turbogrill Posted January 10, 2018 Report Share Posted January 10, 2018 Hi, This should be basic stuff but I want to make sure I get it correct and don't messup my new rebuild. First time I am assembling an engine. According to the manual two things need to be done bore installing the head: - Camshaft on the head should be aligned to a mark, this is easy. (I guess the mark is 0 degress TDC) - #1 cylinder needs to be TDC, this is where I am a bit confused. When finding TDC without the head there is no concept of compression stroke vs exhaust? I just need to make sure the #1 piston is at it's topmost position? I don't have to worry about if it's 0 or 360 degrees in the 720 4 stroke cycle. This only matters once the camshaft is installed, correct? Is finding TDC visually good enough or do I need a dial indicator? (maybe this depends on the engine..)
