Parts buying guides

Use these practical guides to compare part conditions, check compatibility and prepare a clear enquiry.

Choosing and checking parts

• Used, new, rebuilt and remanufactured parts explained — Compare the four condition descriptions and the evidence to request before choosing a replacement.
• Buying used heavy equipment parts — Check identification, inspection records, included components and delivery terms before ordering.
• New machinery parts: genuine, aftermarket and new old stock — Ask about the manufacturer, specification, storage condition and contents of the quoted assembly.
• Buying rebuilt components — Assess the rebuild scope, reused and replaced items, measurements and test results.
• Remanufactured parts, core charges and exchange terms — Check the remanufacturing process, warranty provider and conditions for returning your old component.
• How to find the correct part for your machine — Use model, serial and part numbers to check component configurations, supersessions and compatibility.
