Motor Cylinder
How do I know which type of cylinder heads are on my motor?
There are casting numbers on them, but what do i do with them? It says 6272990? The motor says 140154459 what type of motor is it also? i know its a 454ci GM Motor, but i want to be sure of the exact specifications. Thank you.
These should be rectangular port open chamber heads with 118CC chambers. 2.19 intake and 1.88 exhaust valves. Original on 425HP 427's starting in 1971. Good heads for stock cast iron heads.

Criteria For Choosing The Cutting Fluid In Hydraulic Environments
Three are the mainly widely established criteria for selecting the cutting fluid:
- The workpiece material structure,
- The tool composition,
- The functional conditions of the cutting process.
Frequently is used mineral oil emulsions in water (emulsions) in diverse percentages depending on the rigidity of materials and cutting conditions. For example, emulsions diluted (between 3 and 8% oil) has little power and lubricant are used only for slow work. As increasing the amount of oil, which can reach up to 30%, increases power and are suitable lubricant for high speed work on solid supplies.
The unmixed oils are rarely used at present, either at cost (minerals) or by their low resistance to oxidation (plant and animal). An exceptional case, particularly suitable for superior pressure work, it is the oil to molybdenum disulfide, with exceptional lubricating qualities.
Lubrication and cooling of hydraulic transmission
In general, hydraulic transmission (oleohydraulic) are widely used in heavy equipment such as, for example, backhoes, dump trucks, loaders devices, etc.., And are characterized by elevated power transmission through a working fluid, normally oil , flowing through a pipeline at high pressure and that gets communicated to the actuator for movement.
However, the pumping action, the steep intensification in pressure, flow through conduits, narrowing, control valves and elements of work (cylinder engines) results in a gradual intensify in fluid heat, quite pronounced in several cases where it can reach up to 300 bar pressure at duty cycles of long-distance during times of high operation. It is Important to Decrease the high temperature of the lubricate for the reason that, otherwise, would modulate its properties, drastically dropping its viscosity and lubricating as well as other components of the heating installation, which can turn into unusable if it exceeds particular high temperature values. The working fluid maintenance within the Best temperature levels to conserve and avoid its degradation requires installing temperature exchangers used for cooling water at temperatures between 20 and 25 C. In Specific cases, can be accomplished with a temperature exchanger air / oil.
It is well-known to conclude that in equipment and small power plants with probable stress levels relatively low, it is vital extra cooling of the working fluid, since the warm dissipation to ambient air through the circuits is sufficient to keep up the heat within the range recommended.
Lubrication and cooling pneumatic
In the pneumatic tools is in addition crucial to oil and cool the actuators that while working at low or standard pressure (up to 10 bar), do so at superior speeds due to low viscosity of air so that the waste of work items may become defendants. For this purpose, supply intakes machines such as saws, grinders, etc.., Installs a lubricator incorporating oil droplets into the air, thereby ensuring the lubrication.
Moreover, it is vital to examine air heat, which in this instance perform as a refrigerant and evacuate the air in the exhaust temperature generated by the relative movement and friction inside the actuators. The heat control is carried out air conditioning units at the compressor outlet.
Lubrication and cooling of internal combustion Mechanisms
The lubrication system consists of a pump that aims crankcase oil and distributes it to all points of importance.
In the two-stroke gasoline mechanisms adds a specified amount of oil to the fuel-air mixture entering the engine, thereby ensuring the protection of surfaces in constant contact.
Since the ignition happens at very high temperatures (200 to 300 C in the piston, for example) and the lubricant is unable to evacuate the high temperature in its entirety, it is crucial a special cooling system, although certain cases, such as bike engines, could be effected by air movement, it will normally be a system of forced water transmission, which incorporates a heat exchanger water-air (radiator) which can expand the efficiency of exchange using a heater.
In particular mechanisms it is crucial to also cool the lubricant itself by passing an oil-water temperature exchanger, which uses the water cooling circuit above.

These are all different pieces of equipment, and each is operated in a different way. There is no general "how to operate" procedure that covers them all.
Try getting on the internet and finding web sites for the specific pieces of equipment you are interested in. The manufacturers may have on-line operating manuals for some of these devices.
