Yes, when renewing the fluid flywheel oil seal, it isn't necessary to remove the engine.triddell wrote: ↑Tue Sep 14, 2021 9:30 am This thread has been very useful for me, so thanks Mike for asking, and for the responses. I need to replace the oil seal on my LD10 transmission, and had thought that you need to take the engine out to do it, which I dreaded. However it seems on reading the references in the answers above that since the gearbox can be taken out in the car, while leaving the engine in place, then I won't need to take the engine out to replace the flywheel oil seal. Is that right? I'm still not sure whether I could get at all the bell housing fixings.
On the Daimler DB18 Consort the gearbox has to come out under the car. In some of the threads in the Daimler forum section, some people managed to renew the seal with the bell housing and fluid flywheel still in place, but the Daimler workshop manuals suggest that the fluid flywheel is removed (which requires bell housing removal).
According to the LD10 gearbox removal instructions, the gearbox can come out inside the car http://ld10.awardspace.co.uk/bay/gearboxremoval.htm , with the bell housing still attached (at least, that's the way I read it). If the LD10 is anything like the DB18's and Conquests, I'd remove the gearbox from the bell housing and then remove the bell housing separately. Not having seen the transmission in an LD10 I wouldn't know, but it makes more sense to me to firstly remove the gearbox from the bell housing, giving more room to access the bell housing - or maybe to renew the fluid flywheel seal in the same way that some people did on the Daimlers.
