POWER TAKE OFF 00-13 7. Raise the body (cargo deck) up to the most raised position in the idling state and apply the safety rod and the safety strut to the body (cargo deck). Then prevent drop and check safety. 8. After having the body (cargo deck), stop the engine and remove the test hose installed in Item (3) from the oil pump, then release it from the fluid contain- er. 9. Remove the test hose connecting joint from the low-pressure side of the oil pump and install the joint for connecting the original low-pressure hose. 10.
Release the low-pressure side hose removed from the oil pump and soaked in the fluid container in Item (1) and install it on the low-pressure side of the oil pump as before, then firmly tighten the hose band. [Rear Dump Truck] Hydraulic Operating Fluid Supply 1. Raise the body (cargo deck) in accordance with the “How to raise the body (cargo deck)” described previously. 2. Remove oil filler plug (1) and level plug (2) of the oil tank and supply oil from the oil filler port until the hydraulic operating fluid flows out from level plug (1), then tighten plug (2). 3.
Remove oil filler port plug (5) from the cylinder head, supply the hydraulic operating fluid to “Chamber A” so that no air will be left to fill the chamber with the fluid, and tighten oil filler port plug (5). Notice: For the subsequent work procedure, supply hydraulic operating fluid or perform the air bleeding of hydraulic operating fluid in accordance with each item of the text in the “Supply Procedure of Hydraulic Operating Fluid” or the “Air Bleeding Procedure of Hydraulic Operating Fluid”. Be careful of excessive supply of hydraulic operating flu- id.
If an excessive amount of hydraulic operating fluid ex- ceeding the specified amount is supplied when supply- ing the hydraulic operating fluid at the rise of the body (cargo deck), the hydraulic circuit will be filled with the hydraulic operating fluid because the volume of the fluid in the oil tank is increased more than necessary at the drop of the body (cargo deck). According, the body (cargo deck) will not be dropped from a predetermined place. If it is dropped forcibly, ex- cessive pressure applies to the hydraulic circuit (con- sisting of the hose, pipe, and tank) resulting in its damage or a leak of oil. NPA0026E Legend 1.

Air Bleeding Procedure of Hydraulic Oper- ating Fluid Air Bleeding Method 1. Raise the body (cargo deck) in accordance with the “How to raise the body (cargo deck)” described previously. 2. At the maximum rise, cylinder shaded portions “Chamber A” and “Chamber B” shown in the draw- ing are fully filled with hydraulic operating fluid and Section “C” is filled with the hydraulic operating flu- id up to its level position. Notice:
Be sure to supply a specified amount of hydraulic oper- ating fluid using a cleaned oil supply container paying full attention so that dust or foreign matter will not be mixed in. After having supplied oil, firmly tighten each plug. Notice: Supplying hydraulic operating fluid more than necessary will cause a fault.
