If you have a Skil 88 (SPT88-01 or SPT88-02) with a faulty motor, then this guide will help you to do a quick replacement to get it working once again. What is a Skil 88 Motor? It is a drill from the STP88 series that uses a motor in order to convert electrical currents in order to power it so it can drill through tough objects due to the fact it is powered using a motor. If the motor were to become faulty, then the drill would not be able to be used at all as that's its power source. This fix should be easy for any person no matter their experience with repair or replacement. Some warnings that you need to know about is that first make sure that the device is disconnected before replacing to make sure it does not accidentally turn on and that when removing parts, they may fall off so be prepared for if that does happen. Once you have made sure it is turned off, you can get started.

  For reassembly, remove the orange cap on top using your flathead screwdriver. A bushing should come out with it.
  
  Depress the bushing on bottom using the tweezers. To reach the bushing you will have to put the tweezers through the "Skil" lettering. Insert the motor as it is depressed.
  
  Using the tweezers, place the other bushing back in through the hole in the top. Screw the orange cap back on.
