OEM Replacement Parts
BUILT TO DROP IN AND GET YOU RUNNING AGAIN
When a critical part fails, every hour of downtime adds up. At Lindsay Machine Works, we build OEM replacement parts that drop right into your equipment, match the original material and tolerances, and ship on lead times designed for the real world. For more than 30 years, our Kansas City precision machine shop has helped manufacturers, contractors, and operators across the Midwest get their lines, fleets, and facilities back online quickly.
Whether you have an old print, a worn sample part, or just a broken piece sitting on your bench, our team can take it from there. We reverse engineer, machine, fabricate, and inspect each part in-house so you get a replacement that fits, performs, and lasts.
What We Mean by an OEM Replacement Part
An OEM replacement part is a component built to match the form, fit, and function of the original equipment manufacturer’s part. It is not a generic substitute. It is a true drop-in replacement, made to the same critical dimensions, materials, and finishes as the original.
That distinction matters. A part that looks close but is off by a few thousandths of an inch, or made from the wrong alloy, can cause premature wear, vibration, or another failure down the line. Our job is to make sure the replacement we deliver behaves exactly like the part it is replacing, or better.
We work from any of the following starting points:
- The original engineering drawing or CAD file
- A worn, broken, or sample part you send us
- A photo, sketch, or partial measurement set we build out together
If you do not have prints, our reverse engineering team can utilize multiple systems to capture the geometry, then produce clean drawings you can keep on file for future runs.
Why Manufacturers Choose Lindsay for OEM Parts Manufacturing
OEM parts manufacturing is a specialty, not a side service. The shops that do it well combine three things: deep machining capability, strict quality control, and a sense of urgency about lead time. We focus on all three.
Drop-in fit, every time
Every replacement part leaves our floor matched to the original print or sample. We hold tight tolerances on our 5-axis and 4-axis CNC mills, vertical mills up to 32 inches by 120 inches, and CNC turning centers up to 26 inches OD by 80 inches long. Larger work moves to our manual engine lathes, which handle parts up to 39 inches OD and 240 inches long, or to our vertical turning lathe up to 57 inches OD. If it spins, mills, grinds, or bores, we have a machine sized for it.
Material matching that protects performance
Using the wrong material is one of the most common reasons a replacement part fails early. We work in the full range of metals your equipment was originally built from, including:
- Carbon, alloy, and tool steels
- Stainless steel
- Aluminum
- Bronze and brass
- Titanium
- Engineering plastics
Material can be supplied by you or sourced through us, and we keep documentation so you know exactly what went into the part.
Fast, predictable lead times
Downtime is expensive, so we build our schedule around it. With more than 50 machines in a 25,000 square foot facility, we can flex capacity to slot in urgent replacement work without pushing other jobs off track. Most quotes go out quickly, and we are honest about lead time on day one. If a part is needed yesterday, tell us. We will tell you the fastest, most realistic path to get it in your hands.
