OEM 860178228 The XCMG Washer 860178228 is a genuine flat steel washer supplied for XCMG hydraulic excavators and their bolted joints.
Marked with part number 860178228, this factory washer gives fitters the correct thickness and bore for the fastener it sits under.
The washer is punched or stamped from flat steel, then deburred so both faces sit clean and flat against the clamped part.
Inner diameter, outer diameter and thickness follow the XCMG drawing, so the washer seats without rocking or lifting.
A protective coating resists corrosion, which keeps the joint free of rust bleed and makes later disassembly easier.
Each washer is checked for flatness, bore size and burrs before it is packed for shipment.
Used under bolts on covers, brackets, guards, boom plates and hydraulic mounts, this washer spreads load across the joint.
The 860178228 washer is stamped to the XCMG drawing, so bore, outside diameter and thickness match the joint it serves.
A correct washer spreads bolt load over a wider area, which stops soft covers and thin brackets from dimpling.
Flat faces with no burrs sit square under the bolt head, so clamp force stays even around the joint.
The right bore size keeps the washer centred on the bolt shank instead of riding off to one side.
A protective coating resists rust, which prevents staining on painted panels and keeps threads clean for removal.
Because the part matches the OEM number, a fitter uses it straight from the bag without reaming or trimming.
Correct thickness also sets the grip length of the fastener, so the bolt reaches full engagement in its nut or boss.
A proper washer reduces fretting between steel and aluminium parts, which keeps joints tight over long service.
Production begins with certified flat steel checked for grade, thickness and surface condition before stamping starts.
Blanks are punched or stamped in hardened dies, which gives a clean bore and an even outside diameter.
Deburring removes sharp edges from both faces so the washer cannot cut into paint, seals or the mating plate.
Inspectors check bore size, outside diameter, thickness and flatness against a gauge for this exact part number.
Batch records trace every 860178228 washer to its steel coil and stamping run, so any question is settled from paper.
A washer sits between a bolt head and the part it clamps, spreading load and protecting the surface underneath.
Without one, a bolt head can crush thin sheet, crack a casting or work loose as the joint deforms.
The genuine 860178228 keeps the correct thickness and bore, so clamp load is spread evenly and the joint stays tight.
A sound washer also reduces galvanic contact between dissimilar metals, which slows corrosion at the joint.
Clean, flat washers make panels and covers sit square, which helps gaskets and seals seat properly around them.
The 860178228 washer installs with a torque wrench and the correct socket during cover, bracket or panel service.
Remove the old washer, clean the joint faces and check that no paint, dirt or old sealant is trapped underneath.
Fit one washer under the bolt head, and add a second only where the XCMG drawing calls for it.
Seat the bolt by hand until the washer touches the part, then tighten to the torque in the service data.
Check that the washer stays centred and flat as torque is applied, because a tilted washer reduces clamp load.
At service intervals, look for crushed, cracked or rusted washers and replace them before the joint loosens.
Never reuse a washer that has lost its flatness or has been overtightened, since it no longer spreads load evenly.
Every 860178228 washer is produced in an ISO 9001 and ISO 14001 certified plant with traceability from coil to carton.
Incoming steel is checked for grade and thickness, and finished washers are gauged for bore, diameter and flatness.
Each batch is inspected for burrs, cracks and laps, since sharp edges can damage paint, gaskets and mating faces.
Post-production checks include visual review, dimensional verification and a trial fit on the XCMG bolt fixture.
Sample washers from each batch undergo coating and salt spray checks to confirm corrosion performance in the field.
Cheap copies often use thin, soft steel that dimples under torque, so the joint loses clamp load and starts to loosen.
A washer with the wrong bore can ride off centre, and one with the wrong thickness can leave a bolt short of full engagement.
The genuine 860178228 is stamped to the XCMG drawing, so bore, diameter, thickness and coating match the original part.
Using genuine XCMG parts also preserves warranty coverage, protects resale value and keeps fit with the surrounding hardware.
Backed by XCMG global quality standards and technical support, this washer holds up in hot, wet and dusty conditions.
Choosing the genuine 860178228 washer prevents a small fastener problem from turning into a damaged cover or casting.
A joint that stays tight keeps oil inside and water outside, which protects seals, gaskets and internal parts.
Correct washers also prevent bolts from bottoming out or running short, so fitters get it right the first time.
Reliable joints reduce rework and callbacks, which lowers the total cost of ownership for fleet operators.
Service records from construction and mining fleets show genuine XCMG hardware reduces unplanned downtime.
XCMG produces the 860178228 washer with efficient stamping runs and tight material control that keep scrap low.
A long service life means fewer replacements, which reduces the steel and energy tied to each washer.
Tight joints prevent oil and coolant leaks, which helps operators meet rules on environmentally sensitive sites.
The steel in this part complies with RoHS and REACH requirements for safe handling and responsible recycling.
The 860178228 washer is stocked in XCMG depots serving North America, Europe, Asia and Australia.
Each washer is bagged to protect the coating and boxed in a strong carton that guards against damp and distortion.
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 washers flat and clean until fitting, avoiding the bent edges seen in loose storage.
