My own cut silicone rubber bands will go back in there

Just querying what this refers to? Having recently been through a third
band replacement with my ancient Aiwa FX-90 (part of system rack) and
had to bodge with an undersize band from eBay as originals no longer
available! C+


Places that repair hydraulics have a huge selection of o-rings in
round and square types.

2 troubles with that is its ok slicing a square into 4 say but only 2 of
them
would have a fair face on one side, to go against the drive pulley.
I've tried slicing circular O rings, physically worked but the rubber seems
to be too stiff ,whatever the technical term is , restitution?, lack of
stretch for a given cross section area
