Here's a brief description of the FAA approved Terminology: Overhaul: disassembled, cleaned, inspected, repaired as necessary, and reassembled; and tested in accordance with approved standards and technical data, etc, etc. Note that if all parts meet service limits, nothing needs to be replaced other than non-reusable parts (gaskets, seals, lock washers, etc.). Rebuild: disassembled, cleaned, inspected, repaired as necessary, and reassembled; and tested to the same tolerances and limits as a new item, using new or used parts that conform to new limits or to approved over or undersizes. Zero Timed: A rebuilt engine may be used with a new maintenance record (zero timed) only if it was rebuilt by the manufacturer or by an agency approved by the manufacturer. > Follow-up question #2.

An engine overhaul (or rebuild) does not address accessories. It is common practice to overhaul (or rebuild) accessories in conjunction with the engine, but this is not addressed by regulations, only common sense.
