H56C H56C Japanese Craftsmanship Service Manual

INTRODUCTION To insure a long life for the machine and the engine and to prevent failure and problems, proper operation, maintenance and repairs are imperative. This service manual includes an “outline,” “structure and operation,” “inspection and ad- justment,” “disassembly and assembly,” “standard maintenance,” and “repair and replace- ment of parts” of the machine which are necessary to carry out the inspections and repairs in the repair shop. We trust that this manual will help you to effectively carry out the necessary. Repairs should they arise, also provide a accurate description of the product, and the correct repair procedures.

1 PRECAUTIONS ON MAINTENANCE 1. Correct operation Correct operation means to follow the correct “procedure” and “method.” Procedure focuses on speed and accuracy of each job. In the method, are addressed what type of facility, tools, instruments, materials, oil should be used, how and which part should be checked, adjusted or disassembled, and what matters to attend to. 2. Precautions on operation 1. Safety check Check that stoppers and sleepers are correctly installed for the vehicle jack-up operation. 2. Preparation Prepare all of the tools and inspect and adjust the instruments. 3. For efficiency 1) Understand the state before disassembly. What is the problem? Is disassembly absolutely necessary? 2) Before disassembly Determine whether match marks are necessary. For the electrical system, discon- nect the cable from the battery terminal. 3) Precautions for disassembly In stead of checking all of the disassembled parts at once, check each part individually as it is disassembled. When removing the hydraulic unit or the hoses, mount a dust cap on the connection. 4) Repair of disassembled parts Keep the disassembled parts in order. Clearly distinguish the parts to be replaced with new parts from those to be reused. Packings, seals, rings, split pins must be replaced. NOTE: Electrical equipment, rubbers and V belts (which are easily affected by water and oil) must be handled carefully in order to prevent soiling them. 5) Clean disassembled parts Thoroughly clean the disassembled parts. 6) Assembly Perform the assembly correctly (tightening torque, application of Three Bond, screw lock, grease, use of seal tape, etc.). Also install the hose correctly. 1-1 Hose mark Hose mark
