INSTALLATION & MAINTENANCE CONE RING COUPLINGS (STANDARD & BRAKE DRUM TYPES)

1.1 INSTALLATION OF THE HUBS (Parallel Bores) a) Ensure all parts are clean and free from grit. b) Check key fit in both shaft and hubs. c) Install each coupling half on its shaft, the half containing the rubber elements on the driven shaft. For press fits apply an appropriate lubricant to the hub bores and shafts, ensure the hubs are square with the shafts and the keyways are in line before pressing on. d) Set gap between coupling halves (table 3). e) Adjust for acceptable shaft alignment as per section 1.3. Note: use metal shim strips under feet as packing to achieve adjustments. a) Remove...

1.2.2 TO REMOVE a) Slacken all screws by several turns. Remove one (size 08 to 10, remove two) and insert it (them) into the jacking off holes shown thus in diagram, after oiling thread and point of grub screws or thread and under head of cap screws. b) Tighten the screw(s) until the bush is loosened in the hub and the assembly is free on the shaft. c) Remove the assembly from the shaft. 1.3 SHAFT ALIGNMENT a) Check shaft alignment as follows:Errors of alignment fall into categories of angularity (see ¿gure 1) and eccentricity (see ¿gure 2), or a combination of both. Errors of angularity should...

2.0 MAINTENANCE 2.1 CONE RING INSPECTION The maintenance required is to inspect the rubber cone ring periodically (every 6 months) for the amount of wear. If the wear on the outside diameter of the cone ring is greater than that recommended in table 5 then the cones should be changed. TABLE 5 CONE AND PIN DETAILS 2.2 ALIGNMENT CHECK With the pins removed an alignment check in accordance with Section 1.3 should be carried out. 2.3 REPLACEMENT OF THE CONES Two options are available:-i) Purchase new cone rings to fit onto the existing pins ii) Purchase of new pin and cone assemblies (part numbers...
