The importance of contamination control in an engine room disassembly cannot be underestimated to prevent warranty comeback.

How engine parts are cleaned in the Marine, Transportation and Mining Industries is critical to avoiding costly expenses should an engine be contaminated with particles of dirt or grease. There are a number of variables that specialist engine workshops can take to control contamination and assure a good contamination rating. 

Firstly, engine components need to be washed down prior to entering the disassembly area. This will keep the majority of the dirt, grease and other contaminants from entering the workshop. 

Then, each engine part should be washed down with an automatic washing system and rinsed. A cleaning solution is used in the high pressure washer, then the rinse cleans all the soap and remaining dirt from the cavities. Automatic parts cleaners are more productive and typically more consistent than manual cleaning.  A rust inhibitor is then applied to prevent rusting. The end result before re-assembly must be a clean part with the proper amount of rust inhibitor applied. 

Finally, to prevent warranty comeback, operators, supervisors and management need to realise, understand and control all of the processes that may cause contamination.
