This manual mainly covers the technical information required for operations performed in a service workshop. For convenience of understanding, the manual is divided into the following chapters; These chapters, in turn, are divided into each of the main groups of components. It not only serves to understand the structure, but also serves as reference material for locating and troubleshooting. This section also contains troubleshooting and localization tables related to “problems”, to their “causes”. The manuals are divided as follows: Chassis capacity: Issued for each vehicle model. Engine capacity: available for each engine series. Volume of electricity: Volume of additions: different volumes are designed to avoid duplication of the same information. Therefore, in order to deal with all repairs of any model, it is necessary to have adequate volumes for the chassis, engine, electricity and accessories. Get up-to-date information before starting any repairs. Page number at the bottom of the page. Archive the pages in the correct order. The following examples show how to read the page number. Additional pages: additional pages are indicated by a hyphen and a number after the page number. Special or other technical precautions are required when doing this work and maintaining standards. The precautions necessary for choosing a lifting rope or when posture is important for work, etc. places that require special attention during torsion during assembly. Places for coating with adhesives and lubricants, etc. places where you need to add oil, water or fuel and their capabilities. Places where it is necessary to drain the oil or water, and the amount of drain. Hooks have maximum strength in the center. While the load is lifted with two or more cables, the force applied to each cable increases with hooking angles. Turn 55 mm in inches. Find the number 50 in the vertical column on the left; take it as after the stretch of inches to millimeters 00 - the horizontal line from. Find the number 5 in the row at the top and take it as you would and draw a line perpendicular. Take the intersection point of both lines. This item offers a conversion value from millimeters to inches. Therefore, 55 mm = 165 inches. Turn 550 mm in inches. The number 550 is not displayed in the table, so divide by 10 by moving the decimal point one place to the left to convert the number to 55 mm. Follow the same procedure as above to convert from 55 to 165 inches. The initial value was divided by 10 to multiply 165 inches by 10 to return to the original value. This means that 550 mm is 65 inches. 12 These figures refer to temperatures in Fahrenheit or Celsius. If you want to switch from Fahrenheit to Celsius, consider the central column as a table of Fahrenheit temperature and read the corresponding temperature in degrees Celsius in the left column. Specific power: the total amount of oil, including oil from components and pipelines. Be careful when driving on dry ground. Categories "B" and "C" are broad and have restrictions on use. Therefore, check the limitations before use and carefully consider the conditions of use before recommending the appropriate width of the shoe. If necessary, guide the customer when using it. When choosing the width of the shoe, select the narrowest shoe within the range that will not give problems with flotation and pressure on the ground. This surface is designed so that the oil pressure balance is maintained at an appropriate level. Thus, it performs power control, so that the power consumed by the pump does not exceed the engine power. However, in the heavy load mode, there are cases where the function of determining the current motor speed is set, and if the speed decreases due to an increase in load, the pump discharge volume decreases, which allows the recovery rate. This is the pressure of the pump at the opposite end. For the front pump - the pressure of the pump. Thus, the pump discharge volume moves in the direction of increasing. When the servo piston moves on, the piston moves to the left with the help of a rod, an eccentric and a lever. The springs expand and weaken the spring force. When the piston moves to the left, the piston moves to the right with the cam and lever. For this reason, the springs are compressed and squeeze the piston. As a result, the pressure drops and the piston stops moving to the left. In this case, the power source is taken directly from the battery. The main safety valve 4A. When this happens, the pressure in the pump becomes a pressure equal to the adjustable spring load inside the valve. That is, the cutting control is performed. The piston acts as a stopper for the piston. The subsea valve drains the pump flow into a neutral group. When this happens, the pressure in the pump becomes a pressure that is equal to the adjustable load on the springs in the valve. It is not possible to exit a pump under pressure discharged by a pump so that the pressure rises. Features piston, impeller and gear pumps.
