Cummins ISDe/QSB6.7 connecting rod bearing set (OEM: 4893637) with high-load trimetal overlay.
Prevents bearing spin-out in industrial applications. Fits equipment including Dongfeng Kinland trucks, Komatsu PC200-8, and Sany SY215C excavators.
In stock for global wholesale export.
Maintaining oil pressure and reducing friction in high-output common rail engines requires precision components. Our Cummins ISDe rod bearing sets are engineered to withstand the extreme firing pressures of the 6.7L and 4.5L platforms. Designed as a direct replacement for OEM 4893637, these bearings are critical for preventing spin-outs in heavy-duty excavators like the Komatsu PC200-8 and Dongfeng commercial trucks.
Ruich Value utilizes advanced tri-metal sintering technology to match the durability standards of the original DCEC components. Whether you are rebuilding a QSB6.7 for a construction site or servicing a fleet of ISBe-powered buses, our bearings offer the verified dimensional accuracy and load capacity needed for reliable aftermarket performance.

A1: Symptom: Engine “knocking,” drop in oil pressure, or metal shards in oil. Diagnosis: In construction machines like the Komatsu PC200-8, extreme load cycles and potential dust contamination in the oil system can break the thin oil film, leading to premature bearing shell “spin-out.” Solution: Our 4893637 trimetal bearings provide a thick, load-bearing copper-lead layer that resists deformation under the intense cylinder pressure of the 6.7L engine.
A2: Technical Detail: Rod caps must be torqued to factory ISDe/QSB specifications with torque-angle sequence verified. Pro-Tip: Always measure the journal clearance using Plastigage. If the journal is worn down by even 0.02mm, standard 4893637 bearings will not hold oil pressure, leading to total bearing failure shortly after startup.
A3: Diagnosis: Bimetal bearings often cannot handle the torque-to-power ratio of modern common rail engines. Our Solution: The trimetal design (steel/copper-lead/babbitt) gives the bearing the structural hardness to carry the load while maintaining enough softness to “embed” minor contaminants, protecting your 6.7L engine’s crankshaft in demanding field conditions.
