Where is the piston on the exhaust bridge?
Slowly turn the engine over until the bottom ring groove (or the only ring groove if your piston has only one) on the piston is at the top of the exhaust bridge. You can look through the exhaust port of the cylinder to help know when the piston is in the correct spot. 4.
How is the intake pipe opened and closed?
The intake tract is opened and closed by a thin disk attached to the crankshaft and spins at crankshaft speed. The fuel/air path through the intake tract is arranged so that it passes through the disk. This disk has a section cut from it and when this cut passes the intake pipe it opens, otherwise it is closed.
How do you remove a piston from an engine?
Go through the exhaust port with a pencil and trace a line on the piston skirt for each side of the exhaust bridge. Trace two lines on the piston; one on each side of the exhaust bridge. 5. Once the lines are traced and visible, remove the cylinder and the piston. 6.
Where is the major thrust face on a piston?
The major thrust face is the side of the piston that receives the thrust on the power stroke. As viewed facing the front of the engine, if the crankshaft is rotating clockwise, the major thrust face is on the left side of the cylinder (the exhaust sides of the right/ passenger cylinders; and the intake sides of the left (driver) side cylinders.
What causes damage on the intake side of a piston?
This damage was only found only on the intake side of the piston. This is typical for damage caused by intake debris. The other side of the piston is not exposed to an intake port, so it isn’t affected at early stages.

When is the intake pocket on the right side?
Typically, a ‘right’ is when the intake pocket is on the right side of the piston when looking at the top of the piston with the valve reliefs up.” Piston orientation is extremely critical when you look at asymmetrical valve reliefs, but other aspects of the piston design are also affected.
