INSTALLATION 1. Clean shaft, bore and outside of bushing, and hub bore of all oil, lacquer, and dirt. File away any burrs. Insert bush on hub so that holes line up. 2. Sparingly oil thread and point of grub screws, or thread under head of cap screws. Place screws loosely in holes threaded in hub, indicated by ○ on above diagram. 3. If a key is to be fitted, place it in the shaft keyway before fitting the bush. It is essential that it is a parallel key and side fitting only has TOP CLEARANCE. 4. Clean shaft and fit hub to shaft as one unit and locate in position desired, remembering that bush will nip the shaft first and then hub will be slightly drawn to the bush. 5. Using a hexagon wrench, tighten screws gradually and alternately to torque shown in table. 6. Hammer against large end of bush using block or sleeve to prevent damage. (Do not Hit Bushing Directly With Hammer). (This will ensure that the bush is seated squarely in the bore.) Screws will now turn a little more. Repeat this alternate hammering and screw tightening once or twice to achieve maximum grip on the shaft. 7. Recheck screw torque after initial run-in, and periodically thereafter. Repeat steps 5 and 6 if loose. 8. Fill all unoccupied holes with grease. Where bushing is used with lubricated products such as chain, gear or grid couplings, be sure to seal all pathways (where lubricant could leak) with RTV or similar material. * If two bushings are used on the same component and shaft, then fully tighten one bushing before working on the other. 其后面还有一个力矩表,哪个螺栓拧到多大力矩,哈哈, |
