monkey welder Posted January 29, 2023 Share Posted January 29, 2023 Hi to all you knowledgable landy owners out there - please can someone tell me whether or not the seal in the attached pic is the right way round? It is on the rear hub off a series 2A LWB and this is how the seal came off the vehicle. I'm having to renew it thanks to it leaking and here's my confusion: every seal i have fitted has always been lipped side facing away from you and towards the bearing, and yet this one is the opposite. Have i got it wrong or has a previous owner got it wrong, the manuals are as clear as mud? Thanks. Quote Link to comment Share on other sites More sharing options...
Gazzar Posted January 29, 2023 Share Posted January 29, 2023 That's wrong. And a mystery as to how it was done. Spring should be IN whatever you are sealing. 1 Quote Link to comment Share on other sites More sharing options...
monkey welder Posted January 29, 2023 Author Share Posted January 29, 2023 Thanks, just what i thought and confirms which way i'll put the new one in. Quote Link to comment Share on other sites More sharing options...
Retroanaconda Posted January 29, 2023 Share Posted January 29, 2023 They’re quite often double-lipped seals and so in that case there will be one visible whichever way around it is fitted. Quote Link to comment Share on other sites More sharing options...
hurbie Posted January 29, 2023 Share Posted January 29, 2023 i don't think you have enough space to fit this seal the other way , because off the lip sticking out Quote Link to comment Share on other sites More sharing options...
monkey welder Posted January 29, 2023 Author Share Posted January 29, 2023 The replacement seals are pretty standard with a lipped side and a flat side, so i'm still guessing the flat side should face me.....?? Quote Link to comment Share on other sites More sharing options...

Correct. The photo looks like a double-lipped seal to me, and it appears the correct way around as the writing is visible on the flat face of the seal carcass and a bigger lip appears to extend down towards the bearing.

Northwards Posted January 30, 2023 Share Posted January 30, 2023 The photo is the old seal, yes? Could you pull it out and photo both sides? That way I think you'd get something more definitive. I haven't seen that many of these, but I don't think I've seen one with that spring on the outside. 1 Quote Link to comment Share on other sites More sharing options...

Now that I zoom in, it looks like you are right, it's a "h" profile, rather than a "u" profile. My mistake! Remove the spring and shorten it, might stop the leak. What's the land like?

The seal in the photo is a double-lipped seal and is fitted correctly. If your new seal is single-lipped then fit it with the lip on the inside - flat face on the outside. If it is double lipped then fit it same as the one in your photo. 1 Quote Link to comment Share on other sites More sharing options...
Snagger Posted January 31, 2023 Share Posted January 31, 2023 The seal might not be fully seated down in the bore, they may be a defect in the bore or on the seal land (the bit of the stub axle the seal runs on) or the seal could be defective. Check the depth from the hub rim to the so,d seal face for evenness and post up photos of the stub axle. Can you read the manufacturer’s name on the seal? If it’s anything but Angus or Corteco, it could well be the problem. If unbranded, then it is likely to be the problem, probably originating in China or India and sold in a blue box pretending to be British. “Britpart seal” is an oxymoron. 1 Quote Link to comment Share on other sites More sharing options...

That seems to make sense and might be why i'm getting conflicting answers - i've never come across a double lipped seal. I need to get the seal out and have a look at it to verify - the replacement seals are single lipped anyway so i guess will have to be fitted as described.

monkey welder Posted January 31, 2023 Author Share Posted January 31, 2023 Just a random thought... How do you press a double lipped seal in without distorting the lip?? Quote Link to comment Share on other sites More sharing options...
Retroanaconda Posted January 31, 2023 Share Posted January 31, 2023 With a seal fitting tool that has a recess for the lip, or something else of a similar size. Before I got the proper tool I used to use an old single-lipped seal with the lip cut off, which bears nicely on the outside diameter of the new seal without disturbing the lip. 1 Quote Link to comment Share on other sites More sharing options...
Northwards Posted February 1, 2023 Share Posted February 1, 2023 If you have an old wheel bearing (for that wheel hub) you can sometimes use the outer race to tap in the seal. Cut a slot in it with a grinder or hacksaw, and the thinner side of it should rest against the flat face of the seal without affecting the lip. 1 Quote Link to comment Share on other sites More sharing options...
monkey welder Posted February 2, 2023 Author Share Posted February 2, 2023 Well, it was after all a double lipped seal, how odd, i'd just never come across one before.. Thanks for all the advice! Quote Link to comment Share on other sites More sharing options...

Retroanaconda Posted February 2, 2023 Share Posted February 2, 2023 RTC3511 is the double lipped seal that fits the Defender hubs, and possibly the later Series III hubs too if they use the same size seal land (been a while since I’ve had an Series III apart to remember). I use it on all of mine as I find it is better at retaining oil and grease, and keeping water out. 1 Quote Link to comment Share on other sites More sharing options...
Northwards Posted February 3, 2023 Share Posted February 3, 2023 Thanks very much. Not knowing about these, I’ve just used the ‘standard’ ones with the single lip facing outwards, and have a small stock for convenience. Once they’re used up I’ll look at making the switch.

monkey welder Posted February 3, 2023 Author Share Posted February 3, 2023 That's good info. All that is stamped on the ones i have removed is 315-236-15-DR but as the RTC3511's are so cheap i'm tempted to buy a pair and measure them up.

monkey welder Posted February 4, 2023 Author Share Posted February 4, 2023 Oh dear, the new seals i bought do not fit.. Perhaps the old seals being double lipped indicated that the hubs are from a series 3 and maybe late series 2's could have had later hubs fitted..? I'll have to get the specs of the RTC3511 and see if they fit. Hey ho. Quote Link to comment Share on other sites More sharing options...
