I am overhauling my 853 control valve and in trying to order spool seals, came across a reference in the Bobcat parts website to BTI374. It talks about some lip seals no longer being made and using quad ring seals instead. I couldn't find the bulletin via Google so my dealer emailed it to me and I'm putting it here in case others need it.
