Product Introduction

• Structure: A precision-machined gear made from high-strength alloy steel, with a carburized and hardened tooth surface for maximum wear resistance. It features an integral inner bore with a smooth, polished finish for low-friction rotation on the intermediate shaft.

• Performance: The high-hardness tooth surface withstands the high torque and impact forces of heavy-duty operation, ensuring reliable power transmission and long service life. The precision-machined tooth profile ensures smooth meshing with other gears, minimizing noise and vibration.

Core Function

1. Torque Transmission: Transmits rotational torque from the input shaft gear to the intermediate shaft, facilitating power transfer through the transmission.

2. Gear Ratio Matching: The precise tooth count and profile contribute to the transmission’s overall gear ratio, enabling optimal engine performance and fuel efficiency.

3. Wear Resistance: The carburized and hardened tooth surface resists pitting and wear, maintaining gear integrity even under prolonged heavy load.

Frequently Asked Questions

What is the function of the Front Middle Gear 200-11306-5007 in the Sitrak transmission?

This front middle gear acts as an intermediate transmission element within the gearbox. It meshes with adjacent gears to transfer rotational power from the input shaft toward the output shaft. Without a properly functioning intermediate gear, the transmission cannot deliver smooth and reliable power to the wheels.

How can I verify that this gear fits my specific Sitrak truck model?

The most reliable method is to cross-reference the OEM part number 200-11306-5007 with your vehicle’s parts catalog or maintenance manual. If you are unsure, simply provide your truck model, VIN, or gearbox model number to our team, and we will confirm compatibility before you order.

What material is this front middle gear made from, and how does that affect durability?

It is manufactured from high-grade alloy steel that undergoes carburizing and quenching processes. This treatment creates a hard, wear-resistant tooth surface (HRC 58–62) while maintaining a tough core. The result is a gear that resists pitting, spalling, and fatigue failure — even under sustained heavy loads.

How do I know when the front middle gear needs replacement?

Common warning signs include increased transmission noise (especially a whining or grinding sound), difficulty shifting gears, metallic particles in the gearbox oil, and excessive gear backlash detected during inspection. If your mechanic reports worn or chipped gear teeth during a routine overhaul, replacement is strongly recommended.

Is this an original gear or an aftermarket replacement?

Mettlead supplies OEM-equivalent parts manufactured to the same dimensional and material specifications as the original. They fit and perform identically to factory-installed gears, but at a more competitive price point thanks to our factory-direct supply model.

Can I order this gear alongside other Sitrak gearbox components?

Absolutely. We carry a comprehensive range of Sinotruk Sitrak transmission parts — from shafts and synchronizer rings to bearings and seals. Ordering multiple components together often qualifies for better pricing and consolidated shipping.
