Description

Volvo Penta TAD540-873VE Workshop Manual – Groups 21-26

This Volvo Penta TAD540-873VE Workshop Manual is the Groups 21-26 service reference for the TAD540, TAD550, TAD570, TAD840, TAD850 and TAD870 VE-series industrial diesel engines. Issued by AB Volvo Penta as document number 47705010 in edition 03-2018, it delivers the technical data, component descriptions, and step-by-step maintenance and repair instructions that a workshop needs to disassemble, inspect, reassemble and adjust these engines correctly.

The manual is written for Volvo Penta workshops and qualified personnel. It assumes the reader has a fundamental knowledge of the product and can carry out mechanical and electrical work to trade standard. Every procedure is written around the use of Volvo Penta Special Tools where such tools exist, and the manual repeatedly reminds the technician to follow the stated wear tolerances, torque values and adjustment values.

Chapters Covered

The Volvo Penta TAD540-873VE Workshop Manual is organised by group number, which is the standard Volvo Penta way of splitting an engine into serviceable systems. The contents break down as follows:

• General Information (00-0 General)
• Specifications (03-0 General Specifications, 03-2 Specifications, Engine)
• Safety and Other Instructions (05-1 Safety Instructions)
• Special tools (08-2 Special Service Tools)
• Engine (21-0 Engine Complete, General; 21-1 Cylinder Head; 21-4 Valve Mechanism; 21-5 Timing Gears and Shaft; 21-6 Crank Mechanism)
• Lubricating and Oil System (22-1 Oil pump and Line; 22-2 Oil filter; 22-3 Oil cooler)
• Fuel System (23-0 Fuel System, General; 23-3 Fuel Feed Pump and Filter; 23-7 Injectors and Delivery Pipes; 23-9 Miscellaneous)
• Inlet and Exhaust System (25-1 Inlet and Exhaust Manifolds; 25-4 Emission Control, Catalytic Converter; 25-5 Turbo and supercharger; 25-6 Air Cleaner, Throttle Housing; 25-8 Emission After-Treatment)
• Cooling System (26-0 Cooling System, General; 26-1 Radiator, Heat Exchanger; 26-2 Coolant Pump, Thermostat; 26-3 Fan, Fan Shroud)
• Alternator, Charge Regulator (32-1 Alternator)
• Starting System (33-1 Starter Motor)

Taken as a whole, the document gives a technician the complete workflow for a top-end or full engine overhaul on these VE-series diesels: removing and refitting the fixture, disassembling and assembling the engine, changing the cylinder head, setting valve clearance and adjusting the exhaust brake, timing the gear train, pulling and refitting the crankshaft and pistons, replacing the front and rear crankshaft seals, servicing the lubrication circuit, working on the common-rail fuel system including high-pressure pump and injectors, replacing the turbo and its oil and coolant lines, servicing the EGR cooler and the exhaust after-treatment system, and repairing the cooling system, alternator and starter motor. It also contains the tightening torque tables and clearance values needed to put every one of those systems back together to specification.

What Is Inside

The manual is not simply a list of repair jobs. Each group opens with the relevant specifications and then walks through the work as a sequence of operations, with the same structure used across groups: removal, inspection, installation, adjustment. The result is a consistent reference that can be used in a workshop fixture or in situ on the machine.

Engine (Group 21) is the largest section. It covers fitting the engine to the fixture, engine disassembly and assembly, cylinder liner installation and measurement, crankshaft removal and installation, main bearing cap tightening in sequence, thrust washer class checks, piston ring installation, connecting rod installation and end float measurement, cylinder head removal and refitting, camshaft change and wear check, valve adjustment (including exhaust brake adjustment), valve removal and installation, and valve guide inspection.

Lubrication (Group 22) covers the oil pump and lines, the oil filter and filter housing, and the oil cooler including O-ring replacement and torque values.

Fuel (Group 23) covers bleeding the fuel system, the pre-filter and main filter, the filter housing, the high-pressure pump with its gear wheel and MPROP valve, the injectors and delivery pipes, the common rail, and the pressure limiting valve.

Inlet and exhaust (Group 25) covers the intake and exhaust manifolds, the e-EGR cooler for both the 5 L and 7.7 L engines, the turbocharger inspection and change, the air throttle, and the exhaust after-treatment system including AdBlue/DEF tank, pump, dosing unit, hoses, filters and sensors.

Cooling (Group 26) covers coolant level checks and refill, coolant change, radiator assembly, coolant pump and thermostat, drive belt and belt guards, and the viscous fan.

The final two groups, 32-1 and 33-1, cover the alternator (including pulley replacement) and the starter motor.

Why This Manual Matters

These are common-rail, turbocharged, emissions-controlled industrial diesel engines. The tolerances are tight, the torque values are specific, and the sequence in which fasteners are tightened matters. On a Volvo Penta TAD540-873VE engine, using the wrong cylinder head tightening sequence, the wrong angle-tightening figure, or the wrong injector delivery pipe torque can lead to gasket failure, fuel leaks, or damage to the high-pressure fuel circuit. The workshop manual is what keeps that from happening, because it gives the exact figures and the exact order for each operation.

The manual also covers work where cleanliness and correct tooling are decisive: injector removal and installation, high-pressure pump removal, common rail service, and the fuel system bleeding procedure. Each of these is written out as a step sequence with the safety plugs, protective caps, new O-rings and torque values called out as they are needed.

Special tools are referenced by part number throughout, including lifting tools, drift tools, press tools, guide pins, the extractor for crankshaft seals, the pressure testing kit for the cooling system, the EGR cooler connection washers, the rotation tool for valve adjustment, and the timing tool for the exhaust brake. Knowing which tool is required for a job is part of doing the job correctly.

Who This Manual Is For

This Volvo Penta TAD540-873VE Workshop Manual is intended for Volvo Penta workshops, qualified mechanics, fleet maintenance technicians, and anyone carrying out major service or repair work on a TAD540, TAD550, TAD570, TAD840, TAD850 or TAD870 VE-series engine. It is also useful for owners and operators who want to understand what a repair involves before authorising it, or who do their own maintenance to a professional standard.

Because the manual covers Groups 21-26 plus the alternator and starter motor, it is particularly useful for a full engine overhaul or a major top-end repair, where the work crosses from the cylinder head into the fuel, cooling and after-treatment systems.

What You Can Do With It

With this manual in hand, a technician can carry out a complete engine disassembly and reassembly with the correct torque and angle figures, change a cylinder head and set valve clearances, adjust the exhaust brake, remove and refit the camshaft and timing gears with the correct gear alignment marks, replace the front and rear crankshaft seals, remove and install pistons and connecting rods, service or replace the oil pump, oil filter and oil cooler, work on the common-rail fuel system including the high-pressure pump, injectors and delivery pipes, replace the turbocharger and its oil and coolant lines, service the e-EGR cooler, replace AdBlue/DEF system components, replace the coolant pump and thermostat, replace the radiator, drive belt and viscous fan, and replace the alternator and starter motor.

In short, it covers the work that keeps these engines running and the work that brings them back when something fails.
