he laborious process required to remedy wheelend
issues has always been a major challenge
for technicians. Fortunately, manufacturers
have spent the past few decades making wheelends
easier to install, inspect, and service. Now
technology is making its way to the wheel-end,
presenting a potential game-changing advancement
for heavy-duty technicians to make those
tasks even easier.
" We are putting technology right in the hub
so a technician already has a pretty good idea of
what they need to do as soon as they walk up to
that wheel-end, " said Isaac Otto, digital product
manager at ConMet, a manufacturer of wheelends,
hub assemblies, brake drums, rotors, and
other products.
» Understanding the wheel-end system as a
whole lends to more complete maintenance.

Before jumping into the new gadgetry and
sensors associated with these improvements, a
technician ought to understand the wheel-end
system itself. And it's important to recognize this
encompasses more than just the wheel.
" A fleet shouldn't view a wheel-end as just a hub,
spindle, bearings, and seals, " said Rick Domin,
principal training and product support at Timken,
a manufacturer of wheel-end accessories including
hubcaps, hubodometers, and unitized bearing
nut systems. " Tires and brakes are part of the
picture, too, because everything works together.
Bearings affect the seal and the seal affects the
bearings. The entire system affects tire wear. "
And along with the material cost of replacing
tires, the impact on uptime and safety must also
be considered. When it gets down to it, tackling
wheel-end issues using all of the tools at your
disposal will ensure success for the entire fleet.
But to get it right, you have to ask yourself a few
questions.
What type of wheel-end is it?
" Not all wheel-end systems are the same, " said
Charles Use, senior product manager at STEMCO, a
manufacturer of wheel-end and suspension products.
" The number and type of components differ
from system to system. "
