The genuine XCMG Rubber Mounting Block with OEM number 332113067 is a premium vibration-damping component engineered for XCMG articulated dump trucks (AD series). This elastomeric mounting block isolates the cab, cooling modules, and hydraulic tanks from chassis-induced vibrations and shocks. The 332113067 Rubber Mounting Block significantly reduces noise, prevents fatigue cracking in sheet metal, and extends the service life of sensitive electronic and hydraulic components in extreme mining environments.
The XCMG Rubber Mounting Block 332113067 is designed to absorb shock and isolate structure-borne noise in AD-series articulated dump trucks. By decoupling the cab from chassis vibrations, it significantly reduces operator fatigue over long shifts, improving safety and productivity.
In mining applications, constant pounding from haul roads can crack aluminum fuel tanks and hydraulic reservoirs. The 332113067 mount blocks reduce peak accelerations by up to 70%, preventing fatigue failures.
Fleet data shows that trucks fitted with genuine XCMG rubber mounts experience 55% fewer cab sheet-metal cracks and 40% longer life for dashboard electronics compared to rigid-mounted or generic rubber blocks.
The 332113067 uses a specially formulated natural rubber compound with a Shore hardness of 55 A, balancing flexibility and load-bearing capacity. Anti-oxidants and UV stabilizers prevent cracking even after years of outdoor exposure.
Two internal steel plates are molded into the rubber, providing a rigid mounting interface while allowing controlled shear deflection. The plates are zinc-plated for corrosion resistance.
The compound resists swelling from hydraulic oil and diesel fuel, a common failure mode for inferior rubber mounts in engine compartments. In oil-immersion tests, swelling stays below 15% after 72 hours.
Replacing a worn rubber mounting block with the 332113067 is a straightforward task. Support the component (cab, radiator, etc.), remove the four M12 bolts, lift the component slightly, slide out the old block, and insert the new one. Torque to 70 Nm.
Because the mounting pattern is identical across AD45 through AD100 models, the same 332113067 block fits multiple applications: cab rear mounts, radiator lower supports, and hydraulic tank feet. This reduces spare parts SKUs.
For field repairs, no special tools are needed – only standard metric sockets. A complete set of four blocks (OEM 332113067-SET) includes mounting bolts and washers.
Without proper vibration isolation, repeated shocks cause metal fatigue in cab floor pans, radiator mounting ears, and fuel tank straps. Cracks in these components often require welding or expensive replacement. The 332113067 rubber block absorbs the energy before it reaches the sheet metal.
Additionally, by reducing transmitted vibration, electronic control modules and sensors experience fewer solder joint failures. A single cab controller replacement can cost $2,500 – the rubber block is a preventive investment.
Noise levels inside the cab are also noticeably lower: measurements show a 6–8 dBA reduction at the driver’s ear position, directly improving operator comfort and alertness over 12-hour shifts.
Aftermarket rubber blocks often use reclaimed rubber or incorrect compounds that harden rapidly under heat, losing their damping ability within months. Hardened mounts transmit vibrations almost as rigid mounts, defeating the purpose.
Some counterfeit blocks have insufficient steel reinforcement – the rubber can separate from the plates, causing sudden component sag or complete detachment. Genuine XCMG 332113067 blocks are bonded under high pressure and heat to ensure vulcanization.
Always inspect the block for the XCMG logo molded into the rubber and the part number stamped on the steel plates. The genuine block has a distinct black color with a slightly matte finish; counterfeits are often glossy or have visible bubbles.
Replacing a single rubber mounting block costs less than 0.5% of the value of the component it protects. For a fleet of 30 AD trucks, proactively replacing all mounts every 10,000 hours (approximately every two years) costs $3,000–$4,000 and prevents an estimated $50,000 in fatigue-related repairs.
Moreover, the reduced vibration extends the life of cab HVAC units, window seals, and instrumentation. Operators report fewer loose screws and rattles, improving perceived quality and resale value.
The block’s resistance to oil and ozone means it lasts the full service interval without hardening, unlike cheaper alternatives that require replacement every 2,000 hours.
Every XCMG Rubber Mounting Block 332113067 is manufactured under ISO 9001:2015 and IATF 16949 certified processes. Each block is 100% compression-tested to verify spring rate, and a sample from each batch undergoes dynamic fatigue testing (1,000,000 cycles at 5 Hz, 5 mm amplitude) with no visible cracks or separation.
XCMG also performs salt spray and ozone resistance testing (100 pphm, 40°C, 70 hours). The company provides a 24-month warranty against manufacturing defects, including delamination or abnormal hardening.
For extreme cold applications (Arctic mines), a low-temperature compound version (OEM 332113067-LT) with a service range down to -55°C is available. Consult XCMG parts for specialized variants.
