<DIV><SPAN class=693435315-02032019><FONT size=2 face=Arial>There have been many
discussions on this forum about which modern engine oils and gear oils
would be equivalent to the lubricants specified in the AH Manuals. The original
lubricants are generally not available. I have attached a chart that
shows an easy way to cross over from engine oils to gears oils and the
relative differences in viscosity. Remember to only use a gear oil with a GL-4
rating.</FONT></SPAN></DIV>
