Thread: Convert RR+Disco Wheel Bearings to Oil Lubed?

I note that item (13) is not there in the earlier drive flanges [item (11)] on earlier Discos [pre 94(?)] and RR Classics - a solid, one piece, capless drive plate end.

yes, that's all there is to it.
Michele's drawing is showing a post '94 'fender front end with the plastic dust cap.

Whew!.....at last,.....I've NOW got it!..........It's soooo simple AND effective ......

Thanks to all the guys who helped out on this!

That diagram is different to the one for my Disco. I'll post up a pic of my diagram in a minute.

So if you remove part 23 the oil will flood as far as part 7 but not into the wheel bearings as far as I can see. So if you were to remove part 7 then the oil will reach the bearings. However I don't see how theoil is stopped from running out past the dust cap?

I think I will just have to buy two of those RTC3511 seals and pull it apart to see for myself.

On my March 93 build date Disco and on previous RR Classics I've owned, there is no cap on the end of the drive plate/flange. So that's not a problem on the earlier set up........you just make sure the gasket under the end plate/flange is really good or better still, use a GOOD quality RTV silicon to make a good oil-tight seal here.

I'm pretty sure that the dust cap is on versions where LR switched over to the inferior swivel housing method of "lubed-for-life" grease and also had no drain or level plugs on swivel sphere housings.

So where does the RTC3511 seal actually go. I'm starting to think if I have oil in my swivels then I don't actually need to change to these?

If you've got a Disco 1 1994 "update"/ "300"/ larger square headlamps and bigger front blinker lenses and lamps in rear bumber bar - then I think you've got the later grease filled spheres without the level and drain plugs in them, only a fill plug and with the caps on the drive plates - can you go and have a look please and get back on that? .....it would solve a few queries.

Do any of you guys know about this DEFINITELY???.....What month/year build date did they change over
