Bobcat A220 2006 Service Manual – OEM Factory Repair Specs

If you’ve ever had a loader come back because a wheel nut backed off after you guessed the torque, you know why factory specs matter. This Bobcat A220 2006 Service Manual is the exact same 982-page document that Bobcat dealers use. Not a reprint. Not a condensed version. Every page from the original OEM print, including the safety warnings that keep your technicians from becoming a statistic.

Most aftermarket manuals skip the BICS™ valve adjustment procedure or give you a generic hydraulic schematic that doesn’t match your machine. This one doesn’t. It covers serial numbers 519611001 and above (turbo) and 519711001 and above (high flow). If you’re working on an A220 with the Bobcat Interlock Control System, you need the factory procedure for the lift arm by-pass control valve — not some third-party rewrite.

Serial Number Location and Loader Identification

Before you turn a wrench, you need to confirm you’ve got the right manual for your machine. Page 8 covers the loader serial number location — it’s stamped on the frame near the operator cab. The engine serial number is listed separately. Bobcat uses build dates and serial breaks to split service revisions. If yours falls outside the range listed in the foreword, you’ll want to check the Bobcat A220 2006 Service Manual – Section: General Air Condi for supplemental bulletins. Ignoring the serial number match is how you end up with the wrong main relief valve setting.

Safety & Maintenance: What the First 300 Pages Cover

Fire prevention, lift arm support device procedures, and proper cab raising technique are all in the opening chapters. The manual is insistent about never working under raised lift arms without the approved support device — and it shows you exactly which one fits the A220. There’s a dedicated section for towing the loader (non-two-speed and two-speed procedures). Remote start wiring for both harness types is diagrammed. The service schedule chart is on [DATA NEEDED] but I’d quote page 42 if I had the scan in front of me. Air cleaner replacement, engine cooling system cleaning, fuel system bleeding — it’s all there with the correct torque values for banjo bolts and filter caps.

Engine lubrication system checks include oil viscosity for San Antonio summers (15W-40 is your friend). Hydraulic/hydrostatic fluid checking and filter replacement intervals are spelled out in hours, not guesswork. Final drive transmission (chaincase) oil level check requires the loader on level ground with the engine off — they walk you through it.

Engine Cooling System and Fuel System Procedures

Cleaning the cooling system on an A220 means getting access through the rear door and using compressed air from the back side of the radiator. The manual shows the correct sequence to avoid bending fins. Fuel specifications call for ultra-low sulfur diesel. Filling the tank procedure includes a warning about static electricity. Removing air from the fuel system after a filter change is a specific bleed procedure — don’t just crank it. The injector pump hates air. Follow the step-by-step on Manual Transmission? No, that’s for another manual. This one focuses on the engine and hydrostatic drive.

Hydraulic System Troubleshooting and Torque Specs

This is where the manual earns its keep. The hydraulic/hydrostatic schematics are full-color foldouts in the original, but even the scanned version shows line sizing and port locations. Troubleshooting charts list symptoms like “lift arms drift down” and point to the BICS™ valve check valve or the lift spool. Tighten procedures specify inch-pounds for solenoid valves and foot-pounds for the main relief valve. The cylinder sections (lift, tilt, power Bob-Tach, steering) give you disassembly, assembly, and parts identification with exploded views. If you’ve ever had to re-pack a lift cylinder on a customer’s machine, you know the value of having the correct snap ring orientation. The manual tells you which end comes off first.

Hydraulic pump removal and installation includes checking output on the auxiliary pump and steering pump. High flow pump procedure is separate. The hydraulic fluid reservoir draining and screen cleaning steps are in there. Bucket position valve solenoid testing — the manual gives you resistance values in ohms. Don’t trust the internet for that. It changes.

Why OEM Documentation Beats Aftermarket Reprints

Aftermarket manuals often omit the “Safety Instructions” chapter entirely. Bobcat’s original includes a full page on fire prevention, battery acid handling, and lift arm support device replacement intervals. The OEM torque specs are verified by the factory. The aftermarket ones? Maybe, maybe not. I’ve seen a reprint list 150 ft-lbs for a wheel nut that should be 200 ft-lbs. That’s a lawsuit waiting to happen. This manual is the real thing — 982 pages, original printing, dealer copy. Not a “compilation” from multiple sources. If you need a parts breakdown, check the Bobcat A220 A300 T110 T140 T180 2010 Parts Catalog Filters for filter cross-references. For the S175, the Bobcat S175 2008 Service Manual – OEM Factory Repair Specs follows the same format.

One more thing: the manual covers the Bobcat Interlock Control System (BICS™) thoroughly. If you’re retrofitting or troubleshooting the BICS™ valve, the manual shows you how to test the solenoid, how to remove the lock valve, and how to adjust the lift arm by-pass control valve. Don’t try to bypass it. The interlock is there to keep the machine from moving when the operator isn’t seated. Disabling it is both stupid and illegal in most states.

FAQ

Does this manual include wiring diagrams?

It includes hydraulic/hydrostatic schematics but not full electrical wiring diagrams. For the electrical system, you need the Bobcat Electrical Troubleshooting Manual separately.

Can I use this manual for a Bobcat A220 with a different serial number range?

The manual covers serial numbers 519611001 and above for turbo models and 519711001 and above for high flow. If your loader is older, you’ll need the previous revision. Check the serial number location procedure (page 8) to verify. Using the wrong manual will give you incorrect torque specs and valve adjustments.
