The primary reduction and two sets clutches for ahead and astern are arranged in parallel. Construction Description The gearbox consists of following parts and components: 1. Input Shaft Assembly The shaft consists of master gear, torsion bar, bell housing, transmission gear and transmission seat is shrink fit with transmission gears, commecting with tousion bar through integral key. The bell housing is located at the of gearbox to facilitate the renwal of clutch plate. 2. Transmission Shaft Assembly The Construction of transmission shaft is essentially similar to he shaft. 3. Output Shaft Assembly The output shaft consists of bearings, driven gear, output shaft and output coupling. The driven gear is shrunk on the output shaft which connected with output coupling by spline. 4. Casing Assembly The casing assembly mainly of casing , front and rear cover, oil punp, oil scale and filter. The type of pump is BB-B*5A*1 5. Oil Distributor Assembly The assembly consists of distributor carrier, ilter, working pressure gquge and hydlic control assembly. Filter needs cleaning periodically.
