Has your Voskhod broke again? Suffering dodgy Italian electrics? Post your tales of woe here. Or ask odd questions about the rear wheel spacer on a Vincent Black Widow, should it take your fancy.
Some engines however you fit the crank seals and then the bearings so using an oven is not an option in those cases I usually use a decent heat gun and something like a oversize bearing driver (remember a rag or gloves before you grab the handle to remove it) the bearing driver will shield the seal and allow you to heat the case so the bearing out of the freezer will just slip in.
