Roy Batty Posted April 29, 2007 Share Posted April 29, 2007 Howdy Folks: New guy here and of course with a large problem 1986 exMOD LR90 LT77 gearbox - Discovered why the 90 was marking its territory so - extension case drain plug ( with screen ) threads are stripped inside the case Anyone come across this before ? As I will have to drop the gearbox / transfer box anyway - seperate the transfer so I can repair all the gaskets there - should not be too difficult to have the extension case helicoil'd - anyone know what size ? Or know of a better solution ? cheers thanks Quote Link to comment Share on other sites More sharing options...
Mo Murphy Posted April 29, 2007 Share Posted April 29, 2007 I'm familiar with that awful sinking feeling I repaired mine with chemical metal and it been fine the last six months. Helicoil woud be the repair of choice if you're dismantling the gearbox/ transfer assembly. No idea of the thread size though, sorry.

freeagent Posted April 29, 2007 Share Posted April 29, 2007 had the same problem with my sump.. wound the drain plug back in and it just kept rotating... I di the same repaired it with chemical metal before recutting the thread. I then used a difflock.com drainplug which has a valve built into it, and never needs to be removed. considerable less hassle than removing the sump.

Roy Batty Posted April 29, 2007 Author Share Posted April 29, 2007 Howdy freeagent: Cheers thanks for the note - Ya chemical metal would maybe work if I just want to set the plug - but this drain plug has a screen , etc.... good suggestion thought - I will set the bolt till I can get a retap/ helicoil Cheers thanks Quote Link to comment Share on other sites More sharing options...
