Taper is the wear of the cylinder bore that causes that bore to be cone shaped or "tapered"
This caused by several factors including:
And many other factors
Ovality and Taper Guages are used
To measure bore taper
Wear from high mileage.
The maximum amount of cylinder taper allowed in engine cylinders is typically around 0.001 inches per inch of bore diameter. Excessive taper can lead to poor piston ring sealing and increased oil consumption.
By definition, a cylinder has two equal circular (or elliptical) faces and a uniform cross section. Therefore, a cylinder cannot be tapered.
worn rings , low compression , cylinder bore taper, cracked pistons , cracked cylinder heads between head gaskets, could be many things causing oil to many things breather
The purpose of measuring taper angle is to obtain taper angle
This is the formula for calculating a taper: Large diameter of the taper minus the small Diameter of the taper divided by the length of of the taper will give you the taper per inch. You will also need to know the included angle of the taper if you ar cutting this taper. This formula would be Tangent of the included angle divide by 2.
cylinder stop drag
This means that it is the opposite of the normal direction that a taper goes. Example; If a normal taper goes to the left, a reverse taper goes to the right.
A taper is an Elizabethan word for a specific kind of candle.
The taper, per foot, is 0.0896
