Shanghai Automobile Sales Co., Ltd. Tiancheng era tells you ten heavy truck maintenance bogey five, are not allowed to avoid measuring cylinder gap measure, the provision to the long axis of the ellipse gap prevail, that measure piston skirt piston pin hole perpendicular to the direction of clearance. Therefore, when measuring cylinder gap should be measured in the direction perpendicular to the piston skirt piston pin hole. 6, avoid open flame heating piston when installing piston pins, piston placed in hot oil can be uniformly heated to slow expansion, must not use direct flame heating. Welcome to inquire! Shanghai Automobile Sales Co., Ltd. Tiancheng era tells you heavy truck maintenance matters (six) 6, avoid open flame heating piston piston and piston pin is due to the interference fit, so when installing the piston pin Shan de tractor, you should make Pistons thermal expansion, then Shanghai, Shantou de tractor offer, some maintenance personnel will be placed on the piston direct flame heating, this approach is very wrong Shan de tractor dealers, because each part of the piston uneven thickness, would not the same degree of expansion and contraction Shanghai Shantou de tractor company, flame heating causes the piston uneven heating, prone to distortion; piston surface will be attached to the charcoal, reduce the life of the piston. If the piston reaches a certain temperature, natural cooling, the microstructure and wear resistance will be damaged greatly reduced, its life will be significantly shortened. When installing piston pins, piston can be placed in the hot oil evenly heated to slow expansion, must not use direct flame heating. Welcome to inquire!
