I know why you bother- because yer a jolly good feller. And it helps us all keep this legendary vehicle plentiful
Thanks!
Glad you bothered Mike, I appreciated your tutorial.
Thoughly enjoyed👍
Glad you enjoyed it
Bless you for sharing this information for TH-cam university for decades to come!
You are so welcome!
Friday I am gonnna start to take it out ! Hope it I will get it out . First STEP!!
Gravity is a marvellous thing...
One of your best videos yet! For us non pros seeing how it all fits together makes much more sense.
Brilliant - so well presented and understandable.! Keep it up!
Thanks Mike. Yorkshire ROB
Thank you for a LT230 master class.
Any time!
@@BritannicaRestorations I would love to see a full video like this on a Borg Warner case like my 1992 RRC has.
I have one here, but I am at odds to sell it cheap as it is, as the coupling work fine or spend time and money rebuilding it at a large expense for a limited market
Another really good video cheers. Reckon I'll have to change shaft a gear next year. I managed to drill a hole in the gear for now but burnt out a carbide tool doing it haha. Also I did have a loss of drive recently all the guys in forums suggested total failure of splines, was actually grub screw on selector came loose. So i f anyone's wee gear stick goes limp check that first!
i repost this tube to facebook. cos i think every land rover owner should spent some time to understand his fantastic explaination. u are such a great guy spending alot of your time. thank u so much. i alway follow your tube n u always surprises me. cheers man.
Thanks for sharing!
Great video, thanks.
You are welcome!
Thanks again for the education 😊
Always welcome
Spot on Mike, excellent video! Thanks for taking the effort putting this together for everyone to see. 👍
Glad you enjoyed it!
Great advice! Sadly i did my transferbox about a week ago!
After a loud bang and some oil leaks, i found the thrust washers did the old E-jecto. I put a ashcroft ATB in my transfer box as the center diff housing was damaged. And its alot better than it used to be.
Oh and when the center diff failed i wasnt being stupid, took off from a red light and bang.
Good video started to see the big picture thanks Danny
Glad you enjoyed it
Great explanation, cheers from down under
Glad you enjoyed it
Really like all the tricks you learn out
Thanks!
That was an excellent tutorial
Tomorrow's video will show what I found with the collapsible tube and maybe why these transfer cases leak!
Cheers Mike. Good to see what's inside my LT230. In terms of clonks - yeah got plenty and so has the Land Rover. Bit at a time though.
Very good!
Thank you! Cheers!
That was a great explanation Mike Cheers Cobbaa 🍀
Glad you enjoyed it
great video Mike ;)
Glad you enjoyed it
The input gear rarely wears out on later vehicles. The clunk is almost always worn splines on the front or rear output stub shafts, or bad backlash in the diff, or worn gears in the diff.
I could have done with watching this a couple of weeks ago..... Would perhaps have saved me some expensive trouble
Great video, mines in pieces awaiting reassembly and refitting (higher ratio).
Good luck!
You are the number one man, just finished resleeving my lt230,being a early version l drilled the holes with a masonry drill in the input gear a couple of years ago. I have a Ashcroft ATB diff instead of the one you are showing.
Yes the masonry bit works well, but it is slow!
@@BritannicaRestorations I have pto on mine, will that lube the splines or do I need to drill the gear if so what diameter? I can't fit one of those adapters, cheers Roy.
Hi Greg, what size drill did you use, cheers Roy.
@@royblackburn1163 8mm to 10mm, l sharpened the tip on the grinder. When you start drilling don't stop or it's hard to get going again. Drilled two right through giving it 4 holes. Did this two or more years ago and the input shaft is fine. My transfer is old 1.003 ratio to a lt85 gearbox and 4bd1t Isuzu motor.
@@GregPalmer2 Prevention is better than the cure and cheaper will do it ASAP thanks Roy.
i remember the series transfer cases, you have to drop the gears out under the motor to undo the bolts into the gearbox. a bugger to get that plate in on the centre shaft on the series too,
Yes a redesign was needed!
Interesting video. I have done rather too many gearbox and transfer box changes and I find it easier from the top. I put a piece of 2 x 4 across the two bulkheads and use a ratchet strap to support the weight. A jack can be used to adjust the alignment. You still have a bit of a fight but it is easier.
Thanks for sharing
Just took my transfer case out and noticed some of what looked like copper pieces in the oil, stripped the centre diff and it looks like my thrust shims on the planetary gears have completely disintegrated.
That will be from the centre differential - check the wear on the inside of the centre diff
I drove a defender 90 with appalling backlash in the transmission. I really thought something was about to break
Excellent video!
Greetings from Brazil! Happy first/only owner of a 97' TDi (my father's car) with 220k Km and for some reason a lot of klunking. 100% stock car. Will open the transfer case next week to look what's happening.
Before you get too carried away, check the propshaft Universal joints, the rear drive flanges in the axle (if it is a 110), and the front axle CV joints
You can check the transfer case by removing the round rear cover on the back and see if there is any wear on the gear/output shaft spline
@@BritannicaRestorations You are the best! It's a Disco, but my guess is that it should be the same as a 110. Will do it in January! My mechanic is on holidays now
eheheh
Love to see how the centre diff lock works for off road.
It doesn't! When in LOCK, the planetary pinion gears cannot rotate, effectively negating the action of the third diff - in others words it is the same as any other makers 4x4 when 4x4 is selected. Front and rear drivelines locked together.
Great explaination. Historical question. What transfer case was used in the Bedford MK military truck.
Sorry no idea
Mine is realy lose. That is whay I have one redy fir 2 years now but no time to change them. 😉
Cheers King Mike. 🥃
Oh no!
Hi, I’ve been watching you show for a few months now. Really enjoying and learning quite a few bits. I am getting my Defender 200tdi back on the road. I swapped the LT77 for an Ashcroft R380+stumpy. And ran into a bit of a challenge. All went well, transfer case & gear box went in fine and all gear selections & transfer selections worked well. While checking the brakes etc by rocking back and forth the transfer case locks up when in gear even when the gear box is in neutral. When the transfer case is in neutral all works fine. In neutral it is free. When adding new oil to the transfer case I accidentally mistook a bolt on the side of the case as the filler plug realising the mistake I did it back up. It didn’t seem to connect anything but I am thinking that perhaps it did. In your video when you have the case on the bench you can see the bolt I am referring to. It’s on the input side of the case an has about a 20mm head. I can’t find and reference to it’s purpose or function in any of the manual I have. Could this be my problem? At the moment I am confused and frustrated. You help would be greatly appreciated. I can send you a screenshot of the bolt if that would help. Cheers Dallas.
The bolt is for a temperature sensor - mainly fitted to automatics
When you say locked up, are you sure the diff lock is not engaged?
@@BritannicaRestorations thanks. That was a quick response. I got to the bottom of the issue. 2 of the bolts connecting the transfer case to the gearbox case actually penetrate into the transfer box near some of the gears. It had accidentally used the longer bolts at those points. They were only 5mm longer but that is enough for them to restrict the movement of the gears. So glad I tested the transmission line by rocking the car by hand rather the off the engine. I could have been rather catastrophic error rather than a frustration and a bit of rework. I do really enjoy your show. Cheers Dallas
excellent video mike,whats your thoughts of overfilling the transferbox oil all the way to halfway mark of the plate on earlier transfercases so that the output shaft of the gearbox gets lubricated ? i know its not recommended but would like to hear your thoughts on it.
Too much oil can be as much of a problem as too little!
With the cross drilled input gear or the oil feed plate, I think the issue has now been solved - but it took many years and many expensive gearbox rebuilds to solve the problem!
I am quite surprised LR didn't put a small drilling in the gear itself, so oil would be pushed into the spline like they did on the series boxes
what happens to the transfer case when you go to the inspection and the defender is on the test bench in front of the brakes where does the power of the wheels that are stationary go to
Installing the imput gear with TC in position is not possible on some ratios without dropping the intermediate gear
Hi mate, hope all is well 👍. Cheers, Serg
Mike. Simple explanation with very good tips or tricks for tool turners ! How did the jokers from the Leyland factory calculate a maximum power or torque figure for the LT-230T ? V.
No idea but set up they will handle a lot more power than any Rover engine fitted
Cheers Mike, We are working on a 1993 NAS Defender 110 with the V-8. It came to me with a howl from the rear diff. Classic presentation were it howled with light throttle but not under hard acceleration or de-cell. After replacing the ring and pinion, the howl remains and appears to be coming from the T-Case! Are we looking at bad bearings? This poor thing only indicates 70,000+ miles... George in Nevada
Could be the shims are too slack or tight - could have damaged bearings - there is oil in it right?
@@BritannicaRestorations Oh yes, there is oil in it. We only began servicing it last year and have no idea of how it was treated prior. Looks like a swap-out may be in order.
Interesting and informative as always Mike. Can you answer a question please? Whats is the difference between the Discovery and Defender LT230s? Ive seen somewhere that an overdrive can't be fitted to the Discovery Xfer boxes but I'm puzzled why not..?
I think it is more due to space - there is not much room behind the transfer on a Disco or RR
@@BritannicaRestorations Ah, that would make sense. The implication was that the o/d wouldnt fit to the xfer box but maybe they meant only when fitted to the original vehicle!
Very specific question here’s, have u had a main shaft input gear make any noises in reverse just when loaded, really hoping it isn’t my gearbox, Ik my diff in my transferbox isn’t perfect wondering if the whole box is on its way,
Hard to say - take off the PTO cover and have a look at the splines - any signs of rust/crud build up, and it could be a transmission/transfer rebuild…
Very common problem
What's your opinion on the over drives available for the defenders and how do they actually work?
I think they are overrated, not just an overdrive - have a look at Roamerdrive to see how they work
How do I know which is the correct input gear to order with a 1988 EA vin RRC auto, are they all the same number of teeth ? the splines between the input shaft adapter & the input gear clearly have slop, 2nd time now! It is noticable when selecting reverse, the first time the splines actually stripped & we lost drive altogether, my other car, DA vin which was the input gear donor had the same clunk but only when put into drive ? But this gear & adapter were perfect for a while when used in the EA ?
You have to work on the serial number of the transfer case, not the vehicle's VIN
So with this. Mine does this clunk and does have a quarter of a turn in it... But in diff lock it also has a fair amount. Still centre diff or elsewhere?
Hard to say - but the centre diff can be problematic
Hi Mike, thought I’d change the gearbox oil on my 94 defender 300TDi, (R380) there was red ATF in it (looked like it anyway). Well, I looked up the forums and read that MTF94 was being recommended, so used it, I would definitely say she’s not as smooth going into 2nd (first thing, but after a few minutes, when everything warm, she’s fine). Should I change back to the ATF? WWMD - What would Mike do? :)
I just put some similar MTF oil in my R380 and the only difference I saw was in my bank balance !
@@BritannicaRestorations lol, think I’ll persevere for a while, I’ve also read Difflock Evo1 oil is the dog’s jibbly bits, might try that👍. Still planning to head to TO in October, will bring more Bournville 🍫 , and post from there👍🇮🇪🇨🇦
Sounds great!
I am contemplating fitting a new OEM synchro hub and 2nd gear to an R380 to finally find out what is going on with these gears - Dave Ashcroft seems to think it is the synchro not slowing down - however it is not in all gearboxes - I drove one yesterday with 300,000 km on the original box and the gear change was very smooth
Thank you mike i think i have this problem how do i know transfer box what is it says 34D 286353E does that mean its LT230
From a quick Internet search it appears as a LT230T 34D 1.410 Discovery V8 & 2.0 Mpi.
But E suffix is strange because as far as I'm aware the LT230 suffix only went upto D not E.
Are you sure the last letter is E not B?.
If he can't help it'd be worth contacting Ashcroft Transmissions in the UK
@@R.Sole88109 it is Discovery 2.0 Mpi 1.410 ratio but im not sure 100 % the last letter E or B, i see this letter like E
Was just thinking (can be dangerous) . Does the PTO lubricate the splines on the input shaft? Or will you need the cross drilled gear . BTW who has a Landrover without a PTO right! 🚙 Cab you drill those holes in a drill press?
If you mean the Roverdrive, the input gear comes with the overdrive and the unit uses the LT230 lubrication for overdrive and LT320- highly recommended to fit the high capacity sump with cooling fins as they get very hot!
@@BritannicaRestorations No I am thinking of the PTO for a winch or other stationary machinery. Could it be that the PTO works as that splash pan you show in the beginning of the video and landrover thought that everybody would mount a PTO and therefor didn't care about lubrication of the spline without an PTO, ?
I have only seen one Defender with a PTO hydraulic power-pac on the back of the box, so I cannot say
Video shows LT320🙃 just saying i am awake.
Sorry - typo!
@@BritannicaRestorations We are all only human.
If they whine, which gear(s) is it likely to be? Or all of them?
Hard to say - maybe it is not the gears, but the shimming is out?
@@BritannicaRestorations - Every time I went for a drive, I had this constant whining. No matter what gear I was in (jacket, jeans, boots) I still had this loud whining. Now, even when I pulled over and turned the engine OFF, I _still_ heard this constant whining. Funny thing is, it stopped everytime as soon as the wife got out....
I have a LT230/LT77 in my series. I have to run on difflock all the time as I only have the rear prop connected. The backlash is monumental. I've used it like this for 2 years but its getting worse. Am I right in assuming that its play in the dog gear on the diff-lock selector hub? Would the 2WD conversion cure this?
Not wise to run on just one prop - there used to be a 4x2 conversion but that was years ago - Bearmach used to sell them
@@BritannicaRestorations They still exist. £210 online. Why is it a bad idea to run with one prop? Surely it should make no difference. I should really reinstall it but I have a defender diff in rear so would need to change front as well.
Could a novice rebuild a transfer box ??
Yes - there are a few ways round you not needing special tools
Hi can anyone please tell me what tools I would need to rebuild a landrover r380 gearbox please?? Thanks, Lee
Let me know if this link works
th-cam.com/play/PLkIBI0td6S2vVCrYcLme1sTjXqB4CWI7S.html
Thank you mate that works
What causes an LT230 to make a whining noise mike
Could be many things, but bad bearings or shimming could be a cause
Great tutorial here's a heads up check out nejisaurus pliers trust me they are life changer vampliers are the same but more expensive rounded screws on landrovers come out easy
They look good - I think I will give them a go!
@@BritannicaRestorations they save me so much time with fixings that have been rounded off by numtys I fix motorbikes and landrovers and I have a few different ones
I second that. I converted a not so easily impressed colleague to them. Just be sure to get the biggest pair.
