we all know who work with excavator excavator attachments often coupled parts are matching coordination work, such as engine fuel system of plunger, delivery valve, nozzle needle valve, distributing valve of the valve body and valve stem, etc. Today this article knowledge popularization, hope everybody can realize the coupling pieces of the key, improve their practical ability.
a lot of people have this question, complete use of excavator parts, one is broken, is it really necessary to complete replacement?

The answer is still not possible! Because after a period of time in use, the excavator parts between cooperate well, if the one damaged, when maintenance replacement, also should pay attention to assembly in pairs, so running in and cooperate with the degrees can always in the best state!
small make up have to repeatedly stressed a excavator accessories: such as engine connecting rod, piston, fan belt, high pressure tubing, excavator oil seal, etc. , the central rotary joint damage after the complete set of replacement cost is larger, it became a lot of people hesitate whether to don't complete the principal cause of replacement.
but also precisely because of this kind of parts at the same time using a set of accessories, so when the damage must complete replacement! Otherwise due to varying degrees excavators accessories quality difference is big, old and new, length size is differ, easily lead to engine operation instability, hydraulic system leak, severe load concentration, replacement of new parts easy to early damage! 。
some dig friends to save money, there is no change of complete sets of excavator accessories coupled parts, after a serious failure probability is very high. But this is not professional maintenance for the normal operation of the excavator, a hidden trap is likely to cause a big failure was not worth the cost!
