What is a skid steer 500-hour service?
A 500-hour service is the second tier of scheduled preventive maintenance for a skid steer loader (bobcat). It is performed every 500 engine hours and is classified as an intermediate service. The procedure includes all 250-hour (minor) service tasks plus additional items: replacing the fuel filter, replacing the outer air filter element, replacing the hydraulic return filter, checking or replacing drive motor oil (chaincase), adjusting fan belt tension, load-testing the battery, torquing ROPS mounting bolts to specification, inspecting cab door and window latches, inspecting auxiliary hydraulic lines and taking a hydraulic oil sample for analysis. This service is typically performed by a qualified mechanic or fitter with the appropriate tools and torque specifications.
Benefits of scheduled skid steer servicing
- Reduced breakdowns: replacing fuel and hydraulic filters at 500 hours prevents contamination that leads to injector failure and hydraulic pump damage.
- Drive system longevity: checking and replacing drive motor oil (chaincase) at the correct interval prevents premature wear on chains, sprockets and drive motors.
- ROPS integrity: torquing ROPS mounting bolts to specification ensures the rollover protection structure performs as designed in the event of a tip-over.
- Predictive maintenance: hydraulic oil sampling detects metal particles, moisture and contamination early, allowing planned repairs instead of emergency breakdowns.
- Compliance: documented service records demonstrate that equipment is maintained to WHS standards, supporting insurance and regulatory obligations.
- Resale value: a complete service history with documented 250 and 500-hour services increases the machine's value at trade-in or auction.

Service actions included in the 500-hour procedure
This service procedure covers 10 additional service actions (on top of all 250-hour tasks) across 6 system areas:
- Fuel system: replace fuel filter element.
- Air intake: replace outer air filter element.
- Hydraulic system: replace hydraulic return filter, inspect auxiliary hydraulic lines, take hydraulic oil sample for analysis.
- Drive system: check or replace drive motor oil (chaincase).
- Engine: adjust fan belt tension.
- Electrical: test battery under load.
- Safety / structural: torque ROPS mounting bolts to specification, inspect cab door and window latches.
Fluid specifications
General fluid specifications for skid steer loaders. Capacities vary by machine size and manufacturer.
| System | Type / Grade | Approx. Capacity |
|---|---|---|
| Engine oil | 10W-30 or 15W-40 | 6 - 10 L |
| Hydraulic oil | ISO VG 46 (AW 46) | 40 - 60 L (system) |
| Coolant | 50/50 ethylene glycol | 8 - 15 L |
| Chaincase / gearbox | Manufacturer-specific | 5 - 10 L |
| Grease | EP2 lithium complex | As required |
Specifications are general guidelines. Always refer to the manufacturer's service manual for your specific make and model.
Parts and consumables
Have the following parts and consumables ready before starting the 500-hour service (in addition to all 250-hour parts):
- All 250-hour parts (engine oil, oil filter, grease, coolant)
- Fuel filter element - 1
- Outer air filter element - 1
- Hydraulic return filter - 1
- Drive motor / chaincase oil (if replacing) - 5-10 litres
- Oil sample bottle (hydraulic) - 1
- Rags, drip tray and waste oil container
Look up part numbers in the manufacturer's parts manual for your specific make and model before ordering.
How to perform a skid steer 500-hour service
- Complete the full 250-hour service procedure first. The 500-hour service is cumulative and builds on all 250-hour tasks.
- Replace the fuel filter element. Prime the fuel system if required by the manufacturer.
- Replace the outer air filter element. Inspect the inner safety element and replace if the restriction indicator shows red.
- Replace the hydraulic return filter. Take a hydraulic oil sample from the sample port before fitting the new filter. Label the sample with the machine ID, hours and date.
- Check the drive motor oil (chaincase) level and condition. Replace if discoloured, contaminated or due by manufacturer interval.
- Inspect and adjust fan belt tension to the manufacturer specification.
- Load-test the battery. Check and torque ROPS mounting bolts to the manufacturer specification.
- Inspect auxiliary hydraulic lines for wear or damage. Check cab door and window latches for secure operation.
- Start the engine and check for leaks, abnormal noises or warning lights. Record any defects or recommendations in the notes section.
- Set the next service due hours (next 250-hour and next 500-hour intervals). Sign off and update the machine's maintenance log.
In MapTrack, you can schedule services based on hour meter readings, get automatic reminders, complete service procedures on mobile and link every record to the machine. Book a demo to see how.

Skid steer maintenance follows a tiered schedule where each level includes all tasks from the level below. This is called carry-forward or cumulative servicing.
Engine oil and filter, grease points, drive chain tension, fluid levels, basic inspections. Estimated 1-2 hours.
500 hours - Intermediate service (you are here)
All 250-hour tasks plus hydraulic filter, fuel filter, air filter replace, drive motor oil, fan belt adjustment, battery load test, ROPS bolt torque, oil sampling. Estimated 2-3 hours.
In MapTrack, you can configure service schedules by engine hours and receive automatic alerts when each interval is due.
Frequently asked questions
- What is included in a skid steer 500-hour service?
- A 500-hour skid steer service is an intermediate service that includes all 250-hour tasks (engine oil and filter, grease points, drive chain tension, fluid levels, basic inspections) plus replacing the fuel filter, replacing the outer air filter element, replacing the hydraulic return filter, checking or replacing drive motor oil (chaincase), adjusting fan belt tension, load-testing the battery, torquing ROPS mounting bolts to specification, inspecting cab door and window latches, inspecting auxiliary hydraulic lines, and taking a hydraulic oil sample for analysis. It takes approximately 2 to 3 hours.
- How often should a skid steer be serviced?
- Skid steers follow a tiered service schedule based on engine hours. A 250-hour (minor) service covers oil, filters, grease points, drive chain tension and basic inspections. A 500-hour (intermediate) service adds hydraulic filter replacement, fuel filter replacement, drive motor oil check, fan belt adjustment, battery load test, ROPS bolt torque and oil sampling. Daily pre-start checks are performed by the operator before each shift. Always refer to the manufacturer service manual for your specific make and model.
- What additional parts are needed for a 500-hour service?
- In addition to all 250-hour parts (engine oil, oil filter, grease, coolant), a 500-hour service requires a fuel filter element, an outer air filter element, a hydraulic return filter, drive motor or chaincase oil (if replacing), and an oil sample bottle. Have rags, a drip tray and a waste oil container on hand as well.
