4. Remove the retaining clip and master link from the chain (Figure 8.47), and remove the chain
from the drum.
5. Reconnect the chain on itself using the master link and retaining clip, and store the chain in a safe place.
6. Use the lifting device to lift out the drum.
7. Store the drum in a suitable shipping container taking care not to damage the flanges or the brake surface.
8. If the drum is being stored for any period, apply grease to the drum journals and bearings as described in 8.36.1 Grease drum bearings on page 175.
NOTE: Please note the information given in 8.36.1.
8.42.3 Refit drum
1. Check the condition of the drive sprocket on the gearbox. If necessary, replace the drive sprocket.
2. Check the condition of the winch frame. Report any damage. 3. Use a rag to clean any excess grease or dirt from the winch frame.
