Service Magazine SEPD0468, 19 April 1999, "Proper Differential Warmup and Break-In Can Extend the Service Life of Differential Bearings". Disregard this article. See the replacement article that follows.Note: Correct oil fill is critical. Prior to any operation after maintenance or repair, an oil level check is required. Perform the oil level check only after sufficient time has been allowed for oil to fill all final drive and differential housing compartments.WarmupAfter startup, operate the machine in fourth gear or lower until the oil is at an operating temperature of 43° C (110° F). Providing a gradual warm-up period allows bearing components to maintain optimum operating settings. Operating the machine at high speeds from a cold start causes high temperature gradients between rotating and stationary bearing components. High temperature gradients may result in the degradation of the durability of bearing components.Break-InNote: Correct oil fill is critical. As the last check in the maintenance or repair procedure, the oil level should be rechecked prior to operation. Perform the oil level check after sufficient time has been allowed for oil to fill all final drive and differential housing compartments.Placing a significant load on bearing parts at lower speeds creates a more favorable condition of contact between the mating surfaces than under high speed conditions.Break-in is simply the process of conditioning the running surfaces of gears and bearings to a more optimal state. The best way to break in gears and bearings is to load the truck to a maximum of 60 to 75 percent of capacity. Operate the machine, and limit the top hauling speed to fourth gear for a warm-up period of approximately 15 to 20 minutes. For ERM machines, limit the top speed by 60 to 75 percent of maximum for 15 to 20 minutes.
