Material
65Mn spring steel (manganese steel), formed by stamping; surface undergoes black oxidation treatment.
• High elasticity and high strength, does not deform easily under force;
• Blackened for rust prevention, resistant to mud and water corrosion;
• Integrated stamping, with reserved locking bending claws.
Function
1. Anti-loosening locking: After assembly, bend the locking pawl to press against the plane of the nut, locking the main pinion nut of the steering knuckle and preventing the nut from self-loosening due to vehicle jolting or steering vibration;
2. Fix the main pinion clearance, maintain the positioning accuracy of the steering knuckle, and prevent the increase in steering clearance caused by the loosening of the main pinion nut;
3. Safety protection component: Prevent the main pinion nut from loosening, avoid the failure of the steering knuckle, and is a key safety component of heavy truck chassis.
Product features
1. OE original size, precise hole positions, can be directly replaced with the original vehicle parts, and the bending during installation is convenient;
2. 65Mn spring steel material, strong toughness, not prone to breakage even after repeated bending;
3. Blackening surface treatment, resistant to rust in damp and muddy construction environments, long service life;
4. Thin and precise stamped parts, with strict thickness tolerance, ensuring the assembly clearance of the steering knuckle;
5. Han De front axle universal parts, with a large number of Jamaican Shaqi trucks in use, high maintenance demand.
Resolved fault issues:
• The bending claws of the original lock plate were broken or suffered fatigue failure, and the nuts lost their anti-loosening protection;
• The main pin nut gradually loosened, causing excessive steering clearance, large steering wheel deflection, and swaying during driving;
• The loosening of the nuts led to accelerated wear of the main pin, causing front wheel shaking, and posing a danger during high-speed driving;
• The old lock plate was corroded and thinned, losing its locking ability, and there was a risk of the steering knuckle falling off;
• During maintenance and inspection, the lock plate is a one-time component, and it must be replaced each time it is disassembled and reassembled.
What is part number 81.44215.0016?
81.44215.0016 is the front axle knuckle lock washer, also called front wheel lock tab. It is a safety locking part for the steering knuckle kingpin nut on Shacman heavy trucks.
Which trucks can it fit?
It fits SHACMAN Delong F3000, X3000, M3000 with Hande front axle, including tractor, dump truck and tank truck. It is installed on front steering knuckle.
What material is this lock washer made of?
Made of 65Mn spring steel. Stamped one-piece, black oxide finish for rust resistance. It has good toughness and elasticity.
What is its function?
It locks the kingpin nut. After installation, bend the tabs of the lock washer against the nut to stop the nut from rotating loose under vibration and steering impact. It maintains correct kingpin clearance and protects steering system safety.
