Warning | Risk of injury caused by pinching or crushing when working on springs or spring bodies that are under tension | Use only approved tensioning devices; additionally screen off hazardous area if necessary. Check special tools for damage and proper operation (visual inspection). Wear protective gloves. | |
1 | Slightly compress the cover (9) of the membrane cylinder | Use a press or suitable device. | |
Mark the mounting position of the cover (9) and of the fastening strap (12) on the cylinder (5) so that these can later be assembled in the same positions. | |||
Holding device | |||
2 | Loosen the nut (10) and remove the screw (11) and the fastening strap (12) | ||
3 | Remove the cover (9) and the diaphragm (8) | Release the press pressure. | |
4 | Fasten the piston (7) to a vise and loosen the forked rod (3) a few turns | Knorr brake cylinders | |
Use aluminum guards on the jaws of the vise. | |||
5 | Compress the cylinder (5) against the spring (6) and manually unscrew the forked rod (3) | For Wabco brake cylinders, where the forked rod (3) is welded to the piston (7), remove the sealing ring (2) to remove the forked rod (3). | |
6 | Remove the piston (7) and the spring (6) from the cylinder (5) | Relieve the pressure on the spring (6). | |
7 | Remove the hood (1), the sealing ring (2) and the plugs (4) from the cylinder (5) | ||
| Clean | ||
8 | Wash the parts and check them for damage and wear | Use a suitable product to prevent damage to the rubber and plastic parts of the component. | |
| Assemble | ||
9 | Mount all three covers (4), the sealing ring (2) and the hood (1) on the cylinder | The repair kit parts should be replaced at each disassembly. | |
The bottom hole of the cylinder (5) should be open. | |||
The internal parts of the cylinder (5) and the parts to be assembled should be free of grease or other lubricant. | |||
10 | Fasten the piston (7) to a vise and install it on the spring (6) and the cylinder (5) with the forked rod (3) | Knorr brake cylinders. | |
Use aluminum guards on the jaws of the vise. | |||
11 | Screw the rod (3) to the piston (7) by pressing the rod until you notice that its end has touched the bottom of the threaded part of the piston | Apply a chemical lock to the thread on the rod (3). | |
For Wabco brake cylinders, where the forked rod is welded to the piston, the piston, mount the piston on the cylinder, then install the sealing ring (2). | |||
Auto Lock | |||
12 | Mount the diaphragm (8) and the cover (9) on the piston (7) | Apply talc to the diaphragm (8) and slightly compress the cylinder (5). | |
13 | Mount the strap (12) by positioning it together with the cover (9) and install the screw (11) | Place the cover (9) and the strap (12) by aligning the marks made during. | |
After tightening the screw (11), tap the strap (12) lightly to ensure the perfect seating of parts. | |||
