Drewmotty Posted June 10, 2019 Report Share Posted June 10, 2019 Does anybody know what this boss is for on the bottom of an A Type overdrive casing? Quote Link to post Share on other sites
RogerH Posted June 10, 2019 Report Share Posted June 10, 2019 Hi Andrew, that is easily knocked off - be careful. There are a few small oil ways inside there and that small lump probably gives them room for manoeuver Roger Quote Link to post Share on other sites
John L Posted June 10, 2019 Report Share Posted June 10, 2019 It was probably a cast stub to locate the casing in the jig for drilling all the holes. Perhaps?? John Quote Link to post Share on other sites
RogerH Posted June 10, 2019 Report Share Posted June 10, 2019 About three years ago I knocked that lump off in trying to dismantle the OD. I was trying to be helpful. The company doing the rebuild scrapped the casting. Roger Quote Link to post Share on other sites
