Power-Lock ® www.tsubaki.ca AD Installation Guide Installation 1. Verify that all contact surfaces, including the screw threads and screw head bearing surfaces, are clean and lightly oiled. Note: Do NOT use Molybdenum Disulfide, “Molykote” or any other similar lubricants. 2. Slide the Power-Lock ® onto the shaft and into the hub bore, aligning them as required. 3. Tighten the locking screws gradually in the sequence illustrated in Figure 1 below. The tightening sequence is as follows: a) Hand-tighten 3 or 4 equally spaced locking screws until they make contact. Align and adjust the connection. b) Hand-tighten and take up all remaining locking screws. c) Use a torque wrench to tighten the screws further to approximately one-quarter the specified torque (MA – as found in the AD Power-Lock ® specification tables). d) Increase the tightening torque to 1/2 of MA. e) Finally, use the torque wrench to tighten the screws to the full tightening torque (MA). f) Verify that the screws are completely tight by applying the specified tightening torque (MA). Notes: i) Even tightening is best accomplished by turning each screw in increments of approximately 90˚. Fig. 1 Tightening Sequence for Locking Screws (This is only an example - other number of locking screws is possible.) Removal AD Power-Locks ® are not self-locking. The individual rings are tapered so that the inner and outer rings will spring apart after the last screw has been loosened. 1. Loosen the locking screws in several steps following a diametrically opposite sequence. Do not remove the screws completely. 2. Remove the hub and Power-Lock ® from the shaft. Note: If the AD Power-Lock ® is still locked even after loosening the bolts, then insert bolts into the jack screw holes (see photo beside) and screw them in until it unlocks.
