I am about to attempt a rebuild on my E3L with replacement parts purchased from Hawker Electrical in the U.K. And I am wondering if there are any special gear or bearing removal tools I will need for the job or any advice anyone may have in general. Thanks
Greg, You will probably find the drive end bearing loose in it's housing so a bit of Loctite would not go astray on assembly. You don't say which E3L you are overhauling but the ones with drive gears, the gear normally can be prised off with two screwdrivers adjacent to the keys but the BSA type with the sprocket on a taper is a bit more difficult. To remove the armature from the drive end, I support the housing and drive or press the armature out.
Don't want to diminish your efforts or anything, but there's a gent here in PA who is positively astonishing at Dynamo fix. I took mine to him on the July 4 w/e; he checked it, replaced and fixed all that was necessary and had me on my way inside an hour. The cost ? $50. His email is firstname.lastname@example.org My only connection is as a very happy customer.
Thanks again guys. Got her apart (not so easy, lots of pullers, etc) and now the gear, bearings, oil seal etc are all back in place. Next question is does it matter which field coil wire goes to earth, etc. They are both black and the originals were both orange. thanks.
