if we crapped out a gauge we just replaced it with a new or used.. what ever works. Its not like the military changes oil on a time or millage thing... they send in a sample and have it tested to see if the oil needs to be changed. we did not change one trucks oil in 2 years.... just kept adding.
So really any gauge can NEVER be trusted.
i concur. since we've gone to AOAP system (
years ago) we don't track hours. the AOAP report provides the direction on when an engine needs replaced. the motor pool still tracks mileage on dispatches, but it doesn't affect maintenance intervals.
the only thing that affects the maintenance intervals is the service catagory that it is coded in the ULLS-G box; if it's in a 'limited service' code (don't remember which code), then it lets you do [maintenance] services half as often (annual).
the ULLS-G box tells the unit when the truck is due for annual or semi-annual maintenance, and that's just based on time. every month you have the clerk run the services report to let you know which vehicles (and support equipment) will be coming up for services. if you don't do the service within the month it's due, then ULLS-G automatically reports the vehicle deadlined so that it cannot be dispatched.
so when a guage is swapped out, the mileage is updated in the ULLS-G box. for no reason, really, but it's done.
