There will come a time when a vehicles hour meter fails and needs to be replaced.  TMaSS allows the replacement of an unlimited number of hour meters through the ‘Edit Vehicle’ function.  When you edit a vehicle, you will see the ‘Replace Hour Meter’ button .  


Edit Vehicle Dialogue


To replace hour meter, tap the  button and fill out the following on the ‘Replace Hour meter’ dialogue.


  • Date the hour meter was replaced
  • The current hours of the hour meter being replaced (or the faulty hour meter)
  • The current hours of the new hour meter being installed.


When the hour meter is replaced, the current hour meter reading on all dialogues that display this field will show the new hour meter reading.  This removes any issues with field staff confusion when entering hour meter reading in the future. 



When add a new hour meter, TMaSS keeps a running total of the total hours for the vehicle and its associated assemblies regardless of how many meters have been installed.
