When using WCP Cams to maintain chain tension on an axel with a clamping bearing block on either side, is it necessary for both bearing blocks to have their own cam or is only necessary per axel? The primary concern I have is whether the axel will remain perpendicular to the chassis with only one cam, but I'm not sure how founded this is.
One cam is fine. Once you cam the bearing block over, tighten the blocks back down. This keeps the shaft from bending and makes it straight as the blocks are tight against the tube.
Awesome, thanks for the help!
