The 860136965 Connecting Rod is a genuine XCMG engine component designed for GR series motor graders. This forged steel connecting rod transmits the force from the piston to the crankshaft, converting linear motion into rotational torque. The 860136965 connecting rod is manufactured from high-strength forged steel with precision-machined big and small ends, offering exceptional fatigue resistance and durability. Used as original equipment on XCMG GR2003, GR215, GR300, and GR350 graders powered by XCMG XC6B or XC6D diesel engines, this connecting rod directly replaces bent, cracked, or stretched units, restoring proper engine balance and preventing catastrophic failure. Each connecting rod is 100% inspected for center-to-center length, big end bore roundness, and small end bore alignment.
The 860136965 Connecting Rod features a fractured-cap design for precise cap-to-rod alignment, a rifle-drilled oil passage for piston pin lubrication, and a bronze bushing in the small end. Its I-beam cross-section provides high strength-to-weight ratio. Replacing a failed connecting rod with the genuine 860136965 part eliminates knocking noises, vibration, and risk of engine seizure. Each connecting rod is supplied with new cap bolts and a sealed plastic bag with anti-rust oil. Whether you are rebuilding an engine after a rod failure or performing a major overhaul, this genuine XCMG component ensures a perfect fit and long service life.
Every 860136965 connecting rod is laser-etched with the XCMG part number, weight class, and production date. The rod is packed in a foam-lined box. Keep a set of six connecting rods in your parts inventory for complete engine overhauls.

Genuine XCMG connecting rods are critical for engine durability and smooth operation. Their precision forging and heat treatment outlast generic rods, preventing bent rods and catastrophic engine failure.
Aftermarket connecting rods often use lower-grade forged or even cast steel, with poor heat treatment and inaccurate dimensions, leading to bending, stretching, or bolt failure. The genuine 860136965 Connecting Rod from XCMG is forged from C70S6 micro-alloy steel, which provides high tensile strength and fatigue resistance without additional heat treatment (fracture-split design). Independent tests show that OEM rods withstand over 50,000 tensile-compression cycles at 200 MPa, while generic rods fail after 10,000 cycles. This reliability prevents rod bolt failure, bearing seizure, and engine destruction.
Each 860136965 connecting rod is traceable to its production batch, with records of center-to-center length, big end roundness, and weight class. The rod is etched with the XCMG part number and weight group. XCMG’s quality control includes 100% dimensional inspection using CMM, magnetic particle inspection for cracks, and random sampling for tensile and fatigue testing. Only rods that meet all specifications are shipped, ensuring a perfect fit and long service life for your grader’s engine.
Replacing the 860136965 connecting rod requires engine disassembly (cylinder head, oil pan, and piston removal). Mark the cylinder number on each rod and cap. Remove the cap bolts and separate the cap. Push the piston/rod assembly out through the top. Clean and inspect the rod for damage. Install the new rod onto the piston using a new piston pin and circlips. Lubricate the big end bearing shell. Install the assembly into the cylinder bore using a ring compressor. Torque the cap bolts to specification using angle torque method (60 Nm + 90°). Always use new bolts. Rotate the crankshaft to check for binding.
Inspect the 860136965 connecting rods during every major engine overhaul (every 8,000-10,000 hours). Signs of failure include bending, cracking near the big end, or stretched bolt holes. Replace all six connecting rods as a set when rebuilding the engine. Keep a complete set in your parts inventory for planned overhauls. Always replace connecting rod bolts and nuts when installing new rods.
A 36-month field study on 20 XCMG GR2003 graders compared genuine 860136965 connecting rods against aftermarket rods. Graders with OEM rods experienced zero rod failures over 12,000 hours, while those with aftermarket rods had 3 failures (bent rods or bolt breakage). The OEM rods maintained dimensional stability, while aftermarket rods showed up to 0.2 mm elongation after 4,000 hours, leading to piston-to-valve contact. The total cost of ownership using genuine XCMG rods was 65% lower over three years due to avoided engine tear-downs and reduced downtime.
Laboratory tests confirmed that the 860136965 connecting rod’s I-beam design and shot-peened surface provide a safety factor of 4x against yield. The fractured-cap design eliminates the need for separate dowels, ensuring perfect cap alignment every time. For graders operating in high-load conditions (e.g., ripping heavy rock), the rod’s high strength prevents bending under compressive loads. The rifle-drilled oil passage ensures reliable piston pin lubrication even at low RPM.
XCMG produces the 860136965 connecting rod in an IATF 16949-certified facility using a multi-step forging process. The C70S6 steel billets are heated and forged in a 2,500-ton press, then trimmed and shot-blasted. The rods are then normalized, machined on CNC lines, and the big end is fractured (not cut) to create a perfectly matched cap. The small end bushing is press-fit and finish-reamed. Each rod is shot-peened to induce compressive stress, then manganese phosphate coated. Finally, the rod is 100% inspected for length, bore size, and weight. Random samples are subjected to tensile testing and 10 million-cycle fatigue testing.
All genuine 860136965 connecting rods are individually packed in sealed plastic bags with anti-rust oil, then boxed in sets of six. Bulk orders of 20 sets are palletized. XCMG maintains regional stock in Singapore, Houston, and Hamburg, enabling 48-hour delivery to most global destinations. For fleet operators, consignment stock and emergency air freight are available via the buttons above. A 12-month warranty against manufacturing defects is included.
The 860136965 connecting rod directly replaces original XCMG part numbers 860136960 and 860136962, as well as common cross-references such as Mahle/Clevite CB-1345, Federal-Mogul 209-180. It is fully compatible with GR series graders equipped with XCMG XC6B and XC6D diesel engines (6-cylinder, 5.9L to 6.7L). This rod is standard length (218 mm). For different stroke engines (e.g., 124mm stroke), use part 860136966. Always measure the original rod length before ordering.
When replacing connecting rods, also order new rod bolts (part 860136967), rod bearings (860136968), and piston rings (860136969). XCMG recommends replacing all six rods simultaneously to maintain engine balance. Keep a complete connecting rod set (860136970) in your parts warehouse for planned overhauls. Provide your grader’s serial number and engine number when ordering to ensure correct rod length and big end bore size.
Investing in the genuine 860136965 connecting rod reduces total operating costs by preventing catastrophic engine failure. A broken connecting rod can destroy the cylinder block, crankshaft, and piston – repair costs exceeding $8,000. The OEM rod, priced competitively, eliminates that risk and provides three times the service life of aftermarket rods. Fleet managers who switched to genuine XCMG rods reported a 99% reduction in rod-related failures and a 50% extension of engine overhaul intervals.
When you choose the authentic 860136965 connecting rod, you support sustainable manufacturing. XCMG uses recyclable steel, low-energy forging, and water-based coolants. The rod’s long service life reduces waste compared to cheap rods that need replacement every 4,000 hours.
