Midwest RDH Prophy Nosecone Repair
Disassembly (Note: Complete Nose Assembly is now
available, part# 40534. $119ea. As of 10/2011)
STEP 1
Insert a 9/16” Collet into your table mounted
collet holder. Next, insert the handpiece threads
into the collet and secure. Then, wrap the upper
portion (Nose section) of the RDH with a strip of
Gum Rubber (00032). Once tight, slowly jiggle
the nose section while also pulling up. This
should release the nose section from the main
RDH Body.
STEP 2
Insert your 00014 MW Nosecone wrench
into the opening on the bottom of the nose
section. The two teeth on the wrench will
exactly match the notches in the internal
nosecone nut. Pushing hard into the nut,
unscrew in a conventional counter-
clockwise motion. This will allow you
to remove the internal nosecone main
spindle assembly.
