5.5 INFLATION AND PRESSURE RELIEF VALVES
INFLATION VALVE - DISASSEMBLY
A - Partially loosen the valve body using the specific tool (with the tube inflated).
B - Deflate the tube.
C - Fully loosen and remove the valve body and recover the inner locking ring nut through the hole in the tube.
INFLATION VALVE - ASSEMBLY
D - Insert the ring nut in the hole and grip from the outside of the tube to hold it still.
E - Insert the valve body and center it in the anchoring hole. Then push the valve hard by hands and then with the tool.
F - Inflate the tube until it is not cylindrical (the internal pressure must be low). Tighten with the specific tool, then inflate
the tube at the working pressure and tighten the valve one last time.
PRESSURE RELIEF VALVE - DISASSEMBLY
NOTE: THE PRESSURE RELIEF VALVE IS LARGER THAN THE CORRESPONDING HOLE IN THE TUBE. THEREFORE YOU
MUST REMOVE THE INFLATION VALVE AND THEN LET THE BODY OF THE PRESSURE RELIEF VALVE OUT FROM THIS
HOLE.
A - Partially loosen the inflation and pressure relief valves using the specific tools with the tube inflated.
B - Then disassemble the inflation valve and extract it from the hole.
C - Fully loosen the locking ring nut and push the pressure relief valve body to the tube.
D - Recover the pressure relief valve body through the inflation valve hole.
