Bobcat 853 Parts Catalog – 316 Pages of Factory Part Numbers

If you’ve ever ordered a replacement part for a Bobcat 853 only to get the wrong size, wrong thread pitch, or a seal that doesn’t fit, you know how much wasted time costs. I’ve been turning wrenches for 28 years, and I’ve seen aftermarket cross-reference charts that send you to a part that’s “close enough” but leaves you with an oil leak on a Friday afternoon. That’s why a real OEM Bobcat 853 Parts Catalog belongs on every loader owner’s shelf. Not a third-party reprint. Not a scanned copy that makes you guess at bolt lengths. This is the factory document, 316 pages of exploded diagrams and alphabetical part indices that show you exactly what goes where.

Alphabetical Index: Find Any Part in Seconds

The manual opens with a full alphabetical index mapped to specific page grids. Need a cooling fan drive? Look up “BELT, COOLING FAN DRIVE” under G14. Need the cylinder head gasket? “CYLINDER HEAD” is listed under H6. Each entry points to the exact page where the part is drawn with its reference number. No thumbing through 300 pages blind. The index covers everything from ADHESIVE to SEAT BELT, including less common items like INSECT SCREEN KIT (page M5) and EXTINGUISHER (page K1). That kind of organization saves you from pulling a part off the machine and measuring it against a catalog photo.

Cooling System: Radiator, Fan, and Drive Assembly Details

The Cooling section in this manual (pages G2 through G24) breaks down every component you need to keep an 853 from overheating. You get the radiator cap PN, the fan blades, the water pump (page H16), and the complete cooling fan drive assembly on page G24. The belt routing is shown for both the main drive and the fan drive. If you’re chasing a high-temperature issue, having the factory diagram saves you from swapping parts until you get lucky. The part numbers are the ones Bobcat stamped on the bin.

Bob-Tach and Lift Arm Breakdown

The Bob-Tach system is listed under B2 and B6 in the index. This manual dedicates multiple pages to the locking mechanism, including the rubber boots (B8) and the cylinders that control lift and tilt (pages C2 through C6). When a Bob-Tach pin seizes or a tilt cylinder leaks, you need the exact seal kit number. The exploded views show every snap ring, spacer, and O-ring in the stack. No guessing which hydraulic fitting goes where.

Engine Section: H2 to H22 – Cylinder Head, Crankshaft, Injection

From the cylinder head (H6) to the camshaft (H8), cylinder block (H10), crankshaft (H14), and injection nozzles (H20), this catalog covers the entire powertrain. The engine section includes part numbers for the oil pump (H10), water pump (H16), glow plugs (H20), and the injection pump. If you’re rebuilding a 853 engine, you can order every internal part by the factory number. The manual also covers the manifold (H4) and air cleaner (H22).

Hydraulic and Hydrostatic: Pumps, Motors, and Filters

The hydraulic system is where many aftermarket catalogs fall short. This manual includes pages for the hydrostatic pump (E8, E12), gear pump (E17, E18), and hydrostatic motor (D12, D16, E6). It also lists oil coolers (D20), filters (D18, D20, E19), and the caps for the hydraulic oil tank (D12, D16). If you need a seal kit for a motor, the exploded view on page E6 gives you the factory layout.

Why an OEM Catalog Beats Aftermarket Cross-References

Aftermarket catalogs often combine multiple model years into one generic drawing. The Bobcat 853 Parts Catalog is specific to serial numbers 5084 11001 & Above and 5097 11001 & Above. That means the part numbers match the actual production run. I’ve seen too many DIYers buy a part that “fits” from an online chart, then find out the bolt pattern is off by 2 mm. With this PDF, you read the part number off the diagram, order that number, and bolt it in. No reprints, no third-party guesswork.

Does this parts catalog include torque specifications for reassembly?

No. This is a parts catalog, not a service manual. It shows exploded views and part numbers, but does not list torque values or assembly procedures.

What is the difference between this OEM catalog and the aftermarket parts catalogs I see online?

Aftermarket catalogs often compress multiple machine variants into one drawing, leading to mismatched parts. This OEM catalog is specific to the Bobcat 853 with the exact serial number ranges listed on page 1. The index is alphabetical, so you can find, for example, the “COOLING FAN DRIVE ASSY” on page G24 without guessing. Every part number comes from Bobcat’s own engineering drawings. If you order by the number in this catalog, you get the correct part the first time.
