I did a full rebuild on the weekend for a friend, installed the seals AFTER the cases where closed up with some loctite with my thumbs and a piece of solid timber/lumber and my steel hammer…..tap tap tap tap.
I wish I had that special tool to make it a bit easier but as people have said, its not rocket science and I only do this job on people’s CR125’s maybe 3 times a year.
Bro, bearings/crank are not slip fit from factory, if it was meant to be slip fit don’t you think the factory would have done so? Same goes for CR250. People may prefer the slip fit mods for convenience.
PS….Bro, does the pronunciation of your name sound similar to the 44th President of the United States?
