Dremel flex driver functionality restored
Without the driver cap (which I had somehow misplaced/lost), my Dremel's flexible drive shaft was useless. eReplacement offered the replacement at a very reasonable price. I'm a happy tinkerer!

Tools Used
, Torx driver, needle nosed pliers, Dremel specific wrench
1. Diagnosed problem to be both worn brushes and bad variable speed/on-off switch
2. Ordered replacement parts needed and decided a new armature with attached bearings would be a good investment in saved time and extended tool life between repairs
3. Verified unit was unplugged, removed end nut
4. Removed hanger bail, brush caps and brushes. One brush was jammed -see note 9
5. Removed housing retainer screws and positioned tool upside down before splitting
6. Used plastic scraper to gently split tool casing open. It would not part by hand
7. Removed power wires from old switch, making careful note of which wire color went where based on the position of the switch. If there were any guide marks I couldn't see them so color/position was important to reassemble properly.
8. Removed armature and switch together
9. Removed rubber isolation washer from rear bearing and then used diagonal cutter to break old switch bridge so I could remove it from the armature - it just wouldn't come off any other way and it was obviously bad. After removing armature/switch from case, clean both case halves.
10. Positioned new switch over new armature and reinstalled the rubber isolation washer
11. Installed new switch/armature into casing, take your time and work gently
12. Re-installed power wires into switch, they are a push in and lock type, smaller needle nosed pliers are great for this
13. Positioned power wire strain relief in case and worked the two case halves back together, then verified fit and reinstalled screws to lock it closed and reinstalled hanger/bail
14. Installed brushes and brush caps, then drive nut for flex shaft
15. VERY IMPORTANT - after verifying free spinning of armature when unplugged, I plugged the tool in and did a ramp from slow to max speed start, about five seconds between start to full speed, and then let the tool run with no load for five or six minutes to wear in the brushes. I hung the tool up in open air so it could ventilate and also blow away any brush dust from the run in.
16. Tool works great and the cost of the parts to make it better than new was less than buying a new grinder. The job was fun and should not be beyond the skill set of anyone who owns and uses one of these tools. .
