So, I'm looking to drain and refill my gearbox, transfer box and both diffs this weekend.
In another thread Nitemare gave me details of what I need to do but since my Haynes manual is bloody useless for showing me where the drain and fill plugs are I wanted some confirmation tha, what I think is what I'm looking for actually is.
I will be getting the Land Rover Repair Manual which I hear is better but apparently it's on my Chirstmas list and I've been banned from buying it before hand on pain of having conjugal rights withdrawn :S

The front and rear diffs are fairly obvious. They have drain pulgs on the bottom and another plug about 1/3rd of the way up the flatish face of the diff housing.

The first picture below shows (I hope) the transfer box drain and fill points, labeled 1 and 2 respectively. If that is right then the drain plug looks like it needs the worlds largest screwdriver! Any suggestions on the best way to extract that? (I don't have a screwdriver that big or the muscle of popeye to get enough torque on it to turn it if I did).

The second picture is, I believe, the main box drain plug.
The third could be the main box fill plug (I see now why it's such a pain to fill!) though I'm not convinced, but it is about the only likely candidate I can see on the passenger side :S
Are those correct?
If that is the fill plug then it looks a bit high up the box to me (40% ish of the way up? tough to tell from underneath in the dark). Is it right that the main box has a deeper fill level than the other boxes?

Thanks in advance as ever.

Oh, one more thing...
The man in Halfwit...er... Halfords told me which oil to get if I wanted EP90. (picture attached)
Since I trust the man in Halfords about as far as I can physically throw my landy, can someone please confirm, or otherwise, whether he was right?
Thanks :)

yep he was right but yer gonna need atleast 3 litres for the gear/transfer box and 1.75 litres for the diffs each

to get the oil out of them there shold be sunnot that looks like a fookin big flathead screw on the bottom of evrything ( a 3/4" chisel fits the slot perfect and a good plumbers wrench will turn the chisel )

to get the oil back in its any wich way you can but as its a series you could pour the oil all over the top of the diffs and gearbox and itll find its own way in :D:D:D

Yup, as mentioned in my first post I have one of those, seemingly on the transfer box (my gearbox geography is still a little shakey).

The drain on the main gearbox appears to be a normal bolt type.
Drains on the diffs look like square socket holes, as do the fill plugs.
Can I just put my socket wrench in there directly?

So, are the pictures I posted correct?

Just like mine. Pictures seem correct.
I managed to get a wrench in there. Careful not to over tighten plugs after filling - diff pans can be rusted quite thin.
 
you have found the WRONG bolt to undo on the gearbox

the one you want is halfway along the gearbox and awkward to see without a torch, it has a 1/2" square head and is a tapered thread that a gorilla has usually done up too tight :rolleyes: (should just be nipped) so make sure your spanner fits good and tight

the drain bungs on your axles (underneath the diffs), you say you have ones with square sockets in them, then your 1/2" drive ratchet/tommy bar should fit those, if they were the flat slot ones then a piece of 4mm thick steel plate/angle iron can be formed into a key to undo them

i've not looked at either of the guides linked to as i'm supposed to be working :eek:

Thanks for the confirmation. I had kind of come to the conclusion that was likely the case. It just didn't feel right.

Yeah, have one of the slot ones on the bottom of my transfer box. Don't have any steel plate or angle iron so no idea how the hell I'm going to get it off yet.
Any chance a 2p coin in vice grips would be strong enough to do the job?

i doubt it, more likely to twist the coin but you might get lucky

then the question will be, would you be confident of managing to do it back up tight enough using a 2p coin and molegrips ??
 
Fair point, but I'm kind of out of ideas :S
Any suggestions where I can get some 4mm steel plate I can turn into a tool?
Wonder if I can make it with a dremmel :S
 
i suggest going to aldi and buying a set of files, B+Q sell reasonably cheap angle grinders and hacksaws

take a run round one of your local trading estates and look for a fabrication shop, they should let you scrounge a small piece from thier scrap bin

a dremell would do the job but you'll be spending most of the day doing it :pound:
 
For the slotted plugs I've usually found an open ended spanner in the toolbox that will fit in the groove - a few taps on the other end with a hammer and they come off.
 
Is there any way to flush the oil in the diffs?
Without a strip down and rebuild that is.
I've drained the diffs and the crap that's coming out looks like mud :S
Can't help feeling it would be best to flush it a little iff possible.
Any and all suggestions very much appreciated.
 
All sorted.
Used a small cold chisel and an adjustable wrench to remove the transfer box drain plug. The fill plug on it was a pig, but got there in the end.
Thanks for the assistance all.
