The reason is easy to damage the clutch release bearing Where is it? In practice, despite a strict requirements of internal combustion forklift driver release bearing drip once a day to oil, which is not only complicated operation, but still often bearing damage. The analysis that, due to the high temperature of the engine is transmitted to release bearings, combined with high-speed rotating bearings also generate heat, oil under these conditions is difficult to remain in the bearing, bearing work continuously at high temperatures, and poor lubrication conditions, which is frequent causes of damage.
In response to these problems, also experimenting with heating the grease on the bearings, the grease soaked into the bearing, so that after treatment, although can be filled with grease bearings, but because the grease structure by heat treatment after the destruction, big performance magnitude lower, using this method is not ideal, does not extend bearing life. We have to use a sharp separation of bearing grease gun nozzle direct injection butter. Then installed on the car, has been observed to detect, bearing life greatly extended. The oiling method received satisfactory results, but the operation is more complex. And then explore the disintegration of the engine is not the case, add the butter, first try to succeed in the 475C engines, and then type in the 475C and 480,492 engines a trial, both received very good results. After repeated practice, improve, lessons learned, and ultimately the formation of a relatively simple oiling method of operation, the specific process is as follows:
(L) without disassembly of the engine oiling method first open clutch cover, the concept of separation of bearing wear check, if confirmed bearing no damage or wear is not exceeded, then remove the clutch pedal, adjust the linkage pivot pin, so that separation of the bearing and seat back to the last position, the bearing bore butter filling with needle nose grease gun until the bearing oil spill, and then slightly rotate about bearings, grease again, repeat the above work until around the bearing has a little butter overflow, then bearing rotation, observe the oil, if they feel bearing rotation resistance, that they have filled with grease in the bearing. Then clear separation of a small amount of spilled everywhere bearing butter, to remove the pin and reassemble the clutch cover and so on.
(2) engine disintegration disintegration of the engine oiling method exposed release 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 bearing a circle has a butter overflow can.
After processing the above two methods, within six months can no longer refuel release bearing.
