Step 1: Remove the shell
Take off the shell, just unscrew the top four cleat screws, if there is sand on the screws, apply some waste oil can be easy, if not consider the wind cannon, it is not a matter for the wind cannon.
Step 2: Remove the cylinder block
Take apart the top four long rod screw caps, the hammer can be split, the top is the nitrogen chamber, the hydraulic oil to push the piston up to the nitrogen chamber, to reach a certain pressure, push the piston to produce energy to hit the drill rod, and repeat the movement. The port has a sealing ring, pay attention to check.
Remember: Remove long bolts must first put nitrogen off, to prevent injury.
Step 3: Remove the piston
Generally, the piston is removed to the end of the nitrogen chamber, and there is a piston stop ring sealed behind it, which can be removed by tapping with a hammer.
After taking out the piston, you can see the sealing ring of the middle cylinder block, the ordinary hammer is generally composed of two sealing rings plus a cup buffer, the outer one is a dustproof sealing ring, the inside is an anti-seepage oil, and the cup is inside. When replacing the seal ring, you must polish a good tool yourself, it is best to use a steel wire or a hard long tool to polish, I am using a long small hex to polish, you must beat the head into a sharp cone, so that it is easier to pull the seal ring out.
Step 4: Install oil seal
It is best to clean the cylinder with gasoline, blow with gas, take out the front Y ring, the inside Y shape inward, and the dust ring shape outward. The back end is a gas ring, two oil rings, the oil ring with O-ring, removed together when replacing, after loading in with a cylindrical object to press the seal, to prevent uneven, when installing the piston damage.
Step 5: Install the piston
When installing the piston, apply a layer of lubricating oil first, and then slowly put it in, gently pay attention not to hurt your hands, put the piston in place, and then install the rear end of the piston stop ring, the best use of butter to stick the O-ring when installing the stop ring, to prevent misalignment. Install the long bolts into the middle cylinder block, and then install the nitrogen chamber. After the screw cap is set, it can not be played with the wind cannon, it should be tightened manually, the wind cannon may cause the nitrogen chamber to deform and leak, and after the screw cap is tightened diagonally, the kilogram wrench is used to tighten it to achieve the same pressure of each screw. Put the splints in, and you're done!
