Guide to Checking Filters & Fluids on Cat® Equipment
Estimated read time: 3 minutes
One simple but important way to keep your Cat® equipment running smoothly is the daily walkaround or pretrip inspection. Fluids and filters are a significant part of your inspections, so we want you to know exactly what needs attention. This proactive approach not only helps minimize downtime but can also help extend the life of your machine, saving you time and money in the long run.
If you need replacement filters or fluids, you can order those at Parts.Cat.com. Enter your machine’s serial number to see the parts for your specific equipment.
Check out this video about filters and fluids and then keep reading below:
Prepare for Service
When you approach your machine, start your inspection from a distance. This bird's-eye view can help you spot anything unusual, such as fluid leaks on the ground. Once you're up close, begin your walkaround with the undercarriage, checking for leaks, excess debris and making sure all seals and bolts on the final drives are secure. If your equipment has rollers, keep those oil levels maintained.
Inspecting Air Filters
Your Cat equipment’s air filters protect the engine — and you. Here’s what to do on your daily walkaround:
- Cabin filters: Don’t forget to check these because they help protect you from harmful materials on the jobsite. The recirculating air filter is inside the cab, and the fresh air filter is on the side of your equipment. Replace these when they get dirty.
- Engine air filters: Pay attention to your engine life indicator. You’ll either have an electronic one, which means you get a notification on the screen in the cab, or a mechanical indicator which is near the filter itself.
- Engine air filter dust valve: Make sure the dust valve below the air filter housing is flexible and opens correctly to let out debris.
Remember, filters should be replaced, not cleaned. Cleaning can damage the filter media, allowing harmful debris to damage your engine over time.
Fluid Levels and Leaks
- Check your batteries for leaks or corrosion.
- Top off the windshield wiper fluid as needed.
- Keep all fluid fills and S•O•SSM analysis ports securely capped.
- Check oil levels, as applicable for your machine: engine, hydraulic, transmission, final drives, swing drive and differentials.
- Look for blockages, leaks or punctures in the cooler units and fins, and make sure your coolant level doesn’t get low.
- Inspect wheel motors and hydraulic components for leaks.
- Check all hoses, connections and fittings carefully.
- Drain the fuel-water separator, keeping an eye out for leaks around filters and lines.
