Product catalog summary
Description
The MM W4000 is a vertical offset, remote mount marine transmission designed for continuous duty applications, particularly in workboats. It features a robust design, is fully tested for reliability, and is simple to install. The transmission complies with ISO 9001 standards and includes hydraulically actuated multi-disc clutches for reverse reduction. It is compatible with various engines and propulsion systems and allows for easy onboard maintenance.
Features
The transmission includes case-hardened and precisely ground gear teeth for durability and smooth operation. It has an output shaft thrust bearing to handle maximum propeller thrust in both directions. The hydraulic shifting is smooth and reliable, with a control lever for different operating systems. It is suitable for twin-engine installations and includes an emergency "get home" capability. The casing is made of robust cast iron, and the unit is free-standing with an oil cooler, integrated brackets, and flexible hoses.
Options
Available options include engine-matched torsional coupling, propeller shaft flange and coupling bolt sets, classification by major societies, PTO (live or clutchable), trolling valve for slow-speed drive, adapter flange for SAE 0 and SAE 00 connections, standby oil pump, and electric clutch control (24 VDC).
Ratings
The document provides detailed ratings for continuous duty applications, with various ratios and specifications for different operational conditions.
Dimensions
The transmission's dimensions are provided in both millimeters and inches, along with weight and oil capacity. Specific dimensions for SAE bell housing and output coupling are also detailed.
