ZF TRANSMISSION MODEL S5-42 S5-47 S5-47M SERVICE MANUAL
The transmission features an aluminum case (7005) with an integral clutch housing. Because of the aluminum case, the tapered roller bearings of the transmission shafts must be fitted under preload. This is because heat expansion of the aluminum case is greater than that of the steel alloy mainshaft and countershaft cluster gear (7113). If the bearings were not pre-loaded, this would result in excessive end play when the case expands in warm, loaded operating conditions.
The transmission also features shrink-fit gears on the countershaft cluster gear. Shrink-fit gears are connected to the countershaft duster gear by friction only, rather than connected through splines. The gear is heated and lightly pressed onto the countershaft duster gear. The subsequent cookng of the gear provides the shrink fitting. The countershaft duster gear is serviced as an assembly.
NOTE: For vehicles equipped with the 7.3L Diesel Engine, this transmission requires use of synthetic MERCON® (Ford part number E6AZ-19582-B, or equivalent meeting Ford specification ESR-M2C163A2) Multi-Purpose Automatic Transmission Fluid or equivalent.
