littlegadgi Posted January 28, 2015 Report Share Posted January 28, 2015 (edited) hi all sump plug rounded off so cannot undo any ideas how to get off the drain off one underneath Edited January 28, 2015 by littlegadgi Quote Link to comment Share on other sites More sharing options...
jfc Posted January 28, 2015 Report Share Posted January 28, 2015 (edited) You could try a slightly oversized star drive (torx drive) the plug is only aluminium so just tap the drive into the rounded socket and it will undo if your carefull.

littlegadgi Posted January 28, 2015 Author Report Share Posted January 28, 2015 i have ground a larger allen key down but just slips think previous owner over tightened may have to drill and left hand tap out last resort have done oil change via sight glass not ideal then blew out with airline Quote Link to comment Share on other sites More sharing options...
craigrushton Posted January 28, 2015 Report Share Posted January 28, 2015 Try the above with a little heat, its aluminium so a hair dryer will work ! Doesnt take much as its aluminium. Quote Link to comment Share on other sites More sharing options...
craig10 Posted January 28, 2015 Report Share Posted January 28, 2015 Try hammering the head of the sump plug first, that usually crushes the washer slightly and so reduces the load on the threads. A few sharp blows are usually enough. Quote Link to comment Share on other sites More sharing options...
reggie Posted January 28, 2015 Report Share Posted January 28, 2015 I have found the best solution to get an allen bolt with the internal hex has been wrecked is as follows.Take a short length of stranded copper wire AWG 16 or so strip back 3 cm, spread the strands of wire across the internal hex then take your allen wrench and hammer gently into the hex this will tighten things up so you should be able to undo the fastener. 2 Quote Link to comment Share on other sites More sharing options...
steve_earle Posted January 28, 2015 Report Share Posted January 28, 2015 The Torx bit works a treat, especially with alloy, Just be sure to order up a new sump plug to put back in Quote Link to comment Share on other sites More sharing options...
lineaway Posted January 28, 2015 Report Share Posted January 28, 2015 (edited) Take off the skid plate. Use a small chisel and knock it loose. From now on use the right size torx as it grabs better. I have seen quite a few minders carrying torx instead of allen. The torx gets a better bite the first try. PS the oil filler plug can be used until you get the proper parts.

dan williams Posted January 29, 2015 Report Share Posted January 29, 2015 Sounds like they should make them Torx to begin with. Quote Link to comment Share on other sites More sharing options...
lineaway Posted January 29, 2015 Report Share Posted January 29, 2015 Actually Dan, I think torx works better in an allen than in a torx. Try it if you have not. Quote Link to comment Share on other sites More sharing options...
goudrons Posted January 29, 2015 Report Share Posted January 29, 2015 Leave it in place. The glass window in the left hand engine case will unscrew, so you can tip up the bike and drain the gear box oil. Quote Link to comment Share on other sites More sharing options...
