One end connection, slowly pulls up chain 6, passes through crankshaft sprocket 2, until the other end of chain 6, using clincher tool chain 6
Both ends be riveted together；
4, using sprocket wheel tightener adjustment tightener sprocket 5 chain tension, to meet assembly parameter；
5, jiggering carries out disassembly decomposition to chain 6 at riveting, pacifies on lifting lug in rack 3 to suitable position when tearing machine open
Chain block is filled, one end of chain 6 is tensed, slowly unclamping chain block is freely placed at chain 6 in base 1；
6, whole chain 6 is hung out out of rack 3, then individually carries out vanning shipping；
7,4 pairs of chains 6 of step 2-are repeated after complete machine shipping shipyard to reassemble.
Mode is shipped using the installation of above-mentioned marine diesel chain, there is following drawback:
1, disassembly dress is multiple repeatedly in rack 3 for chain 6, and inefficiency expends a large amount of manpower and material resources；
2, since 6 length of chain is larger, when being lifted by crane after rack 3 and base 1 are closed up, have to the sling height of lifting appliance
High requirement is required if lifting is not achieved in the lifting appliance in workshop, can not be operated；
3, a marine diesel usually has multiple rows of chain 6, using existing installation shipping mode, can only operate a row every time
Chain, whole diesel engine occupy the use time of a large amount of workshop lifting appliances, extend duty cycle；
4, during the lifting that chain 6 is dismantled repeatedly in rack, Yi Fasheng chain 6 swings the case where tapping sprocket wheel, causes
Keep components in rack impaired.
