The reason is easy to damage the clutch release bearing Where is it? In practice, despite a strict asked the driver to drip once a day to release bearing oil, which not only complicated operation, and bearing still often damaged. The analysts believe that, due to the high temperature of the engine is transmitted to the release bearing, combined with high-speed rotating bearing also produces heat, oil under these conditions remain difficult in the bearings, work continuously at high temperatures, {TodayHot} and poor lubrication conditions This is frequently the cause of damage.
To solve these problems, have tested the heating within the bearing grease on, the grease penetrate into the bearing, after such treatment, the grease can be filled although bearing, but because of the grease structure by high temperature treatment of the destruction, big performance reduce the rate of using this method is not ideal, does not extend bearing life. We also used the tip to release bearing grease gun nozzle direct injection butter. Then install the car, was observed to detect, bearing life greatly extended. The oiling method received satisfactory results, but the operation is more complicated. And then explore where the engine disintegration, add butter, first try to succeed in the 475C engine, and then type in the 475C and 480,492 engines a trial, both received very good results. After repeated practice, improvements, lessons learned, and ultimately the formation of a relatively simple method of operation of oiling procedure is as follows:
(L) the disintegration of the engine is not oiling method first opens the clutch cover, release bearing wear concept check, if confirmed no damage or wear bearing no overrun, remove the clutch pedal, adjusting the link shaft pin bearing and the separation seat back to the last position, the bearing bore butter filling with beak grease gun, until the bearing oil spill, then rotate a little bit bearings, oiling again, repeat the above work, have a little butter until around bearing overflow, then bearing rotation, observe the fuel, bearing rotation if they feel there is resistance, proof has been filled with grease in the bearing. Then clear the release bearing housing throughout spilled a small amount of butter, to remove the pin and the clutch cover, etc. reassemble.
(2) the disintegration of the engine oiling method engine disintegration exposed bearings and bearing assemblies, to separate the bottom of the bearing inner ring with a small hole refueling beak grease gun, bearing grease overflow when rotating bearing until the bearing of a circle overflow can have butter.
After the above two methods treated within six months bearings can no longer refuel. The oiling method Hengshui train station after the trial, the mechanical integrity has improved significantly, and achieved significant economic benefits. Material cost savings; to improve the handling capacity, handling capacity can be increased each month 30t. This method has been in the promotion of other railway stations, have achieved better results. |
