What is a scraper 250-hour service procedure?
A 250-hour service is the first tier of scheduled preventive maintenance for a wheel tractor-scraper (single or twin engine). It is performed every 250 engine hours and is classified as a minor service. The procedure covers engine oil and filter replacement for each engine, air filter inspection, fuel system maintenance, hydraulic oil level check, bowl cutting edge and end bit wear inspection, bowl/apron mechanism inspection, elevator or auger condition check (if fitted), greasing all pivot points, tyre pressure and condition inspection, brake inspection, transmission oil level check, and electrical and safety device testing. Unlike a daily pre-start check, the 250-hour service involves actual maintenance actions: draining and replacing fluids, replacing filters, greasing components and inspecting for wear. It is typically performed by a qualified mechanic or fitter.
Wheel tractor-scrapers are among the most productive earthmoving machines on large civil and mining projects, capable of self-loading, hauling and spreading material in a single pass. Because they operate at relatively high speeds under heavy load, the engine, transmission, hydraulic system and cutting edges are subject to significant stress. A disciplined 250-hour service programme catches developing issues early, maintains optimal fuel efficiency and ensures the scraper meets its production targets throughout the project lifecycle.

Benefits of using this scraper 250-hour service procedure
- Reduced breakdowns: regular oil, filter and fluid changes prevent engine and hydraulic failures that cause unplanned downtime on earthworks projects.
- Extended component life: monitoring cutting edge thickness and end bit wear allows planned replacement rather than emergency changes mid-shift.
- Lower repair costs: a 250-hour service costs a fraction of replacing a worn bowl, failed elevator chain or hydraulic pump.
- Operator safety: inspecting brakes, tyres, ROPS and safety devices at regular intervals reduces the risk of on-site incidents with these high-speed earthmoving machines.
- Compliance: documented service records demonstrate that equipment is maintained to WHS standards, supporting insurance and regulatory obligations.
- Resale value: a complete service history increases the machine's value at trade-in or auction.
- Predictive maintenance: oil sampling and wear measurement data collected during 250-hour services enables trend analysis that predicts component failures before they occur.

What to include in a scraper 250-hour service procedure
This scraper 250-hour service procedure covers 7 key areas:
- Engine(s): drain and replace engine oil (tractor engine, and scraper engine if twin-engine), replace oil filter(s), inspect air filter(s), drain fuel/water separator(s), check coolant level(s), inspect exhaust system and fan belts.
- Hydraulic system: check hydraulic oil level in sight glass.
- Bowl and cutting edge: inspect bowl cutting edge thickness and end bit wear, inspect bowl/apron mechanism (cylinders, pins, rollers), check elevator or auger condition (if fitted).
- Lubrication: grease all pivot points (hitch, bowl lift, apron, steering kingpins), grease elevator/auger bearings (if fitted).
- Tyres and brakes: check tyre pressures (4-6 tyres), inspect tyre condition, inspect service brakes and park brake.
- Transmission and driveline: check transmission oil level.
- Electrical and safety: check battery, test lights, horn, reversing alarm, check seatbelt and ROPS.
How to use this scraper 250-hour service procedure
- Park the scraper on level ground, lower the bowl fully, apply the park brake and shut down both engines (if twin-engine). Allow the engines to cool before draining oil.: Select a firm, flat area away from active haul routes. Lower the bowl cutting edge to the ground to relieve hydraulic pressure. Allow at least 15 minutes for engine oil to settle back to the sump before removing the drain plug.
- Record the equipment details and current hour meter reading at the top of the service procedure form.: Capture the asset ID, make, model, serial number, site location and current hour meter reading for each engine. Cross-reference the reading against the previous service record to confirm the correct 250-hour interval has elapsed.
- Start with the engine section: drain the old engine oil from the tractor engine, replace the oil filter, fill with new oil. If twin-engine, repeat for the scraper engine. Inspect air filter(s), drain fuel/water separator(s) and check coolant.: Use 15W-40 CI-4 or CK-4 diesel engine oil. Tractor engines typically hold 30 to 50 litres. Fill to the full mark on the dipstick and run for two minutes to prime the filter before rechecking. Inspect the outer air filter element and replace if visibly restricted. Drain the fuel/water separator bowl completely and check coolant concentration with a refractometer.
- Check hydraulic oil level in the sight glass. Inspect the bowl cutting edge thickness and end bit wear. Inspect the bowl/apron mechanism and elevator or auger (if fitted).: Verify hydraulic oil is between the minimum and maximum marks on the sight glass with the bowl fully lowered. Measure cutting edge depth at three points across the width and compare to the manufacturer minimum specification. Check the apron cylinders, pivot pins and rollers for leaks and excessive play. If the scraper has an elevator, inspect the flights, chains and sprockets for wear.
- Grease all specified pivot points: hitch, bowl lift, apron, steering kingpins and elevator/auger bearings.: Apply two to three pumps of EP2 lithium complex grease at each nipple until fresh grease appears at the seal. A typical scraper has 20 to 40 grease points depending on the model. Use the manufacturer grease chart to confirm all points are covered, including the hitch oscillation pins.
- Check tyre pressures at all positions and inspect tyre condition and tread depth. Inspect service brakes and park brake.: Scraper tyres operate at high pressures (typically 450 to 700 kPa). Use a calibrated tyre gauge and inflate to the manufacturer specification for the current payload. Inspect sidewalls for cuts and bulges. Check brake pad or shoe thickness against the manufacturer service limit and verify the park brake holds on a moderate grade.
- Check transmission oil level. Inspect exhaust system and fan belts. Check the battery, test lights, horn, reversing alarm, seatbelt and ROPS.: Check the transmission dipstick with the oil at operating temperature and the engine idling in neutral. Inspect the exhaust manifold and turbo piping for leaks or cracks. Check fan belt tension and condition for fraying or glazing. Verify battery terminal connections are clean and tight and that all safety devices function correctly.
- Start the engine(s) and check for leaks, abnormal noises or warning lights. Check all instrument readings. Record any defects in the notes section.: Run both engines for at least five minutes and monitor oil pressure, coolant temperature and charge indicators. Walk around the machine and check for oil, coolant or hydraulic fluid leaks. Listen for unusual knocking, whining or vibration from the engine, transmission or hydraulic pump. Record any findings or follow-up actions.
- Set the next service due hours. Sign off and update the machine's maintenance log.: Calculate the next 250-hour and 500-hour service due hours by adding to the current reading. Update the service sticker on the machine and record the completed service in the central maintenance system or asset management platform.

Back to download formHow often should you complete this service procedure?
Wheel tractor-scrapers should receive a 250-hour minor service every 250 engine hours, which equates to roughly every three to five weeks on a busy earthworks project running 10 hours per day, six days per week. A 500-hour intermediate service is due at every second interval, adding hydraulic filters, transmission checks and deeper component inspections. A 1,000-hour major service is typically required annually or at the manufacturer-specified overhaul interval.
Between scheduled services, operators should perform a daily pre-start check before each shift covering oil levels, tyre condition, cutting edge wear, lights and safety devices. Twin-engine models consume double the fluids and filters, so parts planning should account for both engines at every interval. Operating conditions such as abrasive soils, steep grades and high ambient temperatures may warrant shortened intervals. Always follow the manufacturer service manual for your specific make and model.
