Midwest Shorty Single Speed Motor
The Midwest Shorty single speed motor has been in existence for many years. It is a
durable handpiece and has a speed range of 0 – 5000 rpm. It has replaced the Midwest
Tru-Torc and you will come across them quite often in the field. Many aftermarket
replacement parts exist for this handpiece. As always, try to determine the problem
before disassembling the handpiece.
Some of the most common problems and solutions are addressed in the Midwest Tru-
Torc and Shorty troubleshooting guide immediately preceding this section.
Sub Assembly A & B Disassembly
STEP 1
Remove the front sheath housing. Do this by
placing it in a 3/4”collet. All the threads on this
handpiece are regular thread, so turn
counterclockwise to remove.
STEP 2
Lock the drive housing of the handpiece into a 61/64” collet. Loosen the
upper turbine housing by hand and remove. Remove any spacer
washer(s) and keep them in a safe place.

STEP 3
Reach under the drive plate with a flat thin screwdriver. Pry the plate
up. This will expose the three wide drive rings. Place them along side
the drive plate on your work surface.
