The YJ380 converter transfers engine power through hydraulic fluid. The engine drives the pump-side member, causing the working fluid to circulate inside the converter and transmit power toward the turbine side connected to the transmission.

Unlike a lock-up torque converter, the non lock up torque converter does not switch to a rigid mechanical connection between the engine and transmission through a lock-up clutch. The hydraulic coupling remains the main method of power transfer.

This makes the converter different from a lock-up design in both construction and operating principle. For a 160hp non lock up torque converter, the engine and transmission specifications should still be checked before selecting the unit.

The non lockup torque converter can be used when the powertrain requires continuous hydraulic coupling rather than a separate direct-drive lock-up stage.

Exact dimensions, torque capacity, speed ratio and other performance values should be confirmed according to the final configuration.

The biggest difference between a non lock up torque converter and a lock-up type is what happens between the engine and transmission during operation.

A lock-up converter can use a clutch to establish a direct mechanical connection at certain operating conditions. The YJ380 non-lock-up configuration does not have this additional direct-drive stage. Hydraulic fluid remains responsible for transferring power.

This means the converter can continue to provide the hydraulic coupling between the engine and transmission while the machine is working under changing loads.

For a YJ380hp non lock up torque converter project, the selection should focus on the actual engine output, input speed, transmission requirements and installation arrangement.

The YJ380 converter can be considered for:

• Crawler bulldozers
• Earthmoving machinery
• Construction equipment
• Mining machinery
• Heavy-duty crawler equipment
• Hydraulic powertrain systems
• Transmission replacement projects
• Non-lock-up drivetrain applications

The non lock up torque converter is especially relevant where the powertrain is designed to operate without a mechanical lock-up stage.

A non-lock-up design can be considered when the machine's drivetrain is intended to maintain hydraulic coupling throughout operation.

It may be suitable when:
• The transmission system does not require a lock-up clutch
• Continuous hydraulic coupling is preferred
• The machine frequently operates under changing loads
• Engine and transmission speeds need to differ during operation
• The existing powertrain already uses a non-lock-up converter

The correct configuration should always be matched to the engine and transmission rather than selected solely by converter type.

For a non-lock-up converter replacement, customers can provide:
• Machine model
• Engine model
• Engine power
• Engine rated speed
• Transmission model
• Original torque converter model
• Installation dimensions
• Input/output connection information
• Product photos
• Technical drawings
• Required quantity

For a non lock up torque converter with a different mounting arrangement, the original converter information can be used for technical matching.
