Exam 15: Engine Removal, Disassembly, Cleaning,

What should you do to engine coolant after draining if it is to be reused?

Which injector sleeve material is least likely to produce cylinder head leakage?

Technician A says that Ferrotherm articulating pistons are a good reuse bet providing they are properly inspected before reassembly. Technician B says that forged steel trunk Monotherm pistons are a poor reuse risk even when they appear OK on inspection. Who is correct?

Technician A says that when there is visible thrust surface wear on a diesel engine crankshaft, the recommended solution is to replace the crankshaft. Technician B says that when the oil seal surfaces are worn, a crankshaft can usually be repaired. Who is correct?

Technician A says that rod side play must be checked with thickness gauges on any rod that does not use fractured rod technology. Technician B says that cracked rod technology enables perfect cap to rod alignment so measuring rod sideplay on reassembly is not required. Who is correct?

What should be used to align the cylinder heads on an engine with multiple heads before torquing the cylinder head bolts?

When installing piston packs to a diesel engine, which of the following should be avoided whenever possible?

What would most likely result if an engine was reassembled with one conn rod with a weight class two increments over specification?

What should be used to lift a crankshaft from an inverted cylinder block?

When a flywheel housing measures out-of-spec while performing flywheel housing concentricity runout measurements, which of the following would represent the minimum level of repair required?

What would happen if you mismatched a cracked rod cap with the rod assembly?

While checking main bearing clearance on an inverted diesel engine, the strip of Plastigage under one main shows notably more squish than the remaining mains. What does this likely indicate on this main bearing?

When checking connecting rod side play, which of the following tools is required if you are using the recommended method?

When a flywheel housing is reinstalled to an engine cylinder block, which of the following is recommended?
