OEM WG9925820031 • Center mounting holes • Sealed bearings • Vibration resistant • Direct OEM fit
The WG9925820031 Motor Assembly (Mounting Holes in the Center) is a critical electrical drive component in the chassis and cab systems of SINOTRUK Howo trucks. It converts 24V DC electrical power into controlled rotary motion, driving mechanisms such as cab tilt pumps, HVAC blower units and auxiliary actuators.
This WG9925820031 assembly is precision-manufactured to exact OEM dimensions. The stator and rotor laminations are stacked and bonded for low loss, the commutator is machined for smooth brush contact, and the output shaft runs on pre-lubricated sealed bearings. The center-mounted fixing holes match the factory bracket pattern exactly.
Common signs that a motor assembly needs replacement include slow or stalled operation, excessive current draw, blown fuses, unusual noise or vibration, a burning smell, and visible brush wear or commutator scoring. Fitting a new WG9925820031 unit restores full drive performance and correct electrical behaviour.
Whether you are repairing a faulty cab tilt system, replacing a worn blower motor or carrying out preventive maintenance on a fleet of Howo trucks, the WG9925820031 Motor Assembly delivers the quality, reliability and durability that SINOTRUK Howo professionals expect.
The WG9925820031 Motor Assembly is designed for SINOTRUK Howo trucks, with primary compatibility across the A7, T7H, HOWO 371 and HOWO 380 series. It is a direct OE replacement, so it bolts into the original center-hole bracket and plugs into the factory harness without modification.
This assembly is essential in applications where reliable auxiliary drive power is critical, such as long-haul transport, construction, mining and municipal service. In these duties, the motor must deliver consistent torque without overheating and resist vibration, dust, heat and contamination.
When replacing the motor assembly, it is recommended to inspect the mounting bracket, wiring harness, fuse and relay, and the driven mechanism for wear or damage. The WG9925820031 is designed to work with the factory electrical system, ensuring correct current draw and reliable operation.
For fleets with multiple HOWO trucks, standardising on the WG9925820031 Motor Assembly simplifies electrical repair inventory and ensures the correct motor is available for scheduled maintenance or emergency repairs.
Replacing the WG9925820031 Motor Assembly is a straightforward procedure that requires basic electrical knowledge and hand tools. This work should be performed by a qualified technician. Begin by disconnecting the battery negative terminal and releasing any stored energy in the driven mechanism.
Locate the motor on the chassis or cab. Disconnect the electrical plug from the old motor, noting the locking tab orientation. Remove the mounting bolts from the center holes and withdraw the motor from the bracket. Inspect the bracket and coupling for wear or damage.
Fit the new WG9925820031 motor onto the bracket, aligning the center mounting holes with the factory bolt pattern. Tighten the bolts to the correct torque, then reconnect the electrical plug until it clicks into place. Reconnect the battery and test the motor through its full operating range.
For ongoing maintenance, periodically check that the motor is securely mounted, that the electrical plug is free from moisture or dirt, and that the housing is not overheating. If operation becomes slow or noisy, inspect the brushes and bearings before replacing the motor again.
The WG9925820031 Motor Assembly is manufactured in an ISO 9001-certified facility using precision winding, automated lamination stacking and controlled bearing press-fit processes. Raw materials are sourced from certified suppliers and undergo incoming inspection for conductor grade, insulation class and housing dimensions.
Each motor is assembled on precision lines and then tested for no-load speed, current draw, insulation resistance and high-potential withstand. The output shaft is checked for run-out, and the mounting holes are verified against the OEM gauge. Every unit runs through a loaded break-in cycle before packing.
Random samples from each production batch undergo environmental testing, including thermal cycling, humidity exposure, vibration and dust ingress, to validate long-term reliability in heavy-duty truck applications. These tests ensure the motor continues to perform in the harsh conditions experienced by SINOTRUK Howo vehicles.
We back the WG9925820031 with a comprehensive 12-month warranty against material and workmanship defects. Our rigorous quality control ensures that every motor assembly delivers the same fit, function and durability as the original factory component.
The WG9925820031 Motor Assembly is a vital component for maintaining reliable auxiliary drive power, cab comfort and operational efficiency on your Howo truck. A faulty motor causes stalled mechanisms, blown fuses and unnecessary downtime, especially when the vehicle is needed most.
Manufactured from high-grade steel and copper with sealed bearings and a sealed electrical plug, the WG9925820031 offers outstanding reliability, heat resistance and long-term durability. Its direct-fit design ensures straightforward installation and immediate compatibility with the factory electrical system.
Fleet operators benefit from reduced electrical downtime, lower maintenance costs and improved vehicle availability. Owner-operators gain peace of mind knowing their auxiliary systems are driven by a motor that meets strict OEM standards and is backed by a comprehensive warranty.
