How To: Install Your
Reflex V2 Spur Gear Bushing/Bearing
|
|
|
We already knew we had the best Spur gears
in the market available for racing. These were
a little tricky to install to many racers, experts
and beginners alike, so when we set out to re-design
our spurs we wanted to improve on our design in
whichever way we could.
Fistly, we wanted to deal with the spacing issue.
The best way to address this was to figure out
a way to better center the spur and not worry
about anything else. We also wanted to make it
even lighter, in an effort to increase acceleration
even further. Through testing different designs,
we learned a few things on the way, the result
is what the V2 Spur came out to be.

The kit comes with 2 Delrin Bushings,
but it is compatible with any 4x7mm bearing
available, depending on the differential you
are using. The advantage of bushings is lighter
weight. The advantage of ball bearings is that
it lasts longer in between re-builds.
One of the bushings is 2mm, while the other
is 3.3. The 2mm bushing will work most everywhere,
and the 3.3mm wide one is made this wide in
order to allow for it to be sanded down to the
"perfect width" you may need. |

The spur gear is chamfered
on 1 edge, this makes it easier to install your bushing
or bearing with a drop of thin super glue. Since the
material is pure delrin, the CA will not penetrate the
material, but will bond strong enough to hold the bushing
or bearing in place until you want to remove it. |
|
To install properly, use a flat surface
to push the bearing all the way in on the spur, then
run a thin layer of super glue around your bushing
or bearing. Here we are using a Reflex 2.5mm wide
bearing for illustration purpuses.
Now install the spur in your diff and
experience the huge gains from having a true, lightweight
RACING spur gear.

NOTES:
This spur works with most differentials
out there, with minor, if any modifications. The guide
below gives you a starting point for the proper installation
of such.
