EXCAVATOR INSPECTION
Excavator Inspection Guide
- Bucket: Make sure the bucket is the right size and type for your intended applications. Check for dents, damage, cracks or welds.
- Pins and Bushings: On the dipper and bucket pins and bushings, look for signs of regular greasing.
- Boom and Stick: Check for structural damage, cracks or welds on the boom and stick.
- Hydraulic Cylinders: Hydraulic cylinders should be smooth and blemish- free. Presence of oil indicates a scratched cylinder or the need for new packing inside the cylinder housing.
- Pins and Bushings: The boom arm pins and bushings should show evidence of regular greasing.
- Front Idler: The front idler should have some room left to extend forward on the track frame.
- Roller and Pin Clearance: Check clearance between the bottom of the guide rollers and the top of the track pins.
- Roller Frame: Inspect roller frame for cracks or welds.
- Pins and Bushings: Pins and bushings loosen up over time, causing the tracks to sag.
- Final Drive: Inspect final drive and sprocket for wear or leaks.
- Ring gear and Turntable: Check the ring gear and turntable for deflection. Rotate the cab and boom arm to detect any hesitation or roughness.
- Engine: Open the service access doors and inspect the engine, dipsticks and sight gauges. Check the hydraulic pump, hoses and valve bank for leaks.
- Cab: Inspect the overall condition of the cab. Note any broken or cracked glass, dented sheet metal or structural rust.
