Disassemble, repair and assemble "Volgovsky" shock absorber

Collate can isolator, adhering to the following priority actions: Fix the shock in the grip of the lower mounting lug, move the piston in the up position. Then, a special wrench, unscrew the nut shell. Swinging motion of the upper part of the stem to remove it, complete with a piston cylinder. At the same time Take extra care in order not to damage the polished surface of the rod. Remove the slave cylinder from the tank and completely drain the fluid shock absorber. Fasten the grip rod for the upper mounting lug nut and remove the piston. Dismantle the piston with the details of the valve, as the guide and clip seal. All parts of the shock wash in kerosene or gasoline. Cleaned and dried parts, inspect, and mark those that require correction or replacement. In assessing the state of the valve assemblies of parts, pay special attention to the condition of valve edges, in the presence of scratches on his saddle, or on the working surface of the valve should be significantly wear or other defects, using the method of grinding, remove them. Replace parts of valves, if the inspection they found out the kinks and cracks. Absorber to collect in the reverse order, with the following details: Saturate a new shock absorber fluid seal of the foam before installing. Install a rubber seal rod in a holder so that the label "low" it was directed to the piston. Before you install a new gasket on the stem, the inner surface of it, which will be in contact with the rod, be sure to lubricate the shock absorber fluid. Cylinder with an already pressed into the hub / valve compression type in the tank. Then you need to pour the liquid absorber (at a diameter of 35 mm - 320 cm), with the top to fill the cylinder, and pour into the reservoir fluid balance. In order to prevent premature failure of shock absorber used to fill only a special shock absorber fluid. In the front and rear shock absorbers used shock absorber fluid (AF-12T) or spindle oil AU. Number of filled in the damper fluid must be in strict accordance with the volume filling of the absorber. The difference is deemed to be valid, may have values ??not exceeding ± 5sm3 (in case of non-compliance with these recommendations, the result may be a violation of the shock, and even internal damage). Insert the slave cylinder piston assembly with a rod, close the cylinder guide and then, carefully smoothing out of the end face of the guide seal the tank, tighten the nut shell. Flush a fully assembled damper before install it on the car. The process flow produce by moving the rod up until the force applied to it, will not be uniform along the entire length of the working stroke. This operation is necessary to remove residual air from all the cavities of the working cylinder of the shock absorber. With incomplete removal of air from the system, there may be "gaps" in the shock absorber.
