Do you think hitting the end of the crank with that hammer is a good idea. Seems heavy to me.. I was told many times never to hit the crank to fit it.. To easy to put it out of alignment.
+kevin swithenbank @ 0:24, no problem (except for the bearing), but @ 1:00 , you're right: no good. The principle is that the fragile part is the center of the crank, where the rod head bearing is. When you need to remove or fit a crankshaft, any force must be applied on the same side of the crank the tight-fitting bearing is; not the opposite side. That means, on a Lambretta, acting on the chain side of the crank, by tapping it out for removal, and pulling it in when installing. When tapping it out, one must also be aware that the shocks are absorbed by the bearing, so the bearing should be checked afterwards, or changed outright.
