fender1234 Posted April 8, 2009 Share Posted April 8, 2009 Hi all, I had a nice surprise this morning of noticing a small puddle of ATF on my drive So i crawled under and had i look and took a picture its an lt77s by the way: It seems to be leaking from somewhere and running down and dripping off the drain plug and the transfer box cover bolts. The gearbox was rebuilt about 2000 miles ago so i would be surprised if it was the mainshaft seal, does anyone have any ideas of simple things i can check? (the drain plug is tight so dont think its that) thanks in advance Quote Link to comment Share on other sites More sharing options...

Les Henson Posted April 9, 2009 Share Posted April 9, 2009 Best way is to clean it off and then keep an eye out for where it's coming from ( a can of Brake and clutch cleaner will blast it off). If it's the gear/trans box mating point, then the gearbox seal is leaking here- Transfer box off I'm afraid pop the old seal out and press a new one in. A bead of silicone in a continual line around one of the mating faces will help as well. If you just silicone it, then it's possible that the gearbox oil might find it's way into the transfer box, which you'll know nothing about until it's too late. I'm pretty sure the oil seal is part number FRC4493 or FRC2365 - dependant on suffix number. Les. Quote Link to comment Share on other sites More sharing options...
zim Posted April 9, 2009 Share Posted April 9, 2009 you put that a hell of a lot better than i just did, i've been browsing microcat to see if i could find a decent picture to show which seal i meant, but a photo is a lot better it's ATF coming out the back of the gearbox Gordon Quote Link to comment Share on other sites More sharing options...
fender1234 Posted April 9, 2009 Author Share Posted April 9, 2009 :(i had a feeling this might be the case is there any point trying to find anywhere else that it could be coming from or is that the only real place and should i just accept it and crack on with taking the transfer box off Quote Link to comment Share on other sites More sharing options...

fender1234 Posted April 9, 2009 Author Share Posted April 9, 2009 Ok thanks Les and Gordon. Any tips for changing the seal? should i put a self tapper in the seal and then pry the seal out? and should i tap the new one in with a hammer and a peice of tube?

Les Henson Posted April 9, 2009 Share Posted April 9, 2009 should i put a self tapper in the seal and then pry the seal out? Yes, but take care not to damage the alloy housing nearby. You'll feel the drill 'pop through' the seal, so be prepared for it and go no further. Screw a self tapper in and then yank the seal out. Les.

fender1234 Posted April 9, 2009 Author Share Posted April 9, 2009 Ok thanks Les. I dont suppose you know the part No for the seal do you my LT77 is a 56A, and also the seal that goes in the transfer box LT230 22D Quote Link to comment Share on other sites More sharing options...
Les Henson Posted April 9, 2009 Share Posted April 9, 2009 Defender LT77 is P/No FRC2365 LT230 is either FRC2365 (to (T) 677403), or ICV100000 (from (T) 677404G) Les. Quote Link to comment Share on other sites More sharing options...
fender1234 Posted April 9, 2009 Author Share Posted April 9, 2009 thanks for that, you've put lt77 seal and lt77 seal as the same no are they the same part, they look like they could be. Quote Link to comment Share on other sites More sharing options...
Les Henson Posted April 9, 2009 Share Posted April 9, 2009 Yes, both seals may be the same. If you want to get the seals in advance, they just buy all 3 - they are about £2 each Les. Quote Link to comment Share on other sites More sharing options...
fender1234 Posted April 9, 2009 Author Share Posted April 9, 2009 good thinking where would you recommend i buy them from? as i would like a decent quality seal. Quote Link to comment Share on other sites More sharing options...
Les Henson Posted April 9, 2009 Share Posted April 9, 2009 Genuine would be best, but then expect to pay double that or perhaps more. Paddocks, Craddocks, Bearmach, etc, should be able to supply genuine items, but make sure you specify that. Les. Quote Link to comment Share on other sites More sharing options...
