Caterpillar 245 buying guide power reach and fit

The Caterpillar 245 is a large excavator built for mass earthmoving and heavy trenching. It carries an operating weight of 60548 kg (133486 lbs) and net power of 242 kW (325 HP) from a Caterpillar 3406 engine.

Reach, depth and hydraulic muscle define its production. The 245 digs to 789 cm (311 in.), reaches 1249.7 cm (492.0 in.) along the ground, and loads at up to 804.7 cm (316.8 in.). Buckets span 1.5 to 2.9 m2 (2.0 to 3.8 cu yds) with a reference size of 1.9 m2 (2.5 cu yds). Hydraulic pump flow is 893 LPM (236.2 GPM) with relief at 310 Bar (4500 psi).

Production numbers you can plan around

The Caterpillar 245 brings deep dig capability. Maximum digging depth is 789 cm (311 in.). Vertical wall digging depth is 533.4 cm (210.0 in.), which helps for clean utility trenches and basement digs without extra sloping. The machine reaches 1249.7 cm (492.0 in.) along the ground, so you can cast spoil back from the trench or load trucks parked a safe distance away.

Loading height matters when you match to trucks. With a max loading height of 804.7 cm (316.8 in.), the 245 can top off most on-road and off-road bodies without crowding. Swing speed is 4.8 RPM. That rotational rate supports steady cycle times on mass excavation and load-out work when paired with the bucket size that fits your material.

Travel speed is 3.1 km (1.9 mph). Plan moves on site rather than long roading. Ground pressure is 82.0 kPa (11.9 psi), which helps on soft or wet ground compared to narrower-shoe machines. For trenching, the 789 cm depth and 1249.7 cm reach pair well with the 1.5 to 2.9 m2 bucket range so you can pick capacity to keep the cycle in balance.

Powertrain and hydraulics details

Power comes from a Caterpillar 3406, turbocharged, with net power at 242 kW (325 HP), gross power at 250.8 kW (336.3 HP), and a rated speed of 2100 RPM. Displacement is 14600.9 cc (891 cu. in.). That big displacement with turbocharging supports strong torque at working rpm. Electrical is 24 V with a 35 A alternator, which is common for running machine electronics and lighting.

The hydraulic system is sized for heavy duty digging and loading. Pump flow is 893 LPM (236.2 GPM) and the relief valve pressure is 310 Bar (4500 psi). System capacity is 729.1 l (192.6 gal). Together, those numbers indicate strong oil delivery and pressure for bucket, boom and stick functions. Swing drive capacity is 35.2 l (9.3 gal), which is a service point to watch on an older large excavator.

Cooling capacity is 77.6 l (20.5 gal), and engine oil capacity is 36.3 l (9.6 gal). Fuel capacity is 597.3 l (157.8 gal), so you can plan long shifts without refuel breaks on most sites. Operating voltage is 24 V, which helps with reliable starts and stable control circuits on a large machine.

Size, undercarriage and ground conditions

The Caterpillar 245 is a big platform. Overall length is 1353.3 cm (532.8 in.) and overall width is 362.7 cm (142.8 in.). Cab height is also 362.7 cm (142.8 in.). Check low bridges and power lines when you move it. Ground clearance is 76.2 cm (30.0 in.), which helps over rock and site debris.

Track gauge is 286.5 cm (112.8 in.), shoe size is 76.2 cm (30.0 in.), and there are 45 shoes per side. That wide stance and wide shoes spread the 60548 kg operating weight, resulting in the listed 82.0 kPa (11.9 psi) ground pressure. If you work in soft clay or wetlands, that ground pressure figure helps you predict flotation and rutting against your site conditions.

Removal counterweight clearance is 109.7 cm (43.2 in.). That spec matters for service and transport. Drawbar pull is listed at 44.725 kg (98600 lbs). Use that figure only as a reference and confirm the rating in the documentation that comes with the specific machine you inspect.

Buckets and material fit

Bucket capacity drives production and ground conditions. The Caterpillar 245 supports a minimum bucket of 1.5 m2 (2.0 cu yds), a reference bucket of 1.9 m2 (2.5 cu yds), and a maximum bucket of 2.9 m2 (3.8 cu yds). Use the smaller end of that range for dense material or tight trench work. Use the larger end for common earth and load-out where boom and stick geometry let you fill at the listed 893 LPM flow and 310 Bar system pressure without stalling the hydraulics.

Match your planned cut height to the 804.7 cm maximum loading height. For truck match, set the truck body height and sideboard height against that spec, and pick the bucket that balances pass count and fill factor. For trenching to 789 cm depth, a 1.5 to 1.9 m2 bucket often helps manage spoil placement under the 1249.7 cm reach along ground. For stockpiling or mass excavation, the 2.9 m2 bucket can shorten the pass count if the material allows it.

What to check before you buy

Start with the engine. The 3406 should start clean and pull smoothly to its 2100 RPM rated power. Listen under load for steady turbo whistle on the turbocharged setup. Check for blowby at the breather and look for oil in the intake plumbing. Verify the 24 V electrical system charges at the alternator’s 35 A rating and holds voltage at idle and high idle.

Hydraulics come next. Warm the oil and cycle all functions. Controls should respond quickly with the 893 LPM flow and hold steady without chatter when you crowd into a pile at the 310 Bar relief setting. Inspect the main pump and valve banks for leaks. Look over hoses to the boom, stick and bucket, and the swing motor lines. Check the hydraulic tank condition. The system capacity is 729.1 l, so contamination can be costly to correct on a large reservoir if water or debris gets in.

Test swing and travel. Time a full swing and compare to the 4.8 RPM spec. Travel the machine on level ground and confirm it attains the listed 3.1 km (1.9 mph). Listen for final drive noise. Check the swing bearing for play by lifting the front on the bucket and rocking the house, then inspect grease condition. Verify the swing drive oil is clean and at the 35.2 l capacity.

Inspect the undercarriage carefully. Confirm 45 shoes per side and shoe size at 76.2 cm. Measure track gauge at 286.5 cm. Look for bent shoes, loose bolts and uneven wear. Ground pressure is 82.0 kPa (11.9 psi), so match the shoe type and condition to your soil needs. Check carrier and bottom rollers and idlers for leaks.

Check structure and geometry. Measure boom and stick reach to ensure it can meet the 1249.7 cm along-ground reach and 789 cm max digging depth. Confirm max loading height near 804.7 cm. Inspect the counterweight area. The removal counterweight clearance is 109.7 cm, so check for damage that could complicate removal. Verify the drawbar pull rating in the machine manual or on the data plate against the listed 44.725 kg (98600 lbs).

Fluids and cooling. Verify engine oil at 36.3 l capacity, cooling system at 77.6 l, and fuel tank at 597.3 l. Look for fuel tank rust or algae if it sat. Pressure test the cooling system and inspect cores and hoses. Check for hydraulic oil aeration after a work cycle. Confirm the alternator charges and all 24 V circuits operate, including lights and safety devices.

Who the Caterpillar 245 suits

Choose the Caterpillar 245 if you move bulk material, dig deep utilities, or load trucks all day. The 60548 kg operating weight, 242 kW (325 HP) net power, and 893 LPM hydraulic flow suit mass excavation and steady production. The 789 cm digging depth and 1249.7 cm along-ground reach cover many foundation, trench, and pond builds. Buckets up to 2.9 m2 let you push yardage when the material allows. The 804.7 cm loading height pairs with tall bodies for efficient load-out.

If your work needs soft-ground access, the 82.0 kPa ground pressure with 76.2 cm shoes can help. If your site has tight access, check the 362.7 cm width and 362.7 cm cab height against gates, utilities and transport routes. With a 3.1 km travel speed, plan moves and swing-dump cycles rather than long drives. Large tank and system capacities, including 597.3 l fuel and 729.1 l hydraulic oil, support long shifts when you schedule maintenance.

Decision takeaway: buy this machine if you need a large excavator with 325 HP, 789 cm dig depth, 1249.7 cm reach, and up to 2.9 m2 buckets to move serious yards with steady cycles. If your jobs demand faster travel or a smaller footprint than 362.7 cm wide, step down in class instead.
