Theory we will repair the excavator, but for the valve are familiar with, although this part is not big, once appear, fault and wear, will directly affect the engine, one of the most typical is the engine for carbon. Master macheng excavator repair shop today tells about excavator engine fault handling methods of carbon deposition. Carbon macheng excavator engine repair case analysis: CTP caterpillar engine parts below happened recently for the fault of the valve seat ring wear it with specific case analysis. Caterpillar inc. , 797, caterpillar engine accessories, accessories carter have seen the pictures, I believe you of the fault have a intuitive understanding: 1: by visible figure 1, 2, 3, cylinder valve seat ring has a different degree of wear and tear, 2 cylinder wear degree is bigger, the valve seat almost disappeared. 2: the wear of the valve seat for inlet valve seat, the exhaust valve seat not seen obvious wear and tear. Knowledge popularization: CTP caterpillar engine accessories 1: the valve is in the cylinder head up and down reciprocating movement to complete the exhaust work parts. Caterpillar inc. , 797, caterpillar engine accessories, accessories 2 carter: valve in the cylinder head valve seat ring joint, not only can up and down reciprocating motion, as well as on the valve seat ring with a certain direction, to remove the effect of carbon deposition.
