Ford 2701B, 2703E, 2704E, 2701C, 2703C 1979 Service Manual

You’ve got a Ford industrial diesel on the stand—maybe a 2701B four-cylinder or a 2703E six-cylinder—and you’re staring at a pile of bolts, a bent pushrod, and a set of aftermarket instructions that tell you to “tighten to spec” without showing you the goddamn spec. That’s the exact moment you need this book. Not a reprint, not a scanned copy with missing pages. This is the original 1979 Ford 2701B, 2703E, 2704E, 2701C, 2703C 1979 Service Manual from Ford Motor Company Ltd., 358 pages of factory procedure that tells you which way the liners go in and what torque to apply on the cylinder head without guessing.

Engine Overhaul: Section 1 Coverage

Section 1 runs from the general description straight through dismantle and reassembly. It covers the cylinder head, valves, springs, rocker shaft assembly, and the critical replacement of Cromard liners. If you’ve never pulled a liner from a 2704E, the manual walks you through the tooling required and the press fit specs. Page 19 has the complete specifications table—torque values for main bearing caps, connecting rod bolts, and the head bolts. Don’t trust a third-party chart for that. Use the factory data.

Cooling and Lubrication: Section 2

Section 2 splits into the lubrication system and the cooling system. Oil pump clearances, cooler bypass valve settings, thermostat ratings—all there. The manual tells you to check the oil pressure relief valve spring free length before reassembly. Overlook that and you’ll starve the turbo bearings on a 2704ET. The cooling section includes water pump disassembly and radiator cap pressure test specs. If you’re swapping a water pump on a 2701C, verify the impeller clearance with a feeler gauge; the book gives the number.

Fuel Systems Including Turbocharger: Section 3

This section covers injection pumps, injectors, governor adjustments, and the turbocharger assembly. For the 2703E and 2704ET, the manual details the boost compensator calibration and wastegate setting. You’ll find the injection timing marks for both rotary and inline pumps. Don’t try to set the timing by ear—this book shows the static timing method using a dial gauge. The turbocharger section includes oil feed and drain line torque and the correct tightening sequence for the turbine housing bolts.

Electrical System Diagnostics: Section 4

Section 4 covers the starter motor, alternator, wiring diagrams, and glow plug system. For the 2704E with the later pre-engaged starter, the manual gives the pull-in and hold-in winding resistance values. The glow plug circuit includes the timer relay test procedure. If you’re chasing a no-crank on a 2701B, the wiring diagrams show the interlock circuit for the safety start switch. Don’t use a generic diagram—the pin assignments differ between the 2701C and 2703C chassis.

358 Pages of Factory Data

That’s 358 pages total, divided into seven sections: engine overhaul, lubrication and cooling, fuel systems (including turbo), electrical, additional equipment, service tools, and combine harvester. The combine harvester section (Section 7) adapts these engines into self-propelled harvesters, with specific PTO and hydraulic pump drive specs. The manual includes torque values for all major fasteners, clearance limits for bearings and liners, and the special tools listed in Section 6. If you don’t have the factory tool for compressing valve springs on the 2704E, the manual shows you how to fabricate one from a length of tubing.

Is Aftermarket Documentation Reliable?

I’ve seen aftermarket manuals call for 85 lb-ft on Ford 2700 connecting rod bolts when the factory spec is 59 lb-ft for the initial torque plus a 60° angle. That difference snaps bolts. This manual is the original Ford publication—copyright June 1979, printed by Ford Motor Company Ltd., Brentwood, Essex. The tables and diagrams were drawn from production engine teardowns. There’s no interpretation, no condensation, no “simplified” steps. It’s the same book the dealership technicians used. For other Ford industrial models, check the Ford 2100, 2110, 3100, 4100, 4110 Service Manual – Pre-1975 or the Ford Sierra RS Cosworth 1985 Service Manual – OEM Specs. The Ford SSD-327, SSD-437, SSD-655 1979 Service Manual OEM is another factory-bound reference.

FAQ

Does this manual cover the Combine Harvester attachment?

Yes, Section 7 (page numbers for that section are not in the provided OCR, but it is listed in the Table of Contents). It includes the specific modifications for self-propelled harvester applications, such as PTO drive alignment and hydraulic pump mounting.

What torque specs are given for cylinder head bolts?

The manual lists torque values in the Specifications sub-section of Section 1, on page 19. For the 2701B four-cylinder, the cylinder head bolt torque is given in lb-ft with an additional angle tightening step. You must refer to the factory table because the sequence differs between the four- and six-cylinder engines. Using aftermarket data risks head gasket failure and coolant leaks. The entire specification table is reproduced from original Ford engineering data, not a compilation.

Stop wasting time on vague online forums and reprinted junk that blurs the numbers. This is the real document—Ford’s own 1979 service manual for the 2700 Range Engines. You get every section, every diagram, every torque value straight from the factory. No abbreviations, no missing pages. Access the Factory Manual now and torque those head bolts to the correct spec the first time.
