Oil levels + photos

[MQ SWB]

I've just bought a 1980 range rover and i am wanting to know a few things in regards to where in location of fill plugs and drain plugs, changing the oil and how much oil in each of the following.
1: gearbox 4 speed
2: transfer/diff lock
3: Front diff
Also I have a maxi drive fitted to the rear diff and how do you drop the oil and fill up again.
I've had a look under and I think I know where the drain plugs and filler plugs are for the g/box and transfer are, the front diff is okay.
Also what oil to use and how much
I know this sounds a little mumbled I apologise for that
any help muchly appreciated

buy a workshop manual....
especially if you plan on working on the rangie yourself

JUST IGNORE THIS RESPONE NOT THINKING WHEN WRITTEN, MOUTH GOING BEFORE BRAIN THINKING.

Landyman didnt mean it like that, just that it really is in your best interest to get a workshop manual as it will help no end with srvicing and problem solving. G/box level is on left side of box about half way up and easiest to fill thru shifter hole, t/case level plug is just below pto cover and filler is under rubber grommet in trans tunnel between fron seats. Diff drains are a pia as they have a flat blade screwdriver slot to undo, fill plugs are in center casting just above pinion centerline on one side. 4spd box - g/box 2.6ltrs, t/case 3.1ltrs, diffs 1.7ltrs .

thanks for that nick, I do intend on getting a manual but Im going bush this weekend and just wanted to make sure all levels are okay before I go as I do have a couple slight drips from g/box and transfer, I don't really want anything to go bang because of lack of maintenance, I know landyman didn't mean it like that but I just wanted a rough idea of where, and how much oil in each. I apologise if I have offended anybody with my remarks, but something like this happened before when i asked my first or second question in the nissan section and the response i got from one of the members really sucked as I had just bought my first real 4wd and was new to the scene I really didn't think i warranted that type of response
once again I do apologise

Many thanks

seeing as i did not see you response all is cool....
as loanrangie said... a workshop manual is the best investment you can make after purchasing any car... i even take mine with me when i go wheeling... you never know when the prince of darkness will strike

The LT95 4sp gearbox and transfer case use engine oil. Do not use EP type oil as it will attack the bronze components in the boxes.

The LT95 4sp gearbox and transfer case use engine oil. Do not use EP type oil as it will attack the bronze components in the boxes.

It is GL5 rated gear oil that will attack the phosphor-bronze bushes and synchros. Some of the low viscosity (pours like water) GL4 gear oils like Castrol VMX80 can be used and may be better for the box than engine oil.

I run VMX80 in my LT85 5-speed which is originally specified to use engine oil. It was recommended by Mal Story who rebuilt the box just before I bought the truck.

Okay here are two photos of the gear box and transfer case
I've marked what I think in red as the drain plug
and on the transfer the fill plug in green
with the gear box i couldn't get a photo of the fill plug due to the
exhaust being in the way but i think it is above and to the right or left which ever way your looking at it
thanks for th info

T-case is right.

Gearbox looks about right too, but It is a while since I have owned an LT95 (and then only for about a month).

[Nick (in the Falklands!)]

Yes, gearbox is correct too.....lower one is drain, with a little plastic mesh filter behind it....

Little drips are useful..(when they stop...you have a problem.. )

[Loanrangie]

Green arrow on t/case is level plug, filler is on top and is accessed thru the large rubber grommet on the trans tunnel between the seats.

I would just like to say thanks to everybody for the help in changing the oil in the transfer and gearbox, didn't get the diffs done, had a couple of surprises though dropped the transfer oil and as soon as i removed the drain plug I knew exactly what oil was in there, bloody gear oil you can tell by the smell it looked clean so i just topped up with 20w50 and will change it after this weekend out, now for the gearbox removed the drain plug and I heard a sound as if something solid had just fallen out, a bloody self tapper so I checked to make sure it was intact and no metal missing also all up about 500ml of oil came out talk about the clowns who did the last service and yes it was gear oil as well . so once again thankyou to everyone for the help

If it has been driven in really cold weather (i.e. a snow trip) with gear oil there is a chance the oil pump drive may be broken.

....I bet there's a lot of LT-95's out there with the wrong oil in...!!

From what I can make out, it is a factory-induced error dating back to the early days of this 'box; (& having read about similar queries within the 101" Club mag) this seems to be something to do with user handbooks that state maintenance intervals & to refill with specified oils, then the quantity....

In the case of the 101", the user handbook quoted all but the 'specified oil'....

All us agricultural types that grew up on slow-rev engines, whining gearboxes, & Series Land Rovers know ya put '90 in a gearbox...
....bloody oath, y'do...!!!

Just like squaddies.....!!

When you transit thru' late Series 3 (Stage 1) & into early 110s & other
(without the book of 'no' words to hand..) ...Its a bit of a wakeup to find
engine oil in a 'box....!!

My main-use 101" went through a bit of this.....ran for about 6 years with
90 in it, no 1st gear & all. Then 2nd started to get 'sticky', & required a
new knack to persuade it to disengage....had all the feel of a Series reverse idler that has hydraulicked its bush out.... When told what to look for, what a difference to that box....& the T-box ran cooler when towing..
(Still perfectly useable too....just the engine thats stopped playing..!!)
