Minimum hub diameters are determined by hub material. The hub minimum diameters indicated in this publication represent hub material yield point in N/mm2 (σ0.2). Coefficients of Friction Locking assemblies are supplied in a lightly oiled condition. Assemble with this oil coating in place. Locking Assembly µ = 0.12 Screws: µ = 0.14 NB: Lubricants containing Molybdenum disulphide or other extreme pressure additives must not be used. Used locking assemblies should be cleaned and lightly re-oiled before re-assembly. Screws Locking assemblies are fitted with DIN 912 Grade 12.9 screws. At original assembly, the tightening torques shown in this publication should be used. When re-fitting a used locking assembly, reduced tightening torques should be used. Please contact the supplier for reduced torque figures. Screws are to be tightened up to the nominated tightening torque Ma, in a crosswise pattern several times. Ensure that screws either side of the slots are tightened one after the other.

7 Z2 FITTING AND REMOVAL OF Z-LOCK LOCKING ASSEMBLY Fitting: 1. All contact surfaces, including threads and heads of locking screws, have to be clean and covered with an oil film. Shaft, hub and Locking Assembly are to be assembled in this condition. 2. Tighten locking screws lightly and position hub. 3. Tighten locking screws evenly crosswise up to the nominated torque (tighten in 2-3 stages). 4. Re-check the tightening torque of the locking screws all the way round. When no screw can be tightened further with the torque wrench set to the tightening torque Ma, the fitting process is completed. Note: Used Locking Assemblies, prior to fitting, must be cleaned and lightly oiled, then re-assembled as shown in Figure 1. The cadmium plated screws are to be placed through tapped holes of front thrust ring (see dh). Fig,1 1=Rear thrust ring 2=Front thrust ring 3=Outer ring 4= Inner ring Removal: 1. Loosen all screws crosswise several turns. 2. Now the loosened connection can be dis-assembled. If necessary, the front and rear thrust ring can be dis-assembled as shown in Figures 2 and 3.

10 Z5-Z6 FITTING AND REMOVAL OF Z-LOCK LOCKING ASSEMBLIES Fitting: 1. All contact surfaces, including the threads and heads of locking screws, have to be clean and are covered with an oil film. Shaft, hub and Locking Assembly are to be assembled in this condition. 2. Unscrew all locking screws several turns and screw at least three screws into the threads of Parts 2 and 3, so that they press against the stop and hold Parts 1 and 3 away from Part Place locking assembly in hub bore. Take screws from the jacking screw holes in Part 3 and screw back into the threaded holes of Part Tighten screws evenly to the given torque Ma, crosswise covering the circumference several times. (Tighten the screws on both sides of the slot one after the other). When no screw can be tightened any further with the torque wrench set to the tightening torque Ma, the fitting process is complete. Fig 1 1 = Back thrust ring 2 = Internal bush 3 = Front thrust ring 4 = Locking screws DIN Note: Used locking assemblies, prior to fitting, must be cleaned and lightly oiled, then reassembled as shown in Figure 1. On assembly, ensure that both front and back thrust rings and also internal bush have correct orientation, ie: all threaded holes in back thrust ring are opposite through holes in the web of the internal bush and front thrust ring. Removal: 1. Loosen all screws several turns. 2. Insert screws into all jacking screw holes in the front thrust ring and the web of the internal bush, which are screwed out of the back thrust ring. 3. Tighten the screws in the jacking screw holes evenly (the screws on both sides of the slot one after the other), the assembly is then loosened.

15 Z8 FITTING AND REMOVAL OF Z-LOCK LOCKING ASSEMBLIES Fitting: 1. Fit at least 3 screws, evenly spaced around the circumference, into the threaded jacking holes, until resting against the face of the outer hub. This separates the hub and flange, and also stops tilting during assembly. 2. Tighten locking screws carefully until the locking assembly is located in the correct place without any looseness. Remove the lifting screws and tighten with the remaining screws. 3. Tighten all screws evenly to the given torque Ma, crosswise covering the circumference several times. (Tighten the screws on both sides of the slot one after the other). When no screw can be tightened any further with the torque wrench set to the tightening torque Ma, the fitting process is complete. Removal: 1. Loosen all locking screws several turns and insert one screw into each of the flange s threaded jacking holes. 2. Tighten the screws crosswise to loosen the connection. 3. Tighten the screws both sides of the slot one after the other. Tightening Torques for screws Gr DIN 912 Screw M6 M8 M10 M12 M14 M16 M18 M20 M22 Torque Ma (Nm)

18 ZSD FITTING AND REMOVAL OF Z-LOCK SHRINK DISCS Fitting: 1. Before fitting to shafts, remove any spacers that may have been installed between pressure plates for transport reasons. 2. Loosely tighten the screws such that the inner ring will still rotate. 3. Grease the hub on which the inner ring is to be fitted. 4. Slide the shrink disc on to the hub. 5. Slide the hub on to the solid shaft. Both hub bore and solid shaft surface must be ungreased. 6. Ensure that the pressure plates are parallel by carefully tightening screws at a low torque. 7. Begin tightening the screws to full tension Ma, evenly in a clockwise direction (not crosswise). Repeat the clockwise tensioning procedure several times until all screws are tensioned to the recommended torque Ma. Removal: 1. Loosen screws evenly in a clockwise direction several times, take care to keep the pressure plates parallel. For safety reasons do not completely unscrew the screws as this could allow a pressure plate to jump off. 2. Check for and remove any corrosion on hub and shaft, before hub is removed from solid shaft. 3. Remove shrink disc from hub. Used Shrink Discs: Used shrink discs must be disassembled and cleaned. Undamaged bevel surfaces, screw threads and under screw heads should be re-greased with Molykote G Rapid or a suitable equivalent.
