Abstract

An improved splash-type lubrication system (100) for a change-gear transmission (102). A closely fitting gear shroud (104) is provided with upper openings (106, 108, 110) allowing the countershaft and main shaft gears to mesh and directs splashed lubricant (112) toward needle bearings (44) supporting main shaft gears (38, 40) on the main shaft (16).
