Dremel 7300 MiniMite Cordless Motor-Shaft Assembly Replacement

Difficulty

Easy

Steps

Time Required

5 minutes

Introduction

If the motor burns up or the power switch breaks, you are going to need a whole new motor and shaft for the device, as they come as one piece. This guide will show how to dissemble and remove the motor-shaft assembly.

Tools

TR10 Torx Security Screwdriver

Step 1

Pull back on the release tabs to disconnect the battery pack from the housing.
When installing a new battery, you may need to charge it before using it.

Step 2

Remove the two screws from the back of the device with the TR10 Torx Security screwdriver.
Make sure you have removed the battery before proceeding as accidentally powering-on the device while disassembling is dangerous due to the high-speed components inside.

Step 3

Lift off the unscrewed plastic cover at an angle, away from the tip of the device.
Gently lift the cover. It won't take much force to remove it.

Step 4

Lift the tip of the motor-shaft assembly gently, then pull the assembly out.
The blue battery contact and the spring for the shaft lock button may pop out when you remove the motor-shaft assembly. Make sure to keep track of these pieces, as they are very small.

Conclusion

To reassemble your device, follow these instructions in reverse order.

Ok the blue part the battery connection battery to motor. Popped out and I put back but it's not making connection to motor or battery. I tried spinning for different angles but nothing has helped. Motor still good and battery still has charge. It's just connection between the two. All parts still together. What am I doin wrong
