lindatr4 Posted May 13 Report Share Posted May 13 Looking to replace the drain plug on the gearbox with a magnetic type and a few questions have arisen. Am I correct in that the threads need to be tapered? Is the drain plug and filler plug interchangeable? I have found the cheapest plug to be this one https://www.overdrive-repairs.co.uk/product/magnetic-oil-drain-plug/ Quote Link to post Share on other sites

I was half tempted to fit a washer of some description but then found it would not tighten fully because of the taper. Quote Link to post Share on other sites
BlueTR3A-5EKT Posted June 4 Report Share Posted June 4 My magnetic gearbox drain plug is taper thread and has no sealing washer. The gearbox screw in fill and drain plugs have the same thread and are interchangeable The big brass plug that covers the filter and magnet in the overdrive has a fibre sealing washer.

That stops the chance of excess stray tape dropping into the gearbox. https://www.wickes.co.uk/LA-CO-Slic-Tite-Heavy-Duty-Pipe-Thread-Compound-Sealant-with-PTFE---240ml/p/227184 Quote Link to post Share on other sites

ianc Posted June 10 Report Share Posted June 10 If a socket set with 1/2" drive is available, select a 19/32" socket and pack it with tissue onto the wrench, then use the 1/2" square end of the socket to remove/tighten the plug in the gearbox, sump, or axle. Crude, but it works ! Ian Cornish Quote Link to post Share on other sites
john weedon Posted June 20 Report Share Posted June 20 I happen to have the right snap on socket for undoing the plug I managed to buy 2by mistake! I could bring it to Malvern if anyone is interested regards John Weedon Quote Link to post Share on other sites

Andy Moltu Posted June 24 Report Share Posted June 24 Too many of these get over tightened and need a hex welding on them to get them off (unless you have the square socket) Personally I use prefer PTFE tape on the threads- helps the sealing as well as making it easier to remove next time. It needs to be tight enough but not gorilla tight. You simply don’t need the torque generated by a silver back hanging by one arm. Quote Link to post Share on other sites

PodOne Posted June 25 Report Share Posted June 25 I know a lot of folk use a hex socket for these square drain plugs and I’ve searched in the past for a uk source for square 3/8 or 1/2 inch socket to fit various drain plug sizes but they seem almost unobtainable anyone have a UK source?

Andy ^ Like this Andy. Two 3/8" sockets back to back, drew their swords and shot each other. In this case the bolt had a chewed up thread and so the nut locks onto, but otherwise a tack of weld or strong loctite on its thread will do it. The plug in the above happens to be for the the differential level/filler, which once the square post is cleaned up takes the same 3/8" drive as the gearbox plug. That locked up nut n' bolt 'adapter' is small enough to permanently live in the toolbox. Like Bob and others I use PTFE tape wrapped around the plug's tapered thread.

Lebro Posted June 26 Report Share Posted June 26 I will probably weld two old, worn out sockets together to achieve the same. Bob Quote Link to post Share on other sites

peejay4A Posted June 26 Report Share Posted June 26 (edited) A 7/16in 8 point socket does the job nicely. Listed here... https://www.uktools.com/716-inch-38drive-8-point-26mm-long-double-square-soc.html Edited June 26 by peejay4A Quote Link to post Share on other sites
PodOne Posted June 26 Report Share Posted June 26 Ingenious ideas gentlemen but given the zillions of drain plugs out there surely there’s a market for a proper sockets which grip the flats to stop folk rounding them off. I’m sure it would save a lot of skint knuckles and pain going forward! Andy Quote Link to post Share on other sites
Bfg Posted June 26 Report Share Posted June 26 There are spanners out there ..I have several of different sizes .. which include drum brake adjusters, and well as the drain plugs. They resemble a ring spanner but with 4-points (square holes) rather than 6 or 12 point. perhaps search for those instead. Melco used to make similar but I seem to recall mine are vintage Gordon Tools https://www.ebay.co.uk/itm/186509837092?itmmeta=01J1B9TVZEYY13YAH91Y879NYW&hash=item2b6cda4324%3Ag%3AbIAAAOSwIhBmddN-&itmprp=enc%3AAQAJAAAA0OIu%2FTS4kikwuqEwI6HjK7uH%2BFdh39l0TMlr8z%2F3KDlc2hDYlD1x1aQqvgD%2BeKsgmKp8N66eSZVXZ5cmy7W1gTovjItyt4ljuvWf8zSpUx0WT%2FFUkyaS9xdlOVV5tIGVNbqZbNWSxBFRGZ0TudAoKe%2BQkQxcgqq7PiEfXbxcnhEs1pKgD2qZQMaa91P40rjzaIkinoBQH6228gaHirnVgxGJ8ZS0XfJrv7nrLHQm7n7dQZiyKAWByiCtZInOwJCzjdLZWYPx070ocFYrT362vuM%3D%7Ctkp%3ABk9SR-q_6-mKZA&LH_ItemCondition=4 Quote Link to post Share on other sites
