honestly, the lack of research and the poor quality of facts that get presented in this place sometimes....

when you strip the thread you back of 1/4 of a turn, you back of half a turn after it breaks.


in one of the appendixes for the series manual there should be a look up chart that gives default torques for various bolt sizes

[ame="http://www.boltmasters.com.au/webfiles/boltmastersau/files/boltmasters_pty_ltd_recommended_assembly_torques.p df"]This is a very comprehensive list from bolt masters[/ame]

theres lots of other out there on the internet but remember to use the correct chart for the bolt type...

in a series you can be facing

metric (fine standard and course thread)
imperial (UNC, UNF,)
witworth (BSF and BSW)
BS Conduit
BS Pipe
BS Pipe, tapered
BS electrical
PBMRWFW (Previous Butcher Maintainers Random Whatever Fitted Works) and
UNSRHGL (UNknown Stripped and Rounded Head, Good luck)

Yes, all of them can legitimately be on the engine. and NO, BS does not stand for the expletive you use when you proclaim "THIS IS ..."after you work out what you thought should have been one type of fixing isnt and your spanner doesnt fit properly, it means British Standard..

I suggest a good set of one size fits all spanners. (no, no I do not, that was sarcasm, SARCASM people If I hear of you doing that expect to be doubley accused of needing the blue and white apron firstly for not knowing which thread you were up against and second for resorting to the hack tools)

You left out BA (British Association) and sometimes even RLT.

So cups are out, is the threaded plug at the back a normal thread, can't shift it at the moment and just wanted to check it wasn't a reversed thread (can't see why it would be).

The one on the real left of the engine block, that resembles the small bung out of an old 44 gallon drum! It was for the "arctic heater" that could be fitted on vehicles sent to extremely cold climates.
It is right hand thread but may need some encouraging words to help shift it!
Good Luck!
Cheers, Mick.

you're going to resort to every trick in the book to get that one then when you hit the end of the book you're going to start thinking outside the square.

Ive drilled and dremeled and filed and hammerd and heated and oxied and die grinded,cut at, chiseled, pin punched generally abused with very very very big hammers drilled to size and then picked the remnents out with a scribe then cut new threads and then I've come across some properly hard to get out ones.

take your current definition of "Indescribably difficult" and be prepared to have it redefined.

you're more likely to get a 4 page center spread article published in 4wd action proclaiming that, no you dont really need to have suspension lifts, big tires, lockers, the worlds most expensive air compressor, or anything to much more than a stock series to have a good time on a cape trip.

Maybe I should just leave it in and not replace it, don't think it actually leaks...
