SERIES 60 SERVICE MANUAL CLEANING Before removing any of the subassemblies from the engine (but after removal of the electrical equipment), the exterior of the engine should be thoroughly cleaned. NOTICE: The Series 60 engine is equipped with various sensors and other electronic components which may be damaged if subjected to the high temperatures in a solvent tank. Do not immerse any electrical components in a solvent tank. Care should be taken to ensure that all electronic components are removed from the various engine assemblies before they are immersed in a solvent tank. Refer to section 9for a description of these components.
Then, after each subassembly is removed and disassembled, the individual parts should be cleaned. Thorough cleaning of each part is absolutely necessary before it can be satisfactorily inspected. Various items of equipment needed for general cleaning are listed below. The cleaning procedure used for all ordinary cast iron parts is the same as the following cylinder block cleaning procedure. Any special cleaning procedures will be mentioned when required. Remove cylinder liners before putting the block in cleaning or descaling baths, to avoid trapping cleaning agents in block liner seating bores.
After stripping and before removing the cylinder block from the overhaul stand for cleaning and inspection, install the two metric eye bolts into head bolt holes at each end of the cylinder block. Remove all oil and water gallery and weep hole plugs to allow the cleaning solution to enter the inside of the oil and water passages. 1. Using two metric eye bolts installed in the head bolt holes at opposite ends of the block, and with a suitable lifting device and spreader bar, immerse and agitate the block in a hot bath of a commercial, heavy-duty alkaline solution. 2. Wash the block in hot water or steam clean it to remove the alkaline solution. 3.
If the water jackets are heavily scaled, proceed as follows: [a] Agitate the block in a bath of inhibited phosphoric acid. [b] Allow the block to remain in the acid bath until the bubbling action stops (approximately 30 minutes). [c] Lift the block, drain it and immerse it again in the same acid solution for 10 more minutes. Repeat until all scale is removed from the water jacket area. [d] Rinse the block in clear, hot water to remove the acid solution. [e] Neutralize the acid that may cling to the casting by immersing the block in an alkaline bath. [f] Wash the block in clean water or steam clean it. All information subject to change without notice. (Rev.
