The WG9725520139 Engine Mounts are premium, heavy-duty chassis vibration-isolation components engineered for SINOTRUK Howo and Hohan N7 series trucks. They support the engine on the chassis frame and absorb the vibration, torque reaction and road shock generated during loaded haulage and daily commercial operation. As a trusted supplier of genuine Sinotruk howo parts, we offer these OEM-grade engine mounts as a direct replacement for the original factory units. The WG9725520139 mounts restore stable engine support on Howo H76/H77 cab chassis and Hohan N7G models.
Manufactured with a reinforced steel bracket, a bonded rubber isolator and corrosion-resistant hardware, these engine mounts are built to exact OEM specifications. Their mounting hole pattern, stud length and rubber stiffness match the factory chassis and engine brackets, so replacement is a direct bolt-on job that keeps the engine aligned with the gearbox and radiator.
OEM WG9725520139 • Heavy-duty engine mounts • Bonded rubber isolator • Direct OEM fit
These engine mounts are the vibration-isolation units that connect the engine to the chassis frame on SINOTRUK Howo H76 and H77 chassis and on the Hohan N7G platform. They carry the engine weight, control its movement under torque and isolate the cab and chassis from engine vibration.
The WG9725520139 mounts combine a reinforced steel bracket, a bonded rubber isolator and corrosion-resistant hardware. The rubber stiffness and bracket geometry follow the original factory design, so the engine stays correctly aligned with the gearbox, driveshaft and radiator without shimming or modification.
Common signs that engine mounts need replacement include excessive vibration through the cab and steering wheel, a clunk when accelerating or shifting, visible cracks or separation in the rubber, a collapsed mount and abnormal engine movement under load.
Fitting the WG9725520139 mounts restores stable engine support, reduces vibration and protects the gearbox, radiator and exhaust connections from stress caused by a loose or collapsed mount. It is a practical repair that prevents secondary damage elsewhere in the driveline.
These engine mounts are designed for SINOTRUK Howo and Hohan trucks, with primary compatibility across the H76/H77 chassis used on HOWO models and the Hohan N7G platform. The WG9725520139 mounts are direct OE replacements that bolt to the factory engine and chassis brackets without modification.
The mounts are critical in applications where the truck operates under heavy load and continuous vibration, such as tipper and mixer work, construction site haulage, quarry support and long-haul transport. In these duties they must resist heat, oil, dust and road shock while keeping the engine firmly located.
Before fitting new mounts, inspect the engine and chassis brackets for cracks, elongated bolt holes or corrosion, and check the gearbox mount and exhaust connections for stress damage. A collapsed mount can allow the engine to move and strain components elsewhere.
For fleets running multiple HOWO or Hohan trucks, stocking the WG9725520139 engine mounts means a replacement is always available when vibration or a collapsed mount is reported, which shortens workshop time and reduces vehicle downtime.
Replacing engine mounts is a job for a qualified technician. Park the truck on level ground, apply the parking brake, disconnect the battery and support the engine securely with a hoist or jack and suitable lifting equipment before starting work.
Remove the mounting bolts from the engine and chassis brackets, lift the engine slightly to take the weight off the mount and withdraw the old unit. Inspect the bracket faces and threads, and clean away dirt, oil and corrosion before fitting the replacement.
Position the new WG9725520139 mount, align the studs with the bracket holes and install the fasteners finger-tight. Lower the engine carefully, check alignment with the gearbox and radiator, then tighten all bolts to the OEM torque.
Run the engine at idle and under load to confirm vibration has reduced and there are no unusual noises. During routine service, check the rubber for cracks or separation and confirm the mounting bolts remain tight.
These engine mounts are manufactured in an ISO 9001-certified facility using reinforced steel brackets, bonded rubber isolators and corrosion-resistant hardware. Incoming materials are checked for hardness, bond strength and dimensional accuracy before assembly.
Each WG9725520139 mount is inspected for bracket alignment, rubber-to-metal bond integrity, stud thread quality and coating coverage. Every batch is checked against the OEM specification, and samples undergo load and fatigue testing.
Batch samples also undergo vibration, temperature cycle and salt spray testing to confirm long-term reliability in heavy-duty truck use. These checks help ensure the mounts withstand continuous engine vibration and the harsh conditions Howo and Hohan trucks face every day.
The WG9725520139 engine mounts are covered by a 12-month warranty against material and workmanship defects. Strict quality control means every unit matches the fit, function and durability of the original factory part.
A worn or collapsed engine mount is more than a comfort issue. It allows the engine to move under torque, which can crack exhaust pipes, strain the radiator hoses and misalign the gearbox and driveshaft. Ignoring the problem leads to much larger driveline repairs.
The WG9725520139 replacement mounts solve the problem at the source. The reinforced bracket and bonded rubber isolator restore factory engine support, reduce cab vibration and protect surrounding components from stress caused by excessive engine movement.
Fleet operators benefit from reduced driveline faults, lower maintenance costs and improved driver comfort. Owner-operators gain confidence from a part that meets strict OEM standards and is backed by a 12-month warranty.
