VII. SERVICE AND MAINTENANCE FLUIDS CONTINUED
Torque Hub® Oil OIL LEVEL - Each Torque Hub® should maintain an oil level of half full at all times. Less than that would limit lubrication, and over half full could cause overheating and damage. To check oil level, position Torque Hub® so one of the drain plugs is positioned at 12 O’clock (fig. 7.4). The other plug will be either at 9 O’clock or 3 O’clock. Remove the lower plug: if no oil comes out, oil level is too low. Check Torque Hub® oil level every 100 hours. FIG 7.4
If EP-90 oil is needed, remove the top plug and fill until it just starts to come out the lower hole (fig. 7.5). With the oil at a satisfactory level, re-install plugs. CHANGE - The Torque Hub® oil should be changed after the first 50 hours of operation. Subsequently, it should be changed every 250 hours after that, or once a year whichever comes first. To change the Torque Hub® oil, position one of the plugs at 6 O’clock, and the other at either 3 O’clock or 9 O’clock. Remove the bottom plug to drain the oil. Once all of the oil is drained, re-install the bottom plug and remove the top plug.
FIG 7.5
Refill Torque Hub® with EP-90 oil as described above. GENERAL MAINTENANCE - If your detasseler is going to sit for an extended period of time, occasionally rotate the hubs by driving the detasseler forward or backward a few feet to adequately coat all internal hub parts (fig. 7.6). This will prevent rusting if moisture inadvertently entered the hub during an oil change. Failure to rotate hub and disperse oil may cause rusting and internal damage.
