Lengths measured from face of clutch housing to front bottoming surface of companion flange or yoke. 2. Weight - Listed weights are with clutch housing* and include standard controls, which consist of gear shift lever housing and gear shift lever. Weight of standard controls is approximately 10 lbs. (4.5 kg.). All weights are approximate. 3. Oil Capacities are approximate, depending on inclination of engine and transmission. Always fill transmission with proper grade and type of lubricant to level of filler opening.
