Stripping an Engine.

Today we worked on stripping down engines and learnt about the four-stroke engine cycle. we aligned the timing with the TDC (Top Dead Centre) and the BDC (Bottom Dead Centre), Removed the rocker cover and then dismantled the head, followed by the engine block. We learnt about internal combustion and how the fuel and air mix in the Combustion Chamber reacts when the spark is fired. All in all a good day and learnt alot of new things and can't wait to get back into the workshop tomorrow to begin rebuilding the engine!

Timing the engine to align with the TDC


This is the timing for the crankshaft, shows the notch aligned with TDC


The head with rockers removed.


The rockers, Top is the intake side and bottom is exhaust side.


Removing the head bolts, I started from the center and worked my way out.


Using the valve spring clamp to remove the valves from the head.


Valve seals, used to prevent oil from leaking into the combustion chamber.


The crank shaft after i removed the pistons.


Oil catch can.


Pistons, crankshaft brackets and thrust washers, ready to remove the crankshaft.


The crankshaft after removal.


The oil pump which I removed so I could take out the crankshaft.


oil sump, Had to remove to get to the pistons and crankshaft brackets


The valves from the head, top is intake and bottom are exhaust, separated to make sure I don't get them mixed up when i rebuild the engine
