The Range Rover never suffered from the �split drum� issue as, by 2002, ZF were fitting the stiffened A-clutch drum to all 5HP24s

Thanks for that - at least it puts my mind at rest with regard to the fail safe issue!  Tym

If it sticks, force it. If it breaks, it needs replacing anyway.

Mine failed, I took the motor off, removed the potentiometer, took the cover off, gave it a good cleaning with some IPA and switch clearer and then put it all back together. A pretty easy job to do, you don't even have to jack the car up to do it. Certainly worth a go before spending any money on it.

Browsing through RAVE this evening (as you do!) I noticed a section for replacing the "fuse" for the Transfer Box, which is located in the engine compartment below the Transfer Box ECU. From the circuit diagram this is a 50 amp jobby. Could this have anything to do with it not switching from low to high ?

(Shot in the dark as guessing if it is happy to move from high to low, the power must be there?) .

Thanks Joe - now it's in high range I'm loathed to try this as I don't want it stuck in low again!

I'm intrigued by the suggestion to clean the potentiometer with Indian Pale Ale... Tym

Sorry for link to another forum I was just just too lazy...
So here we go with proper post:

Today I opened potentiometer and found the source of the problem. There are holes in the graphite layer, right under the sliders of the potentiometer. Holes are in the High range position, where transfer box is most of the time. Beside that it moves just a bit every time engine starts, so sliders just rub against graphite surface and "eat" it.

rather than linking to another forum , can you post your solution here... ... - .- -.

sorry, had posted the link, my english was not able to read the rules.... , but the Information in this link is old and well known...., it is to clean the poti. L405 SDV8 2017 + Lancia Flavia Coupe 1964 + RRS L494 3.0 SDV6 + C220CDI Convertible 2021

It is not enough to clean the potentiometer as it is not really dirty. You have to modify sliding pins in the potentiometer. If you look the picture you will see where is a problem ( and sollution )

not being mechanically minded can you arrow the 5 sliders on the picture that need bending as looking at the picture i have no idea.

On this pictuere you can see sliders,

Thanks, not sure if im willing to try as can be a little heavy handed dont want to break anything!

You should try and get a few, repair and sell I would be willing to try one

I suspect I may have this problem. Has anyone tried something like this to repair the track:

If anyone has a broken motor/potentiometer they don't need I'll happily give it a try and document for the forum.

Hi Gang,

Same problem so I used Povh's technique (slightly bended the connectors outwards) and it all works fine now.

It took 2 to 3 hours all in, but well worth it considering the price of the whole replacement unit.

Note that I only took the motor's outer plate off (6 screws) and then the potentiometer itself (one circlip off then unplug it).

The longest part it to open and close it properly (I used a dremel and a soldering iron)

All fitted back and work 100% (for now...)

Cheers for sharing this great trick Povh! l=Oo\________/oO=l l:OolΞΞΞΞΞΞΞloO:l
