1. Carefully clean all the fittings before assembling the digging machine. During the assembly process, it should be kept strictly clean. Any dirt that exists on the assembly surface and the non-assembly surface may cause rapid wear of parts and may even prevent the machine from functioning normally. Drilled, reamed or boring parts are blown with compressed air.
2. On the friction surface of the part, the lubricant should be applied during assembly so that the machine can be sufficiently lubricated at the beginning of operation. After the blanket oil-retaining ring is cleaned, it must be soaked in the oil to allow the oil to penetrate.
3. The thickness of the gasket must be strictly observed during the repair, because the thickness of the gasket often determines the assembly gap between the parts of the machine, thereby affecting the technical performance of the machine. During installation, both sides of the liner should be coated with a layer of grease (except for engine cylinders). The liners must not be bent, cracked, uneven in thickness, or have defects such as tangs or cylinders.
4. Special tools and equipment should be used during the assembly process.
5. Try not to use spanners when tightening bolts and nuts. Use special wrenches or open-end wrenches for various standards. Use torque wrenches for bolts and nuts of important parts and tighten according to the specified torque.
6. All the locking plates, iron wires, and split pins used to lock the bolts and nuts shall be carefully inspected. All defects such as cracks and wrinkles shall be replaced with new ones. It shall be ensured that the locking is safe and reliable.
7. The parts to be positioned must be verified with each other's position and direction signs during installation, and adjust the clearance to ensure the normal operation of the parts. If the piston and connecting rod should pay attention to the direction during assembly, the timing gear should ensure the correct timing of oil supply, ignition and gas distribution.
