The piston is determined according to the cylinder bore level of the garbage truck. The bore diameter of the cylinder is represented by numbers or letters and is generally located at the rear side of the cylinder. When using a new cylinder, check the bore level on the rear side of the cylinder and select the same piston level. When the cylinder is repeatedly used, the bore diameter is measured first, and the bore level is determined by comparing the measurement result with the bore diameter of the piston selection table. Finally select the same level of bore. Prior to installation, the piston rings should be carefully inspected and their models, specifications, and numbers should be checked. Piston rings and ring grooves should be kept clean. The rings should be painted with very little oil. When installing the garbage truck piston ring by hand, place the piston ring flat on the piston ring expander seat and install the piston rings in sequence. At the same time, the marked side of the cylinder should face upwards. The opening positions of the rings should be offset from each other in order to create a labyrinth channel to reduce the leakage of gas and oil. The position of the opening should be avoided in the direction of the piston pin and the direction of the lateral thrust. The combined oil ring is generally installed by hand, and the openings of the scraper ring and the wiper ring spring cannot be on the axis of the piston pin. Adjust the pound code so that its two ends are balanced. The scale value corresponding to the pound code is the elastic force of the piston ring. Hard-rail Horizontal Machine Tools The horizontal lathe is capable of performing operations such as turning internal and external cylindrical surfaces, conical surfaces, forming rotary surfaces and annular grooves, turning sections and various threads, drilling, reaming, tapping threads, sleeve threading and knurling. Although the automation level of an ordinary horizontal lathe is low with a relatively longer auxiliary time in the process; due to its wide range of processing capabilities and overall performance, this type of machine tool has become widely popularized within the machining industry. It is a quintessential representative of our machinery industry and an indispensable piece of equipment for any machining operation.

Garbage truck piston removal steps
Disassemble the piston as follows: drain the engine of the garbage truck. Remove the cylinder head from the cylinder block. Remove the oil pan and oil pump filter and main bearing cap reinforcement. Mark the cylinder number on all pistons, connecting rods and connecting rod covers with a pencil or quick-drying paint. Remove the connecting rod bearing cover. Install a rubber sheath on the threads of the connecting rod bolts to avoid damaging the journal bearing and connecting rod bolt threads when the connecting rod is removed. Before removing the piston from the cylinder, use tools to remove the coke from the top of the cylinder. Push the piston and connecting rod out of the upper end of the cylinder.
