The 860124360 Retaining Ring For Shaft (size 40×1.75 mm to DIN 471) is a genuine XCMG external circlip designed for motor grader axle shafts, gear assemblies, bearing retention, and transmission components.
This precision‑formed retaining ring secures components onto a 40 mm diameter shaft, preventing axial movement while allowing rotation.
Manufactured from high‑carbon spring steel with a corrosion‑resistant black oxide or zinc‑phosphated finish, the 860124360 withstands high rotational speeds, vibration, and shock loads on XCMG GR135 through GR350 motor graders.
A missing, cracked, or weakened retaining ring can allow bearings or gears to slide off the shaft, causing catastrophic failure of the final drive, transmission, or wheel hub.
Replacing a worn or lost circlip with the genuine XCMG 860124360 restores proper axial retention and prevents expensive drivetrain damage.
The 860124360 conforms exactly to DIN 471 specifications: it has a nominal shaft diameter of 40 mm, a wire thickness of 1.75 mm, and a gap that allows installation with standard circlip pliers.
Its tapered cross‑section ensures the ring seats firmly into the machined groove on the shaft, providing reliable axial location even under extreme vibration.
Common applications on GR graders include retaining the planetary gear carrier in the final drive, securing bearings on the tandem drive axles, and holding gears in the transmission countershaft.
Using genuine XCMG 860124360 guarantees correct material hardness, edge break, and gap dimensions – critical for safe and long‑lasting retention.
Never reuse a circlip that has been removed, as spring tension is lost. Always install a new genuine XCMG retaining ring during any bearing or gear replacement.
The 860124360 is made from C67S or SAE 1075 spring steel, heat‑treated to 44‑51 HRC for optimal elasticity and strength.

The XCMG 860124360 Retaining Ring is a small but mission‑critical component that prevents bearings, gears, and other components from sliding axially off shafts.
In the grader’s final drive, this ring holds the planetary gear bearings in place against the hub. If it fails, gears can shift, leading to metal‑to‑metal contact and complete drivetrain seizure.
On the tandem drive axle, the 860124360 secures the wheel bearings onto the spindle. A broken or missing ring allows the wheel to slide outward, destroying seals and causing rapid bearing failure.
Inside the transmission, similar retaining rings hold countershaft bearings and synchronizer assemblies. The 860124360 replaces worn rings that have lost tension or show cracks.
Without a properly seated circlip, axial play increases, causing vibration, noise, and eventual component walk‑out. The 860124360 ensures precise axial location even under high shock loads from ripping and dozing.
XCMG engineers specify this ring for all 40 mm shaft applications where heavy side loads exist. Its taper‑ground edges ensure full contact with the groove flank, maximizing retention force.
Each 860124360 retaining ring is produced from cold‑rolled C67S spring steel strip, precision stamped to DIN 471 tolerances.
After stamping, the rings are deburred in a tumbling process to remove sharp edges that could damage shafts or installer hands.
The rings then undergo a heat treatment process: austenitizing, oil quenching, and tempering to achieve 44‑51 HRC.
This hardness provides the perfect balance of elasticity (to open during installation) and strength (to resist permanent deformation under load).
A black oxide or zinc‑phosphate coating is applied, followed by a light oil dip to provide corrosion resistance up to 240 hours salt spray.
XCMG’s quality control includes 100% visual inspection for cracks, dimensional checks using go/no‑go gauges, and sample proof‑load testing.
Every genuine 860124360 is laser‑marked with the XCMG logo and part number for traceability.
Counterfeit rings often use low‑carbon steel that deforms permanently after the first removal, or they lack proper heat treatment, leading to breakage.
Only genuine XCMG rings guarantee the exact gap dimension, edge break geometry, and spring constant required for safe shaft retention.
Installing a new 860124360 retaining ring requires the correct external circlip pliers with 1.8 mm diameter tips.
Before installation, inspect the shaft groove for burrs, wear, or corrosion. Clean the groove with a wire brush and degreaser.
Compress the ring using pliers, then slide it over the shaft end and into the groove. Ensure the ring fully snaps into the groove – it should spin freely but not lift out.
Never reuse a circlip that has been removed; the expansion and contraction permanently reduce its clamping force.
After installation, check that the ring sits flush against the groove’s thrust face. If gaps are visible, the ring may be incorrect or the groove damaged.
For the final drive or wheel hub, always replace the retaining ring whenever you replace bearings inside that assembly.
XCMG recommends keeping a supply of 860124360 rings in your parts cabinet for all planned overhauls.
Never attempt to weld or repair a cracked ring – only genuine replacement guarantees safety and reliability.
Aftermarket retaining rings often have inconsistent cross‑section thickness, causing poor fit in the groove and reduced retention force.
Many generic circlips are made from soft, unhardened steel that bends open permanently under load, allowing components to slide off.
Counterfeit rings may also have sharp, untumbled edges that cut into the shaft groove, creating stress risers that can lead to shaft cracking.
The genuine XCMG 860124360 is manufactured to exact DIN 471 dimensions with a smooth, consistent taper and uniform gap.
Its heat treatment ensures it can be expanded repeatedly (during assembly) without taking a permanent set, yet retains full clamping force once installed.
Using genuine XCMG also simplifies warranty claims – dealers recognize authentic parts and cover defects for 12 months.
For fleet managers, the extra cost of genuine rings is negligible compared to the downtime and damage a failed aftermarket ring can cause.
Protect your grader’s drivetrain – insist on XCMG genuine 860124360 retaining rings.
Signs that the 860124360 retaining ring needs replacement include: visible cracking or notches, a loose fit in the groove (ring spins without resistance), or evidence of rust pitting.
If the ring can be removed by hand without pliers, it has lost its spring tension and must be replaced.
During routine axle or transmission service, always install a new ring – never reuse the old one even if it looks fine.
Preventive replacement is recommended every 5,000 operating hours or whenever the associated bearing or gear is replaced.
The cost of a genuine 860124360 ring is minimal compared to the cost of a final drive rebuild after a bearing walks off the shaft.
Keep a stock of at least five rings in your parts inventory – they are often needed during unplanned axle seal repairs.
During installation, always wear safety glasses – compressed rings can fly off if pliers slip.
A properly retained shaft component is a quiet, efficient component. Replace suspect rings immediately.
