The Kobelco 17SR Tier 4 Preface Instructions

Read and understand all Warning plates and decal on the machine before Operating, Maintaining or Repairing this machine. The Kobelco 17SR Tier 4 Excavator Manual has been written for the repair specialist. The serviceman or mechanic may be unfamiliar with many of the systems on this machine. This makes it important to use this manual and be caution when performing service work.

Please go carefully through the Shop Manual of the Excavator before starting any repair work. Use proper lifting procedures when removing any components. Be careful when removing filler caps, breathers and plugs on the machine. Hold a rag over the cap or plug to prevent being sprayed or splashed by liquids under pressure. The danger is even greater if the machine has just been stopped because fluids can be hot.

Use the Shop/Service Manual of the 17SR Tier 4  Excavator as a reference book and source of information even if you are familiar with Excavator technology. Using the Workshop Manual, the experience construction machine mechanic can carry out any necessary repairs expertly.

Sections of the Manual

How to Index each Service manual section. The General of his Service Manual consists of 8 heading as shown above. Each section can easily referred to by indexes appended to the margin of the page as indicated on the right.

HYDRALIC VALVE

(1) Shockless relief valve
The shockless relief valve consists of the direct relief valve (Poppet) and the piston for changing the spring force with two stages.
When the hydraulic motor is stopped, even after closing IN and OUT port of the hydraulic motor, the motor tries to run with inertia. Motor works as like a pump, and the pressure (brake pressure) is made on the OUT port side.
The shockless relief valve releases this brake pressure with two stages of operation. This makes the shock smooth, and prevents the motor being damaged.
It also makes the start of the motor smooth.
