Key Purchasing Considerations for Used Construction Machinery

• Engine Hours: The number of hours on the engine is the primary indicator of the machine's usage and overall condition.
• Undercarriage/Tires: For tracked machines, inspect the undercarriage (sprockets, rollers, chains) for wear, as it can be very expensive to replace. For wheeled machines, check the condition and remaining life of the tires.
• Hydraulic System: Check for any leaks in the hydraulic system (hoses, cylinders, pumps) and test all functions to ensure they operate smoothly and powerfully without hesitation.

Frequently Asked Questions About Heavy Equipment

How much wear is acceptable on an excavator's undercarriage?

As a general rule, an undercarriage is considered 50% worn when the track pin and bushing wear reaches a certain measurement specified by the manufacturer. Beyond 75% wear, replacement is typically imminent. It's best to have an experienced mechanic measure the undercarriage components to accurately assess their remaining life.

What is "blow-by" on a diesel engine?

Blow-by is the leakage of combustion gases past the piston rings into the engine's crankcase. You can check for it by removing the oil filler cap while the engine is running. Excessive smoke or pressure coming from the oil filler tube can indicate worn piston rings or cylinders, suggesting a potential engine rebuild is needed.
