Oil pressure of Harley Davidson engine: install a gauge

As we all know, oil is one of the most important (and absolutely necessary) elements in internal combustion engines. This is the "blood" of the machine, which is blown to every corner by the "heart" pump pump pump pump pump pump to complete four basic functions:

• Lubricant to create a slide between moving parts in contact
• Cooling, absorbing part of the heat generated by the engine
• Clean and drag combustion residues and metal or plastic poisons
• Pressurize hydraulic components, such as reservoir, pressure device, etc., to make them work normally.

Pressurization system
The oil flows through all pipes pushed down by the pump and its job is to maintain a constant pressure during engine operation. This pressure can vary with temperature when the viscosity of the oil changes and increases as the engine rotates (therefore, it is better not to slow down the speed, as we may not have pressure in critical areas).
In order to show the correct operation of the system, we will install one Pressure indicator Arlens manufacturer from nice is doing a softil twin cam operation

The needle of the indicator is immersed in liquid silicon to relieve vibration, and bubbles are necessary to allow temperature changes.

Installing the clock
The installation of this kit is very simple. We will start to install the metal whip on the bottom of the watch. It is recommended to use liquid teff to seal the joint properly.

We will continue to place the watch on your stand and gently press the screw to hold it still.

The next step is to remove the two bolts from the spring cover of the rear cylinder to allow direct mounting of the bracket using the new bolts provided in the magazine clips to tighten the bolts to 23 nm.

If you have already registered, please log in first. oil pressure sensorIt's at the bottom of the right shell, and we're going to start taking it out.

Once we take the sensor out of the engine, we roll it up. Setif If you have already registered, please log in first.

Next, we're going to put the sensor back in the cabin, press 14 nanometers. Through this step, we will connect the clock beat to the new adapter.

The kit provides a fixed gallows. We have to put it on the screw and put the hydraulic thrust cover on the rear cylinder Your pressure is 12 nanometers

System check
Using the newly installed pressure indicator, we can check whether it works properly. For this purpose, we will start the engine, check the oil pressure light of the engine, and then turn off.

We will take a short tour until the normal operating temperature is reached (around 110 oC), after which we will verify that the oil level is correct, adding if necessary. In these conditions the indicator reading should be 5-10 psi with the engine idling and 20-38 psi with the motor at 2000 RPM.

It should be noted that these pressures will be significantly higher with the cold engine and will go down a bit with high operating temperatures.
