Inaccurate steering direction. The solutions for a faulty loader steering pump are: 1. Repair or replace the gears or the steering pump; 2.

Power steering pumps are mainly divided into steering assist pumps and brake assist pumps, with the steering assist pump serving as the power source for vehicle steering, acting as the 'heart' of the steering system.
I've been operating loaders for many years and have encountered numerous instances of steering pump failures. The most obvious symptom is when the steering becomes unusually heavy—what used to require a light touch on the wheel now demands full force, as if the wheels are stuck. At the same time, you'll often hear hissing or whining noises during operation, especially when accelerating while turning, which is quite unpleasant. Hydraulic fluid also frequently leaks, leaving oil stains on the ground or around the pump. If not repaired promptly, the problem worsens. The steering system becomes sluggish, making it hard to steer accurately, leading to mistakes during work and even potential loss of control, which is extremely dangerous. So, as soon as you notice these signs, don’t hesitate—stop the machine immediately to check for internal pump wear or clogged oil lines. Regularly changing the hydraulic fluid and filters can help prevent such issues.
