The oil filling eye coded K 32379 is a functional element designed to facilitate easy and clean oil replenishment for the barring engine in the Sulzer ZV40/48 system. Typically located in an accessible position, it acts as both an entry point for lubrication oil and a visual inspection aid to monitor oil levels. Its presence ensures that the barring engine remains properly lubricated, minimizing wear on moving parts and contributing to the reliability and longevity of the entire mechanism.
The knob identified by code K 32378 is a user-interface component used for the manual engagement or release of the arrestor pin in the Sulzer ZV40/48 engine's barring system. This small yet crucial part allows operators to control the locking mechanism of the rotating shaft, ensuring safe operation during manual turning or when the engine is stationary. Engineered for ergonomic handling and durability, the knob simplifies an essential safety function in the daily handling of the engine.
The electric motor marked with code number K 32375 is a vital component of the barring engine system in the Sulzer ZV40/48 diesel engine. It provides the power necessary to slowly rotate the engine shaft during maintenance, inspection, or warm-up phases. By enabling controlled and gradual movement, the electric motor ensures technicians can safely align pistons and valves without engaging the full engine power. Its robust design supports consistent performance under varying operational conditions, making it an indispensable part of the engine’s auxiliary functions.
The main bearing cap, code 11.01254-0168.A, is a key mechanical component in the MAN L21/31 engine, responsible for securing the crankshaft bearings firmly in place. Its robust construction ensures that the rotating crankshaft operates with precise alignment under heavy mechanical loads. Proper design and installation of this part are vital for minimizing vibration, reducing wear on the crankshaft, and maintaining the overall integrity of the engine’s lower structure during continuous operation.
The QS Cylinder Crankcase, code 0743748-6.1, refers to a quality-specified version of the engine’s crankcase—one of the most essential structural parts of the MAN L21/31 engine. It provides a strong, precision-machined foundation for housing the crankshaft and other internal moving parts. Designed to withstand extreme loads and vibration, this crankcase is manufactured to the highest quality standards to ensure long-term structural stability in marine propulsion and power generation applications.
The quality specification document, code 10.09004-5200-1.0, for the MAN L21/31 four-stroke engine is a critical technical reference that outlines the exact standards and tolerances required during manufacturing and servicing. It ensures that each component meets MAN Diesel's rigorous performance, material, and dimensional criteria, contributing to engine safety, durability, and reliability. This document is indispensable for quality assurance teams, service engineers, and suppliers working with original or replacement parts.
The housing identified as K 32301 encloses the barring engine mechanism on the Sulzer ZV40/48 diesel engine. Designed to provide structural support and protection, it houses the gearing and drive elements responsible for slowly rotating the engine during maintenance or startup synchronization. Its design ensures secure alignment, easy access for technicians, and durability under varying loads, making it an indispensable part of the engine’s auxiliary systems.
The pointer coded K 32004 is a small yet essential element used in conjunction with the flywheel K 32001 on the left-hand side of the barring engine. It acts as a fixed visual reference point, enabling precise alignment and rotation control during engine barring or manual turning. This function is critical during maintenance and inspection procedures, as it helps ensure safe and accurate positioning of internal engine components.
The flywheel marked K 32001 is a vital rotating mass directly mounted on the crankshaft of the Sulzer ZV40/48 engine. Designed to store rotational energy, it ensures smooth and stable engine operation by evening out power pulses and reducing torsional vibration. This component also plays a key role in starting procedures and timing control, serving as a reference for engine diagnostics. Its robust construction allows it to endure the massive torque and rotational stress typical in large marine and stationary diesel engines.
The complete "VULKAN" vibration damper K 31510 is designed to minimize torsional vibrations in the Sulzer ZV40/48 engine. Manufactured for performance and durability, it enhances the engine’s lifespan, reduces wear on the crankshaft, and ensures smoother operation even in continuous heavy-duty conditions.
