Hub Nuts & Bearing Seals

[Pilo-Wedgebits]

Hi guys,

I'm looking to replace the hub nuts on the 350. My local fastener stockist thinks the nuts are M22 x 1.25 pitch does anyone know if this is the case? Does anyone have experience of the steel locking nut instead of the nyloc - i'm told it is better.

Also to add insult to injury the guy that put the seals back in the hub carriers has put them in back to front me thinks - steel to the outside - rubber in.

I need to get my hands on four of these - does anyone know a source and does anyone know how far they should be inserted

Cheers

Shaun

Lock washer and nyloc is my preferred option,bearing seal is mk2 granada inner seal times 2 i think and metal is usually on the outer so you dont damage the seal when you tap it in,but my spare set is somewhere safe so i cannot check it for you.Tempus

If you find where to get some metal lock-nuts let me know. This style of lock-nut is used on the inboard end of the driveshaft because the heat from the brakes would melt Nylon. I believe that in aviation applications Ny-lock would be considered as one use and discard whereas an all metal (deformed thread) self locking nut can be re-used many times so long as increased resistance is felt upon re-assembly. Personally I use this philosophy with Ny-locks which means they tend to get discarded after half a dozen uses or less whereas an all metal version would last me a lifetime.

From memory the all metal lock nuts go under trade names like Aero-tight and K-lock not sure of the spelling though.

FWIW For hub nuts (and bearing in mind the repercussions of auto-disassembly/destruction/death) I currently use Nylocks with the addition of a low grade liquid thread-lock applied to just a few scrupulously cleaned threads. I have bitter experience of using too much thread-lock and what a complete bleep of a job it was to undo! I would very much like to upgrade to all metal lock-nuts with the same liquid thread-lock scheme.

David Gerald TVR supplied me with some lock nuts about for the rear hubs 2 years ago, may be worth trying them.

Hi Tempus,

The thing that puzzles me with metal out is that this opens up the spring / spring seat in the seal to the outside world whereas rubber out = complete seal

Note sure re. term 'metal out' but the lip / seal / wire faces in - both sides. Primary use is to keep the grease in but also cr*p out
NOt sure about nut spec. I bought new nylocks from RT. Metal locks tend to be longer there may not be enough thread.

The lips of the seal should face inwards i.e. towards the bearings,so assemble that way whatever.i will try and find my spare seals and see if they are the same way round as yours.Tempus sorry left it on reply and did not read .

Have you tried any of the wedge suppliers .. TVR Car parts, RT etc..

Also just take the old nut along to an automotive nut specialist .. luckily I found a really good one near me (Guildford).

Unfortunately my nuts have no thread left to talk about as previous owner damaged threads on shafts and nuts.

It is Margnor..

I've not taken a hub nut to them yet but have never failed me for any other odd nuts and bolts I take down there..
