bigyellowthing Posted October 28, 2017 Share Posted October 28, 2017 Hi All Once again I seek your wisdom The threads for my sump bolt are buggered. Anyone got a solution? All advice gratefully accepted Best Quote Link to comment
E T Posted October 29, 2017 Share Posted October 29, 2017 Get a new bolt ! :-p if it's the thread in the sump that's stripped find something longer as its threaded all the way through, a ham fisted mate over tightened his es750 sump I modded a spark plug ( same thread m14x1 ) worked fine Quote Link to comment
micktodd Posted October 29, 2017 Share Posted October 29, 2017 As above or could helicoil it good video here Quote Link to comment
Dezza Posted October 29, 2017 Share Posted October 29, 2017 Remove sump, repair thread, refit sump with new drain plug and aluminium washer (the plugs only cost £3 or so from Suzuki and fit multiple models). Quote Link to comment
Wilf Posted October 29, 2017 Share Posted October 29, 2017 Yeah a helicoil is the way to go Quote Link to comment
neil w Posted October 29, 2017 Share Posted October 29, 2017 Sorry but don't bother with helicoils, Wurth Timesert is the way forward ... did mine 20 years ago and it is still fine 2 Quote Link to comment
RUSSP Posted October 29, 2017 Share Posted October 29, 2017 You can get a spark plug thread repair inset which is the same thread I used one on mine and it has been fine Quote Link to comment

Used in the aerospace industry for nearly all threaded holes in aluminium. 1 Quote Link to comment

Wilf Posted November 4, 2017 Share Posted November 4, 2017 Or just find a slightly larger sump plug an tap it out to suit. No drama Quote Link to comment
bigyellowthing Posted November 5, 2017 Author Share Posted November 5, 2017 Once again Old Skool is best. Due to the design of the sump drain will drill and tap to next size. The casting has slots to allow oil drainage which would be blocked by inserts like helicoils and I'm a bit paranoid about plug failure leading to expensive and depressing consideration of parts prices..

Slot or not - makes no difference to oil draining, Its a big hole and oil comes out - end of story! A helicoil will see out the life of the bike unless you are a gorilla with the spanners! 1 Quote Link to comment

bigyellowthing Posted November 11, 2017 Author Share Posted November 11, 2017 Does anyone have the tightening sequence for sump bolts? Quote Link to comment
Gixer1460 Posted November 11, 2017 Share Posted November 11, 2017 Alternate and diagonal - not critical, just don't over-tighten! Quote Link to comment
bigyellowthing Posted November 11, 2017 Author Share Posted November 11, 2017 Wow that was quick. Thanks for the info! Quote Link to comment
