Help With Override Intake Chain Tension

Hello,

Our current intake used to feature a tighter chain loop but we found out it bends the axle, so our new chain has slack.

We know we need a chain tensioner but we don’t know how to build one.

When the intake spins inwards to bring the pin and cup in, there is slack on the top of the chain,

and when it spins outwards, the slack is at the bottom.

How do we build a chain tensioner that can tension the slack wherever it is on either side or the chain?

Thank you very much!

screw joint a spacer and then put the chain on it.

also u shld use nylock nuts instead of keps nuts for everything

and screw joint ur wheels
