3、requirement was increasingly went up by human being. And it is regarded importantly by all the countries and become one important technology support to carry out the strategic of continual development[1,2].Owing to the m

4、al-conditions of operating and the high reinforcement, heavy duty caterpillar engines have a very short service life comparing with the civil vehicle. It is the unequal-life of the engine’s parts and working surfaces tha

5、t results in the failure of some parts and working surfaces and the engines goes to out-of-service. Short service life of engine and unconformity with the life cycle of vehicle had become a bottleneck to the maintenance

6、 in the armored cavalry[3].It is urgent for the ensuring and maintaining of armored equipment to start the remanufacturing of armored vehicle engine based on high technology for prolonging its service life. Notable benef

7、it in economy and military fairs will be gained by the same service life with the vehicle after remanufacturing of the engine. 2 feasibility analysisThe manufacturing technology used in the heavy duty caterpillar engine
