tangent = another belt issue
GlennA   6/28/2012 9:51:22 AM
I bought a cheap elliptical / exercise bicycle.  I didn't know if it would get much use.  And if it did, then I could justify a more expensive unit.  It quickly developed a clunk in the pedals.  I disassembled the covers to inspect the drive, expecting to find the bearings were failing.  The belt had a fixed tensioner, not spring loaded - the pedaling resistance was adjusted by a drum brake unit.  I don't know how they assembled the tensioner - the belt was ridiculously tight.  I had to struggle to unbolt and remove the tensioner - it was at the end of the adjustment for 'looseness'.  After several minutes of pondering I re-routed the belt and re-installed the tensioner.  The belt is now snug vs. piano string tight.  And the clunk is gone.
