Features	Benefits
The bore of the liner is 4.5 inches. Because of the precision computer numerical controlled machine tools we manufacture our liners from, we can hold the bore dimension to -.0000/+.0015", and straight from top to bottom	This insures proper piston to cylinder clearance so the compressor runs as it was originally designed. If the bore is too small the piston will score the liner and might seize in the liner. If the bore is too large the piston will knock. Also, when running in an oversized bore the compressor will operate as if the liner or piston rings are worn out and gas will leak through the piston ring end gap.
CECO specifies a 20-32 cross hatch hone in the bore, honed at 120 degree angles	This type of hone is very compatible with the piston rings. It is a good surface for retaining oil to reduce piston ring to liner friction while also allowing the piston and rings a smooth surface to run on. If the hone is too smooth, the rings will not run in properly and the gas will leak around them. If it too rough, the piston and rings will wear out too quickly.
We use Class 30 cast iron as our liner material	Gives you strong surfaces that resist scoring that steel might allow. Class 30 means the cast iron has a tensile strength of 35,000.
We lap the top rim where the safety head meets the liner to a 4-6 RMS lapped finish	This, along with the same lapped finish in the safety head, gives you a very good seal between the parts. If you do not have a good seal between the liner and safety head your refrigerant will leak back into the suction stream and not be compressed out through the safety head assembly.
All of our radial dimensions are held to .002" and other dimensions are held to .005"	This gives you good compatibility with all of the liner mating parts to assure proper fit and function.
CECO utilizes state-of-the-art inspection equipment used for in-process and final inspections	All parts are 100% inspected assuring consistent, "OEM Superior"sm quality.
