Description

Technical Parameters

The WG9114520041 balance shaft bolt is designed for HOWO heavy-duty trucks-a critical fastener that secures the balance shaft assembly to stabilize chassis performance, reduce engine vibration, and protect driving safety. It fits at the balance shaft-frame connection points, enduring intense torsional forces and road shocks from heavy hauling. Cheap bolts loosen, strip, or snap under stress, leading to balance shaft shift, chassis noise, uneven tire wear, and even accidents-especially bad for trucks on bumpy construction or mountain roads.

This is a must-have replacement for fleets and owner-operators, keeping the balance shaft system solid in tough conditions. It's made to match HOWO OEM specs-no rethreading or modifications needed for direct installation. Whether hauling heavy loads over rough terrain or long hauls, this bolt holds steady clamping force, cutting unplanned downtime.

Key Specifications

Material Grade: 10.9-grade high-strength alloy steel-1000MPa tensile strength, 900MPa yield strength for heavy loads
Size: M20×1.5×120mm (optimized for max clamping force, no frame interference)
Weight: 0.45kg/unit
Torque Requirement: 380–420 N·m (secure fit without over-tightening damage)
Corrosion Resistance: Zinc-plated yellow chromate-720-hour salt spray pass, rust-proof in humid areas
Thread Accuracy: Class 6g precision-no galling/seizing during install/remove
Head Design: Hexagonal with washer face-even load distribution, no bolt tilting

Materials & Production
All components meet HOWO OEM standards, from trusted steel suppliers. Full heat treatment (quenching + tempering) ensures uniform hardness and toughness, preventing brittle breaks. Thread rolling creates stronger, smoother threads; zinc-chromate plating adds anti-corrosion protection. Every bolt is inspected for dimensions and thread quality to fit HOWO parts perfectly.

Quality & Testing

Standard: OEM
Tests Done: Tensile strength, torque clamping, corrosion resistance, dimensional accuracy, on-vehicle vibration tests
Certifications: IATF16949, ISO9001
Traceability: Unique batch code-trackable from raw steel to delivery

Service Life & Performance

Life Expectancy: 300,000km/3 years (normal use); 200,000km (harsh off-road)
50% more durable than 8.8-grade bolts, resisting fatigue under constant chassis vibration. Precision threads maintain clamping force long-term-no frequent re-tightening. Anti-corrosion coating prevents rust and seizing, avoiding costly disassembly issues.

Failure Prevention & Maintenance Savings

Cheap bolts loosen/break, causing balance shaft misalignment, tire wear, and expensive repairs. This WG9114520041 HOWO Balance Shaft Bolt's high-strength build and precision design fix these problems. Longer service life means fewer replacements, while anti-corrosion features cut rust-related maintenance costs for fleets and operators.

Packaging & Labeling

Options: Neutral polybags, custom blister packs, bulk cartons (100 units/carton)
Protection: Anti-rust oil + waterproof wrap (corrosion prevention); foam inserts (thread damage protection in transit)
Markings: OE number, batch code, production date, torque spec, material grade on all units/packages
