What is an EMD power pack?
The term power assembly refers to an Electro-Motive Diesel (EMD) engine sub-assembly designed to be “easily” removed and replaced in order to restore engine performance lost to wear or engine failure. This increases engine value, reduces downtime and allows the engine to be returned to true new engine performance.
What are power assemblies?
Power Assemblies is a manufacturer of portable power products for generator dealers, electrical and general contractors, banks, hospitals, and the military. The company was founded in 2006 and has locations in Las Vegas, Nevada, Bend, Oregon and Pompano Beach, Florida.
What is assembly of engine?
An engine assembly is the most complete replacement choice. An engine assembly takes the long block and typically adds intake manifold, valve covers, oil pan, water pump, and crank pulley. Some rebuilders will also include exhaust manifolds and ignition distributor.
What is a piston assembly?
Piston components extend all the way from the part bordering the combustion chamber to the end that connects to the crankshaft. Collectively, these parts make the piston assembly. These are the components we will focus on.
What is engine disassembly?
The transmission and clutch are removed. All remaining accessories are removed from the engine and stored in a safe place. Engine disassembly is preferred to be done on an engine stand; however it can also be carried out on blocks on a clean floor.
Is connecting rod and piston rod the same thing?
In a piston engine, a piston rod joins a piston to the crosshead and thus to the connecting rod that drives the crankshaft or (for steam locomotives) the driving wheels. The term piston rod has been used as a synonym for ‘connecting rod’ in the context of these engines.
What is a rod cap?
A rod cap is the removable section of a two-piece connecting rod that provides a bearing surface for the crankpin journal. The rod cap is attached to the connecting rod with two cap screws for installation and removal from the crankshaft.
How do you disassemble a car?

What do the top two piston rings do?
The top two rings— known as compression rings— are primarily for sealing the combustion chamber. The bottom ring— known as the oil control ring— is primarily for controlling the supply of oil to the cylinder wall, in order to lubricate the piston skirt and the oil control rings.
What is the purpose of the piston skirt?
The skirt consists of space for gudgeon pin which transmits power to the connecting rod. The skirt also helps in transferring the side thrust produced by the connecting rod. The piston consists of rings grooves for fitting piston rings. The landing of piston rings is hardened and plated with chrome to reduce wear.
