It was probably the cheapest way that the Ford MT82 gearbox could be adapted for use with a 4wd transfer case. Darren

It sounds better if you call them Mustang boxes, rather than Transit!
It is of course because it is a standard, multi-application gearbox designed to fit many vehicles, and this is the chosen method for mating it with the LT230. It isn't the method that is the problem, it is the implementation of the method. This method has been used in countless vehicles over the years without problems. |

Not that I know anything but i'm inclined to agree hence you've got 200k out of yours.
In terms of implementation what's the difference between a good en and a bad en? |

Lubrication. Clearly, some got it and others didn't when the two boxes were bolted together at the factory. Darren

Sorry mate more to it than that. My last one was lubricated and it only lasted about 25k miles. When it came out I looked as though it had never been lubed so I suspect there many on here thinking they have not lubed their shaft but in actual fact were lubed up initially

Hi Caterham, good to see you are still here , what shaft and what clutch are you running now and are you still happy with the IRB map DEFENDER 90 TDCI XS,
I hope everyone is well and your land rovers make you happy |

likewise.....which makes me think a meet up is probably long overdue
stilling running the clutch from IRB which I believe is still available albeit from a supplier under another name. can't quite recall how many miles without checking but seem to recall it was swapped at about 52k miles. 40k miles later and there appears to be discernable difference from new. I'm on my 4th intermediate shaft (original LR) - not sure what if any alternatives there are out there? This one had the blue 'gue' that was used on the last run out models so it'll be interesting to so how successful the blue gue is? in terms of the re-map......well I'm still having intermittent issues but can't see how that can possibly be anything to do with the remap as they've been there from day one. and it so happens the def has been pretty much perfect for the last couple of weeks and ironically I'm booked in at long last for a new gearbox, upgraded transfer box and rear diff - possibly new intermediate shaft and clutch while we're at it along with slave cylinder and most importantly and new damper valve
but back to the remap, other than it perhaps being a little too sensitive on the throttle pedal sometimes ie going slow on bumpy ground can sometime be interesting - but I'm not convinced this isn't as much down to my intermittent issue as it is sensitive throttle pedal. Ignoring that the map / engine are going an absolute treat - it actually seems to be getting better with time. to be honest I really can't recommend it enough - on fuel savings alone based on the standard set up it's worth doing. I've also now got a straight through centre pipe which has given it a bearly noticeable but improved sound track and seems to have helped just a little with the breathing. you're very welcome to have a test drive if you're seriously considering it yourself. |

Wayne
thanks for feed back, my clutch was replaced along with the shaft by LR at 11k miles under warranty , at 20k miles (now) the clutch is noticeably rattling (easily discernible in the garage less so normally) and some play has come back in the transmission. I am saving up for the Ashcroft replacement lubricated shaft which I will probably fit myself. I might also go for the clutchfix clutch which is sold by some other defender upgrade companies but will have to pay someone to fit it as I dont have the time/space or equipment. I keep considering a remap but want to get these weak links sorted first and quite frankly my engine has always run really well especially since the airbox mod and centre silencer removal. Keep smiling and all the best Rob DEFENDER 90 TDCI XS, I hope everyone is well and your land rovers make you happy |

I'm thinking that the intermediate shaft and clutch should be done at the same time?
doing the mileage you do there's probably little to be gained by getting an extra 10% on fuel economy. the air box mod you refer to I presume this is removal of the impeller? I think the Truckfix clutch is now Clutchfix? Once I get the work done next week I'm off to Spain and very much hoping to enjoy the driving and it not be incredibly frustrating like it was last time with mechanics not playing the game

Quick question: can anything be done to prolong the life of the output shaft, or is there any way to see it's state from the outside?
Also, gearbox needs to come out for changing this, right? I sometimes have the clonks, when I am not changing gears with the approbiate care. 90k miles on the clock. |

Ashcroft do an upgraded shaft that allows lubrication from the gearbox.
You need to remove the transfer box to replace the adaptor shaft, but the actual gearbox can stay in situ. |

As I understand it there has never been a failure of the Ashcroft component.
Obviously Ashcroft claim to have designed this component to solve the lack of lubrication, but do they also claim to manufacture a stronger product? I'm just wondering how much of this is lack of lubrication and how much is an inferior original part. |

Hi Leviathan,
Reading the blurb on the Ashcroft site, it sounds to me as if they use the standard LR parts as the start point, adapting both the female & male components as part of the modification. From their website. We take a new LR030054 and spark erode two small slits in the front face where it fits to a bearing, also remove two teeth from the front spline at 180 degrees to eachother, then spark erode another two small slits on the rear face under the clamping bolt, this now allows oil to 'leak' out of the mainbox to this spline. We also turn a thread on the outside diameter and also make two O ring grooves. The TUD500020 has a ground diameter that the transfer case input seals runs on, we take a new part and regrind it to run this diameter further up towards the gearbox. If/when mine lets go I think I would spend the money on the Ashcroft solution as dragging the transfer box out without a ramp is something I wouldn't want to be doing too often! |

Ahh thanks for that Lohr500.
So the suppersition is that the lack of lube causes the splines to wear and the resulting play causes a 'snatching' shock torque load and breaks the shaft? If so its something I've just realised! |
