RECOMMENDATIONS FOR DISASSEMBLING AND ASSEMBLING
Important
• To locate specific topics, the reader should refer to the index.
– Besides disassembly and reassembly operations this chapter also includes checking and setting specifications, dimensions,
repair and operating instructions.
– Always use original spare parts for proper repair operations.
– The operator must wash, clean and dry components and assemblies before installing them.
– The operator must make sure that the contact surfaces are intact, lubricate the coupling parts and protect those that are prone
to oxidation.
– Before any intervention, the operator should lay out all equipment and tools in such a way as to enable him to carry out operations
correctly and safely.
– For safety and convenience, you are advised to place the engine on a special rotating stand for engine overhauls.
– Before proceeding with operations, make sure that appropriate safety conditions are in place, in order to safeguard the operator
and any persons involved.
– In order to fix assemblies and/or components securely, the operator must tighten the fastening parts in a criss-cross or alternating
pattern.
– Assemblies and/or components with a specific tightening torque must initially be fastened at a level lower than the assigned
value, and then subsequently tightened to the final torque.
RECOMMENDATIONS FOR OVERHAULS AND TUNING
Important
• To locate specific topics, the reader should refer to the index.
– Before any intervention, the operator should lay out all equipment and tools in such a way as to enable him to carry out operations
correctly and safely.
– The operator must comply with the specific measures described in order to avoid errors that might cause damage to the engine.
– Before carrying out any operation, clean the assemblies and/or components thoroughly and eliminate any deposits or residual
material.
– Wash the components with special detergent and do not use steam or hot water.
– Do not use flammable products (petrol, diesel, etc.) to degrease or wash components. Use special products.
– Dry all washed surfaces and components thoroughly with a jet of air or special cloths before reassembling them.
– Apply a layer of lubricant over all surfaces to protect them against oxidation.
– Check all components for intactness, wear and tear, seizure, cracks and/or faults to be sure that the engine is in good working
condition.
– Some mechanical parts must be replaced en bloc, together with their coupled parts (e.g. valve guide/valve etc.) as specified
in the spare parts catalogue.
Danger
• During repair operations, when using compressed air, wear eye protection.
