How to maintain the road roller？

As construction machinery, the road roller has been widely used in various places. If the road roller is not maintained reasonably, it will cause a series of machinery failures. This article teaches you how to maintain the road roller.

Gearbox maintenance

1. The gearbox should be cleaned at least once a quarter. When cleaning, firstly in a hot state, unscrew the oil drain plug on the side of the gearbox, release the lubricating oil in the box, then screw on the oil plug, and pour kerosene into the box, and start the operation. Diesel engine, run the gearbox at low speed for 2-3 minutes, stop and drain the kerosene, clean the oil plug and screw it to the gearbox, (Note: the kerosene must be cleaned up to avoid the lubricating oil mixed with the residual kerosene and lose the lubricating effect), Then add new lubricating oil until the oil level reaches the marking line on the dipstick.
2. No. 20 gear oil for transmission.
3. It is necessary to check and adjust the positioning device of the speed change control mechanism and the reversing mechanism frequently to keep the gears in the proper position, so as to avoid the accident of bowing and disengaging.
4. Always pay attention to check the leakage of each seal of the gearbox, if the seal is damaged, replace it in time.
5. Always check the connection bolts between the gearbox and the frame, and tighten them if necessary, so as not to loosen and fall off.

Maintenance of the hydraulic system

1. Check whether the installation bolts of the filter, valve, da, oil pump, oil cylinder, etc. are loose, and whether there is oil leakage at each joint.
2. Observe the oil level gauge on the side of the fuel tank. When the hydraulic oil is too low, add the filtered hydraulic oil of the same grade.
3. The hydraulic oil tank is cleaned once every six months and the oil is changed. When adding or changing the oil, avoid mixing impurities and dirt into the oil tank. The new oil added or replaced must be filtered in advance.
4. No. 68 anti-wear hydraulic oil is used for hydraulic oil.
5. The hydraulic oil filter should be cleaned or replaced after every 500 hours of use.

Maintenance of vibrating wheel

1. The vibrating wheel is replaced with lubricating oil every 1000 hours. Check whether the vibrating wheel lubricating oil is leaking at any time; when checking the oil level, turn the refuelling C to the top, open the oil port, and let the oil leak until there is no leakage or less leakage.
2. Replace the lubricating oil of the vibrating wheel during maintenance, and pay attention to cleaning when changing the oil.
3. The lubricating oil is CD grade 30 diesel engine oil.
4. For the lubrication and maintenance of the walking bearing, after the whole machine has been used for an average of 20 days, a sufficient amount of calcium-based grease should be added to the corresponding oil cup position.

Main clutch maintenance

1. In addition to adjusting its operating mechanism at any time, the main clutch should also pay attention to checking and adjusting that the ends of its three release rods are in the same plane, and keep a certain gap (0.4~0.7mm) with the release bearing.
2. When the main clutch is engaged and disengaged, it should be smooth and gentle, and no excessive force should be used. When the clutch is engaged, the clutch pedal must be returned to its original position to fully engage the clutch. To disengage, when operating, it is necessary to prevent the clutch from being in a half-clutch and half-engagement state, so as not to burn out the clutch.
3. Check the main clutch frequently to avoid oil stains on the surface of the friction plate and pressure plate.

Side drive maintenance

Due to the low speed, large load, and easy contamination of dust, mud and sand, the side drive should always pay attention to check its lubrication, regularly remove the mud, sand and fine stone dust on the gear, and apply a new layer of calcium-based lubricant grease to avoid damage.

Battery maintenance

1. The battery has been used for a long time. If it is improperly used and maintained, it is common that the specific gravity of the electro-hydraulic decreases, the voltage during charging is extremely high, the voltage during discharging is extremely low, and white crystalline particles are found on the outside of the plate, forming the “battery” of the battery. The acidified battery can be restored to normal after 1-2 times of charging with a smaller current.
2. Check the charge status of the battery pack with an acid hydrometer to see if the battery is fully charged. The specific gravity of the electrolyte should be 1.28 (15oC) when fully charged. If the specific gravity drops to 1.2, you should borrow another power source to supply the battery group charging.
3. Under normal conditions, the generator of the diesel engine is enough to fully charge the battery, but in winter, the battery pack should be kept fully charged to avoid freezing.
4. In order to avoid the hardening of the battery electrodes and the formation of a sulfuric acid scale, the battery should not be in a discharged state for more than 24 hours. After charging, if it is not used temporarily, it should be charged once a week until the battery fully emits air bubbles.
5. The surface of the battery must be kept clean frequently. If there is dust or electrolyte flowing out, it is best to wipe it with a cloth soaked in ammonium chloride alcohol or a 10% ammonium sulfate solution.
