OEM 801977247 The XCMG Return Oil Filter Element 801977247 is a genuine hydraulic filter cartridge that cleans oil returning to the tank on XCMG excavators.
Issued under the official part number 801977247, the element gives the technician a correctly sized cartridge that matches the housing, seal and bypass it is designed for.
The pleated media and end caps are formed to the XCMG drawing, so the element seats in the housing without twisting or leaving a bypass gap.
A matched media grade traps fine wear particles while allowing return oil to flow, so the circuit stays clean without starving the tank.
A reinforced center tube and bonded end caps hold the pleats under pressure pulses, so the element does not collapse or shed media.
Every unit is checked for pleat count, media area, seal fit and bypass opening before the batch is packed for shipment.
Fitted to the return line and tank circuit, this filter keeps abrasive particles away from pumps, valves and cylinders.
The 801977247 element is produced to the XCMG drawing, so the diameter, height and seal fit the housing on the first attempt.
A matched media grade traps fine wear particles, so abrasive grit does not reach the pump, valves or cylinders.
A reinforced center tube holds the pleats under pressure pulses, so the element does not collapse or shed media into the oil.
Bonded end caps seal the media edges, so oil cannot bypass the filter and carry dirt back into the tank.
Because the part matches the OEM number, a fitter installs it straight from the box without adapters or extra seals.
Correct pleat spacing keeps flow steady, so the return line does not build back pressure or starve the tank.
A sound filter also keeps the oil clean, which protects seals and reduces wear on pumps and valves.
Keeping spare elements on the shelf shortens service time, so a clogged filter does not turn into a full day of lost work.
Each lot begins with certified filter media and steel support tested for basis weight, strength and oil resistance before pleating.
Elements are pleated and bonded in controlled tooling, so the pleat count, media area and height stay uniform from batch to batch.
Trimmed edges and bonded caps keep the media sealed, so the element does not leak dirty oil around the ends.
Inspectors measure diameter, height, pleat count, seal fit and bypass opening against a gauge made for this exact part number.
Batch records trace every 801977247 element to its media lot and production run, so a quality question is settled quickly.
A return filter element cleans oil as it flows back to the tank, so wear particles are removed before they circulate again.
A clogged or bypassed element lets dirt reach the pump and valves, which causes wear, sticking and unexpected failure.
The genuine 801977247 keeps the return oil clean, so the circuit stays protected and components last longer.
Correct fit avoids both an element that bypasses dirty oil and one that restricts flow and raises return pressure.
A sound element protects pumps, valves and cylinders, which keeps service intervals predictable and extends machine life.
The 801977247 element is installed with a cleaning cloth, a filter wrench and an oil pan during hydraulic service work.
Release system pressure, drain the housing and clean the cover so no dirt or metal chips enter during the repair.
Check the housing, cover and seal faces for damage, rust or old gasket, since a rough surface will stop the element sealing.
Fit the new element with the correct seal, seat it fully and check that the bypass and center tube line up with the housing.
Tighten the cover to the torque in the service data, so the filter seals without crushing the element or stripping the thread.
Refill with the specified oil, run the machine slowly and check the housing for weeping after the first pressure cycles.
At service intervals, replace the element as scheduled and look for metal debris, which signals wear inside the circuit.
Every 801977247 element is produced in an ISO 9001 and ISO 14001 certified plant with traceability from media to carton.
Incoming media is tested for strength and oil resistance, and finished elements are gauged for diameter, height and pleat count.
Each batch is screened for media damage, bond defects and seal flaws, since these defects cause bypass or media shedding.
Post-production checks include visual review, dimensional verification and a trial fit in the XCMG housing fixture.
Sample elements from each batch undergo efficiency, collapse and oil immersion tests to confirm filtration and strength performance.
Cheap copies often use thin media and weak bonds, so the element collapses or bypasses dirt soon after installation.
An element with the wrong height or seal can sit loose, bypass dirty oil or restrict return flow and raise pressure.
The genuine 801977247 is made to the XCMG drawing, so diameter, height, media and seal match the original part.
Using genuine XCMG parts also preserves warranty coverage, protects resale value and keeps fit with OEM housings.
Backed by XCMG global quality standards and technical support, this return filter element performs reliably in harsh conditions.
Choosing the genuine 801977247 element prevents a small amount of dirt from turning into a damaged pump or stuck valve.
A failed element lets wear particles circulate, which scores machined surfaces and shortens component life.
A correctly made element traps dirt firmly, so it does not bypass and does not shed media into the circuit.
Reliable elements also keep oil clean, which improves machine performance and lowers ownership cost.
Service records from construction and mining fleets show genuine XCMG parts cut unplanned downtime.
XCMG produces the 801977247 element with efficient pleating and bonding runs that keep production scrap low.
A long service life means fewer replacements, which lowers the material and energy tied to each element.
Clean hydraulic oil prevents leaks and contamination, which protects soil, groundwater and internal parts.
The materials in this part comply with RoHS and REACH requirements for safe handling and responsible recycling.
The 801977247 element is stocked in XCMG depots serving North America, Europe, Asia and Australia.
Each element is bagged to protect the media and seal 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 pleats and end caps undamaged until fitting, avoiding the distortion seen in loose storage.
