Abstract: A gearshift interlock is provided including a first shift block operatively associated with a first synchronized gear. The first shift block is movable between neutral and actuated positions and has a detent. A second shift block is provided operatively associated with a second synchronized gear. The second shift block is movable between neutral and actuated positions and has a detent. A lockout member is provided wherein movement of one of the shift blocks from the neutral position toward the actuated position causes that shift block to urge the lockout member to engage the other shift block detent preventing movement of the other shift block.

Abstract: A separator plate assembly for a multi-disc clutch has first and second spaced apart plates welded to wire elements positioned therebetween. The wire elements are spaced apart and cooperate with the first and second plates to define generally radially inwardly/outwardly extending flow paths for lubricating/cooling oil. A template is provided for use in assembling the wire elements to the plates.

Abstract: A drive speed control system having an input shaft and an output shaft in communication with a planetary gear mechanism. The planetary gear mechanism is in communication with a first rotatable drum member and a second rotatable drum member which is positioned radially inward relative to the first rotatable drum member. A first annular inflatable member is positioned radially outwardly of the first rotatable drum member and a second annular inflatable member is positioned radially between the first and second rotatable drum members. The first and second annular inflatable members are in communication with a control system to cause the inflation of the first annular inflatable member to inhibit rotation of the first rotatable drum member and to cause inflation of the second annular inflatable member, when the first annular inflatable member is uninflated, to cause the first rotatable drum member to rotate in unison with the second rotatable drum.
