Used Generators & Engines vs. New: What’s Right for You?

Choosing between a new or used generator or engine is a crucial decision influenced by your specific needs and budget. From powering heavy equipment to providing emergency backup, understanding the benefits and drawbacks of each option will help you make an informed choice.


New Generators

Benefits of Buying New

  • Warranty: New generators come with manufacturer warranties, typically lasting 1–2 years.
  • Reliability: Guaranteed factory performance with no prior usage.
  • Peace of Mind: Backed by the manufacturer for defects or operational issues.

Drawbacks of Buying New

  • Higher Cost: New units are substantially more expensive than used ones.
  • Limited Availability: Larger units may have longer lead times due to production schedules.

Ideal For:

  • Companies with time to wait for delivery.
  • Users seeking the security of a warranty.

Used Generators

Benefits of Buying Used

  • Cost Savings: Often up to 50% less than new generators.
  • Immediate Availability: Ready for purchase and shipment with no production delays.
  • Proven Durability: Name-brand industrial generators are built to last, and many low-hour units have significant operational life remaining.
  • Backup Units: Used standby generators are typically lightly used, offering excellent value.

Drawbacks of Buying Used

  • Uncertainty: Previous usage and condition depend on the seller’s word.
  • Limited Warranty: Most used units do not include a warranty unless sold by a reputable dealer.

Recommendations

  • Always buy from established sellers with technical expertise and testing facilities.
  • Look for low-hour units with detailed test certifications and maintenance histories.

Surplus Generators

What Are Surplus Generators?

Surplus generators are new units sold at a discount because they were overstocked or no longer required by the original buyer.

Benefits

  • Lower Cost: Typically more affordable than new units.
  • Unused Condition: Surplus units often have no operational hours.
  • Immediate Availability: No production lead times.

Drawbacks

  • Price Proximity: May still be close to new generator prices, making used options more cost-effective.

Generator Ends

Importance of Generator Ends

  • Voltage Regulation: Essential for stable power output, especially for sensitive equipment like computers.
  • Cost Savings: Used generator ends offer significant cost reductions while meeting performance needs.

Rebuilt Diesel Engines

Benefits of Rebuilt Engines

  • Cost Efficiency: Provide “like-new” performance at a fraction of the price.
  • Thorough Rebuilding Process:
    • Complete disassembly and cleaning.
    • Inspection, repair, and testing of components.
    • Replacement of consumable parts (bearings, seals, gaskets, etc.).
    • Dynamometer testing for performance validation.

Considerations

  • Ensure the seller is reputable and has the expertise to rebuild engines to factory specifications.
  • Rebuilt engines are ideal for industrial applications requiring cost-effective solutions.

New vs. Used: Summary

Why Choose Used, Rebuilt, or Surplus?

  • Better Value: Substantial cost savings compared to new units.
  • Proven Performance: Many used units, especially low-hour standby generators, have minimal wear.
  • Quick Turnaround: Avoid the delays associated with new generator production.

When to Choose New

  • If a manufacturer warranty is essential.
  • For companies with the budget and time to wait for delivery.
