My recently acquired 1981 R100 was impressively oily....on the outside, and had signs of a long standing crank rear oil seal leak.
The engine is out, clutch and flywheel removed and to be honest I think the culprit is just as likely to be the oil pump O ring...(which I will look at next)....but having come this far, bought a new type oil seal and spent a morning turning up a tool to fit it I want to finish the job.
I have got as far as you see in the photo.......if it works ..... but the crankshaft end boss is very firmly in place and I'm extremely reluctant to use any force for fear of damaging something. Looking at it.....I would guess at some sort of clamp around the part that sticks out at the centre and a decent slide hammer.
I guess I could fit the seal around the crank end boss, but I'd rather use the tool I went to some trouble to make.....any constructive advice to remove the end boss without damaging anything......or a method that avoids removing it would be much appreciated.
