Address Operator Behaviors
Certain operator behaviors can lead to axle overheating. These operator behaviors include:
Resting foot on the left brake pedal during operation. Resting foot on the left brake pedal during operation can result in brake drag and lead to axle overheating. The M-Series tractors have reduced brake pedal dead band compared to previous models. Brake pressure can start to be applied at as low as 20% brake pedal travel. This low brake pedal travel improves brake pedal response, but can make unintended brake drag more likely to occur.
Using right brake pedal to brake from high speed. The left pedal includes a sensor connected to the Transmission Control Module. This left pedal sensor allows the Integrated Braking System to function. This braking system uses driveline retarding to help slow the machine, decreasing the energy that must be dissipated by the brakes. The right brake pedal actuates the brakes only, which increases the energy driven into the brakes, therefore increasing the heat input to the axles.
Disabling Neutralizer in tight truck loading cycles. The Neutralizer feature places the tractor in Neutral based on left brake pedal position, ground speed, and gear. This Neutralizer feature reduces the likelihood that heat will be driven into the axles by driving through the brakes. The Neutralizer has four different settings available: "Normal Slope", "Moderate Slope", "Aggressive Slope", and "Off". Leaving the Neutralizer in "Normal Slope" mode is recommended. The "Moderate" and "Aggressive" modes are intended to prevent the machine from rolling if the application requires braking on a slope. However, if "Normal Slope" mode is neutralizing too soon for a certain application, the operator should try one of the other modes rather than turning off the Neutralizer.
Excessive ground speed. High ground speeds are a significant contributor to axle and brake heat generation. For example, reducing peak ground speeds from 35 km/h (21mph) to 30 km/h (19 mph) can decrease axle heat by 20 percent or more at typical operating temperatures. To maximize efficiency and reduce axle heat, avoid running at ground speeds significantly above what is needed to get into top gear on level ground typically 25 km/h to 30 km/h (15 mph to 20 mph). Later versions of software have a variable speed limiter that can be manually set to the maximum speed needed for your machine. Refer to Service Magazine, SEPD2041, New Software Is Available On M Series Medium Wheel Loaders. This can be an effective way to improve fuel efficiency and axle heat generation.On-Machine Investigation / Machine Conditions That May Be Contributing To Increased Axle Oil Temperatures
Residual Brake Pressure. Verify that there is no residual pressure in the front or rear brakes. There should typically be only 0 kPa to 70 kPa (0 psi to 10 psi) of pressure in the brake system after the brake pedal is released. Residual pressure exceeding 100 kPa (15 psi) can cause the brake piston to actuate and drag leading to elevated axle temperatures and excessive brake wear. If there is residual pressure, check the drain
