Product Introduction

• Structure: Integral precision-forged high-strength alloy steel (20CrMnTi), featuring a large-diameter spiral bevel tooth profile with internal spline for differential mounting. Tooth surface: carburized, quenched, precision-ground to HRC 58–62; black oxide anti-corrosion finish.

• Performance: High hardness resists extreme torque/impact; spiral bevel teeth ensure quiet, smooth meshing with minimal vibration; integral forging prevents deformation under heavy load; precision grinding maximizes power transfer efficiency.

Core Function

1. Torque Transfer: Receives torque from the drive pinion gear and transmits it to the differential, enabling power delivery to the drive wheels.

2. Speed Reduction: Works with the drive pinion to achieve the final drive ratio (typically 3.7–5.7), providing high torque for heavy hauling and climbing.

3. Heavy-Duty Durability: Withstands extreme torque and vibration in off-road, heavy hauling, and long-haul conditions.

Customer Case Study – Transmission Driven Gear DZ9114320646 in Action

Earlier this year, a fleet maintenance company based in West Africa reached out to Mettlead. They managed over 200 SHACMAN F3000 dump trucks operating in a mining region, and their trucks were experiencing premature gearbox failures. After diagnosing the issue, their technical team identified worn transmission driven gears as the root cause.

They ordered a batch of DZ9114320646 Fast Gear driven gears from Mettlead. Upon receiving the shipment, their mechanics noted that the fitment was identical to the original parts — no shimming, no machining, just a clean drop-in replacement. Within three months of installation, gearbox-related downtime dropped by 40%, and the maintenance manager reported noticeably smoother shifting across the fleet.

Since then, this client has expanded their orders to include additional Fast Gearbox transmission components and now treats Mettlead as their primary gearbox parts supplier. Their feedback was clear: “The quality matches OEM, but the pricing and delivery speed are far better than what we got from local traders.”

Frequently Asked Questions – Transmission Driven Gear DZ9114320646

What exactly is the function of the Transmission Driven Gear DZ9114320646 in a Fast Gearbox?

The driven gear sits on the output shaft of the transmission and receives rotational force from the driving gear. In the Fast Gearbox, the DZ9114320646 specifically handles torque transfer at a designated gear ratio, enabling smooth speed reduction and power delivery to the driveshaft. If this gear wears down, you will notice rough shifting, increased noise, and eventually gearbox failure.

How do I verify that DZ9114320646 fits my specific gearbox model?

Start by confirming your gearbox assembly part number — it is usually stamped on the gearbox casing. The DZ9114320646 is designed for Fast Gearbox models commonly found in SHACMAN, SINOTRUK, and FAW trucks. If you are unsure, send us your VIN number or gearbox nameplate photo, and our team will cross-reference compatibility for you.

What material is used, and how long does this driven gear typically last?

This transmission driven gear is forged from high-strength alloy steel, then carburized and quenched to achieve a surface hardness of HRC 58–62. Under normal operating conditions — proper lubrication, standard loads, no chronic overheating — you can expect service life comparable to the original factory gear, typically 200,000–300,000 km depending on application severity.

Can I order the Transmission Driven Gear DZ9114320646 with my own brand packaging?

Absolutely. Mettlead supports white-label and custom packaging for all our gearbox components. You provide your artwork and branding guidelines, and we package the DZ9114320646 driven gear under your label. This is particularly popular among regional distributors building their own aftermarket brand.

What causes premature wear on this driven gear, and how can I prevent it?

The most common causes include contaminated gearbox oil, insufficient lubrication levels, misaligned shafts, or chronic overloading. To maximize the lifespan of your Transmission Driven Gear DZ9114320646, stick to the recommended oil change intervals, use the correct lubricant grade specified by Fast Gear, and avoid operating the gearbox beyond its rated torque capacity.
