Original Transmission PartsAuxiliary Countershaft Assembly 12JSD200T-1707051 for Shacman Sinotruk Howo Dongfeng Truck Parts

Product Overview

Product Name: Auxiliary Countershaft Assembly
Part Number: 12JSD200T-1707051
Description:

This component is located inside the auxiliary box (rear auxiliary gearbox/reduction mechanism) of the transmission. FAST 12-speed transmissions utilize a main box + auxiliary box combination. The auxiliary box features a dual-countershaft design to split the torque, and the "1707051" is the short countershaft assembly (which pairs with the 1707047/1707050 long countershaft).

Applications

Major Truck Brands: SHACMAN (Delong F3000, X3000 series), SINOTRUK (HOWO), FOTON AUMAN (GTL, EST series), FAW JIEFANG, and DONGFENG Commercial Vehicles.
Common Vehicle Types: Heavy-duty dump trucks, logistics tractors, concrete mixers, and other high-horsepower, heavy-load commercial vehicles.

Product Features

Twin-Countershaft Load Distribution: It perfectly fits the dual-countershaft power-splitting structure, ensuring uniform load distribution on the auxiliary gears and significantly increasing the torque capacity of the rear box.
High-Strength Welding Process: The gear and the shaft are fused using advanced friction welding or electron-beam welding technologies, preventing snapping or weld failure under heavy loads and high-torque impacts.
Wear and Fatigue Resistance: The gear teeth undergo precise carburizing, quenching, and fine grinding, providing excellent surface hardness, low running noise, and prolonged service life.

Maintenance

When replacing or repairing the auxiliary countershaft assembly, it is highly recommended to inspect or replace the following interconnected components:

12JSD200T-1707047 / 1707050: Auxiliary Countershaft Welded Assembly (Long Shaft with splines, which works in pair with the 1707051).
Auxiliary Box Synchronizer Assembly: The synchronizer ring and sliding sleeve used for high/low gear shifting (e.g., 12JS160T-1707140).
Bearings: Front and rear needle roller bearings / tapered roller bearings for the auxiliary countershaft.
Auxiliary Drive Gear / Auxiliary Main Shaft Gear.
Seals & Gasket Kits: Rear cover oil seals, paper gaskets, and O-rings for the auxiliary box.

Shaanxi Jufeng Delong Co., Ltd specializes in premium truck spare parts with extensive industry expertise. Our components are compatible with major truck brands including SINOTRUCK HOWO, SHAC, FOTON, FAW, BENZ, LIU GONG, and XCMG. We offer comprehensive OEM and ODM services.
