OEM 860178245 The XCMG Housing 860178245 is a genuine OEM housing that forms the outer structure of the swing or travel reduction gearbox and supports the internal shafts, gears and bearings on XCMG hydraulic excavators.
Stamped with part number 860178245, this factory housing gives technicians a rigid, accurately machined enclosure that keeps the gear train in correct alignment under load.
It is cast or machined from high-strength iron or steel, with bearing bores, mounting flanges and bolt holes finished to the drawing tolerance.
Exact bore diameters, flange dimensions and mounting hole spacing match the XCMG specification, so the housing bolts to the frame and the internals seat without shimming.
A rigid housing keeps the shafts square and the gear mesh even, which prevents misalignment, reduces vibration and extends bearing and seal life.
Every housing is measured for bore size, flatness and hole spacing before packing, so the part received matches the factory specification exactly.
The 860178245 housing is machined to the XCMG drawing, so the bearing bores and mounting faces line up with the original gear train axis.
A rigid cast body holds the bearings and shafts square, which prevents misalignment that would otherwise wear gears and seals.
Correct bore diameters and tolerances let bearings seat with the specified fit, so they neither spin in the housing nor crush on the shaft.
Exact mounting hole spacing lets the housing bolt to the frame without reaming or slotting, which saves service time.
A bonded anti-corrosion coating protects the housing from mud, water and salt spray, so machined faces stay clean.
A flat mounting face ensures full contact with the frame, which distributes clamping load and prevents distortion.
Since the housing matches the OEM part, a technician rebuilds the gearbox in the expected time without modification work.
Production starts with certified iron or steel checked for grade, hardness and internal soundness before casting.
Bores and mounting faces are machined on CNC centers that hold diameter and flatness within the drawing tolerance.
Hole positions are drilled in a fixture, so the mounting pattern matches the frame on every unit in the batch.
Inspectors verify bore size, flange diameter, hole spacing and flatness against a checking fixture for this part number.
Batch records trace every 860178245 housing to its material lot and machining program, so quality questions are settled quickly.
The housing encloses the gear train and bearings, keeping them clean and aligned so the gearbox can transmit torque reliably.
A worn or cracked housing lets the bearings tilt, which causes vibration, noise and rapid wear on the gears and seals.
The genuine 860178245 keeps the bearings square to the shafts, so load distributes evenly across the gear teeth.
Correct fit prevents outer ring creep, which would otherwise polish the housing bore and cause a loose, noisy assembly.
A sound housing keeps swing and travel smooth, which protects the gear train and reduces unplanned downtime.
The 860178245 housing installs with a socket set, lifting gear and torque wrench during gearbox service.
Drain the gearbox oil, remove the cover and clean the frame area before taking out the old housing.
Inspect the frame, bearings and gears for wear, and replace any part that shows pitting, scoring or discoloration.
Lift the new housing into place, start the mounting bolts by hand, then torque them in a diagonal sequence.
Fit the bearings and shafts, check end play and confirm the gears mesh without binding.
Refill with the specified gear oil, run the machine slowly, and listen for unusual noise during the first cycles.
At service intervals, check bolt torque and look for oil weeping or a loose bearing seat around the housing.
Every 860178245 housing is produced in an ISO 9001 and ISO 14001 certified plant with traceability from material to packed crate.
Incoming material is tested for grade and hardness, and finished housings are measured for bore, flange and hole spacing.
During production, machining parameters and coating thickness are monitored so each unit keeps the designed geometry.
Post-production checks include visual inspection, dimensional verification and a trial fit on the XCMG frame fixture.
Sample housings from each batch undergo load, salt spray and vibration tests to confirm long-term performance.
Cheap copies often use soft material and loose bore tolerance, so the bearings seat poorly and the housing wears oval.
A housing with the wrong hole spacing forces bolts into misalignment, which damages threads and tilts the bearing.
The genuine 860178245 is machined to the XCMG drawing, so bore size, flange and hole pattern match the original part.
Using genuine XCMG parts also preserves warranty coverage, protects resale value and keeps compatibility with other OEM components.
Backed by XCMG global quality standards and technical support, this housing performs reliably in harsh conditions.
Choosing the genuine 860178245 housing prevents a small bearing misalignment from turning into a full gearbox rebuild.
A loose bearing seat allows the outer ring to spin, which polishes the housing and makes a proper repair impossible without welding.
Proper material and accurate machining keep the housing working across a long life, which reduces replacement frequency.
Reliable housing support also extends bearing, gear and oil life, lowering the total cost of ownership for fleet operators.
Service records from construction and mining fleets show genuine XCMG drive parts cut unplanned downtime.
XCMG builds the 860178245 housing with efficient casting and machining processes that keep material scrap and energy use low.
A long working life means fewer replacements, which lowers the raw material and energy tied to each housing.
Preventing oil leaks around the gearbox protects soil and groundwater, helping operators meet site regulations.
The iron, steel and coating in this part comply with RoHS and REACH requirements for safe handling and responsible recycling.
The 860178245 housing is stocked in XCMG depots serving North America, Europe, Asia and Australia.
Each housing is wrapped and packed in a reinforced crate that guards against impact, dust and damp during transport.
Fleet buyers can request volume pricing and combined freight, which simplifies planning and lowers landed cost.
Live stock data and responsive supply teams help cover urgent requests fast, so machines return to work sooner.
Careful packing keeps the housing in factory condition until fitting, avoiding the bore damage and rust seen in loose stock.
The XCMG Housing 860178245 is a key structural component on XCMG excavators, enclosing and supporting the gear train inside the reduction gearbox.
Its rigid cast body, accurate bearing bores and flat mounting face deliver dependable alignment in hot, wet and dusty conditions.
By keeping bearings square and gears aligned, this housing cuts vibration, lowers repair bills and extends component life.
