Introduction

• Part Name: High Range Cone Hub Assembly

• OEM Number: WG2203100006

• Applicable Vehicle: SINOTRUK HOWO, A7, HOHAN, Golden Prince, Steyr heavy trucks with HW19710 / HW19712 gearbox

• Function: Installed on transmission auxiliary box, responsible for high-speed gear synchronization. The conical friction surface cooperates with sync ring to balance rotation speed during high/low shift, eliminate gear grinding and hard impact, protect gearbox internal components during long-distance highway transportation.

Production Standard

• Raw material: 20CrMnTi alloy carburized steel, high hardness & anti-wear

• Integral forging + precision CNC turning, strict heat treatment to strengthen cone friction surface

• Standard spline & outer engagement tooth, zero tolerance error, seamless assembly

• 100% full inspection before shipment: hardness test, dimension measurement, surface flaw detection

Key Features

✅️100% OEM Standard Size, Direct ReplacementOE code WG2203100006 fully matches original SINOTRUK gearbox parts, no modification needed during installation, fits perfectly for HOWO HW series sub-transmission.

✅️High Strength Carburized Steel, Ultra Long Service LifeAdopts 20CrMnTi alloy steel with deep carburizing heat treatment. Hardened conical friction surface resists frequent high-speed friction, avoids rapid abrasion, greatly extends service cycle under long-haul heavy load.

✅️Smooth High-Speed Shifting, Stop Gear Grinding NoisePrecision machined taper and spline teeth ensure stable friction synchronization when switching high range. Effectively solve gear clashing, difficult shifting and abnormal noise caused by worn old cone hub.

✅️High Torque Resistance, Adapt to Heavy-Duty Working ConditionsIntegrated forging structure bears large torque output of full-load trucks, stable performance under highway continuous high-speed driving, reduces gearbox overhaul frequency for fleets.

✅️Strict Quality Inspection, Stable Consistent QualityEvery finished cone hub undergoes hardness, dimensional and surface defect tests. No burr, no uneven taper, uniform wear resistance for bulk export orders.

✅️Cost-Effective Aftermarket Spare Parts, Factory Direct SupplyLower price than genuine OEM parts with equivalent performance, stable stock support, fast delivery for global truck spare parts distributors & repair shops.

✅️Wide Compatibility for SINOTRUK Heavy Truck ModelsCompatible with HOWO 336, 371, 420 horsepower dump trucks, cargo trucks and tractors equipped with HW10/12-speed transmission.
