A bit sarf of Dorking
Just become the proud owner of a 110 19J/LT77/230T. Actually, I've been given it. Result.

Result? Well in a way. I was given it because I broke it - or more accurately it broke while I was driving it.

Large volume noise from transfer box, nursed it homeward for a few miles, then no drive. Front propshaft drive on transfer box is sticking out by about 5mm and it's obvious that this is why no drive. Engage diff lock and drive home gently. No tight corners etc, assuming that the front drive may be re-connecting from time to time and not wanting to do more damage. Occasional jumps out of diff lock.

Take front prop shaft off so that I can still use it while deciding what to do. Encourage by threads on here to say that diff lock jumping is probably due to lack of use/need for WD40.

Today, unfortunately, it jumped out of diff lock for the very last time. Cannot get drive at all. Just won't engage, no matter what combination of events I use. Also notice that I don't need to follow any of the *figure of 8" route on the tx box gate. I can go diagonally if I want.

So. I'm looking at the legs kit for the transfer box (and gearbox too - very noisy in 4th 5th). And wondering.

Here's where you lot come in.

What had given up to allow the front shaft drive to move 5mm forwards and disconnect? (Nut's tight, can pull it out or push it back in) And what (almost certainly connected) has done the diff lock in? Am I likely to find a broken output shaft?

And has anyone rebuilt a transfer box. How hard? (to a bloke who was more than a bit handy on jap bike gearboxes with the benefit of a horizontally split design?

Ta chaps.

I ant done a transfer box but have done a gearbox, an reckon if yer even thinking of having a go yerself then you'll be able to sort it it's just a matter of downloading the manual off here if you can find it and making the odd tool. If yer can put a bike gear box back together then you'll **** a landy transfer box.
 
Grunt, thanks for that compliment. But it may not be enough.

The the thing that worries me is that the front output shaft is not connected to what it should be. That can only be because a) the shaft is broken, or b) it's disconnected for some other good reason.

If it's is broken, the damage to the casing might be terminal. (or £400 for a recon). If it isn't, then the legs kit might save my car, life and everything.

As an aside, jap bike gearboxes are a doddle, the shafts just sit there and look at you. You can do all the end floats without closing the box.

Harumph. Why aren't they all like this?
 
Know wot you mean about Jap gear boxes, owld Triumph ones int so easy yer need fingers seven inches long. But honestly the LT77 gearbox is easy enough if you have the tools an the place, having had a look at the transfer box while doing the gearbox reckon it's easier. Do a search on here for the manual an have a look.
 
Bit of a bump. Sorry.

Gearboxes coming off tomorrow / Thursday. But would like to reduce the pain, in advance.

My assumption is that because the front propshaft drive has emerged from the Tx box, that the crown gear on the end of it is dead. Because it was possible to get 100 miles out of it with the front propshaft off before the diff lock on I can't think of any other explanation.

First symptom = Lots of noise

Second = noise and odd feeling through the wheel

Third = less noise (oh goody, it's fixed itself)

Fourth. No forward propulsion. Drive home in diff lock having peeked underneath and seen propshaft drive emerging from Tx box.

Remove front propshaft and continue to use for 20 miles. Now no drive. Diff lock refuses to engage. The digital figure of 8 pattern on the knob does not equate. I can move the lever from Low no Diff lock to High + Diff lock diagonally.

Do I bother even opening up the Tx box?
 
It could be that it was just getting nackerderer an the drive was lost to the front prop an putting it in difflock transfered all the drive to the rear prop. have you got any pics of the front output shaft emerging from the transfer box, could it still be the front diff?
 
Well. It's coming off tomorrow, regardless.

Whether I bother having inside a look is debatable.

If the crown gear is mainly absent, I imagine that any casing mounted bearing is also 'lunched', fecked etc...

Trying to get a handle on how bad the contents might be. One needs a certain amount of optimism before the spanners are wielded.
 
If yer take the cover plate, front output housing off an the difflock selector housing off you can see pretty much everything that might be fooked. Dunno wot ebay ones are going for as whether it's worth repairing even if the cases are OK.
 
If yer don't mend it an you've got an understanding Doris, then you could take the guts out of it, clean the whole thing up, mount the brake drum end on a solid bit of timber a bit of Beech or Oak or summat an get a bit of glass with holes drilled in it to suit the front output shaft holes an hey presto you've got a bespoke telly stand.
 
I think that I need to make my position clear. I don't have any ambition to drive the 110 to the top of Goat Fell (the only mountain that I've walked). I don't drive my kids to school in Chelsea.

I've been (very generously) given the landy, and wish, at the age of 50+ that I'd driven one at 20. My life would have sorted itself.

But. I've driven and owned 'performance' cars, with their 'flappy paddle' gearboxes (which are brilliant). The last, an Alfa Romeo 156 2.0 ss s/w was fantastic. I've still got it.

But. I love sailing, and would compare landy driving to that. It's not the time taken from A to B, it's the journey that makes life worthwhile.

Central to that is that it works perfectly. You're going to laugh here. I want the gearboxes to be quiet.

Chassis is fine. Props and half shafts are next in line for assault. Body is a bit rubbish, but I have a plan,
 
hi boguing

I dont know where you are based but if you find your transfer box is dead and you are local i have a good transfer box. It could do with a new input gear bit of back lash couple of output seals pence, but otherwise good i swapped it for a higher ratio box from a discovery after an engine conversion i dont want mega money something around 50 quid would be good Jai

Think you just about summed up the majority of people on here. I dint do the cars bit but had bikes instead never saw the attraction of cars. Part of the attraction of Older Landies for me is the fact that they are so easy to work on including the transfer box. An the more work I do to mine the more I enjoy driving it.
 
I'm in Dorking, Surrey, and would certainly be interested.

Hello again,

I'm based in Luton Bedfordshire.

As for the rebuild on the discovery channel that was done by ashcroft transmissions about 10 mins walk away from my house, its not very detailed, LT77s require 'special tools' that need to be made or purchased from landrover, transfer boxes are quite simple. I have the DVD of the 4x4 was born worth a watch wouldn't say its great though. Jai
 
OK. Big day for boxes removal is Tuesday.

But....

I have:-

LR official Series III manual (free to a good home) which gives good strip/rebuild words and drawings.

Haynes Series II, IIA & III - which gives superb X sections, exploded views. You couldn't ask for more.

And Haynes 90, 110 & Defender (up to 56 registration) Diesel. Which tells me that I'm an idiot and shouldn't even think about looking inside a gearbox.

I've also downloaded the .pdfs on the dl section. Great, but no drawings.

Does anyone have a drawing (X section and/or exploded of the LT239T box?

I want to analyse the problem before I get dirty.
