Welfare Engine & Generator Parts FAQs
Which engine parts do you supply for welfare units?
We supply parts to suit a range of common welfare unit engines, including Kubota, Yanmar, Hatz, Isuzu, Perkins, Kohler and Lombardini applications. Always check compatibility with your unit before ordering.
How do I choose the correct generator parts?
The correct parts depend on the engine or generator fitted, the charging and battery setup, and the components already in place. Confirm compatibility with the existing unit before ordering replacements.
How often should welfare unit engines be serviced?
This depends on usage and operating conditions. Units that run frequently, or in dusty or demanding environments, may need more regular servicing than those used occasionally.
Why won't my generator start or hold charge?
Common causes include a flat or worn battery, a faulty alternator, a blocked fuel filter, or a fuel stop solenoid that isn't operating correctly. Checking these components first can help narrow down the fault.
What is the difference between an inverter and a battery charger?
A battery charger replenishes the battery, while an inverter converts stored battery power into a usable supply for equipment in the unit. Both play a role in keeping a welfare unit powered.
Why are air, fuel and oil filters important?
Filters protect the engine from contamination and support reliable running. Replacing them at the manufacturer's recommended intervals is an important part of routine servicing.
Can I buy individual generator parts rather than full assemblies?
In many cases, yes. Individual parts such as solenoids, starter motors and capacitors can often be replaced separately, depending on the engine or generator fitted.
When should welfare unit batteries be replaced?
Replace a battery if it no longer holds charge correctly, shows signs of damage, or fails to support reliable starting and running. Regular checks help catch issues before they affect the unit.
