The COGENG Case Solenoid Valve is a high-performance electromechanical component designed for Case IH agricultural tractors, specifically the 155, 165, 170, 185, T1804, T2104, T1554, T1654, and T1754 models. This solenoid valve controls the flow of hydraulic fluid, transmission oil, or fuel (depending on application) by converting electrical signals into mechanical movement.
Solenoid valves are critical for modern tractor functions including:
Transmission shifting (powershift or CVT)
Hydraulic implement control (lift arms, remotes)
PTO engagement
Differential lock activation
Brake valve control
Manufactured under ISO9001 certified processes, this valve features a durable iron body for structural strength and rubber seals to prevent fluid leakage and withstand high pressure (up to 3000 PSI). Each unit is tested for coil resistance, sealing integrity, and response time before leaving the factory.

Q: What Case IH models use this solenoid valve?
A: The COGENG solenoid valve is a direct OEM replacement for Case IH part numbers 84286799, 87723783, 84276869, and 84537085, designed for Case IH tractor models including 155, 165, 170, 185, T1804, T2104, T1554, T1654, and T1754. These multiple part numbers represent supersessions and cross-references of the same solenoid valve. This valve is typically used in the hydraulic or transmission control system. Always verify the specific part number against your machine's parts manual or the original valve's identification label to confirm exact compatibility before ordering.
Q: What are the symptoms of a failing solenoid valve on a Case IH tractor?
A: Common symptoms include the controlled hydraulic or transmission function failing to operate or operating intermittently, slow or delayed response when the function is activated, the solenoid clicking but no hydraulic movement, the solenoid coil overheating, blown fuses related to the solenoid circuit, or the transmission being stuck in a single gear or operating mode. A faulty solenoid valve can also trigger diagnostic trouble codes within the tractor's control system.
Q: What is the relationship between part numbers 84286799, 87723783, 84276869, and 84537085?
A: These four part numbers represent supersessions, updated versions, or cross-references of the same solenoid valve used across different Case IH tractor models and production periods. The COGENG solenoid valve is designed to be a direct replacement for all four part number references, simplifying parts inventory and ordering.
Q: Is this solenoid valve a direct plug-and-play replacement?
A: Yes, the COGENG solenoid valve is manufactured to exact OEM specifications for mounting dimensions, hydraulic port configuration, electrical connector type, voltage rating, coil resistance, and valve spool stroke. It is a direct plug-and-play replacement requiring no modifications when installed on compatible Case IH tractor models.
Q: What voltage does this solenoid valve operate on?
A: This solenoid valve is designed to operate on the standard voltage specified by Case IH for these part numbers. Always verify your machine's system voltage before installation to ensure proper solenoid operation and to prevent coil damage.
Q: What should I check before installing the new solenoid valve?
A: Before installation, verify the hydraulic system is depressurized, inspect the mating hydraulic surface for cleanliness and damage, check the electrical connector for corrosion or contamination, and ensure the O-rings or seals are properly seated. Contaminated hydraulic fluid is a leading cause of solenoid valve failure, so verify fluid cleanliness and replace hydraulic filters if necessary before installation.
Q: What is the warranty coverage for this solenoid valve?
A: COGENG provides a standard 12-month warranty against manufacturing defects from the date of installation. Proof of purchase and installation by a qualified technician are required. Warranty does not cover failure caused by contaminated hydraulic fluid, voltage irregularities, water ingress, improper installation, or use on incompatible equipment.
Q: Does COGENG offer technical support for installation or troubleshooting?
A: Yes, COGENG provides complimentary technical support to assist with installation guidance and basic troubleshooting. For complex hydraulic or transmission diagnostics on Case IH tractors, we recommend consulting a certified Case IH service technician.
Q: How is the solenoid valve protected during shipping?
A: Each COGENG solenoid valve is individually sealed in a moisture-resistant poly bag and packed in a sturdy corrugated carton with protective foam padding. All hydraulic ports and the electrical connector are capped to prevent contamination during transit. Factory direct shipping ensures the product reaches you in optimal condition.
