New Holland B110, B115 Repair Manual

If you’ve ever chased a backhoe hydraulic leak using a third-party schematic that was off by three ports, you know the headache. I’ve been there. A shop in San Antonio, 105°F in the bay, a B115 with a slow bucket curl, and a parts-store manual that told me the charge pressure was 150 psi when it was actually 220. That mistake cost me a pump and half a day. This is why I only trust factory documents. The New Holland B110, B115 Repair Manual from AutoRepairManuals is the real deal – 993 pages, printed by New Holland themselves, and scanned clean enough to read torque tables without a magnifying glass.

This is the same manual that CNH Italia sent to dealer techs. It covers the B110 and B115 loader backhoe models in two volumes: the loader backhoe service manual (print number 87643846) and the engine service manual (print number 87643867). You get both in a single PDF. No guesswork, no aftermarket paraphrasing. Just factory procedure.

993 Pages of Factory Specs

Volume one runs through the loader backhoe structure – hydraulics, transmission, steering, brakes, electrical, and frame. Volume two is the engine: diesel fuel system, cooling, lubrication, and overhaul specs. Page 2 of the manual tells you exactly that: “The complete Service Manual consists of two volumes: B110 – B115 Service Manual ‘LOADER BACKHOE’ and B110 – B115 Service Manual ‘Engine’.” You get the full 993 pages, not a condensed rewrite. Need the main relief pressure for the backhoe circuit? It’s in the hydraulic section with a table that gives you bar and psi. No conversion math required.

Two-Volume Breakdown: Loader Backhoe and Engine

The first volume (loader backhoe) is the thicker one. It covers the machine itself – the backhoe attachment, the loader arms, the four-wheel-drive transfer case, and the cab electrical. The second volume is all engine: the FPT diesel that came in these machines, injection timing, valve clearances, and the turbocharger if equipped. Both manuals start with safety warnings that are worth reading. The manual says right on page 3: “Never attempt to clean, lubricate or adjust a machine while it is in motion.” That’s not a suggestion – it’s the reason most accidents happen. I’ve seen a tech lose a finger because he reached into a fan shroud with the engine running. This manual drills that into your head.

Safety Warnings You Cannot Ignore

Page 3 is blunt: “Before carrying out any maintenance operation, adjustment and or repair on machines equipped with attachments, controlled hydraulically or mechanically, make sure that the attachment is lowered and safely set on the ground.” If you need to raise a backhoe to get to a hose, the manual tells you exactly what supports to use – not just “use jack stands.” It specifies steel blocking, not hydraulic cylinders. That kind of detail separates a factory manual from a generic one. You want a safe shop? Use the source documentation.

What Torque Values Are Listed?

The engine volume has a full torque specification table for every threaded fastener on the diesel – cylinder head bolts, main bearing cap bolts, connecting rod nuts. The loader backhoe volume gives you torque for the pivot pins, wheel lug nuts, and hydraulic fittings. All in imperial units: foot-pounds and inch-pounds. No metric confusion. For instance, the rear axle hub nut on the B115 is 350 ft-lb. That’s not in the aftermarket manual I threw out last month. Only this OEM PDF has it.

Do I Need the Parts Catalog Too?

This repair manual covers service procedures, not part numbers. For ordering the exact bearing or seal, you want the official parts catalog. Check the New Holland B110 Parts Catalog – Section: Transmissiongearing Speed Gear for transmission internals. The New Holland B110 2007 Parts Catalog covers the undercarriage and engine components. And the New Holland B110, B115 2007 Operators Manual – OEM Specs gives you the daily operation and fluid capacities. Three documents, one stack. You get the repair manual here, the others for reference.

External resources? If you’re new to Manual Transmission rebuilds, the manual assumes you know the basics. For the theory behind synchronizer operation, check Manual Transmission fundamentals on Wikipedia. But for the actual step-by-step disassembly of the B115 transmission, stick with page 74 of this manual.

Who should buy this? DIY farmers who fix their own backhoes and don’t want to tow it to a dealer for a snapped tie rod. Farm shop managers who need a reference for the younger techs. Anyone who’s been burned by a $30 PDF that promised “complete” instructions but skipped the hydraulic pump shim procedure. This manual doesn’t skip anything.

One final note: the OCR on this PDF is solid. You can search for “bucket cylinder removal” and land on the exact page. No reprint, no missing pages. You get the same manual a New Holland dealer used in 2005 for a B110 that came in with a broken backhoe swing cylinder. I know because I’ve used it.

Does this manual cover the B115 with cab and air conditioning?

Yes. The cab electrical and HVAC are in the loader backhoe volume.

What about the engine – is the overhaul section complete with ring gaps and bearing clearances?

The engine volume gives you the full overhaul data: piston ring end gap (0.012-0.020 in for the top ring), main bearing oil clearance (0.0015-0.0035 in), valve seat angle (45°), and camshaft end play. It also includes the fuel injection pump timing procedure – you need a dial indicator and a TDC pin. The manual lists the New Holland special tool numbers for each operation. No fudge factors, no “approximately.” You get the factory standard.

You don’t need to guess, you need the factory book. Access the Factory Manual now and get your B110 or B115 back to work with the right specs.
