Prelubrication

Two methods ofprelubing

Continuous

Intermittent

Let students make the qiuz (see transparencysection). Give them about 5 min. and then showthem how the system should look like. Explain lubesystem and the function of the differentcomponents.

Oil system provides a constant supply of 85 C (185F) filtered oil at 430 kPa (62.4 psi) pressure.

An oil priority valve regulates oil preesure at thecylinder block oil manifold rather than at the oilpump. This makes the oil manifold pressureindependent of oil filter and oil cooler pressuredrops.

Oil to the oil pump passes through a 650 micron(0.025 in.) screen located between the suction belland the suction tube.

Oil temperature regulators direct the oil to coolersat oil temperatures above 85 C ( 185 F).

From the 20 microns (0.78 mils) final filters the oilflows through the priority valve to drilled oilpassages in the cylinder block.

Prelubrication is required for all 3600 enginesbefore each start.

Two methods are available: intermittent andcontinuous.

Continuous prelubrication occurs in stand-bysituations.

Intermittent prelubrication occurs for a shortinterval preceding engine start and provides oil to

all the engine bearings. A pressure switch andstarter interlock prevent starter operation with lessthan 10 kPa (1.5 psi) lube system pressure.

5Page:

Priority valve

The priority valve senses filtered oil pressure and bypasses or dumps unfilteredoil back to the oil sump to control the engine oil pressure.


18/57

Centrifugal filters



6Page:

The centrifugal oil filters extend the life of the oil filter elements and remove someparticles smaller than the oil filters will normally take out.

The centrifugal filters receive 3-4 % of the oil pump flow.

The flow of oil through the jets causes the rotor assembly to rotate at about 4000

rpm.

Oil flow through each filter is 17 L/min. (5.5 gpm) and the dirt capacity is 3.6 kg (8

lbs.).

The centrifugal filters should normally be cleaned every 1000 hours.

Slides

LEGV0928 - #19

Show slides and explain the functions of thedifferent components of the lube system.

Oil pump - the oil pump is driven approximately 1.5times engine speed. The components of the pumpare the same for both standard and reverserotation. An oil pump can not be removed from astandard rotation engine and installed directly to areverse rotation engine or visa versa. A single

dowel pin in the mounting flange prevents thepump from being rotated 1800 degrees andinstalled.

Oil pump - standrad rotation.

Oil pump - reverse rotation.

Air operated prelube pump.

Electric prelube pump - pumps can be providedwith 115/230 VAC, 50/60 Hz single phase motor.They also can be equipped with 24 VDC or 60/70VDC motors. Higher voltage 3 phase motors areavailable for continuous prelubrication systems.

Oil temperature regulators.

Oil filters - (Duplex filters) There are two oil filterhousings on all 3600 engines with three replaceablefilter elements in each housing. An oil filter changevalve allows the filter elements for each filterhousing to be changed separatly while the engine isoperating. The maximum change period is 1000hours or when the oil filter pressure drop reaches104 kPa (15 psi).

Instructor notes

LEGV0928 - #59

Explain general air flow of the engine and showslides about engine aftercooler.

For optimum engine performance and low fuelconsumption, two exhaust manifold designs areused on the 3600 family of engines.

A divided or split exhaust manifold system isinstalled on the 3606 and 3612 diesel engines. Theturbocharger(s) used with this manifold design hasa double entry inlet.

A single larger diameter exhaust manifold designwith single inlet into the turbocharger is used with3608, 3616 and all spark ignited (gas) engines.

In-line aftercooler core - mounted on theleft side ofthe engine.

In-line cylinder block - with cast-in inlet manifold.

Vee engine aftercooler core - mounted above thecenter of the vee.

Location of vee engine aftercooler & air shutoff. Anair shutoff is available for installation at theaftercooler inlet. The air shutoff is closed only whenan overspeed occurs or when an emergencyshutdown is initiated.

Instructor notes

Camshaft

Talk about camshaft segments and journals.

The camshaft is running half the speed of thecrankshaft. The camshaft is with the help of pushrods and rocker arms activating the air inlet andexhaust valves and the unit injector.

The camshafts in all 3600 engines are segmented.Each cylinder has its own segment but all the

segments are the same. On Vee engines thesegments in the left side are different than those inthe right side.

The segments in the in-line engine will be the sameas the segments in the left or rigth of the Veeengine, depending on whether it is a standard orreverse rotation engine. Therefor there are basicallytwo camshaft part numbers to service both in-line

and Vee distillate fuel engines. Heavy fuel enginecamshafts may be different.

Camshaft segments installed on diesel enginesbefore mid-1990 have thinner flanges and spacers.The bolts are also smaller.

IV. COOLING SYSTEM


34/57

CHAPTER : Cooling system


2Page:

Instructor notes

Two coolingsystems

Caterpillar is providing two cooling systems:Combined circuit cooling & separate circuit cooling.

Temperatures in the two systems are the same.

50 C (122 F) nominal water temperature to the ACand OC (DFE).

32 C (90 F) nominal water temperature to the AC

and OC (HFE).

90 C (194 F) nominal jacket water temperature to thecylinder block circuit (DFE).

93 C (199 F) nominal jacket water temperature to thecylinder block circuit (HFE).

85 C (185 F) nominal oil to bearing temperature.

Over time, as the performance of the heatexchanger decreases due to fouling, the watertemperature to the AC will increase. At higherambient conditions, the water to the AC and OC isallowed to rise to 65 C (149 F) for DFE or 38 C (100F) for HFE maximumbefore engine deration isrequired.

Advantagecombined system

The combined circuit system is also known as thesingle circuit - two pump system.

The main advantage of the combined circuit systemis that it requires only one external cooling circuitwith only one heat exchanger or radiator. There isless coolant and cooling system piping can berelatively simple.

Instructor notes

Makeup line(separate circuit)

The only connection between the AC / OC circuitand the engine jacket water circuit is a makeup linethat goes from the expansion tank to the waterpump supply line. This line keeps the AC / OCcircuit filled when it shares the expansion tank withthe jacket water circuit. There is no active flowbetween the circuits.

The total radiator surface area may be 20 % less at45 C (110 F) ambient and up to 30 % less at higherambients, when compared to a combined circuit.

Maintains nominal water temperature to the AC andOC while rejecting heat from the cylinder block andheads at higher temperatures.

The total external flow is approximately twice theexternal flow of the single circuit system. Half of the

flow (high temperature circuit) must be cooled tonominal jacket water temperature and the lowtemperature circuit cooled to nominal AC / OCwater temperature.
