 FAST EATON Power TakeOff  (PTOs) for C6J40T-B Transmission Gearboxes

FAST EATON C6J40T-B Transmission

FAST EATON C6J Series 6-Speed Manual Transmission

2. Model & Product Technical Interpretation

2.1 Model Nomenclature

C: Super Lightweight Series Transmission

6: 6 Forward Gears

J: Manual Mechanical Transmission

40: Maximum Input Torque: 400N·m

T: Synchronizer-equipped Design

B: Product Improved Version

2.2 Core Technical Features

Structure: Twin-countershaft design for main and auxiliary gearboxes, power split structure enhances load capacity; full helical gear engagement ensures smooth shifting and low noise

Material & Process: Full aluminum alloy housing, which reduces weight while improving heat dissipation efficiency, lowering vehicle curb weight and fuel consumption

Gear Ratio Design: Overdrive configuration. 1st gear ratio 6.01 (large ratio for strong starting and climbing performance), 6th gear ratio 0.77 (reduces engine speed at high-speed cruising for fuel efficiency)

Application Scenarios: Designed for 4.2m blue-card light trucks, 3.8m medium trucks and other urban distribution/short-haul transport vehicles, compatible with Weichai, Yunnei and other 110-160HP engines

Applicable Models: Shaanxi Auto Delong G1, Xuandewing 9, Xuande X9 and other Shaanxi Auto light truck series

2.3 Key Parameter Explanation

Oil Capacity 3.5L: Standard filling volume for the transmission. Strictly follow this volume when adding the specified gear oil during maintenance

Warranty Policy: Customized version for Shaanxi Auto, enjoying 2-year/120,000 km warranty (whichever comes first)

Gear Ratio Range 0.77-6.01: Covers full-scenario demands from low-speed heavy load to high-speed cruising, balancing power performance and fuel economy

3. Operation & Maintenance Tips

Oil Change Interval: After the first maintenance, it is recommended to replace the transmission gear oil every 60,000-80,000 km, and shorten the interval under severe working conditions

Oil Requirement: Use FAST EATON original specified GL-5 grade 80W-90/85W-90 heavy-duty gear oil

Operation Notice: With synchronizer design, fully depress the clutch when shifting to avoid gear impact and extend synchronizer service life

Maintenance Compatibility: Same-platform design, strong parts interchangeability with C6J40T and other models in the same series, convenient for maintenance and repair

4. Supplementary Description

This transmission is a core 6-speed manual product launched by the FAST EATON joint venture for the light truck market. With high reliability, lightweight design and smooth shifting performance, it has become the core supporting transmission for Shaanxi Auto light trucks, widely used in urban distribution logistics, cold chain transportation, green channel transportation and other scenarios.

Full Gear Ratio Table (for Reference)

Truck PTO  Power take off Accessories Parts 

Mounting Location: Auxiliary countershaft side of the gearbox housing (standard side-mounted PTO port, factory pre-configured with cover plate)

Drive Type: Countershaft-driven (constant mesh with transmission countershaft, power available when engine is running, independent of vehicle gear position)

Interface Standard: Compatible with FAST Eaton's light-duty PTO series, matching the flange and spline specifications of the C6J40T series gearbox

Actuation Type: Pneumatic (air-operated) is the standard configuration for light truck applications, with optional mechanical actuation

Application Matching:

Dump Trucks / Refuse Trucks: High-torque, low-speed PTO (ratio ~1.1-1.2)

Water Trucks / Fire Trucks: Medium-speed PTO (ratio ~0.9-1.0)

Cranes / Lifting Equipment: High-speed PTO (ratio ~0.7-0.8)

Installation Notes

Port Preparation: Remove the factory cover plate on the countershaft side, ensure the countershaft spline is clean and undamaged

Sealing: Use the original gasket and sealant to prevent gear oil leakage

Air System: For pneumatic PTO, connect to the vehicle's air tank with a dedicated control valve, ensure air pressure ≥ 0.6 MPa

Alignment: Strictly align the PTO input gear with the countershaft gear to avoid abnormal noise and wear

4.2 Maintenance Requirements

Lubrication: The PTO shares lubrication with the transmission gear oil (GL-5 80W-90/85W-90), no separate lubrication required

Inspection: Check PTO mounting bolts, air lines, and oil leakage at each maintenance interval

Warranty: Modification with non-original PTO may affect the transmission's 2-year/120,000 km warranty

5. Application Scenarios

This PTO interface is designed for light truck (4.2m/3.8m) special vehicle modifications, including:

Sanitation Vehicles: Garbage trucks, sweeping trucks, water sprinklers

Construction Vehicles: Small dump trucks, concrete mixers, aerial work platforms

Emergency Vehicles: Fire trucks, rescue vehicles

Logistics Vehicles: Refrigerated trucks, lifting tailgate trucks

6. Supplementary Notes

The C6J40T-B is a light-duty transmission, so PTO selection must strictly match the input torque limit (≤400 N·m) to avoid gearbox damage

For foreign trade projects, it is recommended to use FAST Eaton's original PTO to ensure compliance with international quality standards and after-sales support
