What is the purpose of removing the cylinder Ridge?

When removing a piston from the engine block, it’s best to remove the cylinder’s ridge before removing the piston. Removing the ridge prevents damage to the piston ring groove lands during piston removal. The ridge occurs as the cylinder wall wears and appears just above the top of the compression ring.

What is meant by Ring Ridge?

A ridge is a ring of rings. The top limit of ring travel is above that portion of the cylinder. In a worn cylinder, this area is of a smaller diameter than the rest of the cylinder and will leave a ledge or ridge.

Is a ridge reamer necessary?

Yes, ridge reaming is absolutely necessary for your situation. No, don’t waste your time when the ridge is so small, and the same pistons will be used.

Why is it important to remove the carbon ridge from a cylinder before removing the piston?

Why is it important to remove the carbon ridge from a cylinder before removing the piston? It’s a good idea to remove the cylinder’s ridge before removing the piston from the engine block. The ridge can be removed to prevent damage to the ring. It is easy to remove too much material from the engine block.

What is compression ratio of IC engine?

Compression ratio, in an internal-combustion engine, degree to which the fuel mixture is compressed before ignition. A compression ratio of six means that the mixture is compressed to one-sixth its original volume by the action of the piston in the cylinder.

Can you remove a ridge from an engine cylinder?

It would seem that if I remove the ridge completely I run >the risk of undercutting and damaging the cylinder. Any advise? >Thanks. > I’m not sure ridge reamers have much place in an engine builders tool box. If the ridge is bad enough to cause trouble then you really want to be thinking about a rebore.

Why is there a ridge on the top of a cylinder?

A ridge reamer is used to remove the ridge from the top of the cylinder’s bore. The ridge is caused by the cylinder wall wearing from ring travel just above the top of the compression ring. This wear leaves the area above ring travel unworn. It’s best to remove this ridge before removing the piston.

When do you remove the cylinder ridge reamer?

Cylinder Ridge Reamer When removing a piston from the engine block, it’s best to remove the cylinder’s ridge before removing the piston. Removing the ridge prevents damage to the piston ring groove lands during piston removal. The ridge occurs as the cylinder wall wears and appears just above the top of the compression ring.

When do you cut out the upper cylinder Ridge?

There is a tool designed to ‘cut’ the ridge out and that should always be done BEFORE removing the pistons, so as not to damage the ring lands of the pistons that could occur if driving the piston out with the ridge in place.
