OEM 800167137 The XCMG 4924731 Spring 800167137 is a genuine OEM valve spring engineered to control valve motion and maintain proper sealing in XCMG hydraulic excavator diesel engines.
Registered under part number 800167137, this valve spring returns the intake and exhaust valves to their closed position after each camshaft cycle.
The spring is wound from high-carbon spring steel wire, heat-treated for consistent stiffness, and finished with an anti-corrosion coating that resists heat and oil degradation.
Identical OEM free length, coil diameter and spring rate mean the valve spring installs directly during repair, with no shims or adapters required.
By holding the valve firmly against its seat, this spring protects combustion sealing, prevents valve float and keeps engine power stable under load.
The 800167137 valve spring is wound from high-carbon spring steel wire that resists fatigue, sag and load loss under continuous cycling.
Shot-peening and anti-corrosion coating improve surface durability, shielding the spring from rust, heat and oil degradation.
Identical OEM free length, coil diameter and spring rate allow a direct replacement without shims, which means faster installation.
Precise seat and open pressures hold the valve firmly closed and open at the correct lift, protecting combustion sealing and power output.
A stable spring rate prevents valve float at high rpm, keeping the engine running smoothly under the most demanding load conditions.
Because this is a genuine XCMG component, it preserves warranty coverage and maintains full compatibility with other OEM parts.
Production begins with certified spring steel wire that is inspected for diameter, tensile strength and surface quality before release.
Coiling is performed on computer-controlled machines that hold free length, coil diameter and end-squareness within exact tolerances.
After coiling, each spring is heat-treated, shot-peened and coated, then inspected for cracks, surface defects and dimensional accuracy.
Batch records allow XCMG to trace every 800167137 valve spring back to its raw material lots, so any quality question can be answered quickly.
Sample springs from each production batch undergo load testing, fatigue testing and heat aging to confirm long-term durability and stable spring rate.
The valve spring closes the intake and exhaust valves after each camshaft cycle, sealing the combustion chamber against compression and exhaust pressure.
The 800167137 spring maintains consistent seat pressure at both low idle and full load, keeping combustion sealing stable and reliable.
Stable valve sealing protects the engine from compression loss, misfire, power derating and excessive fuel consumption.
By preventing valve float, the spring also protects the valve train from piston-to-valve contact and catastrophic engine damage.
When the valve spring performs correctly, the engine holds compression and the machine experiences less vibration and stress.
Inspect the valve spring during routine engine service for cracks, sag or surface damage, and replace any worn unit with a genuine 800167137 spring.
The 800167137 valve spring installs with standard engine repair tools, which keeps downtime and labour costs low during overhaul work.
Park the excavator on firm level ground, shut down the engine, and allow the system to cool before starting work.
Remove the cylinder head cover, inspect the valve train, and use a valve spring compressor to remove the retainer and old spring.
Position the new valve spring, install the retainer, and release the compressor, ensuring the spring seats correctly on the cylinder head.
Check that the spring is square, the retainer is fully seated, and the valve moves freely through its full lift range.
Start the engine at low idle, listen for abnormal noise, check compression, and confirm correct performance before returning the machine to service.
Choosing the genuine 800167137 valve spring pays back over time by preventing compression loss and engine damage.
A weak or broken valve spring causes misfire, power loss and valve-to-piston contact, which lead to costly engine repairs.
The durable spring steel construction of this valve spring keeps seat pressure consistent over a long service life, reducing replacement frequency.
Reliable valve sealing also extends the life of connected parts such as the camshaft, valves, guides and piston rings.
Field data from large construction and mining fleets shows genuine XCMG engine components reduce valve train-related downtime significantly.
The spring remains serviceable for years under normal conditions, removing the need for premature replacement and lowering inventory costs.
XCMG applies sustainable manufacturing principles to the 800167137 valve spring through recyclable steel content and energy-efficient processes.
Extended service life, often exceeding 10,000 hours in normal conditions, cuts material waste and lowers the environmental footprint.
Efficient combustion also reduces fuel consumption and exhaust emissions, which supports regulatory compliance and responsible site management.
Materials used in this valve spring are free from restricted substances and comply with RoHS and REACH rules for safe handling and disposal.
Selecting genuine XCMG engine 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 800167137 valve spring is stocked in XCMG regional distribution centres across North America, Europe, Asia and Australia.
Every unit is wrapped with protective film inside a fitted carton, shielding the spring from impact, moisture and contamination 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 spring until installation, preventing damage that often occurs 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 800167137 valve spring comes from an ISO 9001 and ISO 14001 certified plant with full traceability from raw stock to packed product.
Incoming spring steel wire is tested for chemical composition, tensile strength and diameter accuracy before release to production lines.
During manufacturing, free length, coil diameter, wire diameter and end-squareness are monitored continuously by trained operators.
Post-production checks include load testing, hardness testing and dimensional verification to confirm that each spring meets specification.
Sample springs from each batch undergo fatigue testing and heat aging to prove long-term durability and stable spring rate.
Only springs that pass every quality gate are released, so you receive a dependable, high-performance engine component every time you order.
Cheap aftermarket valve springs often use low-grade wire, poor heat treatment or inaccurate dimensions that lead to premature sag and failure.
Those shortcuts create valve float, compression loss and valve-to-piston contact in demanding construction and mining conditions.
The genuine 800167137 is built to exacting XCMG standards, delivering correct fit, stable seat pressure and durable performance on site.
Its robust spring steel construction and precise manufacturing give consistent results, lowering the chance of expensive engine failures and downtime.
