Bobcat 853 Parts Catalog – Factory OEM Specifications

Let me be straight with you. You are trying to rebuild a loader, and you need a part number that matches what came off the machine. Aftermarket parts lists will waste your time — wrong numbers, missing details, diagrams that don’t line up. This is the real Bobcat 853 Parts Catalog, direct from the manufacturer. 316 pages of exploded views, part numbers, and cross-references. I have torqued bolts for twenty-eight years, and I can tell you: the only way to get a job done without returns or rework is to start with the factory document. This one covers everything from the Fuel system to the Brake assembly and every Cylinder in the hydraulic circuit.

Main Frame and Operator Cab Coverage

Pages 12 through 35 break down the main frame, operator cab, seat and seat bar, rear door, lift arm, Bob-Tach, panels, and the fuel system. Fuel system parts are on pages 34-35 — tank, cap, sender, lines. If you need a fuel tank gasket or the sending unit, you will find the exact Bobcat part number. No cross-referencing a generic number that might fit. The cab section shows every panel, latch, and window. Aftermarket catalogs lump these together; this one separates them by serial number range (S/N 5084 11001 & Above, S/N 5097 11001 & Above). Pay attention to that — your 853 might differ.

Drive System and Disc Brake Assembly

Drive system starts on page 36 and runs through axle on page 43. You get the drive train, gearcase, disc brake, and axle. The disc brake section on pages 40-41 is critical. If you are replacing brake discs or seals, you need the OEM part number. Aftermarket catalogs often consolidate brake components across models, but the Bobcat 853 uses specific friction discs and steel plates. One wrong part and you are pulling the gearcase again. This catalog lists every washer, spring, and O-ring. Use it.

Hydraulic Cylinder: Detailed Breakdowns for Tilt and Lift

Hydraulic system sections run from page 44 to 69. Tilt cylinder parts are on pages 48-51; lift cylinder parts on pages 52-55. Each cylinder is shown with seals, pistons, rods, and end caps. If you have ever rebuilt a tilt cylinder with a kit from a parts store and had it leak within a month, it is because the kit did not match the original seal profile. This catalog gives you the factory part numbers for the seal kit and each individual component. You can order exactly what the loader left the factory with. Also includes auxiliary hydraulics, control valve, bucket positioning valve, and front auxiliary valve.

3 Sections You Cannot Afford to Overlook

First, the hydrostatic system (pages 84-117) — hydrostatic pump, motor, gear pump, hand controls, filter. One wrong pump part can kill your wallet. Second, the electrical system (pages 118-145) — cab electrical, engine electrical, controls, alternator, starter. Parts like solenoids, sensors, and harnesses are listed with their exact connectors. Third, the power unit (pages 146-193) — cooling system, engine and attaching parts, cylinder head, camshaft, piston, crankshaft, fuel injection system. If you are ordering a head gasket or injector nozzle, you want the page 188-191 fuel injection numbers. These sections are where aftermarket catalogs make the most mistakes.

What Makes the Bobcat 853 Parts Catalog Different from Aftermarket?

Aftermarket parts catalogs are often compiled from multiple sources, scanned poorly, or missing the alphabetical index and numerical index that this document has. The alphabetical index on page 2 lists every component from ADHESIVE to VALVE STEM with page references. The numerical index on pages 349-355 lets you start with a part number and find where it is used. OEM documentation, like this one, comes from Bobcat itself. Automotive Industry Overview standards apply — the diagrams are drawn to match the actual production parts. You will not see generic “hydraulic cylinder” illustrations; you will see the exact tilt cylinder with the correct port angles and mounting brackets.

One more thing: the 316 pages are full of exploded views with part numbers in callouts. No guesswork.

Using the Numerical Index for Fast Part Lookups

If you have a part number from an existing component, flip to the numerical index starting on page 349. It lists every part number used in the catalog and tells you which page it appears on. This saves hours of leafing through sections. I keep a copy of the numerical index taped to my toolbox for fast reference. The alphabetical index works the same way — look up “BRAKE” and it points you to page B16 (which correlates to the disc brake section). Match the page number from the index to the actual page, and you have your diagram.

Frequently Asked Questions

Does this manual cover the hydrostatic system?

Yes, pages 84-117 cover hydrostatic circuitry, hand controls, motor, pump, gear pump, and oil filter.

What is the publication year of this Bobcat 853 Parts Catalog?

The publication year is not specified in the metadata (N/A). However, the manual covers serial numbers 5084 11001 & Above and 5097 11001 & Above, which indicates a mid-to-late 1990s production range. Since this is an original OEM document, not a reprint, the part numbers remain valid for those serial number ranges. Always verify your loader’s serial number before ordering. If your machine falls outside those ranges, you may need a different edition of the catalog. The 316 pages contain all sections listed in the table of contents, and the diagrams reflect the parts as originally manufactured. No aftermarket consolidation.

Does this parts catalog include wiring diagrams?

No, this is a parts catalog, not a service manual. The electrical section (pages 118-145) lists components like alternators, starters, sensors, and harnesses with part numbers and exploded views. It does not contain wiring schematics or troubleshooting procedures. For wiring diagrams, you need the Bobcat 853 Service Manual.

Can I use this catalog to order parts directly from a Bobcat dealer?

Yes. Dealers use the same part numbers. Provide them with the part number from this catalog, and they can verify fitment for your serial number. This eliminates the back-and-forth of “Is this the right part?”

Stop chasing part numbers across forums and aftermarket databases. Access the Factory Manual — the Bobcat 853 Parts Catalog — and get the exact information you need for your next rebuild.
