LEAK TEST PROCEDURE

Service repair no - 60.50.35

If 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 STC1090.

1. Ensure system is fully pressurised.
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 eg: air spring, air drier is leaking,

rectify by fitting a new component.

5. If an air pipe connection is leaking cut 5 mm off

end of pipe. Fit new collet.

See Repair, Air
