Outer Limits 4x4 Board

hey guys just need a hand on an issue, both of my filler plugs for the lux, gearbox and transfer will not budge, stripped the heads, heated with oxy, tried to welld another head with better grip what can i do???

heat with oxy should get it.

you want to heat only the plug, not the transfercase aswell.

you could also try hitting it, not too hard as to fracture the alloy housing, but hard enough that it loosenes itself in the threead, failing that, weld a nut to the back of it, and try a big rattle gun.

Heating the tcase should allow that metal to expand more than the plug and break the seal(especially since it is alloy). Heating the plug will only make the therad bind more. A couple of decent sized bangs to the plug with a centerpunch may also loosen the grip further while the surrounding tcase is hot.

Other option which would end up in considerably more work, would be to drill and Ezi-Out the plug, or drill out the plug to within an inch of its life, then carefully cutting down to the thread with a round diamond blade. Both of these options are only viable if you are prepared to open up the case to remove the filings.

I thought this was a medical question and the answer was to RELAX THE ???????

get a single hex socket and try that failing get a pair or vise grips the proper brand and use them to undo them

I striped both gearbox bungs on my Subaru WRX STi... they are some odd gas thread thing... Anyway, I used a speed wrench and they came straight out. If you don't know a speed wrench is a little like a small pipe wrench in that the harder you turn, the tighter it grips. Worked a treat!

thanke for the feed back guys, took me close to 2hours for 2 bungs with a fuck of cold chisel
