The best ways to Perfectly Align Your Gears and Chain
"What Not To Do !!".
Don't guess !! The most crucial thing is not to simply blindly guess about alignment. Simply since
you successfully mounted your sprockets and properly connected the chain around them does not
imply its "Miller Time." It is {very that you verify that the front sprocket and rear sprocket are
parallel and in the exact same plane with each various other. Failing that, the chain will run at an
angle from the sprocket teeth. The consequences of this misalignment are few and substantial
people realize the
effects of even a small angular divergence.
What Does Misalignment Cost?
Much has actually been discussed, and a lot of people are aware of, the premature wear and
performanceissues connected with the tires on their motor vehicles when they run out of
alignment Great deals of complex equipment exists at the car service center to recognize and
correct misalignment. When it comes to a chain and sprocket gear system, almost nearly has has
actually published released offering owner/mechanic a true
understanding of the value of alignment, much less how to do it. Dyno researches performed back
in the 70's verified significant power losses (approximately 4.75 horse power on a 400cc machine)
with sprocket/chain misalignment of as little as 8.5 degrees. These tests also verified that the
wear rate on the sprockets triples, chain failures on these automobiles increased 35 % and
derailments were two times as likely.
When you think about that an owner might spend $500 or even more on an accessory pipeline
that yields a 3 horsepower rise, it would be madness to give it all back due to the fact that the
drive system was not lined up.
Put simply, it is extremely expensive to neglect exact alignment.
Normal Alignment Techniques.
A lot of people just eyeball the chain alignment as best they can, guess that it's close enough then
forget it. Some think it does not matter at all. Most individuals do not have any concept that a
simple approach exists. All three groups are wrong. (The eyeball men) can give it their best shot
and still often end up from 4 to 10 degrees off, resulting in quantifiable power loss and extreme
wear. The 2nd.
team is ignorant. The 3rd team is uniformed.
One laborious method is determining the distance from the center of the swingarm bolt to the
center of the rear axle on both sides and insuring the measurements are equal. Some difficult
gauges were built with sliding/locking bars and pins to complete this (I made use of and made one
in the early1980's). It is cumbersome to make use of, far from being universal and very time

consuming. Another idea is to make use of a long, strong straight-edge between the two sprocket
faces to find any non-parallelism. This technique is uncomfortable and in some cases impossible
since of physical interferences with various other elements in the way (i.e. swingarm attach
points, levers, rollers, etc.).
The eyeball guys are really on the right track however one crucial element prevents them from
consistent ideal alignment ... a dependable frame of reference. The unaided eye is destined
Perfect Alignment Every Time.
Assistance is here for Group 1 and Group 3 rider/mechanics. Group 2 boneheads need a mindset
first. An elegant option is now available that guarantees perfect chain and sprocket alignment
regularly. This brand-new tool is an alignment gauge that rapidly clamps to the faces of the rear
sprocket in mere seconds. The basic component is definitely parallel to the rear sprocket faces
and extending 90 degrees from it is what I call, for the "eyeball guys," the missing link ... a sight
rod that points along the top row of the chain as it proceeds toward the front sprocket. With this
visual reference line, even a guy with 20/60 vision could recognize any divergence and readjust
the axle blocks to bring the chain into perfect alignment with the gears. ATV guys will have a more
involved problem because any run out will require an assessment or replacement of swing arm or
rear axle carrier bearings, but a minimum of they are cognizant of the issue. Quad Chain
