一、清洗外表冷再生机在施工过程中会有大量的灰尘落到再生机的表面，包括施工中沾污的油迹等污染物，影响外观事小，更为严重的是成为腐蚀的诱发因素。

　　1、 During the construction process of cleaning the exterior of the cold regeneration machine, a large amount of dust will fall onto the surface of the regeneration machine, including pollutants such as oil stains during construction. This has a minor impact on the appearance, but more seriously, it can become a triggering factor for corrosion.

　　1.清洗工程机械的柴油机、底盘、工作装置的外表,除垢、除油保持再生机的外观整洁。2.清洗时严禁用高压、高温的水枪来冲洗防水要求较高的部位（特别是电器部分），以免造成电器部分的损坏。清洗外表，是工程机械冬季保养要点之一。二、?保养转子及其罩壳和滑靴

　　1. Clean the exterior of the diesel engine, chassis, and working equipment of construction machinery, remove dirt and oil, and keep the appearance of the regeneration machine clean. 2. It is strictly prohibited to use high-pressure and high-temperature water guns to rinse areas with high waterproof requirements (especially electrical parts) during cleaning, in order to avoid damage to the electrical parts. Cleaning the exterior is one of the key maintenance points for construction machinery in winter. 2、 What? Maintain the rotor, its casing, and sliding shoes

　　1.检查转子是否有水泥结垢等，及时清理灰尘，对需要割除、焊接的刀具及时更换；

　　1. Check whether the rotor has cement scaling, clean the dust in a timely manner, and replace the cutting tools that need to be cut or welded in a timely manner;

　　2.清理转子罩壳上的灰尘，并在施工结束收车时将转子罩壳垫起地面5-10公分，防止雨雪的浸蚀；3.检查滑靴，对已经磨损的滑靴部分进行补焊，螺纹处应涂抹黄油防锈。三、减速机齿轮油的更换方式

　　2. Clean the dust on the rotor cover and place the rotor cover 5-10 cm above the ground to prevent erosion from rain and snow when the construction is completed and the vehicle is closed; 3. Check the sliding shoes and repair the worn parts with welding. Apply butter to the threads to prevent rust. 3、 Replacement method of gearbox gear oil

　　准备事项：

　　Preparation items:

　　1、场地:要求无尘硬化路面，面积应在200左右，是库房，但必须足够25吨的吊车的工作高度和半径。

　　1. Venue: Require dust-free hardened road surface, with an area of about 200 square meters, preferably a warehouse, but must be sufficient for the working height and radius of a 25 ton crane.

　　2、设施：25吨吊车一台（20吨也可以）。

　　2. Facilities: One 25 ton crane (20 tons is also acceptable).

　　3、配件：进口美孚齿轮油9升、卫生纸10卷、塑料带20个、废油桶2个、紧固胶262/340一支、密封胶587一支、黄油一袋，细线绳20米、?12 *45的带母螺栓30套、4*30开口销10个。

　　3. Accessories: 9 liters of imported Mobil gear oil, 10 rolls of toilet paper, 20 plastic tapes, 2 waste oil drums, 1 piece of fastening glue 262/340, 1 piece of sealant 587, 1 bag of butter, 20 meters of fine wire rope? 30 sets of 12 * 45 female bolts and 10 sets of 4 * 30 split pins.

　　4、工具：10、16、18、19、21、22、24、30套筒和扳手少一套、快速扳手及长、短接杆各一、加力杆一根、30的轮胎扳手、10毫米的内六角扳手、55的活口扳手两把、小号活口扳手一把、小号的老虎钳一把、手钳一把、一字螺丝刀一把、大小锤头各一、撬棍两根，配备气动扳手和气泵，能提率。（减速机油位及减速机油的检查：先切断电源，等待减速机冷却后打开放油螺塞，检查油是否充满，避免漏油，?取油样，检查油色泽及粘度指数，如果油明显浑浊，建议尽快更换。新减速机使用后（500-1000）小时更换新油（将内部污油冲干净），其后每使用1500小时需要更换油一次，但是在使用过程中，仍需要检查油的质量，若油有老化、变质情况必须随时更换。）

　　4. Tools: At least one set of 10, 16, 18, 19, 21, 22, 24, and 30 sockets and wrenches, one quick wrench and one long and one short connecting rod, one power bar, one 30 tire wrench, 10 mm hex wrench, two 55 adjustable wrenches, one small adjustable wrench, one small vise, one hand pliers, one Phillips screwdriver, one hammer head, and two pry bars. It is best to equip with pneumatic wrenches and air pumps to improve efficiency. (Inspection of gearbox oil level and gearbox oil: Cut off the power first, wait for the gearbox to cool down, open the oil drain plug, check if the oil is full to avoid oil leakage, take an oil sample, check the oil color and viscosity index. If the oil is obviously cloudy, it is recommended to replace it as soon as possible. After using a new gearbox (500-1000) hours, replace the new oil (flush out the internal dirty oil), and then replace the oil every 1500 hours of use. However, during use, the quality of the oil still needs to be checked. If the oil has aged or deteriorated, it must be replaced at any time.)

　　1、将设备启动移已选好场地，将转子罩弹簧销轴取出，再将转子放置点，切记不可悬置或有吃力现象，造成大臂油缸销轴取不出来，油管泄压易出危险。

　　1. Start the equipment and move it to the selected site. Remove the spring pin shaft of the rotor cover, and then place the rotor at the lowest point. Remember not to suspend it or make it difficult to remove the pin shaft of the boom oil cylinder, which may cause danger due to oil pipe pressure relief.

　　2、拆卸油管和转子马达的保护罩壳。

　　2. Remove the protective cover of the oil pipe and rotor motor.

　　3、将马达到工作泵的6根油管在大臂连接处全部拆卸开，并用卫生纸和塑料带将接口全部封紧，预防进入灰尘及杂物，并取下连接钢管。

　　3. Remove all 6 oil pipes from the motor to the working pump at the connection of the boom, and seal all interfaces tightly with toilet paper and plastic tape to prevent dust and debris from entering. Remove the connecting steel pipe.

　　4、卸掉马达上的螺栓，并取下马达，注意需要两个人必须轻拿轻放。

　　4. Remove the bolts from the motor and take off the motor, being careful that two people must handle it gently.

　　5、将转子罩壳所有的连接杆拆卸，取下销轴。

　　5. Remove all connecting rods of the rotor casing and remove the pin shaft.

　　6、将连接两个大臂与固定横杆上的螺栓拆卸掉，只留两边上面的4个。

　　6. Remove the bolts connecting the two large arms to the fixed crossbar, leaving only the four on both sides.

　　7、拆掉横杆和车体连接的4个螺栓，上下面做好标记，方便安装。

　　7. Remove the 4 bolts connecting the crossbar and the vehicle body, and mark the top and bottom for easy installation.

　　8、用吊车挂转子一侧的大臂处，另一侧挂马达后侧的销轴，先提升尽量向一侧移动，然后将两根钢丝绳均挂到出来的那一侧，拖外面。

　　8. Use a crane to hang the large arm on one side of the rotor and the pin shaft on the back of the motor on the other side. First, lift it up as much as possible and move it to one side. Then hang both wire ropes to the side where they come out and drag them outside.

　　9、卸掉滑靴，吊出转子罩。

　　9. Remove the sliding shoes and lift out the rotor cover.

　　10、卸掉大臂与横杆和转子的连接处的螺栓，吊出大臂，放置一边。

　　10. Remove the bolts at the connection between the boom, crossbar, and rotor, lift out the boom, and place it aside.

　　11、卸掉减速机固定螺丝，并用撬棍插入轴套压住，用吊车吊出减速机，放置一边，检查有无渗漏现象。

　　11. Remove the fixing screws of the reducer and insert a pry bar into the shaft sleeve to press it down. Use a crane to lift out the reducer, place it aside, and check for any leakage.

　　12、放开减速机的两个油堵，放净废油。因两个油堵成90度角，在加注新油时，减速机平放的基础上必须让注油孔在点，直到观察孔漏油为止，然后将油堵缠上生料带上紧，如油堵是无‘O’型圈的类型，需在生料带的外面涂抹密封胶，观察12小时后有无渗漏现象。

　　12. Release the two oil plugs of the gearbox and drain the waste oil completely. Due to two oil plugs forming a 90 degree angle, when adding new oil, the gearbox must be placed flat with the oil injection hole at the highest point until the observation hole leaks oil. Then, wrap the oil plug around the raw material belt and tighten it. If the oil plug is of the type without an O-ring, apply sealing glue on the outside of the raw material belt and observe for any leakage after 12 hours.

　　13、将以上步骤反之，安装完毕。在安装的过程中，大臂、马达、减速机的固定螺栓均需涂抹紧固胶，马达与减速机结合面涂抹密封胶。

　　13. Reverse the above steps to complete the installation. During installation, the fixing bolts of the boom, motor, and gearbox need to be coated with fastening glue, and the joint surface between the motor and gearbox needs to be coated with sealant.
