I have a 1970s argo with a Kohler engine. The Bosch starter isn't working so I pulled it off, but now I can't get it apart to clean the brushes. I removed the 2 long bolts that run through each side of the casing, but it wont come apart. From videos of other starters it appears that the round cylinder case should just pull apart, but Im not sure if it comes apart at the end with the bendix or just the other end where the brushes are located. has anyone repaired one of these before?
