Need specs or a part number for your Bobcat S250? Start with your serial number — it is the difference between getting the right filter or seal and getting a box you have to return. This guide covers the essential specs and breaks down common replacement parts by system, so your lookup takes minutes instead of hours.
Bobcat S250 Specs at a Glance
Here are the core Bobcat S250 specs most owners search first, pulled from the factory specification sheet:

| Engine | Kubota V3800-DI-TE3, 4-cyl turbo diesel |
| Horsepower (SAE Gross / Net) | 75 HP / 72 HP |
| Displacement | 230 cu in (3.8 L) |
| Hydraulic Flow (Std / High Flow) | 20.7 / 36.7 GPM |

- Wheelbase: 48.3 in
- Ground clearance: 8.5 in
- Turning radius with bucket: 84.2 in
- Dump height: 99.1 in
- Dump reach at max height: 33.8 in
Standard buckets come in 68, 74, and 80-inch widths. Standard tires are 12-16.5, with 33×15.5-16.5 as an option.
Engine, Hydraulics, and Drivetrain
The S250 pairs a Kubota V3800-DI-TE3 diesel with a fully hydrostatic 4WD drive system. High idle sits at 2,400 RPM, peak torque hits 201.9 lb-ft at 1,500 RPM, and fuel use in heavy digging is about 3.2 gal/hr.
Fluid capacities to keep on hand:
- Engine oil with filter: 14 qt
- Coolant (propylene glycol mix): 4.3 gal
- Hydraulic reservoir: 4.7 gal
- Full hydraulic system: 13 gal
- Final drive: 11 gal
- Fuel: 23 gal
Hydraulic performance is where the S250 earns its keep. Lift and tilt cylinders share a 3.00-in bore and have quick cycle times: 4.4 seconds to raise, 3.2 seconds to lower, 2.6 seconds to dump, and 2.1 seconds to roll back. The high-flow option pushes 36.7 GPM to the auxiliary circuit, which unlocks planers, cold planers, larger trenchers, and stump grinders.
The drivetrain uses pre-stressed #120 HSOC endless roller chain — two chains per side, no idler sprocket, in a sealed case with oil lubrication. Chains do not need periodic adjustment, but chaincase oil should be checked at service intervals.
Breakout numbers for the S250: 5,000 lb lift, 5,000 lb tilt, and 5,500 lb push force. Bobcat S250 lift capacity is 2,500 lb rated per SAE J732, and 2,600 lb with the counterweight option.
Bobcat S250 Parts Lookup
Parts lookup goes faster when you sort by system instead of chasing single part numbers. Three details narrow any search: model (S250), serial number, and the specific system being serviced. The S250 had running changes across its production years, so the serial number keeps you on the correct side of any parts split.

Common Wear Signs & Service Tips
The S250 is durable, but wear items show up as hours climb. Matching a symptom to the right replacement part saves shop time.
Hydraulic System Issues
Slow lift arms, delayed tilt response, or rising oil temperature almost always point to hydraulic contamination or a restricted filter. Change the hydraulic filter, check fluid level, and confirm the reservoir is not aerating. If a fresh filter and proper fluid level do not help, then it makes sense to test the charge pump. A whining pump under load often comes from low oil level, a loose clamp, or a cracked suction hose before it turns out to be pump wear.
Starting and Electrical Problems
Rough startup or hard cranking in cold weather can trace back to the battery, the intake air heater grid, or a weak starter motor. The S250 uses a 950 CCA battery, so slow cranking on a healthy battery usually points to the starter or its wiring harness.
Undercarriage and Drivetrain Wear
Chain noise, backlash at the wheels, or clunking under direction changes shows up after several thousand hours of hard use. Since the chains do not adjust, replacement is the fix — and a good time to inspect axle seals and hub bearings while the case is open.
Attachment and Coupler Issues
Loose or wobbly attachments trace back to worn Bob-Tach bushings. These are inexpensive, easy to replace, and a tight Bob-Tach protects the attachment interface from long-term damage.
Cooling System Failures
Overheating, cab heater trouble, or coolant loss points at the cooling system. A failing water pump shows up as coolant weep at the pump housing, climbing temperatures under load, or a rough belt path near the front cover. Replace it along with the thermostat and hoses to avoid a second teardown.
Quick Reference: Common S250 Wear Items & Intervals
| Part | Typical Interval | Notes |
|---|---|---|
| Engine oil + filter | 250 hr | Use 15W-40 diesel oil |
| Hydraulic filter | 500 hr (first at 50 hr) | 3-micron synthetic media |
| Fuel filter | 500 hr | Water separator drained daily |
| Air cleaner | Inspect daily, replace as needed | Primary + safety element |
| Chaincase oil | Check yearly, change per manual | 11 gal per side |
| Bob-Tach bushings | Inspect at 500 hr | Replace at first sign of slop |
| Drive belt | Inspect at 250 hr | 3-year belt warranty was factory offer |
Final Words
The Bobcat S250 is easier to maintain when you keep the main specs and your serial number close by. If you know the machine’s engine, hydraulic flow, rated capacity, and pressure figures, parts lookup gets much simpler. For common replacement parts like filters, seal kits, starters, water pumps, and other service items, FridayParts carries a wide range of aftermarket options for the S250 and many other equipment models.
