The 080021006022 Crankshaft is a premium, heavy-duty chassis engine component engineered specifically for SINOTRUK Howo trucks, delivering reliable conversion of linear piston motion into rotational power for the diesel drivetrain. As a trusted supplier of genuine Sinotruk howo parts, we offer this OEM-grade crankshaft as a direct replacement for the original factory unit. The 080021006022 crankshaft ensures correct stroke, precise journal alignment and dependable performance on Howo A7, T7H and related heavy-duty models.
Manufactured from high-strength forged alloy steel with precision-ground main and rod journals, a durable nitride-hardened surface and a corrosion-resistant finish, the Crankshaft is built to exact OEM dimensions. Its robust construction maintains correct bearing clearances, resists bending and fatigue, and provides dependable performance even under the constant load, heat and vibration of commercial truck operation.
OEM 080021006022 • Forged alloy steel • Precision ground journals • Nitride hardened • Direct OEM fit
The Crankshaft is the backbone of the diesel engine in SINOTRUK Howo trucks. It converts the up-and-down motion of the pistons into the rotary motion that drives the transmission and wheels. The crankshaft must withstand immense bending and torsional forces while maintaining precise journal alignment and oil clearance.
This 080021006022 crankshaft is precision-forged and machined to exact OEM dimensions. The main and rod journals are ground to a mirror finish for correct bearing fit, the oil passages are drilled for proper lubrication, and the counterweights are balanced for smooth operation. The journals are nitride-hardened for wear resistance.
Common signs that a crankshaft needs replacement include engine knocking, low oil pressure, metal debris in the oil pan, excessive vibration, and visible scoring or cracks on the journals. Fitting a new 080021006022 crankshaft restores proper engine rotation and reliability.
Whether you are rebuilding an engine, repairing a bottom-end failure or carrying out a major fleet overhaul, the 080021006022 Crankshaft delivers the quality, strength and durability that SINOTRUK Howo professionals expect.
The 080021006022 Crankshaft 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 fits the factory cylinder block and accepts the original main and rod bearings, flywheel and pulley without modification.
This crankshaft is essential in applications where engine reliability and performance are critical, such as long-haul transport, construction, mining and municipal service. In these duties, the crankshaft must withstand high combustion pressures, continuous rotation and torsional vibration over hundreds of thousands of kilometres.
When replacing the crankshaft, it is recommended to inspect the main and rod bearings, connecting rods, pistons, flywheel and rear main seal for wear or damage. The 080021006022 is designed to work with the factory engine components, ensuring correct alignment and reliable operation. It is suitable for both standard and heavy-duty engine configurations.
For fleets with multiple HOWO trucks, standardising on the 080021006022 simplifies engine repair inventory and ensures the correct crankshaft is available for scheduled overhauls or emergency repairs.
Replacing the 080021006022 Crankshaft is a major engine repair that requires mechanical expertise, specialised tools and a clean workshop. This work should be performed by qualified technicians with experience in heavy-duty diesel engine rebuilding. Begin by removing the engine from the chassis and mounting it on a stand.
Remove the oil pan, timing cover, flywheel and connecting rods. Withdraw the old crankshaft from the block and inspect the main bearings, rod bearings and block saddles for wear or damage. Clean the block and check the main bore alignment before installing the new crankshaft.
Lubricate the new 080021006022 crankshaft journals with assembly grease and carefully lower it into the block. Install new main bearings and torque the main caps to specification. Check the end play and journal clearances. Reinstall the connecting rods, pistons and flywheel.
Reassemble the engine, refill with oil and coolant, and start the engine. Monitor oil pressure and listen for unusual noises. Recheck the bearing clearances after the first few hours of operation. For ongoing maintenance, change the oil and filter regularly and inspect the crankshaft at every major overhaul. Keeping the crankshaft in good condition ensures engine reliability and long life.
The 080021006022 Crankshaft is manufactured in an ISO 9001-certified facility using advanced forging, machining, heat-treatment, nitriding and balancing processes. Raw alloy steel is sourced from certified suppliers and tested for chemical composition, hardness and hardenability before production.
Each crankshaft is precision-machined to exact OEM dimensions. The main and rod journals are ground to the correct diameter and surface finish, the oil passages are drilled and deburred, and the shaft is dynamically balanced. Every unit is inspected for cracks, hardness and runout.
Random samples from each production batch undergo load testing, fatigue testing and salt-spray testing to validate long-term reliability under real-world conditions. These tests ensure the 080021006022 continues to deliver reliable power conversion throughout its service life.
We back the 080021006022 with a comprehensive 12-month warranty against material and workmanship defects. Our rigorous quality control ensures that every crankshaft delivers the same fit, strength and durability as the original factory component.
The 080021006022 Crankshaft is a vital component for maintaining the power, efficiency and reliability of your Howo truck’s diesel engine. A worn or damaged crankshaft causes engine knocking, low oil pressure and catastrophic failure. Replacing it with this genuine OEM-grade crankshaft restores proper engine rotation and power delivery.
Manufactured from forged alloy steel with precision-ground journals and nitride-hardened surfaces, the 080021006022 offers outstanding strength, wear resistance and long-term durability. Its exact OEM fit ensures straightforward installation and reliable operation.
Fleet operators benefit from reduced engine downtime, lower maintenance costs and improved vehicle reliability. Owner-operators gain peace of mind knowing their engine is rebuilt with a crankshaft that meets strict OEM standards and is backed by a comprehensive warranty.
