I am working on my parents' old Heritage II, bought new in 1987. I have inherited it since they inherited a newer Kirby from my grandfather when he passed six years ago.

Front bearing went out, and I have it completely disassembled on the bench. Years ago, I replaced the motor brushes and switch for mom and dad. I ordered a number of other parts to replace since the thing has been going for @ 25 years.

I have a new armature, new field, new bearings, etc. I'm curious about a couple of things:

1. How do I press the new bearing onto the commutator end of the armature?
2. Where exactly does the internal speed switch screw into (it was just hanging there when I opened the case)
3. What break-in techniques should I use to start this thing up for the first time?

Any other tips anyone wishes to share will be appreciated. I am waiting on a couple of parts before I can put it all back together, including a new motor bell housing - the old one had to be cut off as the bolts were seized/rusted holding the field into the bell housing.

When all is said and done, I will still be in this vacuum cleaner for less than a decent new one!

Also, I ordered a new front motor housing with bearing. The old one got messed up trying to put the new bearing in the front. Although these are supposed to not be press-fit in, the new bearing certainly needed pressing, and I pinched the retaining clip railing enough to crack a piece of aluminum out.

I really miss my old arbor press!

The bearing on the commutator side can be tapped on by using an old fan pulley.  Just be sure that you're tapping on the inside race of the bearing.  I always just wrap the armature shaft in a cloth and clamp it down in a vise before tapping the bearing on.  It provides more stability.  Also, it's been a while since I've worked on a Heritage II, so I can't really remember how the speed switch is set up.  I do remember that it is a more complicated arrangement than earlier models.  Can you post any photos?

I will take a few when I get back down there with everything. Thanks!
