Leak Test Procedure
LEAK TEST PROCEDUREIf an air leak is suspected the use of a proprietary leak detection spray is recommended. This procedure should also be used where pneumatic components have been disturbed.
The spray used must have a corrosion inhibitor, and must not cause damage to paintwork, plastics, metals and plastic pipes.
Recommended leak detection spray is GOTEC LDS. This is available under part number STC1 090.
1. Ensure system is fully pressurized.
2. Clean around area of suspected leak.
3. Using manufacturer's instructions, spray around all component joints and air springs, working systematically until source of leak is found.
4. If a component e.g.: air spring, air drier is leaking, rectify by fitting a new component.
5. If an air pipe connection is leaking cut 5 mm (0.2 in) off end of pipe. Fit new collet, refer to Air Line (Level Control)/Service and Repair/Disconnect and Connect Air Pipes Service and Repair
6. Reinflate system, carry out leak test.
