Ahhh....don't you just love having this "time bomb" between the gearbox and transfer box
Always knowing it's there, but never knowing when it's going to  up your day!
Hope you get it sorted soon.  80" 80" 86" 88" 90"
Wanted, Forward Control Anything considered. |

I would certainly like to get hold of the knob who decided that the splines on that shaft didn't need greasing on assembly
It will have to wait till Monday so I can phone around some places. Anyone know how heavy the LT230 transfer box is - just wondering about the ease of doing it on the drive. |

Transfer Box is easy enough to remove albeit heavy. Easily enough though with two, I wouldn't attempt it on your own, extension housing isn't a problem either. The shaft is held in by a circlip. But on mine the coupling was a right bar steward to get off. Had it come off easily then it's a good morning's work.
 I started with nothing and still have most of it left!Last edited by Rickydodah on 11th Jul 2015 9:02pm. Edited 1 time in total |

It would be worth fitting a modified adaptor, this allows oil to lunricate the shaft and prevents this problem from happening again. The name of the company escapes me now, a very well known company though, especially for gearboxes.

Ashcroft is the company you are thinking of. TBH I'm not completely convinced that their solution is optimal, although the cover that is part of the kit will certainly stop the shaft moving backwards as has happened on some of the failures that have been seen.

What i dont get about the reports of the shaft moving out of the spline is the plastic cap that fits over is held by a cable tie and the cap has tags on the end that fit over the back of the outer splined cup , no one i far as i know has said there cap was broken , so how has spline moved ?
also the oil seal in the transfer box polishes a ring on the adaptor seal , only ever seen 1 ring for the shaft to of moved there would be 2 polished rings also the area on the adaptor shaft is quite short where the seal rubs , if it moved wouldnt it then damage the seal as the rest of the shaft isnt machined to have a seal run on it |

About 70 - 80kg and not that well balanced either to handle, easy enough to crush you! |

The transfer box is very easy to remove with the aid of a transmission jack if you're working solo on your drive. To remove the coupling, the special tool (to hold the 'socket' attached to the main gearbox) is a real bonus. You are also likely to need a slide hammer (to get the shaft out of the socket) and a decent puller (get the socket off the gearbox).

Due to lack of time (and a transmission jack) it will probably be going to a local indie to be sorted. I'm now planning to get the clutch replaced at the same time as its starting to chatter with the gearbox in neutral.
Could have been worse - like half way up the A1 with the tin tent in tow. |

Mr Horseman, I also live in Suffolk. Where are you planning to have this job done and do you know the likely cost please? I too have a chatter in neutral for a couple of minutes when cold and I'm also thinking that a new shaft would take out a bit of slack so it's something I will consider having done.

The chatter in neutral is unrelated to the adaptor shaft - its due to the springs in the clutch wearing, eventually it will sound as though there is a bag of spanners being shaken under the vehicle. If its only a light chatter I wouldn't worry about it yet.
If the adaptor shaft splines are worn it will introduce some slack in the transmission. The greatest problem is there is very little warning before they let go (I managed about 3 miles). Not sure which garage I will use yet although will probably be one near Cambridge (very unlikely to be Marshalls due to their eye watering about rates). |

It might be worth taking it too a dealer as the Landrover rep on here said that the coupling should be greased from factory so Landrover should (in theory) foot the bill if no grease!

don't think any were greased from the factory
think the greasing was part of the tech bulletin on replacement of the shaft |
