Refer to Figure 5-10: on page 5-17. 2. With a good machinist rule, measure the exact distance from the inside face of the auxiliary end cover to the near face of the lubricator sprocket. Note the measurement for proper positioning of the new sprocket. Remove chain. 3. Remove the sprocket set screw and sprocket. Detach all tubing to the lubricator. 4. Remove the four mounting bracket capscrews and remove the lubricator. 5. With the lubricator on the bench, remove the Woodruff Key from the shaft and file the shaft to remove any burrs raised by the cup point of the set screw. Install a new O-ring. 6. Install a new No. 204 Woodruff Key after first checking to make sure the key will fit into the new sprocket. If it is too thick, it can be polished with an emery cloth on a flat surface until it can easily slide into the notch. It may also be a little high and require filing of the top edge. 7. After the new key has been installed and it has been determined that the new sprocket will fit, oil the new O-ring and remount the lubricator to the end cover. 8. Put the new sprocket onto the shaft and set to measured dimension. Tighten the set screw. 9. Check alignment to the crankshaft drive sprocket with crankshaft centered in end play, using a straight edge, to within 1/32 inch (1mm). 10.
