TPM-40
SENSOR for HOLLOW SPOKE WHEELS:
TPM-40
sensors are specifically for the wheel-spoke mounted tire valves. They do not have a fill-port,
so adding or removing air requires them to be taken off – just like a valve cap.
Installing TPM-40 sensors requires them to
be fully threaded-in on the tire valve to
provide secure sealing.
Remove the existing valve cap and
inspect the threads and check to see that
the valve core is flush and not protruding.
X
Begin threading the sensor on the tire
valve.
Y
As you keep threading it, you may hear
a slight hiss, as a small amount of air
escapes before it is the sealed.
If you felt that it was hard to thread it for the last couple of turns, or you need at
least a ½ more turn to seal it up; remove the sensor and use the 4-Way tool to
chase and clean the threads of the valve-stem.
You can repair minor scratches or a slight
damage to the threads of the tire valve.
Use the 4-Way tool to chase the entire length of
the threads by twisting ½ turn then backing off
each time – use thread lubricant or tapping fluid.
Seat the valve-core – finger-tighten only.
Check for any air leaks - use soapy water and look for air bubbles.
TPM-40 sensors add about
¼ oz (10 grams) to the
wheel, which is within
limits of a typical wheel
balance.
Do not remove valve-core
if you do not have air
compressor available to
re-inflate the tire.
