Bobcat T250 2003 Parts Catalog – Factory OEM Specifications

Bobcat T250 2003 Parts Catalog is the only parts reference you should trust when ordering components for your loader. I’ve seen aftermarket catalogs list the wrong filter because they misread the serial number break. This factory print covers S/N 5231 11001 & Above and S/N 5230 11001 & Above. Every part number is verified against Bobcat’s own engineering specs. No reprints, no copy.

Maintenance Items: Exact OEM Part Numbers

The first thing you see in this catalog is a full list of maintenance items. Engine oil filter (6678233), fuel element (6667352), inner and outer air cleaner cartridges (6681474, 6681475), hydrostatic element (6661248), battery (6665427), and multiple grades of motor oil and hydraulic fluid. Each entry has a page reference so you can drill down to the exploded view if needed. For example, the inner air cleaner cartridge points to page 199. That’s how a factory catalog works – it never leaves you guessing.

Service Schedule: 10, 50, 250, 500, and 1000 Hours

Page 4 lists the service schedule intervals. At 10 hours you check motor oil and grease fittings. At 50 hours you add hydraulic fluid. The catalog includes part numbers for each consumable at every interval. For the 1000-hour service, the catalog lists all the filters, oils, and hydraulic fluids you need, with part numbers and quantities. You’ll see the 55-gallon drum of hydraulic fluid (6563330) for large fleet operations. The greasing schedule is also included – general purpose grease (6658266) is indicated for all zerk fittings at every interval. This level of detail is what separates a factory catalog from a generic parts list. You won’t have to wonder which filter goes with the 250-hour service. It’s all laid out with OEM part numbers and quantities. The Bobcat T250 2008 Service Manual covers the repair procedures, but for parts ordering this catalog is the definitive source.

Why Not Use an Aftermarket Parts Lookup?

Aftermarket databases often combine multiple model years or skip serial number breaks. I’ve had a tech order a drive motor seal from a generic catalog that didn’t fit because the catalog used a superseded number without warning. This manual is the original factory print from Bobcat Company, 2003. It lists parts specifically for your serial number range. The Automotive Industry Overview on Wikipedia shows how standardized OEM documentation is across heavy equipment – but only if you have the genuine article.

361 Pages of Factory-Sourced Data

Every page is numbered and cross-referenced. The catalog includes exploded diagrams, part number tables with descriptions and remarks, and serial number applicability. You get the same information that a Bobcat dealer uses to order parts. Whether you need a new hydraulic hose or a complete engine gasket set, the part number is here. Notice the Remarks column in the part number tables. It tells you exactly where to find the detailed illustration. For example, the engine oil filter (6678233) has a remark ‘See Page 177’. That page shows the filter mounting, gasket, and related hardware. Without this cross-reference, you’d be hunting through the book. Also note the quantity column – some parts are sold in 6-packs or kits. The catalog makes it clear. Bobcat T3571, T3571L 2005 Parts Catalog – OEM Factory Specs is another example of the same quality documentation for a different model.

Serial Number Verification: Before You Order

Always check your loader’s serial number against the two ranges listed on the cover: S/N 5231 11001 & Above and S/N 5230 11001 & Above. Bobcat made changes during the 2003 model year, and using the wrong catalog can cost you a day of downtime. This manual explicitly marks which parts apply to which serial number range. I’ve seen techs skip this step and end up with a fuel element that didn’t match the housing. Don’t be that guy.

Audience Fit: Who Needs This Catalog

If you own a Bobcat T250 2003 loader, this is your parts bible. Fleet managers need it to keep maintenance consistent. DIY owners need it to avoid ordering the wrong part and paying return shipping. Professional technicians use it to verify supersessions before they open a box. The catalog is also useful for those restoring older equipment – it lists parts that may have been discontinued but can be cross-referenced to current equivalents. Heavy equipment documentation standards are discussed on Automotive Industry Overview. For parts ordering, get this catalog first.

Does this catalog include engine overhaul parts?

Yes, engine components are listed with OEM part numbers.

Can I use this to find the correct hydraulic filter?

Start with the Maintenance Items table on page 2. For hydraulic filter, locate item 5 – element hydrostatic #3 media, part 6661248. The catalog also cross-references fluid containers: 6563328 for 2.5 gal, 6722344 for 5 gal, 6563330 for 55 gal. Each has a page reference (page 314) for further detail. That eliminates ordering the wrong viscosity or capacity.

What serial numbers does this cover?

S/N 5231 11001 & Above and S/N 5230 11001 & Above.

Is this the same as the service manual?

No, this is a parts catalog only. It lists every OEM part but does not include repair procedures. For step-by-step service instructions, you need the Bobcat T250 2006 Service Manual.
