GENERAL INFORMATION - CONTINUED
4.
To preclude the mechanically curious from opening the HUBODOMETER® case to find out how it works, the following
information regarding its contents is provided:
a.
An independent main shaft to protect it from front (face) damage.
b.
A spring-loaded counterweight to reduce spin.
c.
A brass-on-steel worm gear.
d.
An externally pinioned odometer mechanism using low-friction molded components.
e.
The case is hermetically sealed to prevent moisture from getting in.
5.
The HUBODOMETER® works basically the same as the odometer in a car except that it is not driven or electrical. It is
an independent mechanical device.
6.
There are three basic ways to mount the HUBODOMETER®.
a.
As a single component hubcap with the HUBODOMETER®.
b.
As a mount on to a hubcap.
c.
On a universal mounting bracket that is bolted to the hubcap.
7.
It may be used either “wet” (oil) hubs or “dry” (grease) hubs.
Installation
000109
What if you have to replace a HUBODOMETER®?
a.
If a new HUBODOMETER® is installed, will it read zero miles, and will the original mileage from the old
HUBODOMETER® be lost?
b.
Yes, but there is a way to preclude this problem. When ordering the new HUBODOMETER® from the manufacturer,
request that the mileage be PRE-SET to the mileage registered on the old HUBODOMETER®. There is normally a
nominal fee for this but it is well worth the cost in order to keep a running record of mileage and service intervals,
with no updates or confusion.

CARE OF HUBODOMETER®
000109
CAUTION
•
Do not stand on, kick, or rest things like booths and wheels on HUBODOMETER®. It will survive
all those on off-road ventures but excessive personal involvement may shorten its life.
•
Do not use solvents, thinners, or paints on the HUBODOMETER® face. If reflective glare is a
problem, tape over the face except for the odometer reading so you can check the mileage
as needed.
•
Do not use air or electrical tools when removing or installing it. Use only hand tools. If it slips
when you loosen or tighten the meter lock nut, put a strap wrench around the meter to hold it.
•
Normally only 15 lb-ft (20.3 Nm) of torque (max) are required to secure the locknut - no more.
The HUBODOMETER® will keep accurate track of the mileage on your semitrailer and offer a way to identify when
service is required and document service intervals. It does not need much in the way of service, but it does need to be
somewhat protected against damage.
