CHONGQING TIGER CO.,LTD.

Instructions
1.Lower the cylinder head carefully onto a valve seat and guide machine and align it so it's perpendicular to the machine's core drill. Clear away all debris with a shop rag.
2.Drill into the first valve guide with the machine's core drill. Once you've reached the desired depth, swap the drill bit for a reamer head. Continue drilling to create a more defined hole. Repeat this process on every hole until you've reached the desired width and depth, then use a brush to clear out each hole.
3.Pour some lubricant into each hole to make it easier to fit the valve guide then dab some lubricant onto the guides themselves. Run a hand reamer through the holes to make sure they are the right diameter.
4.Install the valve guides into the holes in the cylinder head with an air tool although it is also possible to install it by hand. If you use the tool, make sure to set it to its lowest air pressure setting, and you may want to use a plastic washer or O-ring to avoid damaging the valve guide. The replacement guides should be the same length and dimensions as the ones you took out of the intake so you won't have to adjust them before installation.
5.Clear away any metal filings from the cylinder head's surface with the rag.

Valve
    The main technical parameters: The valve adopts the precision forging of transitional arc and high-speed helix polishing. The chassis of valve adopts vacuum welding and ion spray weld or ion welding wire. The bimetal of valve rod frictionless and weld, inscription plating on the surface. End face with embossing, high frequency cap quenching, lock clip trough hydraulic and grinding, whole valve shot blast, abrator, soft nitride tensionprocess,the process and design as well as assembly lines of valve are harmonized well with high efficiency and no abrasion and no leakage. At present we have the main equipments. Such as: Steeples Rotary Preheating Computer Control, Heating Processing Solution, Soft Nitride Equipment, Digital Control Rapid Non-mandrel grinder, Digital Control Precision Grinder Special for Valve, Digital Control Lock Slot Grinder Model Grinder. Computer Rapid Rotary Polisher, and Vacuum Welder, etc.
    We have set up the detecting room for physic, chemical, measurement and metallographic, it is equipped with micro-computer circular instrument, projector, and air sealing leaking testing instrument, ultrasonic flaw detector, universal tool microscope, and metallographic microscope etc. equipment. All these equipment can meet the demands for production control, quality testing, as well as users'.
