The Flywheel housing and flywheel bolt are critical components that connect the engine to the transmission and transfer torque efficiently in the HOWO 7 6X4 Dump Truck. The housing encloses the flywheel, providing protection and structural support, while the bolts secure the flywheel to the crankshaft with precision clamping force. For a complete list of genuine parts, refer to the Sinotruk Catalog which provides detailed specifications and cross-references.
This Flywheel housing and flywheel bolt set includes the Flywheel housing, Flywheel housing bolt (Reference drawing 161500010101), and Flywheel housing bolt. Each component is engineered to withstand high torsional loads and thermal cycling, ensuring reliable power delivery and long service life in heavy-duty applications.
The Flywheel housing and flywheel bolt assembly is manufactured from high-strength ductile iron and alloy steel, with precision-machined mating surfaces and thread forms. The housing provides a rigid mount for the starter motor and transmission bell housing, while the bolts deliver consistent clamp load to prevent flywheel loosening under extreme engine vibrations.
Proper maintenance of the Flywheel housing and flywheel bolt is essential for drivetrain integrity. Using genuine components and following the recommended torque procedures ensures that the flywheel remains securely attached, reducing the risk of catastrophic failure and extending the service life of the HOWO 7 6X4 Dump Truck.
The Flywheel housing is a rigid cast iron enclosure that surrounds the flywheel, protecting it from debris and providing mounting points for the starter motor and transmission bell housing. It features precision-bored pilot holes and dowel pins for accurate alignment, ensuring that the flywheel rotates concentrically with the crankshaft and transmission input shaft. The housing also incorporates oil drain channels and ventilation slots to prevent oil accumulation and heat buildup.
This specific Flywheel housing bolt, identified by reference drawing 161500010101, is a high-strength fastener designed to secure the flywheel housing to the engine block. It is manufactured from heat-treated alloy steel with a controlled thread form and features a reduced shank for enhanced elasticity. This bolt provides the necessary clamp force to maintain the housing’s position while absorbing dynamic loads from the drivetrain.
The standard Flywheel housing bolt is a general-purpose fastener used in various locations on the housing, including the starter motor mounting and bell housing attachment. It is made from medium-carbon steel with a protective zinc plating and features a hex head for easy installation with standard tools. These bolts are designed to provide consistent clamping force and resist loosening due to vibration, ensuring the housing remains securely attached under all operating conditions.

OEM-grade material and dimensional accuracy. Our Flywheel housing and flywheel bolt are cast and forged to the exact specifications of the original design, with controlled grain structure and heat treatment. This ensures perfect fitment with the engine block and transmission, eliminating alignment issues and premature wear.
Precision thread and surface finish. The bolts feature rolled threads for consistent friction coefficient, and the housing mating surfaces are machined to a fine finish to ensure leak-free sealing and stable clamping. This reduces the risk of bolt fatigue and housing distortion under high torque loads.
Corrosion-resistant coatings. All flywheel housing bolts receive a zinc-nickel plating, and the housing is painted with a high-temperature resistant epoxy coating. This protects against rust and chemical attack, extending the service life even in humid or salty environments typical of mining and coastal operations.
Tested in real-world conditions. Our Flywheel housing and flywheel bolt sets have been validated through thousands of hours of operation in HOWO 7 6X4 trucks under full load, including off-road and highway use. They are trusted by fleet operators for their reliability and ability to minimize drivetrain-related downtime.
