OEM 860167722 The XCMG Flange Block 860167722 is a genuine machined mounting block that joins a hydraulic component to its housing on XCMG excavators.

Issued under the official part number 860167722, the block gives technicians a correctly machined interface that matches the bolt pattern and the spigot bore.

The body is machined from solid steel or cast iron, so the mounting face, centre bore and bolt holes stay true to the drawing.

Bolt circle, face diameter and block thickness follow the XCMG drawing, so the part seats flat without shims or re-machining.

A protective coating resists corrosion, which keeps the machined faces clean and stops rust bleeding onto the surrounding casting.

Every block is checked for bolt pattern, face flatness, bore size and surface finish before the batch is released to packing.

Used on pump mounts, motor mounts, valve blocks and hose connections, this flange block keeps joints aligned and leak-free.

Key Features and Outstanding Benefits

The 860167722 block is machined to the XCMG drawing, so the bolt circle, centre bore and thickness match the mating housing.

A flat mounting face seats squarely on the casting, so the O-ring or gasket compresses evenly and the joint does not leak.

Bolt holes are drilled and deburred to the drawing, so fasteners slide in and clamp the block without reaming.

Correct centre bore centres the block on the component, which keeps the joint aligned and stops side loading.

The solid body takes full bolt torque without distorting, so the joint stays tight through pressure pulses and vibration.

A protective coating slows rust, so the faces stay clean and the fasteners come out easily at the next service.

Because the number matches the OEM part, a fitter installs it straight from the bag without machining or fitting shims.

A sound block keeps the pump, motor or valve square to its mount, which reduces vibration and extends seal life.

Material Quality and Machining Control

Production starts with certified steel or cast iron, checked for grade, thickness and freedom from porosity or laps.

Blanks are set up on CNC machines and faced, bored and drilled in one fixturing, so the face, bore and holes stay true.

Bolt holes are drilled on a fixed pattern and deburred, so fasteners seat flat and the block pulls down evenly.

Inspectors measure bolt circle, hole size, centre bore, thickness and face flatness on a gauge for this part number.

Batch records trace every 860167722 block to its material lot and machining run, so a quality question is settled quickly.

How a Flange Block Supports Hydraulic Reliability

A flange block provides a flat, rigid face that holds a hydraulic component square to its housing and carries the clamp load.

A warped or wrong-sized block lets the seal seat unevenly, which causes weeping, fretting and a loose mount.

The genuine 860167722 keeps the joint square and tight, so seals work as designed and fasteners stay at torque.

Correct centre bore fit prevents side load on the component shaft, which is a common cause of bearing and seal wear.

A sound block protects pumps, motors and valves, which keeps maintenance intervals predictable and extends life.

Installation Steps and Routine Inspection

The 860167722 block is fitted with a torque wrench, socket set and a new seal kit during hydraulic service work.

Release system pressure, drain the affected line and clean the joint so no dirt enters the circuit during the repair.

Clean the mounting face and check for burrs, scoring or old gasket, since any high spot will tilt the block.

Fit the new seal, locate the block on its centre bore and start all fasteners by hand before tightening any of them.

Tighten the fasteners in a cross pattern to the torque in the service data, so the block pulls down evenly.

Refill with the specified oil, run the machine slowly and check the joint for weeping after the first pressure cycles.

At service intervals, check for oil film, loose fasteners or rust around the block and renew damaged parts early.

Quality Assurance and Validation Testing

Every 860167722 block is produced in an ISO 9001 and ISO 14001 certified plant with traceability from material to carton.

Incoming material is checked for grade, and finished blocks are gauged for bolt circle, holes, bore and thickness.

Each batch is inspected for burrs, cracks and machining marks, since sharp edges damage seals and mating faces.

Post-production checks include visual review, dimensional verification and a trial fit on the XCMG housing fixture.

Sample blocks from each batch undergo coating and pressure checks to confirm sealing and corrosion performance.

Genuine XCMG Versus Aftermarket Alternatives

Cheap copies often have rough or offset bolt holes, so the block cannot be pulled down evenly and the joint leaks.

A block with the wrong centre bore sits off centre, which puts side load on the shaft and wears the seal.

The genuine 860167722 is machined to the XCMG drawing, so bolt circle, bore, thickness and finish match the original.

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 flange block performs reliably in harsh conditions.

Cost Savings and Uptime Advantages

Choosing the genuine 860167722 block prevents a small leak from turning into a damaged pump or motor housing.

A misaligned block wears the seal and shaft, which can stop the machine and contaminate the whole oil circuit.

A coated, correctly machined block comes apart cleanly at the next service, so fasteners and threads survive reuse.

Reliable mounting also extends seal and bearing life, which lowers the total cost of ownership for fleet operators.

Service records from construction and mining fleets show genuine XCMG hydraulic parts cut unplanned downtime.

Sustainability and Lifecycle Considerations

XCMG builds the 860167722 block with efficient machining runs and tight material control that keep scrap low.

A long working life means fewer replacements, which lowers the metal and energy tied to each block.

Stopping joint leaks protects soil and groundwater, helping operators meet rules on environmentally sensitive sites.

The metal in this part complies with RoHS and REACH requirements for safe handling and responsible recycling.

Global Availability and Supply Chain Strength

The 860167722 flange block is stocked in XCMG depots serving North America, Europe, Asia and Australia.

Each block is bagged to protect the machined faces and boxed in a strong carton that guards against damp and impact.

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 faces flat and edges undamaged until fitting, avoiding the burrs seen in loose storage.
