Here are some common maintenance tasks you can perform to keep Komatsu bulldozer parts running smoothly:
Change the engine oil and oil filter regularly.
Follow the recommended intervals in the operator’s manual. Dirty or stale oil cannot lubricate and cool the engine effectively.
Inspect and replace air filter elements.
The air filter prevents debris from entering the engine. A clogged air filter reduces air flow and power.
Check and refill radiator coolant.
The coolant prevents the engine from overheating. Make sure there are no leaks in the radiator, hoses or water pump.
Clean radiator fins.
Dust and debris clogging the radiator fins prevent proper cooling and overheat the engine. Use compressed air to blow out any dirt.
Check and tighten critical bolt connections.
Loose or missing bolts can lead to structural damage or component failure. Tighten bases, mounts, sprockets, etc. as needed.
Replace hydraulic filter and oil.
Hydraulic filters remove contaminants from the hydraulic fluid and oil. Clogged filters reduce flow and power and damage hydraulic components.
Replenish grease in all grease fittings.
There are grease points throughout the machine that require lubricating grease to prevent friction and wear. Pump grease through all fittings.
Check dozer blade lift linkages and pivot points.
Ensure all pins and bushings are present and not worn out or damaged. Worn linkage parts compromise blade control and can allow the blade to drop unexpectedly.
Inspect tracks, idlers and sprockets.
Check for excessive wear, bent or broken parts. Worn tracks reduce traction and stability. Replace parts as needed.
Test all functions including blade lift, tilt, Winch and brakes.
Ensure all levers, pedals and controls operate smoothly without binding or sticking. This checks for any issues with the hydraulic system, linkages or mechanical components.
Perform scheduled belt replacement and tension checks.
Belts drive components like alternator, power steering, tensioners, etc. Loose, cracked or missing belts shut down power and functionality.
Check safety interlocks and switches.
All interlocks should only allow machine functions when conditions are safe. Faulty interlocks put the operator and others at risk of injury. Test and repair as needed.
