At the appropriate moment to track pin and pin set of double face In caterpillar pin and pin sets of wear in the process, from caterpillar has gradually been stretched, driving wheel and pin set of meshing bad, resulting in abnormal pin breakage and drive tooth surface wear, will cause a biker, flap, impact, greatly shorten the life span of the traveling mechanism. When still can't recover by adjusting the tension degrees pitch, you need to track pin and pin set, in order to get the correct track distance. There are two kinds of decision on site crawler pin and pin sets turned moment; One way is to check on crawler successively from 3 mm long time; Another way is to check fix the quotas for marketing set of wear outside diameter 3 mm.
Caterpillar to keep proper tension if excessive tension, guide wheel spring tension on the track pin and pin sets, cylindrical pin and pin in the round has been under high compressive stress, the pin and pin set of premature wear during operation, at the same time, guide wheel tensioning spring elastic also ACTS on the guide shaft and shaft sleeve, produce very big surface contact stress, which make it easy to guide wheel sets of ground into a semicircle, tracked successively is apart from the easy to spin, and can reduce the mechanical transmission efficiency, waste of the power of the engine to the drive wheels and track. If the crawler tension too loose, easy to track from the guide wheel and the roller, and caterpillar lose the right to, make the running track volatility, flap, impact, guide wheel and abnormal wear of wheel..
