Every one of the 112 pages in this Perkins V8.640, TV8.640, AV8.640, ATV8.640 Shop Manual PDF (OEM 601 TPD 0983 1149) is aimed at the V8 diesel on your bench, from the base engine to the turbocharged and air-compressor variants. You get a fault finding chart, a full technical data section with every clearance and fit, and step-by-step procedures for the cylinder head, crankshaft, timing gears, and both the Airesearch T-04B and Holset H2B turbochargers. The Tu-Flo 600 and WB 15 compressors get their own section too. Set cold valve tip clearance at 0.010 in inlet and 0.025 in exhaust, then pull the head setscrews to 136 Nm on the first stage. Guessing at decades-old specs from a forum thread is how blocks get scrapped. This PDF is bookmarked with a real text layer; search any spec, jump straight to the job, and get wrenching.

Perkins V8.640, TV8.640, AV8.640, ATV8.640 Common Problems This Manual Covers
Perkins V8.640 diesel cranks slowly and won't start in cold weather, white smoke when it fires
Check the fault finding chart on page 27 for low cranking speed and difficult starting. Test battery condition and starter connections, then bleed the fuel system until fuel runs free of air bubbles. Verify injection pump static timing is set at 16 degrees B.T.D.C., listed in the timing data on page 20, before condemning the pump.
Manual Section: Fault Finding p. 27Engine down on power under load, misfires and blows black smoke from the exhaust
Check the air cleaner restriction indicator before touching the fuel side; a choked element mimics fuel starvation. Service the element and bleed the fuel system following page 80, then pull the atomisers and test spray pattern. Torque the atomiser clamp securing nuts to 47 Nm (35 lbf ft) on refit so they seat squarely.
Manual Section: Fuel System and Air Cleaners p. 80Low oil pressure at hot idle, gauge reading drops once engine reaches operating temperature
Verify oil level first; the sump holds 40 imperial pints (22.7 litres) and a low reading skews everything downstream. Check the oil pressure relief valve and dump valve, covered in the lubricating system section starting on page 65. Drop the sump and clean the strainer if the valves check out; sludge starves the pump pickup.
Manual Section: Lubricating System p. 65Engine runs hot on long pulls, coolant pushing out of the header tank
Check drive belt tension and the tensioner pulley on page 74, then test both thermostats in hot water for full opening. Verify the system actually holds its full 50 imperial pints (28.4 litres); an air lock reads as overheating on the gauge. Inspect coolant pipe joints for seepage before pulling the water pump.
Manual Section: Cooling System p. 74Loud tappet clatter from both rocker covers, worse when the engine is warm
Adjust valve tip clearances with the engine cold: 0.25 mm (0.010 in) inlet and 0.65 mm (0.025 in) exhaust, using the procedure on page 31. Check the rocker shafts for wear and confirm oil is reaching the rocker gear while the covers are off. Persistent clatter after adjustment points to worn cam followers or valve guides.
Manual Section: Cylinder Head p. 31Frequently Asked Questions
What are the torque specifications for the cylinder head setscrews and nuts on the Perkins V8.640 engine?
The cylinder head setscrews and nuts should be tightened in the specified order to a final torque of 155 lbf ft (210 Nm) 21,4 kgf m. p. 30
Where can I find the torque specifications for the flywheel setscrews?
The flywheel setscrews should be tightened to a torque of 80 lbf ft (108 Nm) 11,1 kgf m. p. 92
What is the correct valve tip clearance for the inlet and exhaust valves on the V8.640 engine?
With the engine cold, the inlet valve tip clearance should be 0.010 in (0,25 mm) and the exhaust valve tip clearance should be 0.025 in (0,65 mm). p. 31
What is the lubricating oil sump capacity for the V8.640 engine?
The sump capacity is 40 imperial pints (22,7 litres) or 24 U.S. quarts. The level should be checked using the dipstick on level ground. p. 9
How often should the engine lubricating oil be changed?
The engine lubricating oil should be drained and renewed every 12,500 miles (20.000 km), 500 hours, or 6 months, whichever occurs first. p. 24
