DRIVE CHAIN ADJUSTMENT,
CONCENTRIC
SWINGARM
CAUTION: Never adjust or operate the vehicle
with the rear drive chain too loose or too tight as
severe damage to the transmission and drive
components can result.
Break-In: Itisextremelyimportanttomaintainproper
chain tension to ensure the best possible chain life.
Thereis a chain break-in period of approximately100
miles or two (2) tanks of fuel. During this time chain
tension should be watched very closely and loads to
the chain should be kept light.
Checking Deflection: Inspect chain deflection by
slowly moving the ATV forwardso any slack that may
have previously been on the under part of the chain
is now on the top side of the chain. The bottom part
of the chain should be taught during inspection.
Measure the chain deflection as shown in the
diagram. Deflection should be approximately 3/8
in. (10 mm). After inspection, again slowly move the
ATV forward until all the chain slack is on the top side
of the chain and inspect the deflection. Repeat this
procedure several times to check different spots on
the chain.
The chain is correctly adjusted when the tightest
portionofthechainitselfhasapproximately3/8in.,(10
mm) ofdeflection. It’ sacommoncharacteristicofany
chain to have one or more tight spots in the chain.
Therefore, it is extremely important to check chain
deflection in several areas of the chain to ensure
deflection is correct at the tightest point.
