Regulator Rubber Cap Rehlko-Kohler-Lombardini LGW/3LD/5LD/11LD/FOCS - ED0021450140-S

What it is for

The original Rehlko Kohler Lombardini rubber cap, part number ED0021450140-S, is a protective component used in the electrical connections of the alternator and voltage regulator system. It is intended for selected applications within the LGW, 3LD, 5LD, 11LD and FOCS engine ranges, depending on the installed electrical configuration.

The cap protects the regulator connection area, helping shield electrical terminals from dust, dirt and moisture. Maintaining suitable protection around electrical connections helps preserve the charging system wiring and reduce deterioration caused by exposure to external contaminants.

Part number ED0021450140-S is explicitly identified in the original Lombardini 11LD625-3 parts catalogue under the alternator section as a rubber cap. The same reference also appears in parts documentation for the 25LD engine family and the Ruggerini MD191, confirming its use in different Lombardini electrical charging systems.

Additional applications are associated with the 3LD and 5LD ranges and the specified LGW and FOCS families. As different alternators and regulator types may be fitted to engines within the same family, compatibility must be checked against the actual electrical assembly rather than the engine series alone.

Also identified by short reference 2145014, this cap is suitable for replacing cracked, deteriorated or missing rubber protection. It is supplied as a single protective spare part, not as a complete voltage regulator, alternator or wiring assembly. Before ordering, verify the connector design and the regulator fitted to the engine.
