The Leak Test
The purpose of a leak test is to make sure the unit is airtight. To
perform a leak test use the leak test fixture from the table below. If the
tool is not available, the gearbox must be sealed to perform the test.
This can be accomplished by replacing one of the oil plugs in the cover
with an air chuck.
DO NOT EXCEED 10 PSI PRESSURE DURING
THE LEAK TEST.
Higher pressure will create a false sealing effect in
assemblies with lip-seals. The unit has a leak if the pressure gauge
reading on your leak check fitting starts to fall after the gearbox has
been pressurized and allowed to equalize. Leaks will most likely occur
at the pipe plugs, the main seal or wherever O-rings or gaskets are
located. The exact location of a leak can usually be detected by
brushing a soap and water solution around the main seal and where
the O-rings or gaskets meet on the exterior of the unit and then
checking for air bubbles. If a leak is detected in a seal, O-ring, or
gasket, the part must be replaced and the unit rechecked. Leak test at
10 psi for 20 minutes. If the assembly has brakes do not plug any of
the brake ports as this may be an alternate leak path. Also if the
assembly does not have a brake that port needs to be sealed as there
are not brake seals.
