Taking apart an old lawnmower V2

One Oil stained driveway later:

This is the motor of the lawnmower.
I explained how it works in the last post
Here’s a link!

This is the crank case breather. The crank case breather lets the crankcase have different pressures at different times. It helps the engine run with less resistance.

This is the crank case. This exposes the cam shaft and the crank shaft I’ll explain that next:

This is the crank shaft. This makes the piston go up and down. This makes the motor spin.

This is the cam shaft. The cam shaft pushes two rods that go up and down that open valves that let the exhaust out and the air inside of the motor. here’s a gif to explain it:


It’s basically just a little knickknack now.
I added a few Legos and rubber bands at the top to mimic valve springs.

Well now you know what’s inside of a lawnmower motor.

Have a great day everyone!
