How do I change clock readings?
New vehicle clocks and odometers
A manual adjustment to the Difference field may be required when an hour clock or odometer has been changed in the vehicle. This can be done in TTC through a tyre change or vehicle period end.
EXAMPLE
The hour clock's last recorded reading in TTC is 52,006. The clock was removed from the vehicle at 52,050 and when a reading was done on the new clock, it read 115. The
Difference
is determined by adding the usage on the old clock to the usage on the new clock ->
52,050 - 52,006 = 46 + 115 = 159
. The
Vehicle Hours clock would be
115,
and the
Difference
should be manually set at
159.
NOTE:
If the clock was nonoperational for a period of time, it may be more appropriate to set the difference by calculating how many days since the last activity and multiplying that by the average daily usage. i.e. 126 days @ 17 hours per day = 2142. Statistics and estimated clock/odometer readings are displayed at the bottom of the first tyre change window to make the math easy for you!
See a odometer rolled back to zero in Vehicle Period End.
