How to Adjust the Heavy Steering of Shacman Trucks?
4 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.
I've been driving a Shacman truck for less than a year, and the first time I encountered the steering being too heavy was absolutely exhausting—my arms were sore and numb. I asked the experienced drivers at the factory, and they suggested starting with basic checks. I learned to park the truck on level ground, turn off the engine, and check that the power steering fluid level was between the marks on the reservoir. If the fluid was low or dirty, I needed to top it up or replace it to avoid system blockages. Then, I tested the sound of the power steering pump—any unusual grinding noise might indicate a faulty pump requiring repair. I also paid attention to how the steering felt after a cold start; if it became heavier as the temperature rose, it could be a sensor issue. These steps took me an hour or two, but they solved the problem, and now regular checks give me peace of mind. If you lack experience, ask a car-savvy friend for help—don't push through and compromise safety.
I've dealt with quite a few truck repairs, and heavy steering is mostly an issue with the power steering system. First, check if the steering fluid is sufficient—top it up with the same type of fluid if it's low. Then, see if the belt is loose; tightening it might make steering easier. Worn or improperly adjusted steering gears can also make steering heavier—try fine-tuning the angle slightly. Additionally, don't overlook tire pressure—low pressure increases resistance, so inflate to the recommended level. If the problem persists, a professional shop might need to inspect the hydraulic pump or electrical system—avoid disassembling it yourself. Early repairs ensure peace of mind and prevent the risk of steering failure.
