Komatsu CD110R-2 2005 Workshop Manual – Factory Specs for the SAA6D114E-2

Got a CD110R-2 on the lift with an engine that won’t hold oil pressure, or a cooling system that pegs the gauge? Before you start throwing parts at it, you need the real numbers. Not some aftermarket translation that rounded the torque values. This Komatsu CD110R-2 2005 Workshop Manual is the same 383-page document our shop used when these machines were still under warranty. It’s the exact procedure Komatsu published for serial number 1501 and up. If you’ve ever wasted a Saturday on a fuel system bleed because the factory sequence wasn’t in the manual you bought off a forum, you know why this matters.

What the “Table of Fuel, Coolant and Lubricants” Actually Tells You

Page 01 of this manual lays out the specification drawing and a table that lists every fluid the CD110R-2 needs, including the type and capacity for fuel, coolant, and lubricants. That’s not just “use 10W-30.” It gives you the exact Komatsu part numbers and the API classifications. For the cooling system, it specifies the coolant mixture ratio and the corrosion inhibitor concentration. Run the wrong coolant and you’re chasing pitted liners in 2000 hours. I’ve seen it happen. That table alone saves you from that mistake.

Cooling System Diagnostics – Why the Factory Procedure Matters

Section 10 covers the cooling system in detail – fan drive, radiator, coolant flow path. But the real meat is in Section 20: Testing and Adjusting. The manual lists the standard value table for engine parameters, including coolant temperature sensor resistance and thermostat opening temperature. Need to confirm the fan clutch engagement point? It’s in there. Too many guys guess at cooling system fixes because they don’t have the spec. This manual gives you the spec and the step-by-step to test it. Komatsu WA65-5 WA70-5 WA80-5 2005 Workshop Manual covers similar chassis if you’re working on those models too.

Valve Clearance Adjustment – The Right Way

Valve adjustment on the SAA6D114E-2 isn’t “turn the nut until it feels right.” The manual has a full procedure under “ADJUSTING VALVE CLEARANCE” in Section 20. It gives you the clearance in inches for both intake and exhaust valves, the firing order, and the rotation direction. It also tells you the torque for the lock nut and the rocker shaft bolts. Miss that spec and you’re either too tight (burns a valve) or too loose (covers the engine in clatter). You get that in the factory manual. The aftermarket PDFs I’ve seen skip the torque spec entirely – they just say “tighten securely.” That’s useless.

Troubleshooting Electrical Error Codes Like E108 and E112

Section 20’s troubleshooting chapter is where this manual earns its keep. It covers error codes in the electrical system – E108 (engine coolant overheating), E112 (short circuit in normal rotation of windshield wiper motor), E201 (travel alarm relay), and a dozen more. Each code has a troubleshooting table: what to check, what connector to probe, what resistance to expect. Page 20-203 starts the connector arrangement and pin numbers. You don’t have to trace wires blind. If you’ve dealt with the E203 swing parking brake solenoid short circuit, you know the factory diagram is the only way to find it without burning up the controller. Komatsu WH609-1E0 WH613-1E0 WH713-1E0 WH714H-1E0 WH716-1E0 Workshop Manual uses the same electrical troubleshooting structure – useful if you see those in the shop.

Testing and Adjusting Procedures – Over 30 Specific Checks

The manual doesn’t stop at theory. It walks you through testing engine speed, measuring boost pressure, adjusting fuel injection timing, bleeding air from the fuel circuit, and checking HST oil pressure. Each procedure includes the required tool list – things like a tachometer, compression gauge, or pressure test kit. For the governor motor lever stroke adjustment, it gives you the exact length and where to measure from. That level of detail is why I won’t touch a Komatsu without the factory book. Komatsu PW95R-2 Workshop Manual – 520 Pages of Factory Specs is another thick book for the wheeled version – same attention to spec.

Who Needs This 2005 Workshop Manual?

If you own a CD110R-2 and you do your own repairs, this is the difference between getting it right and buying parts twice. The home garage mechanic who wants to save the dealer labor rate – this manual gives you the factory procedure. The professional shop that sees these machines regularly – you need it to quote jobs accurately and avoid comebacks. And the fleet manager who wants to keep downtime low – put this on every tech’s tablet.

Source Authenticity – Komatsu vs. Third-Party

Every page in this PDF is scanned from the original Komatsu shop manual printed in 2005. No translation errors, no “generic” illustrations. The torque values, wiring colors, and hydraulic pressures are exactly what Komatsu’s engineers specified. Compare that to the third-party manuals that copy the table of contents but change the numbers. I’ve seen a “universal” manual recommend 80 ft-lb for a bolt that Komatsu says 45 ft-lb. That’s how you snap a fastener or cause an oil leak. Spend the money on the real thing. For more on why factory documentation beats aftermarket, read about Manual Transmission rebuilds – the same principle applies: factory specs or wasted labor.

FAQ – Two Questions I Hear in the Shop

Does this manual include the engine rebuild specs for the SAA6D114E-2?

Yes. Section 30 (Disassembly and Assembly) is listed for future issue, but Section 20 covers all testing and adjusting for the engine, including compression pressure, blow-by, and valve clearance. The engine is covered in the 114 Series Engine Shop Manual referenced on page 1.

Can I use this for serial numbers before 1501?

No. This manual is for serial number 1501 and up. Earlier machines may have different specs.

Stop pulling your hair out over missing specs. Access the Factory Manual and get the job done right.
