OEM 860687307 The XCMG Shock Absorber Block 860687307 is a genuine elastomeric damper that isolates vibration and absorbs shock between mounted components on XCMG hydraulic excavators.
Issued under the official part number 860687307, the block gives the technician a correctly sized damper that matches the mounting holes, bolt spacing and compression height it is designed for.
The rubber body and bonded steel plates are molded to the XCMG drawing, so the outline, hole centers and plate thickness fit the bracket without shims or slotting.
A matched compound and wall thickness absorb impact and cut vibration, so the mounted part does not hammer its bracket or crack nearby welds.
The compound resists oil, water and UV light, so the block does not harden, crack or separate from its plates in outdoor service.
Every unit is checked for block height, hole spacing, plate bond and hardness before the batch is packed for shipment.
Fitted to cab mounts, engine mounts, pump brackets and panel supports, this shock absorber block keeps the machine quieter and protects the structure from fatigue.
The 860687307 block is produced to the XCMG drawing, so the hole spacing and block height fit the bracket on the first attempt.
A matched compound and wall thickness absorb shock, so the mounted part does not hammer its bracket or crack nearby welds.
Bonded steel plates spread the bolt load, so the rubber does not tear away from the plates under vibration and torque.
The compound resists oil, water and UV light, so the block does not harden, crack or crumble in outdoor service.
Because the part matches the OEM number, a fitter installs it straight from the bag without shims, spacers or extra bolts.
Correct hardness keeps the block springy under load, so it keeps damping vibration instead of flattening out.
A sound block also reduces cab noise and structural fatigue, which protects the operator and extends frame life.
Keeping spare blocks on the shelf shortens repair time, so a collapsed mount does not leave a component rattling.
Each lot begins with certified rubber compound and steel plate tested for hardness, bond strength and corrosion resistance before molding.
Blocks are molded in controlled tooling, so the outline, hole pattern and rubber wall thickness stay uniform from batch to batch.
Trimming removes flash from the rubber edges, so the block seats flat and does not rock on a raised seam.
Inspectors measure block height, hole spacing, plate thickness and rubber hardness against a gauge made for this exact part number.
Batch records trace every 860687307 block to its compound lot and production run, so a quality question is settled quickly.
A shock absorber block sits between a mounted component and its bracket, so vibration and impact are absorbed before they reach the frame.
A hardened or collapsed block lets the component hammer the bracket, which cracks welds and loosens bolts over time.
The genuine 860687307 keeps the mount flexible, so the part stays isolated and the structure stays protected.
Correct fit avoids both a block that is too stiff and transmits vibration and one that is too soft and bottoms out.
A sound block protects the frame, cab and mounted components, which keeps service intervals predictable and extends machine life.
The 860687307 block is installed with a cleaning cloth, a spanner set and a torque wrench during body or component service work.
Support the mounted component, remove the old block and clean the bracket faces so no dirt or rust sits under the new part.
Check the bracket and plates for cracks, rust or distortion, since a damaged face will stop the block sitting flat.
Position the block, start the bolts by hand and confirm the holes align before tightening any fastener.
Tighten to the torque in the service data, so the block compresses evenly without tearing the rubber or crushing the plates.
Run the machine and check for rattles, movement or noise at the mount, then confirm the block has not shifted.
At service intervals, look for a cracked, collapsed or oil-soaked block and renew the part before the component rattles.
Every 860687307 block is produced in an ISO 9001 and ISO 14001 certified plant with traceability from compound to carton.
Incoming material is tested for hardness and bond strength, and finished blocks are gauged for height, hole spacing and plate thickness.
Each batch is screened for voids, cracks and bond defects, since these flaws let the block fail or separate from its plates.
Post-production checks include visual review, dimensional verification and a trial fit on the XCMG bracket fixture.
Sample blocks from each batch undergo compression, fatigue and salt spray tests to confirm damping and corrosion performance.
Cheap copies often use low-grade rubber or weak bonds, so the block hardens, cracks or tears away from its plates soon after installation.
A block with the wrong height or hardness can transmit vibration, bottom out under load or fail to fit the bracket holes.
The genuine 860687307 is made to the XCMG drawing, so height, holes, hardness and material match the original part.
Using genuine XCMG parts also preserves warranty coverage, protects resale value and keeps fit with OEM brackets.
Backed by XCMG global quality standards and technical support, this shock absorber block performs reliably in harsh conditions.
Choosing the genuine 860687307 block prevents a small vibration from turning into a cracked bracket or a broken weld.
A failed block lets the component hammer the frame, which loosens bolts and shortens the life of the structure.
A correctly made block holds its shape, so it does not need repeated replacement and does not flatten between services.
Reliable blocks also keep the cab quiet and the structure sound, which improves operator comfort and lowers ownership cost.
Service records from construction and mining fleets show genuine XCMG parts cut unplanned downtime.
XCMG produces the 860687307 block with efficient molding runs that keep production scrap low.
A long service life means fewer replacements, which lowers the material and energy tied to each block.
Damping vibration protects the frame, which keeps the machine usable for its full design life.
The materials in this part comply with RoHS and REACH requirements for safe handling and responsible recycling.
The 860687307 block is stocked in XCMG depots serving North America, Europe, Asia and Australia.
Each unit is bagged to protect the rubber and boxed in a strong carton that guards against dust, damp and crushing.
Fleet buyers can request volume pricing and combined freight, which simplifies planning and lowers landed cost.
Live stock data and responsive supply teams cover urgent requests fast, so machines return to work sooner.
Careful packing keeps the block uncompressed until fitting, avoiding the permanent set seen in loose storage.
