MTU 0001401182 Exhaust Bellows Compensator
Product Overview
The MTU 0001401182 Exhaust Bellows Compensator is an exhaust-system component used on selected MTU diesel engines. Multiple parts sources identify 0001401182 as an MTU bellows / compensator, and it appears within MTU Series 2000 engine-parts listings under the exhaust system.
The bellows compensator provides a flexible connection within the exhaust system. Its function is to accommodate movement caused by thermal expansion and contraction, engine vibration, and minor alignment changes between connected exhaust components. This reduces mechanical stress on rigid exhaust piping and adjoining components.
Because it operates directly in the exhaust path, the component is intended for demanding conditions involving high exhaust-gas temperatures, vibration, and repeated heating/cooling cycles.

Applications
The MTU 0001401182 is documented within MTU engine parts inventories, including Series 2000 engine components, where it is grouped with exhaust-system parts such as exhaust housings, manifolds, elbows and other exhaust bellows.
Its main functions in the exhaust system are to accommodate:
- Thermal expansion as exhaust components heat up
- Contraction as the engine and exhaust system cool
- Engine-generated vibration
- Small amounts of movement between connected exhaust components
- Mechanical stress that could otherwise be transferred to rigid pipes, manifolds or connections
Cross-Reference / Related Part Numbers
A related variant is MTU 0001401182/87, which is also documented as a compensator/bellows.
The suffix is significant, so 0001401182 and 0001401182/87 should not automatically be treated as identical parts without checking the MTU engine documentation.
Important Notes
Before ordering or installing MTU 0001401182, confirm the engine model, engine serial number, and existing part number. One supplier of the genuine part specifically requests the machine/engine model and serial number to verify the correct MTU component and notes that the product code may have been superseded.
