate the main bearings are worn out?
A1: Heavy knocking sound from the lower engine block, idle oil pressure obviously lower than the standard range.
Q2: Why inspect crankshaft main journal before installing new main bearings?
A2: If the journal surface has scratches or out-of-round deformation, the new bearings will fail rapidly.
Q3: What risk will insufficient lubrication bring?
A3: Lubricating oil film breaks, resulting in bearing seizure and permanent damage to crankshaft and cylinder block.
