Daan Posted May 25, 2011 Share Posted May 25, 2011 Hi there, I am hitting a bit of a brick wall at the mo; I have a set of kam r&ps fitted to my car. Now I am fitting one of niges diff flanges and a new seal, I come back to an old problem, being the M22 nuts. The pignion has a hole for a splitpin, which I want to utilize. So I need an m22 fine castle nut. The one that KAM suggests is LR partno. 90608545. I ordered these, and they turn out to be ordinary locknuts (with a squashed end to provide the locking action). A quick phonecall to KAM confirmed that this is what they use. I really dont like to realy on these, and previously, I bought a large nut and just drilled a holes through it in roughly the right position (I know) to fit a splitpin. Does a landrover part exist for a castle nut? I did find these: http://www.fullermetric.com/products/nut/din935hex_castle_nut.html but not sure the castelation is in the right position, or whether they have stock. Anyone else any good suggestions? Daan Quote Link to comment Share on other sites More sharing options...

A quick phonecall to KAM confirmed that this is what they use. that will be a nyloc nut then, quite safe as a alternative. not sure what size but 110 up to 1986 parts book show this as a front axle diff pinion castle nut part number 3259 see photo below Quote Link to comment Share on other sites More sharing options...
Daan Posted May 26, 2011 Author Share Posted May 26, 2011 Ralph, that is the imperial, much smaller nut which is used on the earlier diffs. I really dont fancy a nyloc for this application, as a castle nut with a splitpin would allow me to sleep at night, having seen the effects of this nut coming loose. I cant be the only one with this question, surely? Daan Quote Link to comment Share on other sites More sharing options...
western Posted May 26, 2011 Share Posted May 26, 2011 other than the nyloc nut you already have, the castle nut above is all that's listed for 90/110. engineering fastener supplier should have a suitable nut in stock Quote Link to comment Share on other sites More sharing options...

western Posted May 27, 2011 Share Posted May 27, 2011 good point, can anyone check? I dont have an a frame, so I cant do that. daan rear suspension A frame ball joint nut is 20mm according to Microcat NTC4618 see picture below, don't think it's big enough for your requirement.

Hybrid_From_Hell Posted May 28, 2011 Share Posted May 28, 2011 Daan I am sure I have a nut castle type you can have for free amongst the diff stuff I have, but yes Steve used a locknut and thread lock on all the buolds he did. I'll have a peak tomm and let you know - if I have yours free Nige Quote Link to comment Share on other sites More sharing options...
Daan Posted June 6, 2011 Author Share Posted June 6, 2011 Right, I have now gone round the houses, bought a few which turned out an inch or so too long and found several suppliers who wanted to sell me a box of 200 nuts (of the wrong type anyway), I have now located the correct one: http://www.kramp.com/shop/action/SimpleSearch?storeId=60&langId=-1&level=0&searchType=STARTSWITH&query=9372215 It is a shallow castle nut m22 x 1.5, and it fits like it was made for it. I payd about 16 quid for 4 of these, ordered through my local kramp dealer (importer wouldn't sell direct), but this dealer is walking distance from where I live. The correct shallow version turned out to be almost unobtanium, but this lawnmower part saved the day for this problem. Daan Quote Link to comment Share on other sites More sharing options...
