Wheel Valve Air Filter Change
Figure 17 shows the location of the air filter in each
wheel valve. This filter must be replaced whenever
the tire or wheel valve is serviced and at every tire
change. Use the illustration as a reference in complet-
ing the air filter replacement as follows:
1. Working quickly to prevent air loss, remove the tire
hose from the outlet port of the wheel valve. Cap
hoses to prevent air loss. If outlet port has an
adapter, remove it also.
2. Use a screwdriver to unscrew the air filter from the
wheel valve. Discard the used air filter.
Note: Air filters should not be cleaned or reused, always
replace with a new air filter.
3. Install new air filter into wheel valve outlet port.
4. If wheel valve is to service a dual set of tires, prepare
the wheel valve in the following manner. If only
servicing a single tire proceed to step 7.
