My current theory is that the Magna engineers will have specified ‘proper’ bearings for their transfer box but then their procurement people found some nice cheap ones from Slovakia, and these are not up to the task. This theory is based on a sample of one and I may well be proved wrong on this! I still find it interesting that Magna have chosen to axially preload this input bearing (with two disc springs/Belleville washers) - makes you wonder if they saw issues with this bearing during development?

The two halves of the casing come apart easily. The Land Rover dealers are ‘allowed’ to do this as it’s a necessity for the replacement of the front & rear driveshaft flange seals. There’s no paper gasket for the joint face – just sealant.

I’ve never tried removing one of these transfer boxes myself. From the workshop manual it appears pretty straightforward but it looks as though the top four bolts are a pain to access and Land Rover recommend a special tool (wrench adaptor) :

Mine was also weeping from the seal, all repaired by lr under warranty.

Interesting write up Phil.  There is nothing that can't be fixed with a hammer😜😜

An excellent write up Phil.

Once you have successfully rebuilt it you can have mine for a strip down

Very interesting, informative write up Phil. I really like to read this one and ZF 6HP26 write ups.

I have changed these simple shaft bearings couple months ago and I would like guys to know in future that 6210 C3 from ZKL is specially designed for this transfer box as this bearing with C3 has special inner bearing egde cut.

When i found this bearing failed and saw ZKL i though that replace with SKF is much better and bought set of all four bearings (if I remember 6209 6210 6211 6212) from SKF but then realised that SKF inner ring does not have that cut edge and can not fit to its place so I went to other local bearing specialist and was lucky to find out that they will deliver that C3 bearing in one day.

Phil you're top mate

I have the same transfer case with a stretched chain (like the old ones).

Trying to find a chain. Any suggestions?

I believe that Cobra Transmission (Miami) stock the chains

Hi phil,

Having to have my transfer box sealed for the 3rd time, as it keeps leaking from the silicone gasket!

Any idea what the best gasket silicone is, as i will get some and throw it in the direction of the dealership....

They just dont seem to be able to get it right and it fails after a few months. Not sure what they might be dong wrong apart from not using enough silicone, not letting it sit for a few mins before mating the faces or torquing it immediately, as opposed to letting it set up for an hour fingertight/5lbft.

Any ideas methods for making this a good seal would be gratefully received. Im half thinking of getting a refubished one to give them to fit! There is nothing that can't be fixed with a hammer😜😜

I'm on my third seal too - mine turned out to be a crack in the casing.

Give me a callt

Hi Phil.

have you heard of porosity in the casing? Or even a crack?

I have a re-occuring oil leak issue?

bump

Yes I have, though I’m struggling to find the information again. It may have been from a Discovery or RR Sport bulletin board because they use the same transfer box. I definitely recall seeing photos of cracked/porous transfer box casings and they’d been like that since new. I’ll see if I can find it again.
