DIY KAMAZ energy storage repair

The content of the article “Do-it-yourself repair of KamAZ energy storage devices” will start with theory, we will find out what energy storage devices are, what they are made of and how they can be repaired with our own hands. At the end, you will find a practical video on repairing energy storage devices.

Several types of energy storage devices are used on a KAMAZ vehicle. They all have three parts. 1. The lower part is attached to the brake caliper bracket with M16 studs. 2. The middle part is made of aluminum alloy and is connected to the lower part by a two-bolt clamp. 3. The upper part is a steel glass, connected to the middle part by 8 M8 bolts.

Before repairing the KamAZ energy storage device, it is necessary to clean, wash and dry. Before disconnecting the lower part from the middle, it is necessary to supply air to the parking brake chamber with a pressure of at least 5 atm. In order to drown the working rod and prevent the spring from firing, then remove the clamp and remove the rubber diaphragm. Then turn off the air supply and unscrew the plug of the working rod with a wrench No. 36. Re-supply air to the parking brake chamber. Inside the stem there is a restraining bolt with a support bearing, which is secured with a retaining ring.

We continue to reanimate KAMAZ further and, having removed the retaining ring with the help of an awl, we release the stem for further disassembly. This is followed by an operation for which either a hydraulic press or a special clamp should be used. Having tightened the stem with a press or a clamp, thereby preventing the parking brake spring from firing in order to avoid injury, unscrew the bolts securing the upper glass from the middle part.

Then, relaxing the clamp (press), release the spring. If, when air is supplied to the parking brake chamber, it is not possible to sink the rod, you have to sacrifice a glass by drilling a couple of holes at a distance of 60 mm from the middle part. Using the same clamp or press, sink the rod to its full depth and insert stop pins into the drilled holes (bolts of at least 8 mm can be used), preventing the piston from returning independently. By removing the retaining ring inside the stem, you can get rid of the stop fingers, also using a press or a clamp. Further, according to the previous scenario, we remove the order book.

After cleaning, troubleshooting parts, replacing necessary parts and a repair kit, the assembly is carried out in the reverse order with the implementation of safety measures. After assembly, the operation of the finished energy storage device is checked using a compressor.

The spring energy accumulator (Fig. 280), after removing the hose and disconnecting from the pneumatic chamber, should be disassembled in the following sequence:

• unscrew the pusher 11 (Fig: 281, a) and remove the O-ring 12 from it;
• unscrewing screw 19 from cylinder 15 by a few turns (by about 5 mm), unscrew the nuts 9 of the bolts securing the flange 10 to the cylinder 15 and separate them;
• remove O-rings 6, 7 and 8 from the flange;
• screw the screw 19 until it stops and install the cylinder in the device (Fig. 281, b) so that the stop 21 of the device covers the screw head, and, carefully rotating the handle 22 of the device, compress the spring 5, while the depth of the piston 14 deepening into the cylinder 15 should not exceed 60 mm;
  
• having sunk the package of parts 2, 16 and 18 (Fig. 281, c) outside the rubber ring 1, remove the retaining ring 17 from the screw 19 with a special tool;
• release the piston 14 until the spring 5 is completely relaxed by carefully rotating the handle of the device in the opposite direction;
• removing the cylinder, piston and spring from the device, remove the remaining parts 2, 16 and 18 in it (Fig. 281, d);
• remove guide ring 3 and seal 4 from the piston;
• remove the spring 5;
• remove the rubber ring 1 from the screw, unscrew the screw 19 from the cylinder and remove the sealing washer 20.

Before assembly, all rubbing parts should be lubricated with a thin layer of CIATIM-221 grease. The assembly should be done in the following sequence:
