Volvo EC240B: The Mid-Size Excavator Built for Heavy Duty Work
The Volvo EC240B stands as one of the most versatile mid-size excavators in the CE lineup. Rated at approximately 24 metric tons operating weight, the EC240B delivers genuine productivity across construction, quarrying, and demolition applications. With its D7E engine producing around 138 kW and a bucket capacity ranging from 0.7 to 1.5 m³, it handles demanding tasks with efficiency. Keeping this machine running at peak performance requires the right parts at the right time — and that’s exactly what VMP Spares stocks for the EC240B with over 2,000 verified OEM-spec components.
EC240B Serial Number Ranges and Model Variants
The EC240B was produced across multiple serial ranges. Understanding your machine’s serial number is critical for correct parts identification. The main production variants include the EC240BLC (Long Carriage), EC240BNL (Non-Level), and the EC240BPrime series. Always locate your serial number on the frame plate near the cab right-side door before ordering any parts.
| Variant | Serial Range | Production Years | Key Difference |
|---|---|---|---|
| EC240B LC | 10001– | 2004–2010 | Standard long undercarriage |
| EC240B NL | 15001– | 2005–2010 | Non-leveling boom option |
| EC240B Prime | 20001– | 2009–2012 | Enhanced fuel efficiency |
| EC240B LR | 25001– | 2010–2014 | Long reach configuration |
Hydraulic System Parts: Core of EC240B Performance
The EC240B hydraulic system operates at pressures up to 350 bar in the working circuits. The main hydraulic pump is a tandem piston pump driven directly from the engine. When hydraulic performance drops — slower cycle times, increased fuel consumption, or unusual noise from the pump — it’s time to inspect and potentially replace these critical components.

Undercarriage Components for EC240B
The EC240B undercarriage is designed for the machine’s 24-ton operating weight and sees heavy wear in abrasive ground conditions. Undercarriage wear directly impacts machine stability, tracking accuracy, and overall productivity. The standard track shoe width is 600mm, though optional wider shoes (700mm, 800mm) are available for soft ground. → Check all EC240B undercarriage parts in our shop for current stock:
| Undercarriage Part | Specs | Replacement Interval |
|---|---|---|
| Track chain assembly | 49 links / side | 3,000–5,000h depending on conditions |
| Track shoes (600mm) | Triple grouser, set of 49 | 2,000–4,000h |
| Top rollers | 2 per side, standard | 2,000–3,000h |
| Bottom rollers | 9 per side, standard | 2,000–4,000h |
| Drive sprocket | 17-tooth standard | Match with chain |
| Idler assembly | Front, with adjuster | Inspect every 500h |
| Recoil spring | High tension, 1 per side | Replace with idler |
Engine & Cooling System Parts
The EC240B runs on the Volvo D7E diesel engine — a proven inline-6 producing 138 kW. This engine is known for durability, but requires regular maintenance parts. The cooling system is critical in warm climates; coolant temperature should remain between 75–95°C at operating load. → Browse EC240B engine parts and engine mounting components in our catalogue:
| Engine Part | Part Number | Service Interval |
|---|---|---|
| Engine oil filter | VOE20998367 | Every 500h |
| Fuel filter primary | VOE20514654 | Every 500h |
| Fuel filter secondary | VOE20745605 | Every 1,000h |
| Air filter outer element | VOE11110215 | Every 500h or as indicated |
| Air filter inner element | VOE11110216 | Every 2nd outer filter change |
| Radiator core assembly | VOE14524558 | Inspect every 500h, clean fins |
| Thermostat | VOE20758808 | Replace if coolant overheating |
| Fan belt set | VOE11700006 | Inspect every 500h |
Electrical System & Cab Parts
The EC240B uses a 24V electrical system with a CAN bus control architecture introduced in later serial ranges. Common electrical failure points include the ICF (Instrument Control & Fuse) panel, harness connections near the slewing ring, and the engine ECU. → Browse EC240B electrical system parts and cables, fuses & relays for current stock:
