5050610317 – MTU396 Torsion Spring

5050610317 – MTU TORSION SPRING Attributes:

The MTU 12V396TC13 diesel engine is a high-performance model in the MTU 396 series. It adopts a 12-cylinder turbocharged design and is widely used in scenarios such as ship propulsion and emergency power supply.

Installation and Maintenance Key Points:

1. Installation Specifications
– 1. Preload control: Use a special torque wrench and adjust the preload torque according to MTU manual requirements (inferred value: 30-50 N·m).

– 2. Direction mark: One end of the spring is marked with R/L (right-hand rotation/left-hand rotation), which must be consistent with the rotation direction of the matching component.

– 3. Clearance check: After installation, measure the difference between the free length and compressed length of the spring to ensure the deformation is within the design range.

2. Maintenance Cycle
– 1. Regular inspection: After every 250 hours of operation, use an endoscope to check for cracks or wear on the spring surface.

– 2. Lubrication requirement: Use high-temperature lithium-based grease (such as Klüber GPL 232) to lubricate the contact surface between the spring and the support to prevent dry friction.

– 3. Replacement condition: When the free length of the spring is shortened by more than 3% or there are corrosion pits with a depth of >0.1 mm on the surface, the spring must be replaced immediately.
