Honda BF40A4 spare parts: LHA, LHTA and LRTA catalogues
Identify the correct part number in the Honda BF40A4 catalogue
To find the correct part number, start with the exact catalogue for the Honda BF40A4 outboard engine. This family includes the LHA, LHTA and LRTA variants: select the one that matches your identification before viewing the parts.
Each catalogue provides access to exploded views and Honda spare-part references. Use the diagram for the relevant section to locate the assembly you need, then check the part number shown in the parts list.
The LHA, LHTA and LRTA codes are catalogue identifiers. They distinguish the Honda BF40A4 variants without needing to interpret their meaning. When years or serial ranges are shown in the catalogues, also check this information to avoid selecting the wrong part.
If in doubt, compare the complete catalogue code, the part description and its position on the diagram before choosing a part number.
