OEM 318602639 The XCMG Motor Mount Assembly 318602639 is a genuine OEM engine mounting assembly built to hold the diesel engine securely on XCMG hydraulic excavators.
Identified by the OEM number 318602639, this motor mount assembly keeps the engine in correct alignment and separates engine vibration from the machine frame.
It combines high-strength steel brackets with heavy-duty rubber isolators that absorb shock, cut noise and resist oil, heat and weathering.
Exact OEM mounting hole spacing, bracket angles and rubber hardness deliver a direct replacement that needs no modification during installation.
By locking the engine firmly in place, this assembly prevents misalignment, protects the drivetrain and extends the working life of the whole machine.
The 318602639 Motor Mount Assembly uses heavy-duty rubber isolators that soak up engine vibration and lower noise levels inside the operator cab.
Its high-strength steel brackets hold the engine firmly in correct alignment, preventing movement that would otherwise stress the drivetrain.
Exact OEM hole spacing, bracket angles and rubber hardness allow a direct replacement without modification, so the part fits right the first time.
The rubber compound resists oil, heat and weathering, keeping damping performance consistent across thousands of operating hours.
An anti-corrosion coating protects the steel brackets from rust and chemical attack, extending service life in harsh job site environments.
Because the assembly is a complete set, technicians replace worn mounts in one operation instead of ordering separate brackets and isolators.
Production begins with certified steel plate and rubber compounds that are checked for hardness, strength and oil resistance before release.
Brackets are cut, formed and welded on computer-controlled machines that hold dimensions, angles and hole positions to exact tolerances.
Rubber isolators are moulded to the specified hardness and bonded or mechanically fastened to the brackets for secure, long-term operation.
After assembly, every mount is inspected for dimensions, weld quality, rubber bond integrity and coating thickness before packing.
Batch records let XCMG trace each 318602639 mount back to its raw material lots, so any quality issue can be found and corrected quickly.
A motor mount assembly secures the engine to the machine frame and isolates the vibration that would otherwise damage surrounding components.
The 318602639 mount maintains stable engine alignment at both low and high engine speeds, keeping the drivetrain running smoothly.
Stable alignment protects the flywheel, coupling and transmission from shock loads, reducing the risk of premature component failure.
By absorbing vibration, the mount also reduces noise and operator fatigue, which improves comfort and concentration during long shifts.
When the mount works correctly, the engine stays in place and the machine frame experiences far less stress, cracking and weld fatigue.
Inspect the mount regularly for cracks, rubber degradation or loose bolts, and replace any worn unit with a genuine 318602639 motor mount assembly.
The 318602639 Motor Mount Assembly installs with standard hand tools, which keeps downtime and labour costs low during scheduled servicing.
Park the excavator on firm level ground, lower the attachment, shut down the engine and support the engine with a crane or jack.
Remove the old mount, inspect the frame and engine mounting points for wear or damage, then clean the mating surfaces thoroughly.
Fit the new mount into position, align the bolt holes, and install the mounting bolts by hand before tightening to the specified torque.
Lower the engine onto the new mount, confirm that it sits correctly, and tighten all bolts evenly to the correct torque value.
Start the engine at low idle, check for unusual noise or vibration, and run through full function cycles before returning the machine to work.
During routine service, check bolt torque values and inspect the rubber isolators for cracking, swelling or oil contamination.
Choosing the genuine 318602639 Motor Mount Assembly pays back over time by preventing engine misalignment and reducing unplanned downtime.
A failed mount can allow the engine to shift, causing drivetrain damage, excessive vibration and costly repair work on site.
The durable construction of this mount keeps damping performance consistent over a long service life, cutting replacement frequency.
Reliable isolation also extends the life of connected parts such as the flywheel, coupling, transmission and machine frame.
Field data from large construction and mining fleets shows genuine XCMG mounting components reduce vibration-related downtime significantly.
The assembly remains serviceable for years under normal operating conditions, removing the need for premature replacement and lowering inventory costs.
XCMG applies sustainable manufacturing principles to the 318602639 mount using recyclable steel and rubber content and energy-efficient processes.
The extended service life, often beyond 10,000 hours in normal conditions, reduces material waste and lowers the environmental footprint.
Preventing engine misalignment also avoids secondary damage and fluid leaks, which supports regulatory compliance and responsible site management.
Steel and rubber materials are free from restricted substances and comply with RoHS and REACH rules for safe handling and disposal.
Selecting genuine XCMG mounting components supports responsible equipment management while delivering superior operational reliability.
The precision-engineered design allows long, dependable service, which minimises resource consumption across the working life of the machine.
The 318602639 Motor Mount Assembly is stocked in XCMG regional distribution centres across North America, Europe, Asia and Australia.
Every unit is packed with protective wrap inside a fitted carton, shielding it from impact, moisture and dust during transit.
For fleet-wide orders, XCMG offers volume pricing and consolidated freight options that reduce procurement costs and simplify inventory planning.
Real-time stock visibility and dedicated supply chain support help fulfil urgent requests quickly, shortening downtime and keeping excavators productive.
Sturdy packaging preserves the factory condition of the assembly until installation, preventing damage that can occur with poorly stored spare parts.
With the XCMG global aftermarket network behind it, you can depend on consistent quality and availability to keep your fleet at full capacity.
Every 318602639 Motor Mount Assembly comes from an ISO 9001 and ISO 14001 certified plant with full material traceability from raw stock to packed product.
Incoming steel plate and rubber compounds are tested for tensile strength, hardness and oil resistance before release to production lines.
During manufacturing, bracket dimensions, weld quality, rubber hardness and coating thickness are monitored continuously by trained operators.
Post-production checks include dimensional verification, load testing and vibration testing to confirm each mount meets its specification.
Sample mounts from each batch undergo endurance cycling and thermal cycling to prove long-term durability and stable damping performance.
Only mounts that pass every quality gate are released, so you receive a dependable, high-performance engine mounting component every time.
Cheap aftermarket mounts often use lower-grade steel, softer rubber or inaccurate dimensions that lead to rapid failure and heavy vibration.
Those shortcuts lead to engine misalignment, drivetrain damage and poor reliability in demanding construction and mining conditions.
The genuine 318602639 is built to exacting XCMG standards, delivering correct fit, reliable damping and durable performance in the field.
Its robust brackets and high-quality rubber provide consistent results, lowering the chance of expensive engine failures and machine downtime.
