OEM 800167156 The XCMG 4099227 Oil Pump Gear 800167156 is a genuine OEM gear engineered to drive the engine oil pump and maintain proper lubrication pressure in XCMG hydraulic excavators.
Registered under part number 800167156, this oil pump gear meshes with the mating drive gear to rotate the oil pump at the correct speed.
The gear is machined from high-strength alloy steel, heat-treated for wear resistance, and finished with precision-ground teeth for smooth, quiet operation.
Identical OEM tooth profile, bore diameter and keyway geometry mean the oil pump gear installs directly during repair, with no modification required.
By driving the oil pump reliably, this gear protects the engine from oil starvation, bearing wear and catastrophic failure under heavy load.
The 800167156 oil pump gear is machined from high-strength alloy steel that resists wear, pitting and tooth breakage under continuous load.
Carburizing and precision grinding produce a hard, smooth tooth surface that meshes quietly and maintains correct backlash.
Identical OEM tooth profile, bore diameter and keyway allow a direct replacement without modification, which means faster installation.
Precise tooth geometry ensures uniform load sharing, reducing noise, vibration and the risk of premature gear failure.
A durable anti-corrosion finish shields the gear from rust and oil degradation, extending service life in hot, dusty environments.
Because this is a genuine XCMG component, it preserves warranty coverage and maintains full compatibility with other OEM parts.
Production begins with certified alloy steel bar that is inspected for chemical composition, hardenability and grain structure before release.
Gear cutting is performed on computer-controlled hobbing machines that hold tooth profile, lead and index accuracy within exact tolerances.
After cutting, each gear is carburized, quenched and tempered, then ground to final tooth geometry and bore dimensions.
Batch records allow XCMG to trace every 800167156 oil pump gear back to its raw material lots, so any quality question can be answered quickly.
Sample gears from each production batch undergo hardness testing, tooth profile inspection and fatigue testing to confirm long-term durability.
The oil pump gear drives the oil pump, which circulates pressurized oil to the crankshaft, bearings, camshaft and turbocharger.
The 800167156 gear maintains correct pump speed at both low idle and full load, keeping oil pressure stable and lubrication continuous.
Stable oil pressure protects the engine from metal-to-metal contact, overheating and accelerated wear that shorten component life.
By preventing oil starvation, the gear also reduces the risk of turbocharger seizure, bearing failure and catastrophic engine damage.
When the oil pump gear performs correctly, the engine holds oil pressure and the machine experiences less vibration and stress.
Inspect the gear during routine engine service for tooth wear, pitting or cracks, and replace any worn unit with a genuine 800167156 gear.
The 800167156 oil pump gear 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 and drain before starting work.
Remove the oil pan or front cover as required, inspect the oil pump drive, and extract the old gear from its shaft.
Clean the shaft and keyway, position the new gear, align the key, and press or slide the gear into place without damaging the teeth.
Check gear backlash and tooth contact pattern, then reassemble the engine and refill with the correct oil specification.
Start the engine at low idle, check oil pressure, listen for abnormal noise, and confirm correct performance before returning the machine to service.
Choosing the genuine 800167156 oil pump gear pays back over time by preventing oil starvation and engine damage.
A worn or broken oil pump gear causes oil pressure loss, bearing seizure and turbocharger failure, which lead to costly engine repairs.
The durable alloy steel construction of this gear keeps tooth geometry consistent over a long service life, reducing replacement frequency.
Reliable oil pressure also extends the life of connected parts such as the crankshaft, bearings, camshaft, turbo and oil pump.
Field data from large construction and mining fleets shows genuine XCMG engine components reduce lubrication-related downtime significantly.
The gear remains serviceable for years under normal conditions, removing the need for premature replacement and lowering inventory costs.
XCMG applies sustainable manufacturing principles to the 800167156 oil pump gear 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 lubrication also reduces fuel consumption and exhaust emissions, which supports regulatory compliance and responsible site management.
Materials used in this oil pump gear 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 800167156 oil pump gear 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 gear 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 gear 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 800167156 oil pump gear comes from an ISO 9001 and ISO 14001 certified plant with full traceability from raw stock to packed product.
Incoming alloy steel is tested for chemical composition, hardenability and grain size before release to production lines.
During manufacturing, tooth profile, lead, index, bore diameter and keyway dimensions are monitored continuously by trained operators.
Post-production checks include hardness testing, tooth contact pattern inspection and dimensional verification to confirm specification compliance.
Sample gears from each batch undergo fatigue testing and wear testing to prove long-term durability and stable performance.
Only gears that pass every quality gate are released, so you receive a dependable, high-performance engine component every time you order.
Cheap aftermarket oil pump gears often use low-grade steel, poor heat treatment or inaccurate tooth profiles that lead to rapid wear.
Those shortcuts create noise, vibration, oil pressure loss and gear tooth breakage in demanding construction and mining conditions.
The genuine 800167156 is built to exacting XCMG standards, delivering correct fit, quiet operation and durable performance on site.
