bobcat 331 track

How to maintain the bobcat 331 track? 1. The sprocket should be installed on the shaft without skewing and swinging. The end faces of the two sprockets in the same transmission assembly should be in the same plane. When the center distance of the sprockets is less than 0.5m, the allowable deviation is 1mm, and the center distance of the sprockets is 1mm. When it is larger than 0.5m, the allowable deviation is 2mm, but the tooth surface of the sprocket is not allowed to be rubbed. If the deviation of the two wheels is too large, it is easy to cause the chain to separate and accelerate the wear. When replacing the sprocket, pay attention to checking and adjusting the deviation. 2. The tightness of the bobcat 331 track chain should be appropriate, too tight will increase the power consumption, and the bearing will be easily worn; the chain that is too loose is easy to jump off, the tightness of the chain is: lift or press from the middle of the chain, and the center distance between the two sprockets is about 2-3 centimeter.
