How to Adjust the Heavy Steering of Shacman Trucks?
2 Answers
The hydraulic power can be adjusted by regulating the pressure of the hydraulic system. There is usually a pressure adjustment device near the oil outlet of the power pump. When driving, avoid holding the steering wheel at full lock for extended periods, especially during turns and reversing. If the steering wheel feels heavy, it is advisable to check and adjust the tire pressure. The oil pressure of the power steering pump can be adjusted according to the vehicle speed, making the steering lighter and more stable at low speeds.
I've driven Shacman trucks for many years and encountered the issue of heavy steering several times. It feels like the steering wheel is fighting against you. That time, my first thought was to check the power steering fluid. When I opened the hood, the fluid level was alarmingly low, probably due to aging pipes leaking. Next, I inspected the steering pump belt and found it a bit loose. Tightening it with a wrench improved things slightly, but it still wasn't ideal. Then I tried adjusting the gear clearance in the steering box, as wear occurs over time. This operation requires some patience—not too tight or too loose. Finally, I suspected low tire pressure. Using a pressure gauge, I confirmed it was indeed low. After inflating to the standard value, the steering became much lighter. If you're doing it yourself, remember to start with these simple troubleshooting methods. If that doesn't work, it's best to visit a professional shop—they can use diagnostic tools to identify deeper issues.
