The cover with splash tube, code 300100, is a multifunctional assembly within the MAN L21/31 engine that combines protective enclosure with controlled lubrication management. Designed to protect internal engine components from contamination while simultaneously directing lubricating oil through the integrated splash tube, the assembly ensures effective cooling and lubrication of critical moving parts. Precision-engineered for reliable sealing and accurate fitment, it is manufactured from durable and corrosion-resistant materials capable of operating under demanding thermal and mechanical conditions. By improving lubrication efficiency and reducing uncontrolled oil dispersion, the cover with splash tube contributes to lower component wear, increased operational reliability, and extended engine service life.
