The Engine Mounts system is designed to absorb engine vibrations and torque reactions, preventing them from being transmitted to the chassis and cab. This results in improved driver comfort, reduced noise, and extended service life of driveline components. The robust rubber mounts and high-strength steel brackets ensure that the engine remains securely positioned even under extreme loads.
For complete technical specifications and ordering details, please refer to the official Sinotruk Catalog, which provides comprehensive information on all available variants and compatible truck models for the Engine Mounts.
Whether you are replacing worn mounts or performing a complete engine overhaul, this Engine Mounts kit delivers factory-quality components and a straightforward installation. This Engine Mounts is the definitive choice for operators who demand reliable engine support and long-term durability.
The Spacer Plate is a precision-machined steel component used to adjust the engine mounting height and alignment. In the Engine Mounts system, it ensures proper clearance between the engine bracket and the chassis frame, allowing for correct geometry and load distribution. Made from high-strength steel with a corrosion-resistant coating, it provides a durable and stable mounting interface.
Multiple spacer plates are included in the kit to accommodate different chassis configurations and engine positions, ensuring a perfect fit for the C7H.
The Front Rubber Support Assembly is a key component of the Engine Mounts system, designed to absorb engine vibrations and provide flexible mounting at the front of the engine. It consists of a high-quality natural rubber element bonded to steel plates, offering excellent damping characteristics and resistance to fatigue. This assembly supports the engine’s weight while allowing controlled movement to reduce stress on driveline components.
Its robust construction and precise geometry ensure a long service life and consistent performance under extreme operating conditions.
This high-strength M14 flange bolt features a serrated flange that provides a positive lock against loosening due to vibration. Manufactured from grade 10.9 alloy steel with a zinc-nickel coating, it offers exceptional tensile strength and corrosion resistance. In the Engine Mounts system, these bolts are used to secure the mounting brackets to the chassis and engine block, ensuring a rigid and durable connection.
The fine-pitch thread and serrated flange design prevent self-loosening, maintaining clamping force over the life of the vehicle.
The Stud Bolt is a double-ended fastener used to secure the rubber supports to the engine brackets. It features a precision-rolled thread on both ends, ensuring a tight fit and accurate alignment. Made from heat-treated alloy steel with a corrosion-resistant coating, it provides reliable clamping force and resistance to vibration-induced loosening. In the Engine Mounts system, stud bolts are used for both front and rear supports, ensuring consistent assembly.
Their precise length and thread pitch guarantee proper engagement with the mating nuts, maintaining the correct preload for optimal vibration isolation.
This heavy-duty M18 serrated flange nut is used to secure the rear rubber support assemblies. Manufactured from grade 10 steel with a zinc-nickel coating, it provides high clamping force and resistance to loosening. The serrated flange bites into the mating surface, preventing rotation under vibration. In the Engine Mounts system, these nuts are used in conjunction with the rear support studs to ensure a secure and durable attachment.
The Rear Rubber Support is the primary vibration-damping element for the rear of the engine. It features a large rubber block bonded between steel plates, designed to absorb the high torsional loads and vibrations generated by the engine and transmission. In the Engine Mounts system, this support provides stability and isolation, reducing cab noise and protecting driveline components from shock loads.
Its advanced rubber compound offers excellent resistance to oil, heat, and aging, ensuring consistent performance over millions of kilometers.
The Engine Left Rear Support is a rigid steel bracket that connects the rear rubber support to the chassis on the left side. It is fabricated from high-strength steel with a powder-coated finish, providing a durable and corrosion-resistant mounting point. In the Engine Mounts system, this bracket ensures proper alignment and load distribution, preventing engine movement that could affect driveline angles.
Its precise geometry matches the C7H chassis, allowing for a direct bolt-on installation without modification.
The Engine Right Rear Support is the symmetric counterpart to the left bracket, providing balanced support for the right side of the engine. Identical in construction and finish, it ensures that the rear of the engine is securely mounted and correctly aligned. In the Engine Mounts system, this bracket works with the left support to maintain engine position and prevent excessive movement during acceleration and braking.
This flange nut is used to secure the rear support brackets to the chassis. It features an integrated flange that eliminates the need for a separate washer, simplifying installation and ensuring even load distribution. In the Engine Mounts system, these nuts are made from grade 10 steel with a corrosion-resistant coating, providing reliable fastening under high-vibration conditions.
These general-purpose hexagon flange bolts are used for various mounting points in the Engine Mounts system. Manufactured from grade 8.8 or 10.9 steel with a zinc plating, they provide reliable clamping for light- to medium-duty applications. Their flanged heads eliminate the need for washers, reducing assembly time.
The bolts are available in different lengths to suit different bracket thicknesses, ensuring a proper fit.
This M14 serrated flange nut is used with the matching bolts to secure the front rubber supports and other mounting points. It features the same serrated locking design as the M14 bolt, providing a positive lock against vibration. In the Engine Mounts system, these nuts are made from grade 10 steel with a zinc-nickel coating, ensuring long-term reliability and corrosion resistance.
Their fine-pitch thread and serrated flange design maintain clamping force even under extreme thermal cycling and dynamic loads.
The Engine Mounts system uses high-quality rubber supports that effectively absorb engine vibrations, reducing noise and improving driver comfort. This protects the cab and chassis from fatigue, extending the service life of the vehicle.
This Engine Mounts kit includes every bracket, rubber support, spacer, and fastener needed for a full front and rear installation. No additional parts are required, saving time and ensuring compatibility.
All Engine Mounts components are manufactured from high-strength steel and durable rubber, with corrosion-resistant coatings on all metal parts. This ensures reliable performance under the most extreme loads and harsh environmental conditions.
The Engine Mounts are manufactured to the exact OEM specifications, guaranteeing a perfect fit on the Sitrak C7H. The precision-machined brackets and correctly sized fasteners ensure a hassle-free installation, reducing downtime and labor costs.
