LOF MT82 Upgraded Adapter Shaft

Just seen this on social media. A different approach to the Ashcroft one.

Interesting.

If, as has been surmised here on several occasions, a main part of the problem is misalignment between the MT82 mainshaft and the LT23 input shaft, I would think that all that that would achieve is that the splines on the end of the mainshaft fail.

It also would appear not to be secured to the back of the mainshaft, so I don't on the face of it see what inhibits axial movement.

On the plus side, I see that it has a lifetime warranty. Provided that also covers destruction of the mainshaft by the adaptor, the warranty could be the winner.

It will be very interesting to see some long term reviews in due course.

It looks sort of ok , having had one land rover that had 3 under warranty and 2 versions of the Ashcroft over 108,000 miles, will LOF be able to test it for long enough to give piece of mind
My current works motor is on its original at 117,000 miles , but feel either a slave cylinder or clutch will force me to replace 2014 2.2 90 hard top , Warm M8000 , Scorpain winch bumper, Ashcroft rear atb

Think I will stick with my Ashcroft kit in mine.
On the subject of lifetime warranty, once it fails it has come to the end of its life surely

Hold my beer and watch this!

It’s being tested in his DefStang which is running considerably more power and torque than any 2.4/2.2 can deliver. If the quality is anything like the rest of his products I have no doubts in its longevity. 2011 Defender DCPU 2.2 - https://www.defender2.net/forum/topic30623.html

I have his original Ultraspec kevlar clutch from when LOF was working with Shabs at Syncro Gearboxes and I would guesstimate I've done 50k+ hard miles on it so far and its still a perfect bite featherlight clutch pedal

so going by his quality Id buy it if I had to replace my shaft which is a well lubed modified LR one fitted 75k miles ago. 2008 Santorini Black 110 XS USW (Sold)

I asked some questions regarding the new Upgrade Adapter Shaft.

Here is the info directly from LOF;

It will not damage the main shaft as it’s a driven fit onto the splines, it then torques down with the draw bolt.

The end of the shaft is also ground so it seats perfectly flush against the inner race of the gearbox support bearing.

As for an alignment issue, the casings are all dowelled and machined so the adapter casing is true to the transfer box (providing no one has take dowels out)

Hope that clears up some questions.

That is very interesting. Clearly it has a centre bolt down the middle, which is unexpected, but I don't share LOF's confidence in the alignment of the extension and transfer box. It certainly should be true, but if it was it is unlikely that there would be so much variability in the life of the LR parts.

There is a picture showing the centre bolt plus some other parts I can't identify on their "instagram" page:-

Interesting indeed! It certainly looks the part...

I'd try one but having just fitted the latest genuine LR one and only doing 6k a year I wouldn't be much help

I’ve just bought one from LOF along with a clutch and other bits and bobs. I should get it fitted in a couple of weeks and will report back as to how it looks and feels.

As for now, not one single Ashcroft shaft failed. Correct me if I'm wrong.
They've been selling them for 5 yrs

If the misalignement theory was correct, we should have been reported at least one failed Ashcroft shaft ...

^^ I've certainly not heard of any failure of the Ashcroft part (although that doesn't mean there haven't been any but does suggest that at worst they are very infrequent), but I don't accept that that rules out alignment.

The immediate cause of the standard ones failing is fretting of the splined coupling, which indicates relative movement of the parts. The only two obvious causes of fretting are (a) that the coupling is not properly assembled (not fully engaged) and there are many photos of failed one where clearly the male part has not been fully engaged in the female part, and the spring ring has not held them together, or (b) that the the gearbox and transfer box are not correctly aligned, so that every revolution of the intermediate shaft results in some movement and hence wear of the splines. Both of these cases but especially the second are likely to be improved by decent lubrication, so it is entirely possible, I believe, that with an Ashcroft shaft there can be some misalignment but still a healthy life expectancy of the coupling.

If there is no misalignment, how would you explain the fact that you can have two identical vehicles off the line, assembled from identical parts in an identical manner, with an identical lack of any lubrication, yet one coupling fails at under 30k miles and the other fails at over 250k miles? There must be some other factor at play, and my preferred theory, at least until replaced by a better one, is that there is an accumulation of engineering tolerances through the extension housing that can, at the "wrong" extreme, misalign the coupling sufficiently to cause greatly accelerated wear.

Please accept that my knowledge of these things, and these specific parts, is limited. But if the MT-82 mounting surface and the transmission box mounting surface are true, are unadulterated, are as per made in their respective factories, and if no shim or spacer has been added during fitting, how can the gearbox and transmission box be out of alignment? One assumes (here’s my gap in knowledge) that both will have been made with flat faces, 90 degrees to their overall shape/design, for flush fitting? If this is the case, where/how does the misalignment come from? I understand that Defender parts (indeed LR parts) may not be made with the tolerances demanded by NASA. Monsieur Le Grenadier

I've not been everywhere, but it's on my list.....
