GKT Posted September 26, 2017 Share Posted September 26, 2017 I've got the gearbox out of my 1973 series 3 SWB Petrol for a clutch change and notice the crank oil seal is leaking. Can I replace the seal without taking the engine out? Quote Link to comment Share on other sites More sharing options...
Daan Posted September 27, 2017 Share Posted September 27, 2017 I am afraid it is rather involved as you need to take of flywheel and bellhousing. I supppose you could try moving the engine forward in the chassis and do it in situ, but it is rather delicate that way. Daan Quote Link to comment Share on other sites More sharing options...
GKT Posted September 27, 2017 Author Share Posted September 27, 2017 Thanks Daan. I've got it stripped down, removed the two bits around the seal and can see the actual oil seal. Looks as though it's been bodged with clear mastic. Quote Link to comment Share on other sites More sharing options...
Daan Posted September 27, 2017 Share Posted September 27, 2017 I hadn't realised your box is out already, so that is perfectly possible. On the 3 bearing it is a split seal, which need heating up in some boiled water to stop the rubber splitting. Daan Quote Link to comment Share on other sites More sharing options...
GKT Posted October 6, 2017 Author Share Posted October 6, 2017 Thanks Daan. Having a go this weekend. Nice tip about warming the seal. Mr. Haynes never mentioned that. Quote Link to comment Share on other sites More sharing options...
