Chain Tension
Chain tension must be carefully considered so that the
loads created on the components will not be too
powerful. The sprockets and chains consist of 3 drives.
See Figure 3-7.
• The 1st drive is spring loaded. Adjust the chain
between the front roller and transmission to have
approximately 2" of total deflection.
• The 2nd drive chain adjusts up and down. To adjust
the chain, loosen the idler axle bolt and adjust to
obtain about 1/8" - 1/ 4" of deflection. Re-tighten axle
bolt. Be careful not to over tighten.
• To adjust the 3rd drive chain, loosen the 3/4" Hex bolt
and adjust to obtain just enough sag so that the upper
and lower chain strands do not touch each other.
Re-tighten axle bolt.
IMPORTANT
Do not overtighten this chain or the bearing on the 26
tooth sprocket will be overloaded.
NOTES
Leave a small amount of slack, just so the two strands do
not touch each other.
