Working with the fixture

Bolts, nuts, screws, it is often difficult to loosen because of rust. Dampen a fitting kerosene impregnation with oil or other similar liquid and leave it on for a while soaking. Screwdriver or a key stroke type can help in this situation. If it does not work, gently heat the place of the threaded connection. Only as a last resort should use a chisel or a hacksaw. To unscrew the pin, use the following method. Screw the pin on the two nuts, one above the other. Tighten them together. After that you can unscrew the stud for the bottom nut by turning the key. If the bolt or stud came off below the surface to which they are screwed, they can try to uninstall using the extractor pins. Stud extractor is similar to tap left-handed stride. Extractors are usually available in sets for different diameters of the studs. In order to unscrew a broken stud, it is necessary to drill a hole, then screw the extractor into a corresponding diameter. Extractor screw into the hole until it jammed (it has a conical shape) and turns them a broken pin. Before screwing the studs, screws or bolts in the housing bore, make sure that there is no oil, water or other liquid. Hydraulic pressure, which is formed by screwing the studs or bolts in the housing bore, if there is fluid, can lead to the destruction of the body. When turning the castellated nut must be tightened its required torque, then loosen it a quarter turn, and then to the nearest dovernut shplintovogo holes. We should not turn away the castellated nut to align the holes shplintovye, unless stated specifically in the assembly instructions. If you need to check whether a bolt or nut is tightened, loosen them a quarter turn and then retighten the specified torque. Such a test can not be done if a bolt or nut were dovernut the desired angle after tightening wrench. For some fasteners, such as nuts and bolts of the cylinder head to indicate no torque as the final stage of tightening, and the angle at which the fastener must dovernut. Typically, these bolts or nuts wrapped in a certain sequence is relatively small torque, and then to the required angle dovorachivat in one or several stages. Do not forget to install washers under the fasteners when they are rotated relative to the body or parts when tightening. Splint replacement fixture must always use new, suitable for the size of the hole. If the fasteners were applied sealant, it must be removed with a wire brush and solvent. After assembly, this place must apply a new composition.
