tpk241 Posted July 24, 2007 Share Posted July 24, 2007 Hi All, I have a leak where the gearbox meets the transfer box. I am looking to sort this ASAP. Anyone got any advice for me on what to look for / what parts to get .. ? Should i be replacing mainshaft oil seals etc .. ? Is the seal between mating faces just an RTV sealant ? Many thanks TPK Quote Link to comment Share on other sites More sharing options...
Pete Attryde Posted July 24, 2007 Share Posted July 24, 2007 Mine does the same ,also a 300TDi Auto. Mine is definately leaking ATF so I am going to replace the gearbox output shaft seal (P/n RTC4650). Not sure what else is involved will find out when I do the job. Pete.

stripy Posted July 24, 2007 Share Posted July 24, 2007 i had this problem on my 90, it was leaking ep90, turned out to be the "o" ring on the end of the shaft that holds all the transfer gears in place. transfer box out, but a very cheep repair Quote Link to comment Share on other sites More sharing options...
stripy Posted July 24, 2007 Share Posted July 24, 2007 also ment to say when you pull the transfer box out get some 180 10mm bolts cut the heads off, then as you take a bolt out of the transfer box replace it with the 180 10mm rod, then you can easley slide the transfer box back away from the main box without damaging the oil seal. 5 bolts in all , if memory serves me right.

Les Henson Posted July 24, 2007 Share Posted July 24, 2007 There are two seals when you seperate the gearbox and transfer case. ATF is from the gearbox and EP80/90 is from the transfer case. Because the seals are so cheap I would recommend you replace both of them while you're at it. Also put a bead of RTV sealant between the two. It's very easy to damage the one in the transfer case when you are struggling to put it back on the gearbox. The long bolt method definitely makes this less likely to happen. Les.

tpk241 Posted July 24, 2007 Author Share Posted July 24, 2007 Excellent thanks all ... I give it a go shortly . I phoned a local garage out of curiousty to see how much they would charge to sort it, it was 190.00 plus VAT .. Quote Link to comment Share on other sites More sharing options...
