I wound it in all the way by hand and only put the torque wrench on it when it was all the way in. It went in nice and easy. Came out nice and easy when I started too though once i'd cracked the seal.
I suspect it was buggered from the beginning and had been wedged/glued/stuck in somehow for one last time without the previous maintainer fixing it at the time thinking "oh, that'll do - i'm selling it soon anyway".
Anyway... it's all fixed now (temporarily). "50 pence", who lives quite near me, came over to lend a hand, so thanks a lot Del!
Before Del turned up though, I thought I had sheared off the bolt and left most of it inside the hole, but when we tried to drill it the drill bit didn't even make a mark. Upon closer inspection of the sheared bolt we realised it hadn't sheared at all... it had come out completely and just left the magnet wedged in the hole.
The only option was to hit the magnet through to the inside of the transfer box, take the inspection cover off and obtain the magnet.
Needless to say, the magnet had gone right in the corner behind the largest cog, but we eventually managed to grab it.
All we then did was retap the hole to M12 right the way through (only the bottom of the hole was threaded originally), stick a piece of M12 threaded bar in there, keeping it away from the main cog, of course, and then put a nut & washer on the end of it to keep it tight.
I then put the inspection cover back on after cleaning the faces and filled it up with oil!
A few pics so you all know it did happen!!
The nut that we thought had sheared off, but had simply left its magnet inside the hole.
You can see something stuck up there in this one... including lots of bits of metal!
All done (at last)! The transfer box oil renewal took over 3 hours though!
So... in summary...
- EP90 stinks. It really does smell awful.
- The £10 Draper oil suction pump I bought is useless. It managed to put almost as much oil on the ground and myself as it did into the transfer box, and the seal inside it is so bad it takes 4 or 5 goes to fill it up properly because it lets so much air in. This also means, of course, that it lets a lot of oil out when pushing it into the transfer box, which then goes all over yourself and the floor.
- Although the transfer box is kinda fixed (as long as it doesn't seep oil over the next few days) it'll need heli-coiling properly by a garage at some point soon, which will mean draining and refilling the transfer box oil again! The garage can do it this time though.
Oh, and I'm only half way through the service now... I did the engine oil, oil filter, fuel filter and transfer box oil, but I still have the diffs and the auto gearbox fluid to do and the rest of the greasing and other service items.
