Go to top of page Free Travel the distance from the normal height of the pedal down to where the linkage begins to disengage the clutch, as measured at the pedal itself. By moving the splitter to the front of the auxiliary gearbox, it became possible to require the splitter shift collar to bring only the mass of the front transmission's mainshaft to synchronous speed during a compound shift. Lining a type of clutch lining known for its extremly smooth operation. Organic linings typically form a complete ring on either side of the clutch disc that is grooved to remove worn material and aid cooling.
Organic discs tend to slip when hot.
Preload is set to ensure that the bearing will operate without either excessive play and consequent roughess or irregular rotation of the parts it supports, or unnecessary load. Typically, spacers are used in assembling the various parts that surround the bearing in such a way that the bearing cones and balls or rollers will be forced together to get this very slight pressure. Since the preload generates a small amount of friction, it is typically measured by determining the amount of torque required to rotate the assembled parts at a slow and regular speed with an in.-lb. A propshaft that is correctly phased will have the yoke bores or flange ears in the same plane. Phasing incorrectly will cause the shaft to wind up and unwind, with premature wear of the components being a consequence.
