The power steering pump in a 1991 Jaguar XJ6 is a vane-type pump. This means that it uses a set of vanes that are mounted on a rotating shaft to create pressure in the power steering fluid. The fluid is then used to assist the driver in turning the steering wheel.
Here is a more detailed explanation of how the power steering pump works:
1. The engine drives the power steering pump through a belt.
2. The pump rotates a shaft, which is connected to a set of vanes.
3. As the shaft rotates, the vanes move in and out of slots in the pump body.
4. This creates a vacuum that draws power steering fluid into the pump.
5. The fluid is then pressurized by the pump and sent to the steering gear.
6. The pressurized fluid helps the driver to turn the steering wheel.
Here are some of the benefits of having a power steering pump:
* Makes it easier to turn the steering wheel, especially at low speeds.
* Reduces the amount of effort required to turn the steering wheel.
* Provides a smoother and more precise steering response.
* Helps to reduce driver fatigue.
Here are some of the common problems that can occur with a power steering pump:
* The pump can leak fluid.
* The pump can make noise.
* The pump can fail, which will make it difficult or impossible to turn the steering wheel.
If you are experiencing any of these problems, it is important to have your power steering pump checked by a qualified mechanic.
