Racingshoe Posted August 10, 2007 Share Posted August 10, 2007 Spent a joyous afternoon wrestling with my car to get the 5-speed box out and get the new 6-speeder in. Had to change over the speedo drive, but can't help but feel that a little brass collar held in with a circlip is going to keep the oil from leaking out. Is there meant to be anything else in there to make a seal? Rik Robarts - the future's bright, the future's orange here Link to comment Share on other sites More sharing options...
rgrigsby Posted August 10, 2007 Share Posted August 10, 2007 Don't think so and also don't think it's unusal for them to leak a bit.. Rob G www.SpeedySeven.com Link to comment Share on other sites More sharing options...
Mark w Posted August 10, 2007 Share Posted August 10, 2007 There should be a black rubber seal around the speedo drive ,fitted before the brass collar and circlip. It will still leak though !!!! Link to comment Share on other sites More sharing options...
Bricol Posted August 11, 2007 Share Posted August 11, 2007 Not always - mine did on first build - a new seal cured it 5 years ago - no leaks since. (and there is still oil in it!) Bri Link to comment Share on other sites More sharing options...
Racingshoe Posted August 13, 2007 Author Share Posted August 13, 2007 Thanks for the replies. The 'box is weeping oil from the brass-hat area just sat on the garage floor, so i'll look for a seal before popping it in the car. Link to comment Share on other sites More sharing options...
strij Posted August 13, 2007 Share Posted August 13, 2007 I had a leaky speedo drive, changing the oilseal did not cure the problem. After dismantling and close inspection the metal sleeve on the plastic drive shaft was found to be slightly loose. This sleeve provides the hard polished surface for the oil seal to seal against. It should be tightly crimped on to the shaft. The oil was going under the sleeve and bypassing the seal. A previous owner had tried using silicon sealant around the oilseal which would never have worked. A new shaft/gear cured the leak. Link to comment Share on other sites More sharing options...

Mick Day Posted August 14, 2007 Share Posted August 14, 2007 I solved mine by removing the drive, installing a blanking kit (standard Ford part I believe) & fitted an electronic speedo off the front wheel. Link to comment Share on other sites More sharing options...
