Bobcat 5311, 5312 2005 Parts Catalog – OEM Factory Specs for Your Compact Loader

If you’ve ever ordered a part for your Bobcat 5311 or 5312 and got the wrong seal, bushing, or hydraulic line because the aftermarket listing was vague, you know the waste of time and money. This Bobcat 5311, 5312 2005 Parts Catalog is the document that kills that guesswork. It’s the same 400-page book Bobcat dealers pull parts from. It includes the factory interlock control system (BICS) schematics and all serial number breaks. I’m Mike Callahan – I’ve torqued more bolts than most of you have turned wrenches. When I need a part number for a machine that’s down, I don’t reach for a scanned reprint from some third-party site. I go to the original OEM print. This is that print.

Engine and Related Components – Page-by-Page Breakdown

The catalog starts with the engine assembly, covering cylinder block, head, oil pan, and all fastener groups. Every illustration is exploded – you see exactly how parts stack together. Need the part number for a fuel injection pump? It’s in the fuel system section, grouped with lines and filters. The book lists each part with its quantity, description, and interchange notes. I’ve seen techs waste an hour cross-referencing aftermarket numbers. This book gives you the OEM number on the first look. Part numbers are printed clearly, not blurred like in photocopied manuals.

Does This Parts Catalog Include Torque Specs?

No. This is a parts catalog, not a service manual. It tells you the part number, not how tight to turn it. If you need torque values, you need the corresponding Bobcat service manual for the 5311 and 5312. That said, the parts catalog does list bolt grades and thread sizes in the fastener groups, which is a lot more than you get from a generic parts list. For the BICS hardware, the catalog references special washers and bolts that are easy to overlook. I keep both books on the bench. The parts catalog is for ordering; the service manual is for wrenching.

3 Reasons to Trust the Factory Book Over Aftermarket Reprints

First, the OEM book has the exact serial number breaks: S/N 5311 11001 & Above, S/N 5312 11001 & Above. Aftermarket reprints often lump all serial numbers together, and you end up ordering the wrong hydraulic pump. Second, the paper quality and binding – this is a 2005 original print with crisp illustrations. Reprints lose detail in the shading, which matters when you’re trying to tell a seal from a spacer. Third, the parts catalog includes the Bobcat Interlock Control System (BICS) specific hardware that aftermarket listings frequently skip. I’ve had to eat the cost of a return because an online parts lookup gave me a component that didn’t fit the BICS-equipped machine. Save yourself that hassle.

Hydraulic System: Lines, Fittings, and Pump Parts

Hydraulic system is where most breakdowns happen. The catalog breaks it into three subsections: pump, control valve, and cylinders. Each hose assembly is shown with the correct fitting orientation – something aftermarket catalogs often get wrong. The drive system section covers the chain case, axle housings, and final drives. If you’re rebuilding a final drive, the catalog lists each bearing and seal with the factory number. No guesswork on which bearing race goes where. That’s worth the price of the book right there.

Understand the BICS Interlock Before You Buy Electrical Parts

The BICS system locks out hydraulics and drive unless the operator is seated and the seat bar is down. The parts catalog dedicates several pages to the switches, wiring harnesses, and the interlock module. One common mistake: ordering a generic start switch for a BICS-equipped 5312. The factory switch has an extra terminal for the interlock logic. The catalog shows the exact Bobcat part number. Same for the seat switch – the housing is specific to Bobcat. You can’t get that from an aftermarket parts house. The catalog also includes the harness routing diagram, which is printed alongside the electrical component list, page 2.

FAQ

Is this the same manual that Bobcat dealers use?

Yes. It’s the same document dealers pull parts from.

How do I find a specific part number if I don’t know the old number?

Start with the illustrations. The catalog is organized by major systems – engine, hydraulic, drive, electrical. Flip to the section that matches the part you see on the machine. Each exploded view has callout numbers that correspond to the part list. If you can identify the system (e.g., the left hydraulic cylinder), scan the cylinder subsection until you find the illustration that matches. Write down the callout number, then go to the part list for that page. The list gives the Bobcat part number, description, and quantity. If you still can’t find it, check the index at the back – it lists every part number alphabetically and numerically. This is how I train my junior techs to use a parts catalog, and it saves hours of scrolling through online databases.

If your Bobcat 5311 or 5312 is down and you need to order parts with certainty, stop guessing with aftermarket listings. Access the Factory Manual and start ordering the exact components the machine was built with.
