In a internal combustion engine, a cylinder ridge is an unworn area around the top of the cylinder wall. In that engine, the piston moves up and down in the cylinder, and the rings seal the piston in that cylinder. But the rings are spaced "down a bit" from the top of the piston. And when the piston reaches top dead center in the cylinder, the rings haven't gone all they way to the top of the cylinder. They end up wearing the cylinder out "underneath" that top area. In other words, it's the top part of the cylinder that is not in contact with the piston rings. It's the "unworn" part, if you will.

Should the cylinder ridge be removed before the piston?
No, you dont need to remove the cylinder ridge before. I never have and i replace them all the time.
What step must you perform before removing the piston from the bore to prevent damage?
Depending on the amount of wear in the cylinder, there may be a ridge at the top of it. If there is much of a ridge, the rings in the piston will catch on this and possible damage the piston. The ridge can be removed with a ridge reamer.
Definition of ring ridge?
The portion of a cylinder above the top limit of ring travel.
What tool is used to removed a piston?
the tool you are looking for is called a piston remover, sold at every local auto zone As the rings in the piston wear on the wall of the cylinder, a ridge forms at the top of the cylinder. This has to be removed with a Ridge Reamer. It cuts the ridge down until the cylinder is smooth otherwise the rings in the piston would catch on it and the piston cannot be removed. Once the cylinder is smooth, you can tap the piston out using the handle of a wooden handled hammer. To install the piston back in, you use a Ring Compressor that squeezes the rings into the grooves of the piston. Put lengths of plastic tubing over the Rod Bolts so that you don't nick the crankshaft and tap the piston into the cylinder with the same wooden hammer handle.
How do you change a bent rod in a 1997 Blazer?
if you meant a cylinder rod then you must take off the oil pan gasket and remove the oil connecting rod cap bearings to the cylinder rod- they cylinder must be removed from the top of the engine- to do this you must remove the cylinder head- you must use a ridge reamer to clean the ridge then remove the cylinder and rod from the engine - there is usually a reason the rod is bad- check bottom pan for damage to the bearings and check the cylinder for scoring or damamge- replace any bearings or connecting rods that are out of spec by using a plasigate you can check lower bearings and cap bearings check specs on piston rings and cylinder walls
What is the maximum cylinder wear on a Chevrolet 350 engine?
If you have to ream the ridge to get the old pistons out, you probably need to bore the cylinders and install oversize pistons. This assumes it was taken apart in the first place because of low cylinder pressure or excessive oil consumption (ie: worn rings). If there's not enough ridge to prevent you from pushing the pistons out of the bores, you can probably hone it out and re-ring the old pistons. If there is a ridge at the top of the cylinder, you need to bore it. The general consensus is that a rebuilt engine will wear out rapidly if there is any amount of taper. If you can catch a fingernail on the ridge, it's too much The upside is, if you bore it, put in new pistons and polish or turn the crank and replace the oil pump, you effectively have a new lower end and it should last 200,000 miles if properly maintained.
