The original part number is retained. Common Caterpillar Number is the same recognized number with its hyphen removed, for example 3N-2886 → 3N2886. Letters, digits and leading zeros remain unchanged. This is a spelling variant, not a substitute part or fitment guarantee. Unrecognized formats are marked for verification. Original quantities and notes apply; quantities do not indicate stock. An em dash represents an empty source field. Original manual page references are retained as source references.
