You don't need to remoce the cable. Just disconnect it by unscrewing it from the adapter and then remove the adapter. The seals are in the adaptoer.

red67 Posted October 14, 2020 Author Share #52 Posted October 14, 2020 How do you remove the adapter from the transmission? Do you just put a channel lock on it and twist? Should it Just pull out? Could be leaking where the cable screws onto the adapter? Thank you! Link to comment Share on other sites More sharing options...

red67 Posted October 14, 2020 Author Share #54 Posted October 14, 2020 Ah, thank you! See from my pic, it seems to be leaking from above this point too. Like around the shifter area. What could be leaking there? One thing leads to another. Thanks again! Link to comment Share on other sites More sharing options...
EuroDat Posted October 14, 2020 Share #55 Posted October 14, 2020 Yep. There is a cotter pin for the selectors above the speedo cable adapter. It often leaks a little oil over a long period. Yoer adaptrr is leaking through the pinion shaft seal. The o-ring seal looks like it is still ok, but you should always replace it too. They harden when they get old. Once you remove and refit them they start leaking. I think I mentioned it earlier. To remove the adapter, just remove the M6 bolt and tab above it and the use a flat bladed screwdriver in the groove where the tab was to pry it out.

EuroDat Posted October 14, 2020 Share #56 Posted October 14, 2020 (edited) The oil leak from above is most likely from one of two places. 1. The cotter pin in "red circle" or the o-ring for the selector "blue circle". There is a third spot, the lip seal "green circle" in the selector mechanism, but them your selector stick would be leaking out the back or top where the gear stick goes. Green circle is where it would leak fron. The lip seal is further in the selectors Edited October 14, 2020 by EuroDat Link to comment Share on other sites More sharing options...
red67 Posted October 14, 2020 Author Share #57 Posted October 14, 2020 Thank you everyone, job done! Pinion seal and O-ring are in. Everything cleaned up hopefully as you said it was the pinion shaft seal that was leaking. One question the metal tab with M6 bolt, looks like it should go in the slot on the top of the adapter. Mine was all the way in, and that’s the way I replaced it. But should the tab be in the slot? Follow? The other areas discussed look more like sweating, than a leak so I cleaned it up and let it go for now. Thank you again!!! Link to comment Share on other sites More sharing options...

(serv.man. are at www.xenonzcar.com ) And.. yes the tab should be in the slot.. Edited October 15, 2020 by dutchzcarguy Link to comment Share on other sites More sharing options...

The slot also determines the position of the gear since the gear is off center from the hole it sits in. So if you pushed past the slot the gear could be too deep and on the wrong axis, too far or too close, if the slot is not where the bolt is. Found a cool cutout picture of a gear installed. Different brand, same concept. http://www.gtsparkplugs.com/SpeedoGearCalc.html 2 Link to comment Share on other sites More sharing options...
