I am currently restoring an Atco HY and need to completely strip down the rear roller in order to get to the pawl mechanism. I am stuck and have not been able to remove the spherical bornze bearing at one end of the main shaft. It looks as though a collar on the end of the shaft should unscrew. I have been unable to move it at all. Any advice? There is a hole on the circuference of the smaller diameter of the bronze bearing. Does this contain a grubscrew?
Any advice you can give me will be very much appreciated.
