Reguladores

Official Lombardini regulators distributor in Spain

The correct operation of the charging system and engine speed control depend directly on the regulator's precision. As official distributors in Spain, we maintain centralized stocks of electronic voltage regulators and certified original mechanical regulation components, guaranteeing the operational stability of your agricultural or industrial machinery.

Types of Lombardini regulators available in stock

To meet the different repair needs of the brand's diesel engines, our technical catalogue classifies spare parts into two main families:

• Electrical voltage and current regulators: Electronic aluminum units with cooling fins, essential for stabilizing voltage from the alternator to the battery (available in common 5-pin and 6-pin versions for 12V and 24V systems).
• Mechanical speed regulators: Internal and external components responsible for managing the engine's revolutions per minute (RPM), such as governor springs, throttle linkages, counterweights, and yoke supports.

Compatibility with engine series and machinery applications

Our electrical and mechanical regulation components are manufactured to the manufacturer's exact tolerances to integrate seamlessly into the industry's most common engine ranges. We supply specific spare parts for the single-cylinder Lombardini 15LD series, the robust 9LD twin and three-cylinder engine range, classic Pasquali tractor series like 6LD, 3LD, and LDA, as well as the water-cooled LDW (FOCS) family.

How to identify the correct regulator for your engine?

For electronic current regulators, we suggest checking the number of connections (pins) engraved on the plastic base and the reference stamped on the metal casing of the damaged part. For mechanical speed regulator elements, due to variations based on application (walking tractor, dumper, or generator set), it is essential to locate the identification plate on the engine block and provide us with the engine model and serial number.

Frequently asked questions about Lombardini engine regulators

What are the symptoms of a faulty electrical current regulator?
The clearest signs of failure include a battery that does not receive a charge (the alternator does not send power), overvoltage that burns out bulbs or dashboard warning lights, or a battery that drains completely intermittently when the machinery is stopped.

Why does my Lombardini diesel engine rev up on its own?
When a diesel engine accelerates uncontrollably or suffers sharp fluctuations in revolutions, the cause is usually wear or breakage of the mechanical speed governor spring or seizing of the linkage connecting to the injection pump.

What advantages does the original replacement part offer compared to generic compatibles?
Original regulators ensure that the internal diode bridges and mechanical springs have exactly the factory resistance and calibration. Using cheap imitations often causes short circuits in the alternator or poor engine RPM control.
