I have a ‘46 Berk I’m working on that runs good forward, but is much slower and noisy in reverse. So I was wondering:
1) How much endplay should there be in the armature shaft? Mine has about 1/8”.
2) How much end play should there be in the lower horizontal worm shaft? Mine has about 3/16”.
3) What is the proper length of the brushes and brush springs?
Thanks,
AC
