???Hi everyone,can any one help,can the front pulley oil seal on the 33/44 engine be changed with the engine in place and without splitting the crank cases? All my work on these engines in the 60's and 70's was dismantling and rebuilding on the bench, so this seal was fitted during the rebuild.I know the process needed to strip to get at the seal, but having never tried to change the seal with the engine in situ I would appreciate any comments!! Thanks starider.

I've just changed the front seal on my 33. Not rocket science.
Howk the old seak out with a long screwdriver. Lubricate the new one with eng. oil and offer it up to the orifice. Using a hard wood or plastic drift of suitable width ( I used a bit of 1" square scrap mahogany)and a leather hammer, tap it in gently moving the drift round the seal as you go. When the drift hits the crankcase you are in far enough!
Although the old seal was well gone, the mating surface of the crankshaft pulley was pretty near perfect.
I reckon if you have a groove in the crankshaft pulley you can probably get away with it by not knocking the seal right in. Leave it (say) a sixteenth proud of the crankcase (Don't know what a sixteenth is in millimetres!).
Regards,
Pete.

I agree with Pete, should be no problem, just looked at an engine I have strip down on the bench, but do not knock it to far in, only when the face is flush with the casing as there appears to be no lip to stop it.
