graeme Posted May 1, 2016 Report Share Posted May 1, 2016 If you have a multi tool set and have ever wondered what the T47 Torx driver bit is used for, I have a solution. If you need to remove the small 3/8" plugs that hold the detent springs in the gear selector casing, then the T47 is perfect. Tap the driver bit into the plug and then turn the bit with a spanner and the plug will come out and the best bit the plug is reusable as they are currently NLA.

BlueTR3A-5EKT Posted May 1, 2016 Report Share Posted May 1, 2016 (edited) Slightly off at at tangent here..... Are we sure the plugs are 3/8" and not 10 mm? 3/8 is 9.52 mm Maybe the 9.5 mm plug would do? http://www.southwalesprops.co.uk/propshaft/consumables/core_plugs_cup_metric.htm I have never measured one - any one out there with NOS item and a measuring stick? What is the size of the casing counterbore precisely? Graeme - Try a 3/8" and a 10 mm or 9.5 mm twist drill shank in the hole for comparison. and let us know please. http://www.coreplugs.co.uk/index.php?route=product/product&product_id=99 And do we know what these are? http://www.burtonpower.com/cam-carrier-core-plug-3-8-ford-bda-bdg-fb555.html Peter W Edited May 1, 2016 by BlueTR3A-5EKT Quote Link to post Share on other sites
RogerH Posted May 3, 2016 Report Share Posted May 3, 2016 (edited) Hi Pete/Graeme, Simon Winter (on the forum) got some off ebay late last year. I'm sure he said they were 10mm. http://www.tr-register.co.uk/forums/index.php?/topic/55304-gearbox-top-cover-plugs/?hl=%2Bgearbox+%2Bplugs http://www.tr-register.co.uk/forums/index.php?/topic/50613-gearbox-detent-plugs/?hl=%2Bgearbox+%2Bplugs Roger Edited May 3, 2016 by RogerH Quote Link to post Share on other sites
RogerH Posted May 3, 2016 Report Share Posted May 3, 2016 Hi Folks, the above give a couple of ways to make a screw thread plug. However it is easily possible to 'metal spin', on a lathe, caps that should fit A simple mandrel to make the internal shape. A spinning tail centre to hold the metal against the mandrel And some thin(ish) 22swg or thinnner to form. Always use a brass spoon to form the steel. Roger Quote Link to post Share on other sites
simonjrwinter Posted May 3, 2016 Report Share Posted May 3, 2016 Yep, 10mm core plugs fitted a treat Quote Link to post Share on other sites
graeme Posted May 4, 2016 Author Report Share Posted May 4, 2016 Yep, 10mm core plugs fitted a treat Thanks Simon, If that is the case why do the usual suppliers not use them. They are invariably listed as NLA. Cheers Graeme Quote Link to post Share on other sites
