Case 850D, 855D 1995 Operators Manual

You bought a used Case 850D or 855D crawler. Maybe you got it cheap because the previous owner had no idea how to run it right. Or you’re a shop that needs to train new operators without burning up a torque converter. The missing piece is the Case 850D, 855D 1995 Operators Manual – the factory document, not a third-party reprint that leaves out half the safety decals. This is 182 pages of original Case content from 1995. Page 2 alone tells you that if you loan or rent this machine, the operator must read this manual. That’s a liability bullet you can avoid.

Safety First: Why Page 2 Matters

Page 2 has the ATTENTION symbol that says your safety is involved. The manual doesn’t let you skip this – it tells you to clear the area of other persons before starting the Engine. If you’ve ever seen a dozer run over a helper because the operator didn’t check the surroundings, you know why this is stamped in bold. The Safety section (starting page 8) covers decals, personal protection, backhoe operation, parking the machine, and maintenance. Page 22 has the parking procedure. I see too many guys hop off a crawler without setting the parking brake or lowering the blade. This manual nails that into your head.

Controls and Instruments: Know Every Lever Before You Touch It

Controls and Instruments chapter starts at page 28. You get the instrument panel layout, foot pedals, transmission controls, neutral lock and starter button, master disconnect switch, parking brake, loader lift arm and bucket control, 4-in-1 bucket and ripper controls, dozer controls, winch control, backhoe controls (foot swing and hand swing), Extendahoe controls, suspension seat, seat belts, and cab controls. Page 31 covers transmission controls – the exact pattern for forward/reverse and speed ranges. If you skip reading that section, you’ll be hunting for the wrong lever when you need to steer the crawler on a slope. That’s how things get bent.

Engine Operation and Cold-Weather Starting – Do It Right

Operating Instructions start on page 48 with Engine Operation. Walk-around inspection (page 48), starting procedure (page 49), operating turbocharged engine (page 50), engine speed, and stopping sequence. Page 52 explains methods to help start the engine during cold weather. If you’ve ever been on a jobsite at 20°F with a dead battery and no ether can, you’ll read that section twice. The manual doesn’t assume you know the limits – it tells you when to use the cold-weather starting aids and when not to. Also covers operating in hot temperatures (page 64) and the specific crawler steering technique on page 58. This is the difference between a machine that lasts 10,000 hours and one that blows a final drive because the operator rode the clutch.

3 Maintenance Schedules You Can’t Skip

Maintenance and Lubrication chapter (page 93) is where most damage gets prevented. Page 95 has the Fluids and Lubricants Chart – oil viscosities, hydraulic fluid specs, coolant type. If you throw in the wrong engine oil because you guessed, you’ll pay for a rebuild. Page 98 shows the Maintenance Schedule – what to do at 10, 50, 250, 500, 1000 hours. Run-in period (page 97) is critical for new or rebuilt engines. Grease fittings (page 101) – the manual lists every zerk location. Air cleaner (page 106), engine lubrication system (page 109), cooling system (page 111), fuel system (page 113), hydraulic system (page 117), transmission and torque converter (page 119), final drives (page 122), batteries (page 123), track system (page 124), winch (page 127), brake system (page 136), loader return-to-dig adjustment (page 142). That’s 49 pages of detailed procedures – not a highlight reel.

Specifications and Serial Numbers – No Guessing

Specifications start on page 154. Engine power ratings, travel speeds, capacities, dimensions. Diesel fuel specifications (page 168). Product identification and serial numbers (page 169) – you need those numbers to order the correct replacement parts. This Operators Manual also includes the Index (page 172) and After Delivery Check (page 175). If you want to dig into related Case machines, check out the Case SL1-b, SL2 1995 Operators Manual – Factory Specs or the Case SV212, SV216, SV208, SV210, SV223 Operators Manual – 214 Pages. For a different model, the Case SV212 SV216 1994 Operators Manual – Factory Specs might be what you need. For general knowledge on how a Manual Transmission works in a crawler, that’s separate – but this manual’s transmission controls section (page 31) is specific to the Case powershift. And if you’re also working on a vehicle with a Manual Transmission, don’t confuse the two – the principles of lubrication apply, but the engagement procedures are completely different.

Does this Operators Manual include repair procedures?

No. This manual covers operation, maintenance, and safety. For repairs, get the Service Manual.

What is the difference between an Operators Manual and a Service Manual?

An Operators Manual tells you how to use the machine safely, perform daily checks, and follow maintenance schedules. A Service Manual gives you step-by-step disassembly, overhaul specs, and troubleshooting. Both are needed if you maintain your own equipment. This one is the Operators Manual.

How is this manual different from a photocopy?

Photocopies lose contrast on safety decals and specs. This is a digital scan of the original 1995 print, clean and legible. You can zoom in on the fluid chart without guessing.

Can I use this manual for a different model year?

The 1995 Operators Manual covers 850D and 855D crawlers built for that year and likely adjacent years. However, Case issued updates. If your machine has a different serial number range or modifications, cross-check with your dealer. The manual includes product identification and serial number locations on page 169. Production changes after 1995 may affect controls or maintenance intervals, so always verify your specific machine. For other year 850/855 series, look for the matching year binder.

If you’re running a Case 850D or 855D – whether in a rental fleet, a construction crew, or your own shop – this Operators Manual keeps everyone on the same page. The factory procedures, torque values you can trust, and safety guidelines you can enforce. Access the Factory Manual and put it in the cab. Your techs will thank you, and so will the machine.
