What is included in an excavator 250-hour service?

A 250-hour excavator service is a minor service that includes draining and replacing engine oil (typically 15W-40), replacing the engine oil filter, inspecting or replacing the outer air filter, draining the fuel/water separator, checking coolant level, checking hydraulic oil level, inspecting belts and hoses, checking and adjusting track tension, greasing all boom, arm and bucket pins, greasing the swing bearing and slew ring, checking battery and electrical connections, testing safety devices (horn, reversing alarm, seatbelt), and inspecting structural components (boom, arm, bucket teeth, cutting edge). It takes approximately 1.5 to 2.5 hours.

How often should an excavator be serviced?

Excavators follow a tiered service schedule based on engine hours. A 250-hour (minor) service covers oil, filters, grease and basic inspections. A 500-hour (intermediate) service adds hydraulic filter replacement, fuel filter replacement, undercarriage wear measurement and valve clearance checks. A 1,000-hour (major) service adds hydraulic oil change, coolant flush, final drive oil, injector and turbo inspection. 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 oil goes in an excavator engine?

Most excavator engines use 15W-40 diesel engine oil meeting CI-4 or CK-4 specifications. Typical engine oil capacity for a 10-35 tonne tracked excavator is 20-30 litres. Some manufacturers specify different grades for extreme cold or hot conditions. Always check the service manual for your specific make, model and operating environment.

What is an excavator 250-hour service?

A 250-hour service is the first tier of scheduled preventive maintenance for a tracked hydraulic excavator. It is performed every 250 engine hours (or approximately every 4-6 weeks of full-time operation) and is classified as a minor service. The procedure covers engine oil and filter replacement, air filter inspection, fuel system maintenance, hydraulic system checks, track tension adjustment, greasing all pivot points and bearings, electrical system checks and safety device testing. Unlike a daily pre-start check (which confirms the machine is safe to operate), the 250-hour service involves actual maintenance actions: draining and replacing fluids, replacing filters, adjusting components and measuring wear. It is typically performed by a qualified mechanic or fitter, not the operator.

Benefits of scheduled excavator servicing

Reduced breakdowns: regular oil, filter and fluid changes prevent engine and hydraulic failures that cause unplanned downtime on site.
Extended component life: clean oil and correct lubrication reduce wear on engine, hydraulic pump, final drives and undercarriage components.
Lower repair costs: a 250-hour service costs a fraction of an emergency breakdown repair. Catching issues early prevents cascading damage.
Operator safety: inspecting safety devices, structural components and hydraulic hoses at regular intervals reduces the risk of on-site incidents.
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, 500 and 1,000-hour services increases the machine's value at trade-in or auction.

Service actions included in the 250-hour procedure

This service procedure covers 27 service actions across 7 system areas:

Engine: drain and replace engine oil (15W-40), replace oil filter, inspect air filter, drain fuel/water separator, check coolant, inspect belts and hoses, clean radiator fins.
Hydraulic system: check hydraulic oil level, inspect hoses, fittings and cylinders for leaks, check quick-coupler.
Undercarriage / tracks: check and adjust track tension, inspect track pads, rollers, idlers and sprockets.
Lubrication: grease boom, arm and bucket pins, swing bearing, slew ring gear and track adjusters.
Electrical: check battery terminals and charge, test all lights.
Safety devices: test horn, reversing alarm and travel alarm, check seatbelt, fire extinguisher and ROPS/FOPS structure.
Structural: inspect boom, arm and bucket for cracks, check bucket teeth and cutting edge, verify all guards and covers.

Fluid specifications

General fluid specifications for tracked excavators (10-35 tonne class). Capacities vary by machine size and manufacturer.

System	Type / Grade	Approx. Capacity
Engine oil	15W-40 CI-4 / CK-4	20 - 30 L
Hydraulic oil	ISO VG 46 (AW 46)	150 - 250 L (system)
Coolant	50/50 ethylene glycol	25 - 40 L
Final drive oil	80W-90 GL-5	4 - 8 L per side
Swing gear oil	80W-90 GL-5 or SAE 30	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 250-hour service:

Engine oil (15W-40 CI-4/CK-4) - 20-30 litres
Engine oil filter - 1
Outer air filter element - 1 (if replacing after inspection)
Fuel/water separator element - 1
EP2 grease cartridges - 2-4
Coolant (pre-mixed or concentrate) - as required for top-up
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 an excavator 250-hour service

Park the excavator on level ground, lower all attachments to the ground, engage the safety lock and shut down the engine. Allow the engine to cool before draining oil.
Record the equipment details and current hour meter reading at the top of the service procedure form.
Start with the engine section: drain the old engine oil, replace the oil filter, fill with new oil to the correct level, then inspect the air filter, drain the fuel/water separator and check coolant.
Check hydraulic oil level in the sight glass, inspect all hydraulic hoses and fittings for leaks, and check the quick-coupler.
Inspect the undercarriage: check track tension and adjust if needed, inspect pads, rollers, idlers and sprockets for wear.
Grease all specified points: boom, arm and bucket pins, swing bearing, slew ring gear teeth and track adjusters. Use EP2 lithium complex grease.
Check the battery, test all lights, test the horn and reversing alarm, check the seatbelt, fire extinguisher and ROPS/FOPS structure.
Start the engine and check for leaks, abnormal noises or warning lights. Check the oil pressure gauge and all instrument readings. 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.

Engine oil and filter, grease points, fluid levels, basic inspections. Estimated 1.5-2.5 hours.

500 hours - Intermediate service

All 250-hour tasks plus hydraulic filter, fuel filter, air filter replace, undercarriage measurement, valve clearance. Estimated 3-4 hours.

1,000 hours - Major service

All 500-hour tasks plus hydraulic oil change, coolant flush, final drive oil, swing gear oil, injector and turbo inspection. Estimated 6-8 hours.
