This Mack E-Tech engine manual goes well beyond a basic overview. It opens with a full description of the E-Tech engine design, explaining how the electronic unit pump (EUP) fuel injection system, V-MAC III electronic control system, poly-V belt drive and J-Tech engine brake differ from the earlier E7 engine. The troubleshooting chapter walks through engine symptom diagnosis with detailed charts covering engine will not crank, engine cranks but will not start, misfires, low power, excessive smoke, overheating, low oil pressure, fuel in lube oil and more. The repair instructions section provides complete bench procedures for the cylinder block, crankshaft, camshaft, auxiliary shaft, connecting rods, pistons, cylinder head, oil pump, oil cooler and water pump.

What This Manual Covers In Depth

For technicians working on the E-Tech engine, the manual documents the complete overhaul process from removal through disassembly, component reconditioning and reassembly. The cylinder block reconditioning chapter covers cylinder sleeve removal and installation, counterbore cutting with the PT2210 tool, camshaft bushing replacement, auxiliary shaft bushing replacement, cup plug and pipe plug replacement, H-ring replacement and cylinder block dowel pin replacement. The crankshaft and flywheel chapter covers inspection, dowel pin replacement, gear replacement, wear ring installation and flywheel resurfacing. The cylinder head overhaul chapter covers valve removal, valve guide replacement, valve seat insert replacement, fire ring groove cutting, injection nozzle holder insert replacement, valve yoke guide pin replacement and valve spring inspection.

The fuel system coverage is extensive, with electronic unit pump inspection, plunger spring and seat installation, fuel injector nozzle cleaning, EUP calibration and high-pressure fuel line procedures. The lubrication system bench procedures cover oil pump reconditioning with end clearance, side clearance and backlash checks, plus oil cooler reconditioning for both the removable bundle-type and plate-type coolers. The cooling system chapter covers water pump reconditioning, thermostat removal and installation, coolant manifold removal and installation, and oil cooler-to-water pump inlet line procedures.

Engine setup and adjustments are covered in detail, including valve yoke adjustment, inlet and exhaust valve lash settings, engine brake slave piston adjustment, engine speed and position sensor installation with shim selection charts, and electronic unit pump calibration. The specifications section provides mechanical specifications for every EM7 and E7 E-Tech engine rating, weights and dimensions, component features and materials, fits and limits tables, critical fastener torque specifications, hose clamp torques, pipe plug torques, engine-mounted sensor torques and non-critical fastener torque tables by property class.

Why This Manual Matters

Correct service information is critical on the E-Tech engine because of its electronic unit pump fuel system, V-MAC III controls and J-Tech engine brake. Using incorrect torque values, valve lash settings or EUP calibration procedures can lead to poor performance, excessive smoke, engine damage or brake malfunction. This Mack E-Tech workshop manual gives you the exact specifications and step-by-step procedures the engine requires. Torque values are provided in both English and metric units throughout the text, eliminating the need to convert or reference a separate chart.

The manual covers both early-production engines with the right-side mounted EECU and cooling plate, and current-production engines with the left-side mounted EECU on the one-piece air inlet manifold. It also covers the Centri-Max and Centri-Max PLUS oil filter arrangements, the plate-type and removable bundle-type oil coolers, and the pin-type and pinless valve yokes. This makes it suitable for servicing E-Tech engines across the production run, including the left-side redesign.

Who This Manual Is For

This E-Tech diesel engine repair manual is written for professional diesel technicians, fleet maintenance shops, engine rebuilders and serious owner-operators who need factory-level service information. It assumes access to standard shop tools plus the special tools listed in the back of the book, including the engine stand, adapter plate, camshaft bushing tools, cylinder liner puller, valve spring compressors, injection nozzle puller, and V-MAC III diagnostic tools. The troubleshooting charts are designed to help isolate problems systematically before disassembly, saving time and unnecessary parts replacement.

The manual also includes V-MAC III diagnostics information, referring to the separate V-MAC III service manual for blink code details, and covers the chassis-mounted charge air cooling (CMCAC) system with pressure and restriction tests. Engine brake troubleshooting is covered for both the hydraulic/mechanical and electrical sides, including solenoid specifications, oil pressure requirements, slave piston clearance settings and control valve inspection.
