Basil Fawlty Posted July 23, 2015 Report Share Posted July 23, 2015 I have a slight crunch when selecting 3rd gear 1500 with J type overdrive the problem does not appear to get any worse and otherwise the gearbox is fine, Cardiff to Triumphfest the other week no problem. Can any of you gearbox wizards point me in the right direction Is it a possible home fix ie synchro ring or a selector issue? Plan B is a gearbox out so also looking for a good overdrive box or longer output shaft to swap in a Spit 1500 or Midget box All offers suggestions gratefully received Baz Link to comment Share on other sites More sharing options...
Darren Groves Posted July 23, 2015 Report Share Posted July 23, 2015 Probably worn synchro ring. Give Mike Papworth a call, he can talk you through options: 024 76644499/07 Link to comment Share on other sites More sharing options...
Pete Lewis Posted July 24, 2015 Report Share Posted July 24, 2015 yes many things control how sychromesh works the baulk ring has to grip the cone on the gear the dog teeth on the gear and sleeve must be a nice defined chamfer any chimbled edges will allow the baulking action to release the sleeve needs 3 good springs inside and a clearing clutch action. worst with it being 3rd you may have a failed mainshaft spigot and bearing worn out ,a very common problem .
