The best ways to Perfectly Align Your Sprockets and Chain
"Exactly what Not To Do !!".
Do not guess !! The most vital thing is not to simply thoughtlessly guess about alignment. Simply
due to the fact that you efficiently mounted your gears and correctly connected the chain around
them does not
suggest its "Miller Time." It is {essential that you verify that the front sprocket and rear sprocket
are parallel and in the same plane with each various other. Falling short that, the chain will run off
at an angle from the sprocket teeth. The consequences of this misalignment are substantial and
few people realize the
ramifications of even a small angular divergence.
What Does Misalignment Cost?
Much has been discussed, and a lot of people know, the premature wear and efficiencywhen they
are out of alignment, problems connected with the tires on their automobiles. Great deals of
complex equipment exists at the auto service center to correct and identify misalignment. When it
comes to a chain and sprocket drive system, almost practically has been published released the
owner/mechanic a true
understanding of the importance of alignment, much less how to do it. Dyno studies did back in
the 70's verified considerable power losses (approximately 4.75 horsepower on a 400cc device)
with sprocket/chain misalignment of as little as 8.5 degrees. These tests likewise validated that
the wear rate on the gears triples, chain failures on these motor vehicles went up 35 % and
derailments were two times as likely.
When you think about that an owner might invest $500 or even more on an accessory pipe that
yields a 3 horsepower boost, it would be insanity to offer everything back because the drive
system was not aligned.
Basically, it is really costly to overlook accurate alignment.
Typical Alignment Techniques.
A lot of people simply eyeball the chain alignment as fine as they can, guess that it's close
sufficient and afterwards
forget it. Some think it doesn't matter at all. Many people don't have any concept that an easy
approach exists. All 3 teams are wrong. (The eyeball men) can give it their finest shot and still
often wind up from 4 to 10 degrees off, resulting in quantifiable power loss and excessive wear.
The second.
team is ignorant. The third team is uniformed.
One laborious approach 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 pins and bars to accomplish this (I developed and made use
of one in the very early1980's). It is cumbersome to use, far from being universal and very time
consuming. An additional idea is to utilize a long, solid straight-edge in between the two sprocket
faces to find any non-parallelism. This Due to the fact that of physical disturbances with various
other, technique is awkward and in some cases impossibleparts in the way (i.e. swingarm affix
points, levers, rollers, etc.).
The eyeball men are actually on the right track however one crucial aspect prevents them from
getting.
constant perfect alignment ... a trustworthy frame of reference. The unaided eye is doomed to
guesswork.
Perfect Alignment Each time.
Aid is here for Group 1 and Group 3 rider/mechanics. Group 2 boneheads need a mindset
adjustment
initially. A classy option is now offered that assurances perfect chain and sprocket alignment
consistently. This new device is an alignment gauge that quickly clamps to the faces of the rear
sprocket in mere seconds. The basic fixture is absolutely 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 pole
that points along the top row of the chain as it proceeds towards the front sprocket. With this
visual reference line, even a man with 20/60 vision can recognize any divergence and readjust
the axle blocks to bring the chain into perfect alignment with the sprockets. ATV men will have a
more involved issue because any run out will need an assessment or replacement of swing arm
or rear axle carrier bearings, however a minimum of they are cognizant of the problem.
