sevenmad Posted October 9, 2011 Share Posted October 9, 2011 Today I finally got round to removing the diff from my Roadsport to send it of to R&R to have an LSD fitted. At the same time I thought I'd replace the oil seal on the back of the gearbox (for the prop) which has consistently leaked since the build 18 months ago. Having got the prop out my question is how to get the old seal out? Its exceedingly tight and leavering with a flat blade screw driver won't budge it. Is there a technique? What am I doing wrong? I presume the new seal is just drifted in with a hammer. Link to comment Share on other sites More sharing options...
Eugene Posted October 9, 2011 Share Posted October 9, 2011 What gearbox? I usually manage with a large flat-blade screwdriver, but it is a bitch. Just make sure you are leveraging the oil seal, and not the lip of the casing it sits up against. When fitting a new one get it as 'flat' as you can when drifting it in... Good luck!

sevenmad Posted October 9, 2011 Author Share Posted October 9, 2011 Its a 5 speed. Obviously access is limited in the tunnel and I'm worried about damaging the seat for the new seal. Ever tried one of those hooked seal puller? seen some one ebay and wonder if they work.here Link to comment Share on other sites More sharing options...
Eugene Posted October 10, 2011 Share Posted October 10, 2011 I think that's likely to cause more damage if you get it wrong!!!! 😳 Link to comment Share on other sites More sharing options...
sevenmad Posted October 11, 2011 Author Share Posted October 11, 2011 Thanks, I take it no sealant is required beteen the seal and its housing? Link to comment Share on other sites More sharing options...
Domus Posted October 11, 2011 Share Posted October 11, 2011 Make sure there are no scratches in the bore, oil will track and weep. I always smear a little Hylomar on the outside of the seal. Mind you, air compressor seals have to deal with higher pressures than gearboxes but I still advocate it. Link to comment Share on other sites More sharing options...
sevenmad Posted October 20, 2011 Author Share Posted October 20, 2011 I really suffered trying to get the seal out with a screwdriver, so bought a seal puller from ebay for £8. With the puller it took 15 secs, with no risk to the bore. Highly recommended Link to comment Share on other sites More sharing options...
