OEM 860178161 The XCMG Outer Clutch Plate 860178161 is a genuine steel separator plate that alternates with friction discs inside an XCMG excavator clutch pack.
Issued under the official part number 860178161, the plate gives technicians a correctly sized steel disc for the outer tabs, hub and stack height.
The plate is blanked from flat steel and heat treated, so it stays flat and carries clamp load without warping.
Outer diameter, tab form and plate thickness follow the XCMG drawing, so the plate locates in the basket without binding.
Both faces are ground flat and smoothed, so the friction disc wears evenly and heat spreads across the contact area.
Every plate is checked for flatness, thickness, tab fit and surface finish before the batch is packed for shipment.
Used in travel, swing and steering clutch packs, this outer plate is a low-cost part that protects the whole drive train.
The 860178161 plate is blanked to the XCMG drawing, so the outer diameter, tab form and thickness match the clutch basket.
A heat treated, ground steel body keeps the plate flat, so it does not warp or drag when the pack releases between shifts.
Ground faces give the friction disc a true surface to run against, so wear spreads evenly and hot spots are avoided.
Outer tabs are formed to the drawing and deburred, so the plate locates in the basket and slides freely under pressure.
Correct thickness keeps the pack stack within the service limit, so piston travel and clearance stay as designed.
Because the number matches the OEM part, a technician fits it during a rebuild without machining or shimming.
A surface finish protects the plate from rust in storage, so the contact faces stay clean until the rebuild begins.
A sound plate gives smooth take-up, which reduces shock load on the gearbox and extends final drive life.
Production opens with certified steel strip, examined for grade, thickness and surface freedom from laps before blanking.
Blanks are stamped and tabbed in hardened dies, then heat treated to give the plate strength and resistance to warping.
Both faces are ground to the drawing thickness and checked for flatness, so the plate stacks square in the clutch basket.
Inspectors measure outer diameter, thickness, tab form and flatness against a gauge built for this exact part number.
Batch records trace every 860178161 plate to its steel lot and heat treat run, so a quality question is settled quickly.
A clutch pack stacks friction plates and steel plates, and oil pressure squeezes the stack so torque passes through.
The steel outer plate sits between friction discs and gives them a hard, flat face to grip when the piston applies pressure.
A warped or worn plate slips and chatters, which slows travel, heats the oil and wears every other plate in the pack.
The genuine 860178161 stays flat under clamp load, so friction is spread evenly and no single area overheats.
A sound plate protects the gearbox and final drive, which keeps travel and swing performance steady over the machine life.
The 860178161 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 basket tabs, piston and return springs for wear, and measure the pack clearance before fitting new plates.
Soak the new friction 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 basket tabs 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 860178161 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 surface defects such as scores, burrs and cracks, since these damage friction discs and baskets.
Release checks combine visual review, dimensional verification and a trial fit on the XCMG clutch basket fixture.
Sample plates from each lot undergo hardness and flatness tests after heat cycling to confirm they resist warping.
Low-cost copies often skip grinding, so the faces run rough, wear the friction discs and overheat the pack.
A plate outside the drawing thickness alters the stack height, which brings drag, heat and delayed engagement.
The genuine 860178161 follows the XCMG drawing, so diameter, thickness, tab form and hardness 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 860178161 plate stops a slipping clutch from becoming a gearbox or final drive overhaul.
A warped plate heats the oil and spreads debris through the circuit, which shortens the life of pumps and valves.
A correctly ground plate gives smooth take-up, so the friction discs 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 860178161 plate with efficient blanking and grinding runs that hold production scrap down.
A long service life means fewer replacements, which cuts the steel and energy tied to each plate.
Preventing clutch slip reduces oil heating and leakage, helping operators meet rules on sensitive sites.
The steel used here satisfies RoHS and REACH requirements for safe handling and responsible end-of-life recycling.
The 860178161 plate is held in XCMG warehouses supplying North America, Europe, Asia and Australia.
Each plate is bagged to protect the ground 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.
