5/04/2019 taking the piston out

Today we took off the crank shaft gear. We also took off the camshaft and crankshaft and cam followers. After that we loosened the connecting rod and were ready to take the piston out. But there was a fire drill and we had to wait until after lunch. After lunch we attempted to take the piston out but the piston had smoothed the inside of the cylinder and the top had made a ridge and we were really struggling to get it out. We tried using a screwdriver, a hammer, and pliers but it wasn't working. So Mr Venter just knocked it out using brute force. We also spent some time cleaning the piston and other parts. We only have the intake and exhaust valves left to remove.
