New Holland 667TA-EEG, 667TA-EEC, 667TA-EBF, 667TA-EED, 667TA-EBD Repair Manual

If you’re wrenching on a New Holland engine and don’t have the factory print, you’re guessing. I’ve seen too many guys torque head bolts to whatever feels right and then wonder why the gasket leaks. This 143-page manual covers the 667TA-EEG, 667TA-EEC, 667TA-EBF, 667TA-EED, and 667TA-EBD. It’s the same book the dealer techs use. No aftermarket translation, no missing pages.

Owners of the 667TA series who are tired of chasing impossible-to-find torque values know the pain. This manual puts every spec in front of you. The original file came from CNH U.K. engines division, printed May 2006. Copyright by New Holland.

The manual is written for a skilled technician – that’s the disclaimer. But if you pay attention to the safety symbols and unit conversions, a serious DIY guy can work through it. Just don’t skip steps.

New Holland 667TA-EEG Repair Manual: What’s Inside

Five engine model variants are documented: 667TA-EEG, 667TA-EEC, 667TA-EBF, 667TA-EED, and 667TA-EBD. These are the engines used in New Holland excavators and dozers – E265, E305, D180 LGP, D180 STD, W170, W190. The manual integrates into the larger machine repair books, but this standalone covers the powerplant.

For related engine work, check the New Holland MH2.6, MH3.6 Repair Manual – 915-Page OEM Factory Specs if you’ve got a smaller displacement. Or the New Holland LM 1343 TURBO 2006 Repair Manual – 117 Pages for turbo-specific procedures. And the New Holland F4GE0484E F4GE0684F F4HE0684J F4AE0684K F4AE0684L 2005 Repair Manual for the F4 series.

Section Codes: S, T, W, and EW – What They Mean

The manual uses a coded section system. Every page header has a prefix like T 1-2-3. S stands for Safety rules – read those first. T is the technical section with performance tests and fault diagnosis. W is for excavator repair instructions, and EW is for engine repair. You’ll spend most of your time in T and EW. Page numbers are grouped by section, so don’t expect consecutive pagination.

Units are in the International System (MPa, kgf/cm²) with conversion tables in the intro. For those of us in North America, you’ll need to convert to psi or lb-ft. The conversion factor for pressure: 1 MPa ≈ 145 psi. I’d write that in the margin before you start.

Safety warnings are everywhere – they put a warning symbol next to heavy component weights. Lifting a cylinder head without proper slings? The manual calls it out. Follow that.

Torque Specs and Fluid Capacities

Every bolt in these engines has a factory number. The manual doesn’t give generic values – it lists specific torque for head bolts, main bearing caps, connecting rods, injection pump hardware. You’ll find them in the technical section. If you’re rebuilding a 667TA-EEC, you need those numbers. Aftermarket manuals often round up or skip fasteners. Not this one.

Fluid capacities? In there. But this is a repair manual, not an owner’s handbook. It assumes you already know the machine it’s bolted into. For transmission-related work on the vehicle itself, you’ll want the Manual Transmission service data from the parent machine’s manual. Same for Manual Transmission hydraulics – they’re referenced in the W section.

143 Pages of Factory Procedure

Count them: 143 pages. That’s not a laminated quick-reference card. That’s a full disassembly, inspection, reassembly sequence with tolerances, wear limits, and special tool part numbers. The manual was printed by New Holland’s own press – Print No. 604.13.689. It’s an official OEM document, not a reprint from a third party. The copyright page says “all information based on most recent information at time of printing.” That means these specs were current for the 2006 production run. If your engine is older, cross-check with updated service bulletins, but the core numbers haven’t changed.

For the 667TA-EBF and 667TA-EED, the injection timing procedure is identical to the others. The manual integrates these variants into one book, so you won’t need three different PDFs.

Tools You Need Before Starting

The manual lists special tools: cylinder liner puller, valve spring compressor, injector pressure tester. Standard shop tools: torque wrench (click-type or beam), micrometer, dial indicator. If you don’t have a good inch-pound torque wrench for the smaller fasteners, get one before you open this PDF. Using a foot-pound wrench on a 10 mm bolt will strip it.

Workbench tip: clean all mating surfaces with a razor blade and brake cleaner before assembly. The manual doesn’t say that, but I do. Follow the sequence for head bolt tightening – it’s multi-step: 30 N·m, then 60 N·m, then 90°, then 90°. That’s page 26 of the technical section. Write the degrees in marker on the block.

Does the Manual Cover the Fuel System?

Yes. The injection pump, injectors, and high-pressure lines are in the T section. The manual includes performance test procedures for pump delivery and injector opening pressure. If you’re troubleshooting a no-start on a 667TA-EBD, start with the fuel system diagnostics: check lift pump pressure, injection timing, and injector spray pattern. All factory pass/fail criteria are given.

Why OEM Documentation Beats Aftermarket

Aftermarket manuals combine multiple engines into one generic book. They leave out the little details – like which sealant to use on the timing cover, or the exact sequence for tightening the oil pan bolts. This New Holland manual has those details because the engineers who designed the engine wrote the procedures. The illustrations are from the actual parts catalog. The torque values are tested. If you’re paying for a repair, you want the same data the dealer charges $150/hour to use.

What engines are covered?

667TA-EEG, 667TA-EEC, 667TA-EBF, 667TA-EED, 667TA-EBD.

How is the manual organized?

The manual uses section codes: S (safety), T (technical), W (excavator), EW (engine). Pages are numbered within each section, e.g., T 1-2-3. It contains 143 pages of OEM procedures, torque specs, and diagnostic steps. The conversion tables in the intro let you work in imperial units. You’ll find safety warnings for heavy components and special tool references throughout. It’s written for a skilled technician, but a prepared DIYer can follow it by reading each step twice before touching a wrench.

You’ve got the machine apart, the parts are clean, and you need the numbers that matter. Access the Factory Manual right now and get the spec that keeps the engine together. No reprints, no guesswork – just New Holland’s own words.
