How to Program your Hubodometer

Program you hubodometer to your tire size that is available from the above links.

The how to program the hubodometer sheet is available for download and printing by clicking this – link.


We recommend using a piece of wood and a hammer to install Hubodometer. The timber should cover the entire device, so the hammer load is even on all points when tapping it into position.

Note: It is essential Locktite is applied when hubodometers are inserted into hubs to help prevent them becoming dislodged during transit. Some hub bosses can vary by as much 0.2mm. This variation in some manufacturers hub sizes can cause a loose fitting bearing buddy. We recommend a medium strength locking compound on all bearing buddies and Hubodometers.

The Loctite applied on the fitment surfaces will help prevent the Hubodometer from dislodgement from branches and rocks in extreme offroad conditions.

Log Book

A good start for your logbook would be

  • 500 miles after taking delivery.

Hubodometers installed on RV’s and other rigs trigger a service level for manufacturers.

Warranty issues are easier to understand when accurate kilometre reads are available.

The manufacturer’s checklist will incorporate some of the items below, however, this same list is a good start for the DIY brigade, with older rigs.

1. Bearing check.
2. Tyres wear check.
3. Electric brakes and/or disc pads check.
4. U-Bolt check.
5. Shackle bolts, bushes and shackle plates check.
6. Gas lines.
7. Coupling tightness.
8. Wheel nuts for tightness.

RV’s or campers or Trailers that are used for work or hire purposes will need the mileage recorded if your accountant is like mine. Otherwise, they may be assessed as a pleasure item.
