Meszaro's Motorsports Axle Nut
(written by ranger400ex)
After a year of riding and racing the rear bearings of my EX
required the dreaded bearing change. While in the process I
decided to get rid of the sub-par stock axle nut and go with
an aftermarket. I had used a couple different brands on my R
over the years and didn't seem to have much luck with one lasting
for more than a couple rides without loosing or popping over
the ring. I had seen a plug on Exriders by Bob owner of Meszaro's
Motorsports regarding his axle nut. I talked with Bob and he
assured me that his product was superior to those I had tried,
it was a better price and that I would not be disappointed.
I ordered the nut and it arrived two days later by brown (UPS).
The nut came nicely packaged, two pieces (aluminum nut with
double nut bolts, stainless ring holder) along with instructions
for installation.
The installation was very straightforward
and only took about 30 minutes. Remove the right side wheel
and the hub. Remove the stock axle nut if not already removed.
To remove stock axle nut. Take a large wrench, adjustable, or
pipe wrench and loosen the skinny nut by turning it counter-clockwise
(facing right side) towards back of quad. It will take some
elbow grease, as the stock nut is loc-tited on. After the skinny
nut is loose turn the large nut counter-clockwise until the
snap ring on the axle is exposed. Remove the clip, then turn
both nuts until they are completely off of the threaded collar
(clock-wise). Throw the stock axle nut in the trash or keep
it as a memento.
Clean the threads on the axle good and make sure nothing is
in the threads. Install and thread the Meszaro's nut onto the
threads with the stainless ring facing out. Thread it counter-clockwise
until the clip area is exposed and then reinstall the clip.
Turn the nut clock-wise until the ring is covered up and butted
against the stainless ring in the nut. Tighten with two hands
and make sure there is no play in the axle assembly. If everything
is ok tighten the two bolts on the nut snug until it clamps
down on the threads. The double nuts assure that you cannot
strip the bolts because the nut is not threaded; threaded aluminum
is bad (Another great design idea from Bob). Reinstall the hub
and wheel and take it out for a ride. Check the nut after a
couple rounds and adjust if needed. I have raced and trail ridden
the nut about for a while now it has held up well. It is still
tight and has not slipped over the axle ring. I think the days
of constantly checking the axle nut for problems are gone thanks
to Bob from Meszaro's Motorsports and the MeszNut. Also check
