It's a slightly different issue on the Tdci setup. The MT82 gearbox had an extension housing fitted to the back of it to allow it to bolt up to the LT230 transfer box. This necessitated an extension shaft that takes the drive from the MT82 output shaft and delivers it to the input gear of the LT230. An awful bodge at best, but that's not the main issue. Unfortunately it seems that some Land Rovers either didn't receive any/enough lubrication at the joint between the MT82 output shaft and this extension shaft (which is a dry splined joint, not oil-immersed like a sensible person would have done) or the shaft was installed incorrectly leading to premature wear - hence these failures. |

some mis alignment hmmm. what was misaligned and how was it rectified. having had the shaft replaced myself and the gearbox a month or so later and now 6k miles down the road I'm sure things are going down hill. I can't understand why the shaft, 3 oil seals and then the gearbox would go along with issues with the hand brake if there wasn't something a miss. together with the vibration at 1750rpm ?? I'm fully of the belief there's something not right for the shaft and gbox to go - as much as I'd like to think I've been unlucky I'm sure something aint right ? talking of misalignment is there any ajustment ? I thought the engine, bell housing, gearbox, extension and tranfer box all bolted together without any adjustment - how could someone check if they're aligned or not? |

I did wonder how it could be misaligned, and I can't see how you can tell from the outside.
However, lookng at the two parts (I've got them at home), I wonder if one end of the adaptor shaft may not be fully inserted into the large ring (I'm not sure what the correct term is - it's part 3 in the image from Pete on your earlier thread www.defender2.net/forum/topic17193-15.html ) that it fits into. The wear on the splines on the large end of the adaptor shaft, and the corresponding wear on part 3, seems to suggest this. If is isn't fully inserted, I guess this could possibly lead to excessive loading, and hence wear, on the splines? Note that this is my best guess and it could have nothing at all to do with it! |

again my best guess.....
once the cases are bolted together how could anything not be fully inserted? |

I agree you would think that it should all fit together as designed. I didn't replace mine myself and so can only go off the comments from the garage and the wear pattern I can see on the failed parts.
Maybe it's a combination of bad luck and poor design? But then again, how come many (presumably most) Puma Defenders don't have any problems with the shaft? Do they use the same parts in the 2.2 Puma? Anyway, mine seems okay now - there's a lot less slack in the transmission, one less rattle, and there's still no oil leaks! |

hmmm
should have a def back tomorrow after they've fitted a replacement transfer box sump plug and replacement drivers door actuator. and then they're gonna test drive it so it'll be interesting to see what that reveals.....absolutely nothing I suspect 
tell me why would could this happen. rolling along at c 3-5mph and you wanna pull away. so long as I'm not pulling anything heavy or going up hill I'll use 2nd. so you'd expect a little clutching slipping and off you go. only no - kangaroo city. a bit like the clutch saying you stink and you're not coming anywhere near me... then after 3 or 4 attempts the clutch engages and all is good. I'm not talking about straining the engine and it vibrating like its trying to stall. I'm talking about the transmission jumping up and down. not a bag of spanners sounds but more smooth but as if all the transmission fixings have been removed ?? |

My 110 started to make "clunk" noises day before yesterday, when accelerating, and shifting gears; yesterday drove it to the mechanic, at 40km/h, and got there but did not move any more! Had to be pushed inside!
First diagnostic: transfer box failure...will know more today...
Can you tell me exactly what is the adaptor shaft (pic? microcat diagram?) My 110DC has now 49000km only!

Have a look here for a microcat diagram. The parts which fail are 3 and 22. You may want to look at the whole of the thread, which was I think the first reported case of this failure.
If this link doesn't work look at Page 6 of this thread. You may also want to read this thread. Editted for spelling. |

You can see some pics of the damage here, it's apublic album, from my friend who's dismateling it
https://www.facebook.com/media/set/?set=a....amp;type=1 and this one more close  Click image to enlarge everything with rust and dry as desert sand I'll post some pics of the new vs. old next monday Regards Joao '10 Land Rover Defender 110 CC '08 BMW F800GS '64 SIIA Forward Control '69 SIIA 109 ZA CKD _____________________________________________ You have the right to remain silent.

I learned today from a senior tech at a main dealer that there is now an official mod consisting of reworked parts to address this problem. The internally-splined cup which attaches to the gearbox output spigot now has two diametrically-opposite grease nipples, and the extension casing has a hole in the bottom directly beneath the nipples. The idea is that by turning the output shaft until the nipples are vertical and inserting a greasegun through the hole, the assembly can be greased. Low-tech but probably effective.
I don't know how recent this is, so perhaps someone with a recent 2.2 could look underneath and see if their vehicle is so fitted. Also I don't know the part numbers involved, perhaps someone can advise? |

Customer of mine had his 2010 , 20k miles 90 towed to my workshop, his gearbox output shaft had stripped, we fitted a ashcroft recon box for him- 20k miles...............
that's pants!! |

This may sound daft, but it looks like its most common on 110's?
Anyone know if 90's are prone to it too? Wil |

what about just drilling hole in the extension case and use spray grease ( a good sort of chain lube type of stuff) possible it might help also looking at the picture is there a gap at the top by the lever gaitor maybe that could be used to get some kind of grease in there |
