The genuine 860113158 connecting rod bearing features a tri-metal construction: steel backing for structural strength, a nickel barrier to prevent diffusion, and an aluminum-tin (AlSn20Cu) overlay for low friction and high conformability. This design ensures excellent embeddability for foreign particles, preventing crankshaft journal scoring.
Each bearing half is precision machined to a wall thickness tolerance of ±0.005 mm, ensuring consistent oil clearance across all cylinders. The bearing’s surface is micro-polished to Ra 0.15–0.25 μm, promoting rapid oil film formation during cold starts. XCMG’s quality control includes 100% inspection of crush height and eccentricity.
The 860113158 bearing is designed to provide an oil clearance of 0.045–0.075 mm when installed with proper torque. This tight tolerance reduces oil leakage and maintains hydrodynamic pressure, preventing metal-to-metal contact even under peak combustion loads. The bearing’s axial grooves distribute oil evenly across the journal surface.
In field tests on GR2003 graders, engines rebuilt with genuine 860113158 bearings showed 20% lower oil temperature and 30% longer bearing life compared to aftermarket alternatives. The aluminum-tin alloy also resists corrosion from acidic combustion byproducts, extending service intervals.
The 860113158 bearing has been validated to 200 million load cycles at 80 MPa specific pressure without fatigue failure. The steel backing provides high strength, while the soft overlay prevents seizure during momentary oil starvation. XCMG’s accelerated engine testing shows bearing life exceeding 12,000 hours in normal grader operation.
Aftermarket bearings often use lower-grade alloys that fatigue quickly, leading to bearing spin or knock. Genuine XCMG bearings are manufactured in an IATF 16949 facility, with 100% ultrasonic testing for bond integrity. Choose 860113158 for reliability.
Before installing the 860113158 bearing, clean the connecting rod and cap thoroughly. Lubricate the bearing back and the rod bore with engine oil. Insert the bearing halves into the rod and cap, ensuring the locating tang engages with the notch. Do not file or modify the bearing.
Torque the connecting rod bolts in two stages: Stage 1: 50 Nm, Stage 2: 90° rotation (angle tightening). Use new bolts each time. After torquing, verify that the crankshaft rotates freely. Measure oil clearance using plastigage – acceptable range 0.045–0.075 mm. If clearance exceeds 0.10 mm, replace bearings.
Counterfeit connecting rod bearings often use plain aluminum without steel backing, leading to rapid wear and spinning. Some have incorrect crush height, causing the bearing to move or seize. Genuine 860113158 bearings are precision-ground to exact XCMG specifications and include a lead-free overlay, meeting environmental standards.
Using OEM bearings preserves engine warranty and ensures correct oil clearance. The 860113158 also features a tin flash coating to prevent rust. Don’t risk engine seizure – invest in genuine XCMG quality.
Steel-backed design, withstands 80 MPa load.
0.045–0.075 mm oil clearance for optimal lubrication.
12,000+ hours tested in motor grader engines.
Symptoms of worn connecting rod bearings include a deep knocking noise (especially under load), low oil pressure, and metallic debris in the oil filter. To diagnose, perform an oil pressure test – if pressure drops more than 15% from specification, bearings may be worn. Remove the oil pan and inspect bearings for scoring or fatigue.
When replacing bearings, always measure the crankshaft journal for taper and out-of-round. Service limit: taper 0.01 mm, out-of-round 0.005 mm. If exceeded, the crankshaft must be ground and undersize bearings used. XCMG offers undersize bearings (0.25 mm, 0.50 mm) for reground crankshafts – order separately.
Store spare 860113158 bearings in original packaging, flat, away from moisture. Shelf life is 5 years. Before installation, verify the part number and cleanliness. Do not touch the bearing surface with bare hands – oils and contaminants can affect performance.
