OEM 860178183 The XCMG Inner Clutch Plate 860178183 is a genuine friction disc that transmits torque inside the clutch packs of XCMG hydraulic excavators.
Stamped and packed under the official number 860178183, the plate gives the rebuilder a correctly sized friction disc for the hub splines and stack height.
A heat treated steel core carries the friction lining on both faces, so the plate takes drive in either direction of rotation.
Outer diameter, thickness and spline form follow the XCMG drawing, so the plate slides onto the hub without binding or rocking.
Oil grooves cut into the lining feed fluid to the working faces, which carries heat away and flushes worn material out.
Every plate is checked for flatness, thickness, spline fit and lining bond before the batch is released to packing.
Used in travel, swing and steering packs, this inner plate is a low-cost part that protects the gearbox and final drive.
The 860178183 inner plate is formed to the XCMG drawing, so the outer diameter, thickness and spline match the original pack.
A flat heat treated core keeps the plate true, so it does not drag or grab when the pack releases between shifts.
Lining is bonded to both faces, so torque is carried in forward and reverse rotation without slip or chatter.
Pressed oil grooves feed fluid across the friction face, which carries heat away and flushes debris from the pack.
Correct lining thickness holds the stack height, so piston travel and running clearance stay as the drawing intends.
Because the part matches the OEM number, a technician fits it during a rebuild without machining, shimming or sorting.
Spline teeth are cut cleanly and deburred, so the plate slides onto the hub and stacks square with its neighbours.
A sound plate gives smooth take-up, which reduces shock load on the gearbox and extends final drive life.
Each run begins with certified steel strip, examined for grade, thickness and surface freedom from laps before blanking.
Blanks are stamped and splined in hardened tooling, then heat treated so the core resists warping under clamp load.
Lining is bonded to both faces under controlled heat and pressure, and the groove pattern is pressed into the surface.
Inspectors measure thickness, outer diameter, spline fit and flatness on a gauge built for this exact part number.
Trace records link every 860178183 plate to its steel lot and bonding run, so a technical question is settled from documents.
A clutch pack alternates friction plates and steel plates, and oil pressure squeezes the stack so torque passes through.
A warped or worn plate slips and chatters, which slows travel, heats the oil and wears every other plate in the pack.
The genuine 860178183 spreads friction evenly, so torque is carried without hot spots, glazing or localised burning.
Correct thickness and flatness avoid drag between shifts, which is the usual source of heat build-up and early failure.
A sound plate protects the gearbox and final drive, which keeps travel and swing performance steady over the machine life.
The 860178183 plate is fitted with clutch tools, a guide sleeve and a torque wrench during a pack rebuild.
Release system pressure, drain the housing and clean the work area so no dirt enters the pack during the repair.
Inspect the hub splines, piston and return springs, and measure the pack clearance before fitting new plates.
Soak the new plates in the specified oil, then stack friction and steel plates in the order given in the service data.
Confirm every plate slides freely on the splines and that the stack sits square before refitting the end cover.
Refill with the specified oil, run the machine slowly and check that travel and swing engage smoothly after the first cycles.
At service intervals, watch for chatter, delayed engagement or discoloured oil and renew the pack before damage spreads.
Every 860178183 plate is made in an ISO 9001 and ISO 14001 certified plant with records from steel strip to sealed carton.
Incoming steel is checked for grade and thickness, and finished plates are gauged for diameter, thickness and flatness.
Each batch is screened for lining defects such as voids, cracks and lifted edges, since these cause slip and chatter.
Release checks combine visual review, dimensional verification and a trial fit on the XCMG clutch hub fixture.
Sample plates from each lot undergo friction, heat ageing and shear tests to confirm they meet the OEM requirement.
Low-cost copies often use thin lining that wears through quickly, so the steel core scores the hub and the pack fails early.
A plate outside the drawing thickness alters the stack height, which brings drag, heat and delayed engagement.
The genuine 860178183 follows the XCMG drawing, so diameter, thickness, spline and lining agree with the original plate.
Staying with genuine XCMG parts also protects warranty cover, supports resale value and guarantees fit with OEM packs.
Supported by XCMG global quality standards and technical back-up, this plate performs in hot, wet and dusty conditions.
Fitting the genuine 860178183 plate stops a slipping clutch from becoming a gearbox or final drive overhaul.
A worn plate heats the oil and spreads debris through the circuit, which shortens the life of pumps and valves.
A correctly finished plate gives smooth take-up, so neighbouring plates wear evenly and the rebuild lasts longer.
Dependable packs keep travel and swing cycle times steady, which lowers the total cost of ownership across a fleet.
Maintenance histories from construction and mining operations show genuine XCMG driveline parts reduce unplanned stoppages.
XCMG produces the 860178183 plate with efficient blanking and bonding runs that hold production scrap down.
A long service life means fewer replacements, which cuts the steel, lining and energy tied to each plate.
Preventing clutch slip reduces oil heating and leakage, helping operators meet rules on sensitive sites.
The materials in this part satisfy RoHS and REACH requirements for safe handling and responsible recycling.
The 860178183 plate is held in XCMG warehouses supplying North America, Europe, Asia and Australia.
Each plate is bagged to protect the friction faces and boxed in a sturdy carton that keeps moisture out in transit.
Fleet purchasers can ask for volume rates and consolidated freight, which simplifies ordering and reduces landed cost.
Current stock information and responsive supply staff cover urgent demands quickly, so equipment returns to work sooner.
Protective packing keeps plates flat and clean until fitting, avoiding the warping that comes from loose storage.
The XCMG Inner Clutch Plate 860178183 is a vital driveline part on XCMG excavators, carrying torque inside the clutch packs.
Its flat core, grooved lining and accurate spline deliver dependable engagement through heat, moisture and abrasive dust.
