Anglo-Frenchman Posted December 11, 2006 Share Posted December 11, 2006 Sorry to raise this again but last time I had no replies. I have changed the front output seal on the LT230 transfer box recently together with a new flange as the old one had a groove in it. None the less I still have a leak and am at my wits end as to why it should have failed. Could it be that I simply did not seat the new seal in properly or is something more sinister? I'm getting fed up with the stench of hot EP90 every time I get out of the 110 and would lke to be able to park it without leaving splodges if oil everywhere. Any ideas?

Les Henson Posted December 11, 2006 Share Posted December 11, 2006 Check the breather isn't blocked. The front output bearing does tend to be a bit sloppy, but a certain amount is ok. Are you sure it's the seal that's leaking, and not just looking like it is, but the oil is in fact coming from somewhere else? Les. Quote Link to comment Share on other sites More sharing options...
Anglo-Frenchman Posted December 12, 2006 Author Share Posted December 12, 2006 Thank Les, I' ll have a look at the breather. I'm pretty certain its the output seal beacuse when I first changed it it cured the problem for about 1000km then it started again. How fool-proof are the seals? Also what about the little felt washer under the retaining nut? Can this let oil pass by? Thanks again, Ged Quote Link to comment Share on other sites More sharing options...
Les Henson Posted December 12, 2006 Share Posted December 12, 2006 The felt washer prevents oil from passing up the splines and then out of the flange where the nut is. Some oil seals are very poor quality - depending on make obviously. Is there any chance that you didn't put the seal in far enough and the lip has been rubbed away by the back of the flange? It's a common mistake to put a seal in with the outside of it flush with the housing, whereas the highest part (which sometimes is the centre lip), should be level with the housing. Les.

white90 Posted December 13, 2006 Share Posted December 13, 2006 get a genuine seal, and I'll wager the breather in blocked/restricted having changed too many seals to many times Quote Link to comment Share on other sites More sharing options...
Les Henson Posted December 13, 2006 Share Posted December 13, 2006 You should start a seal club then Tony - you're friends from GreenPeace might misunderstand and come round your house and be rude! Les. Quote Link to comment Share on other sites More sharing options...
Anglo-Frenchman Posted December 14, 2006 Author Share Posted December 14, 2006 Thanks very much for the info. I'll check out the breather and also I've ordered a new seal so I'll give that another go as well. Regarding the installation of the new seal, I have been using my hub box spanner as a tool to knock in the seal but find that the round chassis strut is positioned perfectly to get in the way of swinging a hammer. Is there an easier way of pushing this seal in and also how far should it go in? Until it stops or before that point is reached? Thanks Quote Link to comment Share on other sites More sharing options...
Les Henson Posted December 14, 2006 Share Posted December 14, 2006 The highest point of the seal should be flush with the housing. With ordinary flat seals-there is no specific area that is higher than anywhere else on the face of it. However, there are now double-lip seals, and this type of seal has a higher centre. When using this type of seal the main body of the seal actually ends-up what would seem to be too far inside it's housing. This is a picture of a 110 brake disc/hub assembly. This is the same type of seal and you can see what I mean about it looking like it's in too far. Les. Quote Link to comment Share on other sites More sharing options...
Anglo-Frenchman Posted December 14, 2006 Author Share Posted December 14, 2006 Thanks Les. From your picture and description it appears that I have been knocking the seal in too far. Quote Link to comment Share on other sites More sharing options...
