GENERAL
The Perkins A4.236 engine and the A4.248 engine are four-cylinder water cooled. direct injection diesel units. The A4.236 has a stroke of 127 mm (5.0 in.) and a nominal bore diameter of 98.42 mm (3.875 in.) the A4.248 has a stroke of 127 mm (5.0 in.) and a nominal bore diameter of 101 mm (3.98 in.).
Both types of engines incorporate overhead valves mounted vertically in the cylinder head. A gear driven camshaft located in the right-hand side of the cylinder block operates the valves via tappets, push rods and a series of rocker levers located on a shaft mounted on top of the cylinder head. Valves with oversize stems are available for earlier engines if excessive wear should occur in the cylinder head. Later engines feature a cylinder head with replaceable valve guides.
The cylinder block and crankcase form an integral casting and are fitted with full length replaceable flanged cast iron liners.
38
38
The aluminum pistons have a toroidial cavity in the head and are fitted with three piston rings on A4.248 engines. and five piston rings on A4.236 engines. The pistons are attached to their connecting rods by fully floating wrist pins retained by circlips. The big end bearings are replaceable and consist of a thin steel-shell lined with an aluminium-tin alloy.
The engine is lubricated by force feed. The oil is drawn from the sump via a strainer. by a rotary pump driven by the crankshaft via the balancer unit. The oil passes through a filter before being circulated under pressure around the engine.
The crankshaft is mounted in five replaceable aluminumtin alloy lined bearings held in position by cast iron bearing caps. Thrust is absorbed by four washers located on both sides of the centre main bearing cap and cylinder block.
A balancer unit is fitted to the cylinder block and driven via gears by the crankshaft. The oil pump is mounted at the front of this unit inside the lubricating oil sump.

GENERAL
Perkins A6.354.4 engine is a six cylinder, direct injection, water-cooled engine. The nominal bore is 98.4 mm (3.875 in.) and the stroke is 127 mm (5 in.).
The engine has overhead valves fitted vertically on the cylinder head. A gear-driven camshaft located on the righthand side of the cylinders operates the valves by means of push rods and a series of rockers fitted on a shaft located at the top of the cylinder head.
The cylinder block is fitted with removable. flanged liners.
The pistons have a toroidal cavity in the crown and are fitted with three piston rings. The pistons are attached to the connecting rods by means of gudgeon pins retained by circlips. The connecting rod bearings are removable.
The engine is pressure lubricated. The oil is drawn from the sump through a strainer, by a rotary pump driven by the fuel injection pump drive shaft.
The crankshaft is fitted on removable bearings held in position by bearing caps. End float is controlled by the four thrust washers located on both sides of the centre main bearing.

GENERAL
The coolant is circulated by thermo-syphon action assisted by a centrifugal type pump. The system is controlled by a thermostat which prevents the coolant from flowing through the radiator until the correct working temperature has been achieved, and a pressure-sensitive radiator cap, which. by allowing the radiator to pressurized, raises the temperature at which the coolant will boil. A fan attached to the front of the engine assists cooling by drawing air through the radiator.
The water pump and cooling fan are driven by belts, which is driven by a pulley attached to the front of the crankshaft.

GENERAL - OPERATING PRINCIPLES
The coolant is circulated by thermo-syphon action assisted by a centrifugal type pump.
Flow of the coolant through the radiator is regulated by two thermostats, fitted in parallal, in order to provide an optimum working temperature.
The radiator cap incorporates a valve set at 0.69 bar (10 lbf.in.2) which prevents the coolant in the radiator from boiling (raising its boiling point).
The capacity of the system is 19.5 litres (20.6 U.S. qts.).

Cleanliness must always be observed when servicing any component of the fuel system. Suitable caps or masking tape should be available for blanking-off open fuel connections as soon as a union has been removed. Do not use cotton waste or rag producing lint to clean out any part of the fuel system. When working with Diesel equipment, the hands should always be protected with a protective cream.
Servicing of fuel and air system components should be limited to the recommendations given in the following pages. This section of the Workshop Manual gives only partial details of the fuel system components. For more comprehensive details of the fuel system components. particularly related to servicing. see the Perkins and CAV Workshop Manuals.

GENERAL The p.t.o. is a proportional ... engine, two speed p.t.o. with the high flow linkage pump, reduction gears and the two-position control lever. The second speed being obtained by exchanging the p.t.o. shaft, 540 rev/min or 1000 rev/min.
The p.t.o. shaft projects rearward from the lower section of the centre housing and when not in use a screwed cap is fitted.
The front end of each p.t.o. shaft is supported by a needle bearing in the rear end of the linkage pump camshaft.

07 07
The drive, compounded reduction and driven gears are all supported on needle bearings.
The rear end of each p.t.o. shaft is supported by a ball bearing together with two seals; one of metal to exclude external dirt and a lip type seal to retain the transmission oil within the centre housing.
A guide tube assembly is fitted within the centre housing, which prevents transmission oil running out when the 540 rev/min or 1000 rev/min p.t.o. shafts are ex-changed. ' '

INDEPENDENT POWER TAKE OFF CLUTCH UNIT
GENERAL The independent power take off consists of a hydraulically actuated clutch unit whose engagement and disengagement is controlled by a two position spool valve mounted on the front end of the pto clutch housing.
The drive hub of the clutch is splined to the rear end of the linkage pump camshaft, while the clutch housing is connected to the front end of the p.t.o. shaft or the drive gear of the reduction gear by the clutch plate retainer external splines and retaining ring. The friction discs are splined to the drive hub and the
11

clutch plates are splined to the clutch housing, which also accommodates the Belleville washer and piston assembly.
Hydraulic pressure applied to the piston assembly closes the clutch plates to the friction plates, thus transmitting the drive of the linkage pump to the p.t.o. shaft or drive gear of the reduction gearing.
When the hydraulic pressure is released, the wave springs, fitted outside the friction discs and between the outer peripheries of the clutch plates keep these components apart.
