Read as a whole, the groups in this TAD diesel engine workshop manual build a continuous repair path: drain and expose the engine, mount it to the fixture, strip it down, measure and inspect, then rebuild it with the correct torques, gear lash values, valve clearances and injector preloads. Supporting chapters on specifications, special tools, safety and troubleshooting make sure every job starts from a known reference point rather than a guess.

What This Volvo Penta TAD Diesel Engine Repair Manual Covers

Because Groups 21 through 26 cover the engine, lubrication, fuel, air and cooling systems in full, the same document supports everything from a valve adjustment on a running TAD1360VE through to a complete bottom-end overhaul on a TAD1375VE. The main areas covered include:

• Complete engine removal and reassembly for the TAD13xx range — draining, exposing, fitting the fixture, disassembly and assembly with tightening sequences and angle-tightening stages.
• Cylinder head work — removal, cleaning, valve grinding, valve seat replacement, valve guide inspection and replacement, camshaft removal and installation.
• Cylinder liner, piston and connecting rod service — liner height measurement, O-ring installation, piston ring fitting, big-end bearing replacement, connecting rod checks.
• Valve mechanism adjustment for the standard mechanism, the VCB (Volvo Compression Brake) mechanism and the IEGR (Internal Exhaust Gas Recirculation) mechanism, with camshaft timing marks, valve clearances and unit injector preload.
• Timing gears and shafts — gear lash measurement and adjustment, camshaft wear check, flywheel indication, ring gear replacement.
• Crank mechanism — crankshaft removal and installation, main bearing and big-end bearing replacement with the crankshaft in place, crankshaft inspection, front and rear seal replacement.
• Lubrication system — oil pump change, oil filter bracket, oil cooler, safety valve, bypass valve and oil pressure sensor check.
• Fuel system — fuel feed pressure check, fuel filter housing, fuel feed pump, unit injector replacement, copper sleeve replacement, ECM control unit and data set handling.
• Inlet and exhaust system — intake manifold, exhaust manifold, turbocharger inspection and replacement, air throttle, EGR control valve, EGR mixing chamber, charge air pipe leak check.
• Emission after-treatment (AdBlue/DEF) — tank change and cleaning, pump filter, dosing unit, pump unit, temperature sensor, solenoid valve and combined tank unit service.
• Cooling system — draining and cleaning, coolant pump, thermostat, drive belts, belt tensioner, coolant filter and fan.

Torque Values, Clearances and Service Data Built Into the Procedure

Unlike a generic engine guide, this TAD engine repair manual places the numbers directly inside the job description. Cylinder head bolts are tightened in a numbered sequence through three stages including two angle-tightening steps. Main bearing caps use a two-stage torque plus 120° angle. Big-end caps use 20 Nm, 60 Nm and then 90°. Frame reinforcement bolts must be renewed and tightened in a specific 1-24 order to 45 Nm plus 60°. Timing gear plate bolts torque to 28 Nm in sequence. Flywheel bolts torque to 60 Nm plus 120°. Camshaft caps, rocker arm shaft, valve cover, intake and exhaust manifolds, fuel line brackets and unit injector yokes all have their own staged values documented in the manual’s tightening-torque chapter.

Specification chapters add the wider reference data a workshop needs: general tightening torques by bolt size, cylinder liner height above the block plane, valve head stand-out, valve seat and guide dimensions, crankshaft journal diameters including undersize options, main bearing and connecting rod shell thicknesses, crankshaft end float limits, big-end radial clearance limits, camshaft bearing journal tolerances and cam profile wear limits.

Engine Specifications Relevant to the TAD13xx Family

The manual’s engine specification section lists the common TAD13xx architecture: 6 cylinders, 131 mm cylinder bore, 158 mm stroke, 12.78-litre displacement, compression ratio 18.1:1 on most variants and 17.8:1 on the TAD1351-1353VE, TAD1360-1365VE and TAD1371-1375VE engines, injection sequence 1-5-3-6-2-4, low idle 900 rpm and high idle 1800 rpm. Dry engine weight is 1295 kg, wet weight 1325 kg, with generator-set versions heavier. Oil capacity is 36 litres on the plastic sump and 52 litres on the aluminium sump, coolant capacity is 44 litres (58 litres with the optional heavy-duty cooler).

Special Tools and Safe Working Method

Volvo Penta identifies the special tools required for particular procedures — pullers, lifting tools, dial indicators, hydraulic cylinders, drift and alignment tooling — so that jobs such as camshaft bearing replacement, valve guide replacement, crankshaft seal replacement and unit injector sleeve replacement can be carried out safely. The workshop manual also flags the fluorocarbon rubber seal handling warning, the correct RTV and anaerobic sealant use, and the cleanliness requirements around fuel and lubrication systems that will shorten an engine’s life if ignored.

Who This Workshop Manual Is For

This Volvo Penta TAD diesel engine workshop manual suits independent workshops, fleet maintenance engineers, marine and industrial engine technicians and owners who service their own TAD engine. It assumes the reader has a basic mechanical knowledge and access to normal workshop equipment; special tools are called out where they are needed and alternatives are noted where Volvo Penta has supplied them.
