Hyundai R210W-9 Specs Service Manual
Hyundai R210W-9 Specifications Service Manual
This service manual has been prepared as an aid to improve the quality of repairs by giving the serviceman an accurate understanding of the product and by showing him the correct way to perform repairs and make judgments. Make sure you understand the contents of this manual and
use it to full effect at every opportunity.
This Hyundai service manual mainly contains the necessary technical information for operations performed in a service workshop.
For ease of understanding, the manual is divided into the following sections.
SECTION 1 GENERAL SECTION 1 GENERAL
This is a variable displacement double-piston pump for discharge with equal displacements from one cylinder block. This pump is so compact as to appear a single pump though this is actually a double pump.
Because this pump has one swash plate, the tilting angle is the same for two pumps. Tilting of the pump changes in response to the total pressure of P1 + P2. Namely, the output is controlled to the constant value so that the relationship between the discharge pressure and flow rate Q becomes
constant, (P1 + P2) * Q =Constant.
The third pump and pilot pump can be connected to the same shaft via a coupling.
SECTION 2 STRUCTURE AND FUNCTION SECTION 2 STRUCTURE AND FUNCTION
This section explains the structure and function of each component. It serves not only to give an understanding of the structure but also serves as reference material for troubleshooting.
SECTION 3 HYDRAULIC SYSTEM ECTION 3 HYDRAULIC SYSTEM
This section explains the hydraulic circuit, single and combined operation.
SECTION 4 ELECTRICAL SYSTEM SECTION 4 ELECTRICAL SYSTEM
This section explains the electrical circuit, monitoring system, and each component. It serves not only to give an understanding of the electrical system but also serves as reference material for troubleshooting.
SECTION 5 TROUBLESHOOTING SECTION 5 TROUBLESHOOTING
This section explains the troubleshooting charts correlating problems to causes.
SECTION 6 MAINTENANCE STANDARD SECTION 6 MAINTENANCE STANDARD
This section gives the judgment standards when inspecting disassembled parts.
SECTION 7 DISASSEMBLY AND ASSEMBLY SECTION 7 DISASSEMBLY AND ASSEMBLY
This section explains the order to be followed when removing, installing, disassembling or assembling each component, as well as precautions to be taken for these operations.
SECTION 8 COMPONENT MOUNTING TORQUE SECTION 8 COMPONENT MOUNTING TORQUE This section shows bolt specifications and standard torque values needed when mounting components to the machine.
