A grease gun works by applying grease to the bearing surface with the aid of a suction hose. Grease is pumped into the gun by suction. The gun may be reciprocating or linear. Reciprocating means that the spindle moves in a forward and back motion, while the linear type facilitates the application of grease over a long distance in a linear manner.
How does a grease gun work? To operate a grease gun one must first install a threaded attachment on the bottom of the fitting. The attachment should be a low resistance brass threaded rod or else it will not work. This is because grease tends to expand when compressed. One must then install a high resistance rubber or plastic coupler at the other end of this threaded rod.
Next, one must cock the pump so that a small amount of air is generated. This creates a vacuum pressure at the other end of the coupling, and it pulls the fitted rubber or plastic coupler outwards to allow some amount of oil to flow into the new cartridge. It also allows the new cartridge to be installed into the existing muzzle. The amount of oil in the new cartridge will determine how long the cycle lasts.
How do you maintain a grease gun? A normal maintenance procedure includes cleaning both the fittings and the barrel. However, some guns can also be maintained manually. First of all, one must thoroughly clean the entire housing, including the crankcase, spindle and ramshackle. After cleaning, one should inspect the fittings and barrel for any excess dirt.
If this is the first time you have greased the handle, you need to adjust the air pressure and air valve appropriately. For this purpose, you need to open the charging handle halfway and wait until the air pressure has been fully compensated for by the expanding pressure. In addition to this, you also need to open the air valve halfway to ensure proper lubricating. This is because if the air pressure is not adequate, the bearing seals will not properly perform their function.
Another important thing to consider is that if you have greased the cartridge properly, there should be a very small amount of visible oil left. To check for this, you should open the nozzle and observe the area surrounding the rotating wheel. The amount of oil will be visible. In case there is no oil, you can simply repeat the previous step. You also need to make sure that you have properly aligned the bearing seals before proceeding.
Before proceeding further, you should make sure that the air valve and the oil cap are open and that the grease gun nozzle is not blocked. This is because if any of these items are obstructed, the grease gun may not rotate properly. For this reason, it is important to ensure that all the above-mentioned steps have been done before proceeding. If not, you should open the cap and move the air valve to open the grease gun.
Then, you should attach the wrench to the appropriate side of the pump and turn it in a clockwise direction to start rotating the oil drum. As soon as the rotation is complete, you should check the direction of rotation by looking at the indicator in the greaser nipple. It is advisable to place a piece of paper between the pump and the grease nipple so that you can easily determine whether the rotator is engaging or disengaging. If you find that both are engaging, your work is almost done.
Next, you should place the battery-powered electric motor on the shaft and then turn it in a counterclockwise direction to start rotation of the shaft. Again, look at the indicator in the grease gun to determine whether the shaft is engaging or disengaging. If you find that both are engaging, your work is almost done. However, if you find that one of them is disengaging, you should continue to the next step.
The second step is to place the high pressure grease gun on the end of the shaft and slowly apply pressure onto the rod until the seal is released. After that, you should remove the rod from the shaft. Next, you should reconnect the pressure switch and plug in the motor. Turn the power back on and plug in the AC source. You should wait for a few minutes for the motor to warm up. When it does, you should test the high pressure setting to ensure that the pressure was successfully applied onto the rod.
Finally, you should test the quality of the old grease gun by shooting a couple of BBs through it. If the shot is not released within a few seconds, you should switch to using a new bearing. This is actually one of the simplest ways of repairing a broken bearing in the case that you cannot find the old grease gun parts.
