The genuine XCMG 800107075 Solenoid Valve is a high‑performance electro‑hydraulic switching device manufactured for XCMG GR series motor graders. This OEM solenoid valve is used in hydraulic pilot control circuits, transmission shift systems, and brake release mechanisms, providing precise on/off or proportional flow control in response to electrical signals from the machine’s controller. Constructed from high‑grade aluminum or steel housing with a corrosion‑resistant coating, sealed coil, and hardened internal spool, the 800107075 solenoid valve delivers reliable operation under extreme vibration, temperature fluctuations, and continuous duty cycles typical of heavy grading operations.
The 800107075 solenoid valve is a direct‑acting, normally closed or normally open type (depending on application), with a 24 V DC coil and a standard DIN 43650 electrical connector. The valve features a precision‑ground spool and lapped bore, ensuring minimal internal leakage and fast response times. It is rated for working pressures up to 25 MPa (250 bar) and flow up to 30 L/min, making it suitable for pilot‑operated main valves, clutch pack control, and parking brake engagement. This component directly replaces failed or sluggish solenoids on GR135, GR165, GR180, GR215, GR260, GR300, GR350, and GR2003 graders.
A faulty solenoid valve can cause erratic shifting, loss of hydraulic pilot pressure, brake drag, or complete machine immobilisation. Replacing a damaged solenoid with genuine XCMG 800107075 restores original electrical and hydraulic characteristics, ensuring precise control of grader functions. Keep this solenoid valve in your parts inventory for rapid repair of transmission or hydraulic pilot systems.

The 800107075 solenoid valve is a key electro‑hydraulic interface in the grader’s control system. It converts an electrical signal from the operator’s switches or the machine controller into a precise hydraulic pilot pressure, which in turn shifts larger main spools, engages clutches, or releases brakes.
In the transmission, solenoid valves control the flow of oil to clutch packs, enabling smooth gear changes. A sluggish or stuck solenoid can cause incomplete clutch engagement, resulting in slippage, overheating, and eventual transmission failure.
For the parking brake, a normally open or normally closed solenoid (depending on design) releases the spring‑applied brake when the engine is running. If the solenoid fails to actuate, the brake may not release, immobilising the grader, or conversely, fail to apply, creating a rollaway hazard.
The 800107075 solenoid’s fast response time and low internal leakage ensure that pilot circuits respond instantly and maintain pressure without parasitic loss.
XCMG engineers the 800107075 solenoid valve for extreme durability. The solenoid coil is encapsulated in a high‑temperature thermoset resin, protecting the windings from moisture, dust, and vibration. The plunger and return spring are made from stainless steel to resist corrosion.
The valve body is precision die‑cast from ductile iron or high‑strength aluminum, then zinc‑nickel plated to withstand 720 hours of salt spray. The spool is ground to a mirror finish (Ra ≤0.1 μm) and mated to a lapped bore, achieving internal leakage well below industry standards.
Each valve is 100% tested for electrical continuity, coil resistance, response time, and internal leakage. XCMG also performs temperature cycling and vibration tests on random samples to guarantee consistent performance in the harsh under‑hood and near‑transmission environment of a motor grader.
The DIN 43650 connector provides a weatherproof, vibration‑resistant electrical connection, while the O‑ring seals on the mounting face ensure leak‑free hydraulic joints.
Before installing a new solenoid valve, isolate the hydraulic system and relieve pressure. Clean the mounting cavity and the electrical connector. Inspect the O‑ring and sealing surfaces for damage.
Apply a small amount of clean hydraulic oil to the O‑ring. Insert the solenoid valve into the cavity, ensuring it seats squarely. Torque the retaining bolts to the value in the service manual (typically 20–25 Nm for M6 bolts).
Connect the 24 V DC supply, observing polarity if required (check wiring diagram). Use a multimeter to verify coil resistance (typically 20–30 ohms) before energising. Cycle the solenoid several times by applying and removing voltage, listening for a sharp click indicating proper spool movement.
After installation, pressurise the system and check for leaks. Operate the grader through all functions to verify correct control response. Keep spare 800107075 solenoids in your workshop for quick swap‑out during troubleshooting.
Aftermarket solenoid valves often use low‑grade copper windings that overheat and short circuit within months. Many have inferior plating, leading to rust and spool seizure after a few weeks in humid environments.
Counterfeit solenoids may have incorrect electrical specifications (e.g., 12 V instead of 24 V), causing coil burnout or weak actuation. The internal spool clearances are often too large, resulting in high internal leakage and pressure drop.
Genuine XCMG solenoids are manufactured to strict OEM tolerances, with each unit individually tested and serialised for traceability. XCMG provides a 12‑month warranty against manufacturing defects. Using OEM solenoids ensures reliable machine control, preventing downtime and costly transmission or brake failures. The price difference is minimal compared to the cost of a transmission rebuild or a safety incident.
Common symptoms: delayed or harsh gear shifts, failure to engage a specific gear, parking brake not releasing, or hydraulic functions that are slow or intermittent. Electrical symptoms include a burnt odour from the coil, visible melting of the connector, or no audible “click” when energised.
Preventive replacement is recommended every 4,000 operating hours or during any major transmission or hydraulic system overhaul. Solenoids have a finite coil life due to thermal cycling and vibration. Proactive replacement eliminates intermittent faults that are difficult to diagnose.
During each 1,000‑hour service, measure the coil resistance and compare to the specification. If the resistance is out of range by more than 20%, replace the solenoid. Also, check for signs of fluid leakage into the electrical connector, which indicates seal failure.
Keep a stock of 800107075 solenoids in your fleet warehouse. When troubleshooting an electronic control issue, having a known‑good spare solenoid on hand allows rapid swap testing, saving hours of diagnostic labour. Proactive solenoid stocking reduces machine downtime.
