RE: Substitute for Ether
Andy the lube requirements for a roller big end /little end differ greatly to that required for a bushed end. A fact not recognised by a lot is a bearing can actually run hot if over lubed, this never happens with a bush- ye sounds weared but true.
explanation - a bearing needs room for the oil to pass around the balls/rollers without restriction- restriction causes friction heat.
a bush needs a full coverage of lube to keep the shaft/pin centralised to reduce friction .
